Ultimately Nuclear energy is the way to go and if walk-away safe Thorium Molten Salt reactors is only an interim solution for the next 30 years when Fussion makes it to the market, so be it. Your excellent unbiased, open minded to Nuclear energy, channel is worth a dozed David Borlace's "Just have a think" closed-mind-to-TMSRs Channel which is inevitably so frustrating to watch. - thank you🥝🥝🙏
Fusion will not work. We are not even sure it is the driving force inside a star. However, we are so sure that we can replicate it here on Earth. If even 1/10th of the resources spent on fusion had been spent on Thorium Molten Salt Reactors we might be mining the asteroid belt already AND actually be 30 years away from fusion.
@@mdebarshi That was discovered in 1989 (Ponds and Fleischmann). Just a few years ago NASA published research on the exact same phenomenon and all but called it Cold Fusion.
I really don't see you why we're trying to create fusion reactors on earth when we have a huge fusion reactor right next door. Why not just find a way to collect more of the sun's energy from orbit? with the amount of money that's been spent on this pipe dream we could have created a way to collect more of the sun's energy by now
Breeding lithium into tritium is a huge hurdle that may turn out to be impossible at a rate that can compensate tritium losses. This isn't even being addressed by the current fusion research such as ITER. It was glossed over by the expert in this video
Thank you so much Matt for asking me about my opinion on whether this fusion breakthrough will be a game changer. In my whole career in retail, nobody has ever asked me my opinion on nuclear fusion issues. I know the world will be a much better place, and nuclear fusion can now advance much faster with the disclosure of my opinion (since I am exquisitely qualified to comment on the subject matter as a retail worker and youtube video watcher). My opinion is : Looks good to me.
@Peter Evans man, solar isn't happening on an industry and city level. its but a excuse for gas industry to remain relevant... don't Believe me, just look at the difference between Germany (pro-renewables) and France (pro-nuclear).
Thanks for the great news. My Dad was an engineer at the Plasma Physics Lab at Princeton University. They built several fusion reactors as I was growing up starting with the C Stellerator and ending up with a Tocamac. The Tocamac reached what was called break even back then in about 1979. The the lab was a joint venture with Princeton, DOE and Westinghouse as I remember. When Three Mile Island melted down the funding for the lab started drying up. The supper conducting materials and the ability to create better vacuum in the chamber were the big obstacles at that point. It is great to hear MIT is making progress on the magnets. Maybe with RUclips’s like this we can have a better public understanding of the difference between fusion and fission. If the fusion work at the Plasma Physics lab had continued there would be fusion generators producing carbon free electricity right now! That was about 30 years ago. Keep up the good work! John Joyce
I've never been one of the cynics, mainly because I understand how important materials development is in a bigger project like this, and that we're making breakthroughs almost every month in one way or another. As this story shows, something created in the 1980s is now being used in a new way thanks to developments in application and manufacturing. It takes a million small discoveries to reach a major breakthrough. I'm convinced we'll get there.
Right,but the main breakthrough is the ReBCO SC tape.Power scales to the third ppowernof the magnet field strength, so twice as powerful 16 times the power.
We had TRISO fuel 20 years ago we have it now, never melt, never fail, simply the coal and gas lobby which is also the renewable lobby has delayed TRISO until now, it is the same material SiCarbide it is extremely tough, we've had it forever. Plenty of steel is perfectly suited for molten salt reactors we've had them for decades, right now, there are pots of hot molten salt we are watching to see if it corrodes the steel alloys.
@@mikehunt1528 true I live in USA and in some other countries power is cheap to the point where it’s almost free but unfortunately some countries are greedy and charge more cause they can USA should be less greedy and focus on making everything cheaper and better overall
I tend to be of this mindset: As long as a scientific field sees regular improvement that corresponds with theoretical goals, then I am optimistic. If a field sees significant stagnation for long periods of time, then there is cause for concern. Any scientific innovation will be "always 30 years ahead" until it one day finally exists and functions as intended. That's just the nature of working with unpaved paths and no known variables to adhere to. In reality, no one knows when we will see commercial fusion reaction - but we see regular exponential improvement and that is a damn good sign. And don't forget, that along the way, all this research will also trickle down into other fields that find use in the same research and proofs of concept - just see how much technology developed for Aviation and Space exploration has found their way into our daily lives through totally unrelated contexts. Innovation is never wasted, no matter the field.

@@nonconsensualopinion which they have been doing for decades. If they put a tenth the money and effort they put into fusion into fission, there would be no carbon emissions.

Old enough to remember back when "fusion reactions" were mostly wildly complex formulas on a professor's blackboard. You can tell it's getting more real now that the story is shifting from large, expensive, multi-national experimental concept reactors to an actual startup developing a more practical design. The recent breakthrough was a big step in that direction, but it's going to take several more big steps like that to shed the "30 years away" label.
Well, fusion reactions were considered possible decades upon decades ago. The problem was getting tech/materials/etc. to where a first step into it properly to persue this stuff. Every scientist back in the day with funding could have easily created the reaction...but time always comes later...so it didnt happen...pretty simple and no world bending news that it is now and not 50 years ago... We have nothing of interest to persue and money extracted out of other humans somewhere else, so that we can now finance our stuff. 😋
The issue was harebrained over-excitable types selling it before it was ready even for solid research. It isn't at all late really compared to other power sources if it comes in the next 25-50 years, it'd still be faster than solar ha
If in fact, we had really widespread adoption of fusion energy within 30 years, that would be great. That assumes that we have practical reactor designs within 10 or 15 years. I am assuming these things take a few years to build at the very least. Not only that, but the infrastructure needs to be built up for extracting D2 from seawater in high quantity. In order to build out enough fusion power plants to supply most of our energy will require hundreds of billions just for the cost of the power plants. I think all these things should and will be done, but expectations that we will have a demonstrated working and efficient fusion reactor today and a transformation of our global energy grid tomorrow are just unrealistic. It will take at least 20 years to build out enough power plants for the US.
I helped in the manufacturing of the large stainless steel vacuum chambers that contain the high temperature superconductors for MIT 👍 - Welding Inspector here.
In the 90's it was 50 years away.. Now it's been 30 years, and we are 20 years away according to most people... Hmm, maybe we actually got it right with the timing 😂? So, 2040 it is
From the first fusion devices up until 2000 fusion gains were doubling every two years - then we hit a wall The SPARC magnets should put out a Q of 10, over ten times the point where we stopped. Being built in 2025 that means we are potentially increasing at the speed of Moore's Law again. One or two such jumps beyond SPARC would be the starting point of commercial potential technology Maybe even one half step. For instance ITER's whole facility efficiency is about break even. The pilot power plant based on ITER would use about 50% more input energy and put out 1000% more power. There may be a similar jump from SPARC to ARC which they hope to build before ITER begins deuterium - tritium plasmas in 2035
@@MichaelHayesagent The optimistic view is that a positive total power balance will be demonstrated in 5 - 10 years. Then another 5 - 10 years for a potentially commercially competitive pilot plant. That's the big if - it should be possible to build a plant putting out net electricity on a commercial scale but there will be engineering and economic hurdles due especially to the super energetic neutrons damaging the plants. There is a new neutron shielding tech being tested by Tokamak Energy next year. Basically I expect a commercial level of power output to be achieved by 2035 - 2040 but I wouldn't be as happy to bet on a commercially competitive fusion design to come out in that time
When I think of fusion, I think of the scope of the engineering and the supportive science. When we finally get this, it'll be one helluva party. Hope I'm around to witness.
@Ray Wyman. I too hope I'm there to see it BUT for reasons entirely unnconnected with their work, unless they protect our freedoms, all will be lost. There is one great elephant in the room that these clever scientists at the top of their field will not address. The evidence is there in the video. They are complying with government directives that they wear masks, which their fellow scientists have proved that they don't control the spread of the disease and possibly harm the wearer. . They therefore are ignoring the government's own Vaers figures that show the deaths and other harmful effects of the jab. (if I use the correct term, my comment will be removed). The CDC are now advocating jabbing children. The facts are out there, but they choose to get on with their work without standing up to the unlawful control being used to change our society which eventually will destroy all they have achieved.. Am I right in likening them to building a sand castle on a beach while ignoring the incoming tide? Scientists, please wake up. We need your outspoken support. Please spend some time discussing this with your colleagues. You are used to dealing with facts and changing how you proceed in future. Seek out the facts . If you don't your valuable work on Nuclear Fusion will come to nothing.
I’ve been following the R&D of nuclear fusion, both magnetic and laser containment, since the late 1970’s. This breakthrough in superconducting magnets may be what we’ve all been waiting for. Thank you
I am really curious how the HTS tape works under the high neutron flux they will be exposed to under actual working conditions! Based on the locations in the periodic table.... not so well. 30 years away and always will be. Take a look at Brillouin Energy.

It’s probably not going to be possible
There was no out-of-control chain reaction at Fukushima, the reactor was completely shut down in time, there was not enough cooling for the short lived decay products due to collapse of surrounding infrastructure and bad placement of backup generators
And complete flooding of generators and backup batteries caused by bad/dangerous design. Coupled with a complete lack of safety procedures it was only a matter of time.
@@artsmith103 If reactors are built save, they wouldn´t be as cheap as they are (actually, even then they are expensive as hell). I was skeptical of fusion before, but I am optimistic that these inventions can actually bring nuclear fusion a good step closer.
This calls to mind a scifi story I read as a kid: a multi-generation colony ship arrived at their new home after traveling for more than a century only to discover it had already been settled utilizing a faster transit method.
Lmao this happens in the game Outriders. A despot left behind on an apocalypse Earth manages to develop a stronger engine and beats the hero's colony ship to the planet by decades, creating a fucked up warworld upon your arrival
It's not that simple though, ITER still has advantages: 1) Q factor is also related to Tokamak diameter, refitting it with high temp superconductor coils would beat CFS, 2) ITER are also going to try out Lithium Blankets around the chamber to make new tritium fuel to feed back into the process.
Yeah it is quite extraordinary that after all these decades, nobody has been able to come up with a better way of converting heat energy into electricity. If someone was to come up with a more efficient way of doing that large scale, that would be an incredible breakthrough.
Some advanced reactors were made to use gas turbines which are not so new discovery. Molten salt reactors are so energy dense it doesn't really matter if they use steam turbines because they are much better at harvesting energy from the fuel.
Ironically, the nuclear part is what holds the highly advanced steam technology back in that case. The greater the difference between the hot and cold side of a heat engine, the greater the efficiency. Coal plants have all moved to supercritical steam (i.e. hotter steam) whereas nuclear reactors remain constrained by the cores to much lower and therefore less efficient steam temperatures.
A lack of citations and tech. publications around this 20T magnet is a bit disconcerting, though. Why the cloak-and-dagger? Where is the opportunity for someone else to replicate their experiments with a commercial REBCO tape to build a 20T magnet and conform their findings?
Their "High temperature superconductor" also seems to be a misnomer. Traditionally, Y1Ba2Cu3O7 (YBCO) superconductors are considered "high" temperature because you can use (relatively cheap) liquid nitrogen (LN) to get them superconducting. These are unfortunately not able to withstand the typical 6T - 12T magnetic flux density inside a typical MRI-bore; a liquid-helium cooled "low-temperature" superconductor is traditionally essential for this task (and also for the LHC at CERN and for other facilities). If someone claims "20T HTS" - I would interpret this as "a superconductor that can be realized with liquid nitrogen, capable of producing 20T". This is not the case. The REBCO material here needs -254'C instead of -269'C (i.e.. 19K instead of 4K) . This is a big achievement, sure, but not quite "HTS". There goes the LN-cooled-MRI out of the window :( .. for now.
@@AdityaMehendale Tokamak Energy built a 20T magnet from commercial ReBCO tape in 2019, it's just circular rather than the D shape needed for their reactor at the moment though.

In fact, your precious "renewables" are a byproduct of fusion, it just doesn't require us to maintain the reaction (the sun, if you didn't understand).
Her video is mostly about ITER and JET, and about those, she is right. However,she explicitly ignores alternative, smaller approaches like MIT Sparc (and there are more commercial companies reseaching fusion).
As a science fiction nerd who read Analog and Galaxy magazines as a teenager in the 1970s,many things were supposed to take place in 30 years,Cold fusion,Moon Colonies and a New ice age. At 65,i most likely don't have another 30 years to wait for these things.Controlled Fusion is like Lucy moving the football on Charlie Brown.
Matt, I was a nuc in the Navy in the 70's and we talked a lot about fusion in school (which was over a year long). We all thought Fusion would be a reality by 2000 but seemed to fade from the discussion over time. It is very heartening to hear that such progress is finally being made and Fusion might actually be a reality. If it is, we will solve the worlds carbon problems and provide power for a world hungry for it. Love your videos!
Fusion funding is consistently cut in half, doubling the time needed. This breakthrough for this is piggybacking on a breakthrough from the 1980s? Imagine if we had the funding to put more brains on this 40 years ago. Would this breakthrough have happened in the '90s? or still take 40 years? Imagine the Nuclear power if the Manhattan Project was given a continuously shrinking budget every time they had a breakthrough. Look at how long it took Iran, Pakistan, India, North Korea et al to figure it out with lower budgets.
@@wack-a-n00b81 It's a salient point. We're still using the same power distribution system from the days of Edison and Tesla....mainly because the guys controlling the purse strings like Westinghouse wanted to keep billing customers for the system they had paid to build. Further innovation would mean ripping it all out and rebuilding, which would cost a fortune. And here we are today with basically the same highly inefficient systems.
@@AllFlimmits Essentially, yes! Corporate lobbyists buying politicians. Getting money out of politics would be a massive step forward but it's really hard when all the policies are basically bought and sold by people with financial interests in the big game of coal and oil.
To put this into perspective: the strongest permanent magnet ever made was 4.5 Tesla. Everything else until now required an insane amount of power, so this is great news.
Thanks, good to know However, I would say that comparing the magnetic field (20 tesla) with that of ITER or an operational reactor would be also an interesting perspective 😀 I found "a maximum magnetic field of 11.8 tesla" on ITER's web page.
@@snygg1993 I think the difference is the location. The 11.8 seem to be within or near the coils. In the middle of the donut, where the plasma is, it's only 5.3 Tesla.
Fusion power has been one of those Sci-fi tropes I was always fascinated with, can't say any other technological breakthrough makes me more excited than looking forward to deployment of fusion as a viable source of energy.
Fusion tech is far away. Are tech energy sector is crappy. Thorium is far better as a Fission element less radioactive material. Which is the problem governments like to use uranium because it makes plutonium which other governments will buy for nukes. Look it up! Plus thorium makes more energy per ton. Now it would cost a crazy amount to make a reactor with thorium because one of the US presidents decided to go with uranium he was from that state and I'm sure he was paid off. Yeah keep spending billions on fusion plus this man says they are only on for seconds 🙄 u know why tell them the plasma breaks their weak tomahawk. 20 tesla u say at 20ka shit. Can't u run a nuclear reactor to make gold for cheaper.) Uhg my brain hurts. However I thank you for your video seriously people like you make me strive to be better and find a solution. When I do I will share but never with any government. Cheers!
I worked as a contractor on TFTR Tokamak Fusion Test Reactor , twice in the 80's. DOE was great to work for and the project was great fun. Lots of very smart people working there (do to its contercycle funding) we called it the technological WPA)
HTS-110 in New Zealand has been making HTS devices since before 2006. We have made 5T systems in great numbers. Systems are being used in a wide variety of scientific and industrial applications. Part of the reason HDD reached terabytes was from HTS devices used in the manufacture. I was the Senior Production Engineer with HTS-110 for 10 years.
3:16 "causing a nuclear meltdown or explosion". Worth pointing out that the explosion is not like a nuclear fission bomb, it's more like a conventional explosive, admittedly one that can easily scatter radioactive material all over the local area, or toss it into the atmosphere. Causing an actual nuclear explosion takes very specific conditions like highly enriched uranium or plutonium and large amounts of implosive force.
And there's plenty of catastrophic failure modes in a fusion reactor as well. Quenching of the superconductors, implosion of the vacuum vessel, failure in the power electronics that drive it... those will all result in a 'significant boom' kind of scenario. Although the chance of it releasing radioactive isotopes is a lot less - the hazards are much more local.
@@Stoney3K Not really. There is no "significant boom" in a fusion reactor accident. Remember, a fision reaction is happening naturally in enriched fissile material of critical mass. The job of a nuclear reactor is to manage that reaction and keep it from turning uncontrollable. If significant parts fail, you loose control. A fusion reaction, requiring extremely high temperatures and pressures, does not happen unless it is forced to happen. And the whole setup of a fusion reactor is designed to force it. If any significant part of it fails, that just means the fusion reaction will just fizzle out. Remember fusion only happens if you heat a gas to the point of being a plasma, and then magnetically compress it into fusing. If it drops below the temperatures needed for plasma, then it losses it's magnetic characteristics and expands, and if some part of the magnetic system fails, it expands as well, cutting out the fusion process.
While that's true, apparently in the Chernobyl incident it's been hypothesised that a small section of the reactor did actually have the neutron environment necessary to go prompt critical.
@@michaelt.5672 This is based on Uranium reactors though. Thorium reactors can't melt down, and its why they should be adopted instead. They also produce much less waste than uranium does.
There was no runaway chain reaction at Fukushima. There were cooling problems leading to radioactive decay overheating. Similar to TMI. The Soviets, on the other hand, gave us prompt criticality inside a coal bed. One big spark that lit the whole plant on fire.
there's never going to be a better fusion reactor than the Sun. And it's already putting out all the energy we need to populate the solar system and explore neighboring stars. We need nothing else. Not in space, and not here on the ground. The Sun does everything any species could need to leave the solar system. These technologies aren't about need, they are about consolidation and control. You can own the fuel, and the machines, and the debts of workers. You can't own sunshine. But it does provide free energy everywhere in all directions. All we need is a way to capture it and use it efficiently. Concentrating it should be left to the R&D budgets of the massive corporations trying to capitalize on concentrated deployment. MIT should be out working on the carbon density of global productive soils right now. Not profit metrics for theoretical energy companies of the future... yall know the planet is turning into a desert right? The soil is our carbon battery and the sun is our fusion reactor. Nerds, put your enormous throbbing brain on the table and do your thing. We all gonna die if you don't... Figure out some solutions that work in a mud hut in Africa, AND the suburbs. Real technology. For humanity... so we can keep living. Right?!?!?!
@MrGriff305 Unfortunately the energy output of a human is inefficient for running any kind of machine. However, our brains more advanced than any computer will likely ever be at the same size and energy efficiency. Using us as a server network to perform computations and run the simulation of the Matrix would be more viable.

While, I think it would be nice to have nuclear fusion reactors that actually work I think we should strongly consider Thorium Molten Salt nuclear reactors as a viable temporary solution because they can be made relatively safe compared to the giant nuclear reactors there’s no worry about a runaway reactor core because there’s a plug that basically drains the reactor core into a safe into a safe container where the reaction can no longer take place. These can be made safe and small enough so that small communities can have their own reactors and protect the possibility of blackouts due to one or two reactors going off-line for whatever reason. The smaller Thorium Molten Salt nuclear reactors will be able to generally take up the slack. After watching the entire video on this new breakthrough in a smaller and equally powerful magnetic containment field I am more hopeful for nuclear fusion that I was earlier. I still think we need to still go forward with Thorium Molten Salt nuclear fission reactors.
Um the US government made an Integral Fast Reactor that is unable to reach melting point. So we should do more research on the IFR design than ordinary Molten Salt Reactors.
Safety is not the big issue with nuclear reactors - COST is. It's an expensive way to boil water. Why would either thorium or fusion, be cheaper? Proven and relatively unsophisticated reactor designs simply cannot compete economically with other renewables, why would completely novel cutting edge designs?
@@kenoliver8913 *Small Modular Reactor* designs essentially eliminate the COST argument against nuclear. COST being an artificial constraint anyway, easily addressed if humanity were to unite around nuclear energy.
I've been fortunate enough to be very close to what I call "big science'" my entire career, the publicly funded fusion experimental machines MFTF for a few years, the SLAC upgrade from LINAC to rings, then the National Ignition Facility from design through commissioning, and into operations. Noteworthy physics and engineering breakthroughs aside, the big question for me is this: Will private investors maintain the motivation and 'have the stomach' to forge past the latest challenges, will project leadership be able to constantly 'sell it' to keep funding pouring in? If not, then the technology isn't quite ready for this next privately funded phase.
Will private investors maintain motivation...it would be so amazing to change the mainstream narrative about the future. The scarcity story about overpopulation and doomsday global warming, that we have imo very little control over, what if it flipped into a "wow, look at this frontier we can take part in" kind of story?

It has quality. Do you think with the powers of media that are currently terrifying everyone, telling us humans are certainly a cancer, and we will die in a fiery inferno- this weird heard it before religious pattern - what if that power of media became captivated with this story, inviting crowd source type money to the new energy sources.

I wish more could be said about molten salt fission reactors. They don’t have of the safety detriments spoken of herein, don’t take large plots of land, don’t require access to water source, and are over hundred times more efficient than existing fusion reactors (light water). Experimental reactors like this were already made in the 60’s and 70’s. They don’t need a huge energy kickstart like fusion, and they don’t mess around with the meaning of Q factors like fusion always does (Q is never just energy in over electricity out, which is what it should be).
true, though i def feel we will probably discover the magnetic field issue with fusion reactors far before we figure out the Corrosive issue with MSFR's....but shit at this point who knows.
@@JustinKrux the corrosion and tritium issues have been solved (Hastelloy-N and supercritical CO2 turbine generator). I guess my point is, if a fraction of the money spent on fusion had been spent of MSRs, the West would already have them in the field. As it is, China is the only one who has one.
Tony Hill (Former director of INL {Idaho National Laboratory} ) is currently on this exact mission; head to head battle with Bill Gates....Gates is pushing hard for thorium salt reactors.
@@randalljsilva I thought Hestelloy-N was not yet the answer? My current understanding of the issue is that neutrons bombarding the nickel. The nickel would then go through Alpha decay and those helium atoms would lodge in the grain structure. This would then make the material become very brittle over time leading to cracks and leaks in major structural components.
It seems pretty game-changing as far as field strength, but plasma stability is still a major concern. Moreover, the stronger the field/confinement, the more difficult it is to maintain stability.
i remember watching a show called 21 up that followed a group of people through their lives every 7 years and one of them at 21 was working on a fusion reactor and was optimistic that they would figure it out within a few years (this was in the 80's). A few decades later he was a math teacher and said he would be surprised if it could be figured out any sooner than 100 years
it's a big part of why I don't begrudge fusion researchers always being 30 years away from a working prototype - we're the equivalent of renaissance-era scientists knowing the semiconductor transistors are possible, but not knowing exactly how to make them, and using all of our pre-industrial ingenuity to figure it out from scratch.

The "smartphone" (exemplified by the 2007 iPhone) was the confluence of a powerful, energy efficient chip plus better battery plus better screen plus better network speed. Same may happen with fusion, you just need to be able to make all the parts to drop into place.
Also, once that net power gain goal has been achieved, the focus can shift to scaling up and increasing efficiency, while automating production. The first car wasn't built on Henry Ford's assembly line either.
The initial iphone was worse than other smartphones at the time. The only thing it had going for it was Apple marketing and a more user friendly interface. technology wise it was behind. It took many iterations of the iphone before it caught up in tech to the other phones on the market. If I remember correctly the 5 was the first one that was caught up. When they were up to the 4, they still didnt understand how to build antennas even, which resulted in Steve Jobs actually telling someone they were holding their phone wrong... since if you held the phone in specific ways(which were normal ways of holding a phone, just not the way steve jobs held a phone) it disrupted the antenna
Another aspect of what youre saying is that we had the technology to build an iphone in 1980 but it would have cost billions of dollars. So the only thing you can do is wait.
The power of a reactor scales to the third power of the magnetic fields these magnets being the same side but provide 10X the power,I can see why you would not think it important, you must follow the science closely.
@@paulbedichek2679 It doesnt solve the problem of the blanket, or the problem of how to get tritium without needing immense amounts of lithium, and so on. Its a piece of the puzzle. And its useful in other fields of science. Thats it. Doesnt mean nuclear fusion will be "ready" in time to prevent climate change, still way off that target. So, yeah, its good progress, but nothing to get hyped about.
"Just another"? Why so dismissive? Every piece is just another until you get to the last one that joins them into a whole. The problem is that often the developer of the last piece gets the whole of the credit. In reality, every piece counts and contributes, and often not to just one type of problem.
Thanks for the update on this effort. Over 35 years ago I had the opportunity to join a SDSU field trip to visit the tokamak experiment at General Atomic in San Diego. I was thoroughly blown away, and hopeful for this technology to advance. I’m happy to hear that major strides are being made, and I await my Mr. Fusion powered Back to the Future DeLorean someday soon…
Played some game years ago that was about managing a nuclear fission reactor, and it turned out to be fairly realistic. Dunno why, but it made something click in my brain, and I realized I actually really enjoy learning and teaching people about them. Nuclear fission/fusion reactors are just weirdly badass. If it weren't for Chernobyl, I think we'd have quite a few more people cheering it on.
Fukushima if you examine it was actually a success story. An old design survived the 4th most powerful earthquake on record and the resulting tsunami with only causing one direct death and far less environmental damage than standard coal plant operation, let alone when one of those goes tits up.
@@cubosquare6724 No idea now, sadly. I haven't been able to find something like it either; makes me wonder if it was a flash game or something that got purged.
This talk of fusion reactors misses some key issues: 1- How to continually extract helium out the plasma and keep optimal ratios of deuterium and tritium. 2- How to transfer excess of heat generated in a safe way to another fluid so to generate steam for turbines to move electrical generators. 3- Find a different way to generate electricity from plasma without using thermal cycles to produce work.
1.Yes, breeding tritium in practice is an unsolved and rarely mentioned problem. 2. Yes, while running superconductors in the same room. 3. Good luck with that!
Missing the v point you are converting to heat energy to do work. The amount of work from any heat engine is related to difference of temperature in the hot and cold wells, that's why power plants have cooling towers
On #3, if part of the process of fusion is stripping electrons away from deuterium/tritium to create helium shouldn't there be a time interval between stripping the electrons away to produce the ionizing plasma and the 'reconstitution' phase creating helium, wherein the temporarily freed electrons could be used to induce an alternating current directly into a motor/turbine? No need for steam?
@@pierrechildress8875 that probably only will be able to recoup partially the energy that was required to get the initial gas into a plasma. Not the energy necessary to heat and pressure the plasma into the the conditions necessary for nuclear fusion. Also most of the energy will be in the form of heat, and for helium ions charge neutralization there is the need to spend energy in separating from the plasma. And even with their charge in neutral most of the energy is still in the form of heat. And at this stage you will need to rely on thermal cycles, and that means that for fusion reactors the Q number needs to be very high as to overcome all the inefficiencies that will occur in the process of generating electricity.
Magnetic biomechanical fly- wheel core. Cold liquid electromagneified liquid gas to cool the walls of the reactor and feed the reaction. Acoustic magnogravitational outer mechanics to keep the reaction stable and compressed or kept in uniform
for those interested: there is a correlation on how hot the plasma needs to be vs how strong the magnetic field is. Plus there is also an interesting proposal on using liquid surfaces for plasma-facing components. And I agree - must suck for iter folks to work on something that is going to be hopelessly outdated by the time they are done
Correct. ITER is a joke and frankly should be disbanded entirely. It’s the completely wrong direction for fusion now that we have REBCO superconductors.
There's a ton of research going on with ITER that goes beyond just a "proof of concept" for a net energy production fusion reactor. We just don't know how these materials change over long time periods (greater than fractions of a second) of operation.
Did not expect any news this year, given ITER's continuous delays. That's pretty exciting. Can't wait to read up on the details. It's even better that there are good news, since ITER has also finally stopped being so mismanaged at long last.
@@paulbedichek2679 ITER has a bad rep. but I think it's essential to consider it is not only a facility for achieving fusion. It's an experiment where all kinds of fusion related technology will be explored. As far as I know, ITER's big contribution may be in things like shielding materials capable of withstanding the high ammount of neutron radiation, knowledge about high energy plasmas and confinement, etc. Which probably will help advance other fusion designs.
Who cares about ITER that is European approach Americans are building the SPARC reactor much cheaper faster and smaller.Also like Canadas General Fusion. you smack spining ball of lead with a bunch of hammers.
@@paulbedichek2679 You do realise the US is one of the countries building ITER, right? Scientific research is about cooperation, not competition. Peace!
@@b.6603 Yes,I support ITER and have followed it for decades,but they won't produce much, not a working reactor,SPARC will beat ITER by decades,General Fusion is also a viable fusion pathway, lots of ventures, besides ITER.
These guys should really team up with the guys at Hot Pockets to learn how they were able to achieve near-fusion temperatures inside of a buttery, flaky crust.
Several Problems, First the Net Q energy release was only compared to the energy needed for the massive laser or Q Plasma, it did not include the energy required to run the actual reactor (Q Total) which has massive electromagnets and all kind of conduction systems. Also all that was produced was heat, not actual energy, they are extrapolating the heat produced into the electricity it could produce, which is another entire energy requiring process. And also the Tritium is really rare and we do not have quantities at Scale and Scope and to manufacture Tritium requires enriched Lithium-6, not a fun substance to have around. The ITER Reactor experiment will use half of the Tritium on earth by itself. This is all Hopium Squared.
The quiet part nobody says out loud is that fusion isn't really clean. Fusion creates tons of gamma rays and high energy neutrons (actually much more than fission reactors). 80% of the fusion reaction's energy is in the form of high energy neutrons that need to be absorbed by something and converted into heat in order to use that energy and whatever materiel is being used to absorb the neutrons will slowly become radioactive over the years by means of neutron activation and will eventually have to be disposed of somehow.
Maybe it's easier for fusion than for fission, choosing some isotopes we can reprocess. Certainly has less nuclear weapons proliferation risk, and the radioactive half-lives can be shorter, and the radioactive concentrations lower. But still a bit dirty inside the recycling loop.
Great update Matt. As for fusion, I have a bottle of wine set aside for the day fusion energy is harnessed for commercial use. Thankfully, it gets better with age and hope to drink it in my lifetime.
As an apprentice engineer around 1971 I was shown a newspaper headline on a fantastic new line of research “Fusion Tokamak” and a major breakthrough that could supply free energy for all. I’ve now retired 50 years later, STILL WAITING. I’d like to say I’ll believe it when I see it but now at 66 years old another 30 years away seems unlikely.
I remember being about 7 or 8 y.o. and people were talking about it. Now I'm 44, and I figure I'm gonna croak first. On the other hand, we're seeing some electric vehicles now, and even if they aren't cost-effective yet they're certainly very energy-efficient.
From what I have read, it isn't true that fusion reactors wouldn't have a nuclear waste problem. The reactors and blanket materials will become highly radioactive over time and then there is the waste from the fission nuclear reactors which are required to make the tritium component of the fuel. No free lunch and it's more than 30 years away seemingly.
I think it doesn't matter if "fusion is always 30 years away". Fusion *is* the ideal energy source, the proof that it is only an engineering challenge, not a physics challenge, is literally in the stars, and so we simply have to keep trying to solve the engineering challenge. And we are. So bring on the jokes, and bring on the fusion power plants. They will change the world like nothing has ever done before.
That's what I always keep thinking about. I mean we literally did achieve fusion many times already, so we can kinda say we did " It " already. Only problem is making it more efficient, but a few years ago I thought fusion was impossible unless it is in a star, and yet here we are, not trying to create it ; but just make it more efficient
One issue is that a star is a truly awful fusion plant, it takes 5 billion years to burn a small fraction of its fuel, and it is huge. The problem we have is that we need a much much better power plant than this, which isn't automatically possible, though it is looking like it is
@@daveansell1970 I'm not an expert but how is it awful that it takes 5 billion years? The energy released by the sun in 1 fraction of a second is still way enough to sustain Earth (if we could harness it of course)
Energy transport over long distance could be a key too. After all we already have an 100% efficient fusion plant in the middle of the solar system. I wonder how much would have been achieved on the subject with the same fundings.
"MIT and CFS are now aiming for the stars!" Maybe literally. Fusion, if we ever get it going, could be the most reliable source of energy we've ever developed, and could allow us to get back into space.
If fusion comes online it would totally destroy all those who invested trillions into solar and wind. There's more to it than just building a fusion reactor.
I have been involved with fusion since the early 1960's at LLNL. MFTF, NOVA, Shiva, NIF, ITER, and believe fusion is our only option for the future. I have no idea about 30 years but it will come!
Fusion reactors are a complex engineering endeavor but I have no doubt that we'll eventually have them. We are still at a stage that theoretical knowledge into fusion, materials science, and engineering breakthroughs are still needed that will have to come together for a functional reactor. These stronger magnets are another step towards the goal. I just hope that my 67 y/o body and mind will survive long enough to see fusion reactors come online. Then onward towards fusion powered space vehicles for exploring the solar system and nearby star systems.
Viewing this on Nov 5, gotta say it's by far the most important news of the day for humanity, and is buried beneath all sorts of politics and pandemic news! Well, maybe second most important, as ABBA is releasing a new album today 🙂
It's either this or they actually need a breakthrough in solar energy, 15 yrs and they still can't do better than 20% efficiency, not viable or cost effective, wind isn't dependable enough either.
Will the new fusion reactor really be boiling water to make electricity as one commentator pointed out or will it be able to covert the reaction directly into electricity? Converting directly to electricity seems possible since plasma is involved and part of the plasma is made up of electrons freed from the nucleus of basically water atoms.
I was in grad school in the 1970's, when fusion power was 30 - 50 years away. I guess the Tokamak was beginning to emerge as the most likely answer about then. There was also the Stellarator, and the mirror machine; can't recall whether inertial confinement (implosion of D-T pellets, driven by lots of high-power laser beams) was coming into play at that time or a bit later. Well, here we are 50 years later, and the Tokamak design still looks like the winner; the others having largely faded away. At least there are starting to be prospects for success in less than 3 decades. I'm encouraged by this news; I'm not popping any corks just yet, but this actually could finally turn the corner on this. There are just so many hurdles still to clear, that it's way too early to go bonkers. Fred
These videos put my mind at ease knowing there are alot of work being done on energy storage and production. I see a future where there is a perfect green energy production and storage options for everything.
One afternoon about 45 years ago, I came home from school and opened the issue of Science News that had arrived in the day's mail. It had an article about a "fusion breakthrough" that made it sound like they'd cracked the problem and that usable fusion was just a few years off.
Gene Roddenberry from star trek must of known about this even earlier in the early 60s .. as the Enterprise was powered by magnetic fusion in the form of a plasma reactor
mike rayner videos - It was matter-antimatter reactors, not fusion reactors, powering the Starship Enterprise… with Dilithium Crystals in their cores regulating the reactions.
My elder son works at General Atomics' D3D facility, so I have a bit of a second-row seat on fusion. Amid the hype, genuine progress toward making fusion practicable is finally being made. The real breakthroughs may indeed come from some of the smaller, more nimble players.
Why keep demonizing fission?? It's most likely the only real way to reduce carbon emissions from electricity production in a fast, meaningful and reliable way. Fission deserves much more focus and support to improve it's economical viability. It's benefits far outweighs the risks, which are incredibly small in new gen reactors, and waste is far more manageable than most people think.
Exactly. That is why the BREST 300 is manufactured in Russia. A safe nuclear reactor that uses radioactive waste from today's nuclear power plants as fuel.
Yeah the waste is managable but not only is the fuel limited the waste is basically permanent, it is not a permanent solution to energy think of it like coal, it was insane when it was first discovered but in the end it had to be changed for something better, also fusion in theory can be far more powerful than nuclear, has nigh infinite fuel and has virtually no way of melting down, it also doesn't produce any waste in fact could use nuclear waste as fuel, but I would never demonize them they are incredibly useful and arent even that volatile
@@MonsterPumpkinHowever, there is still a lot work to be done in the field of nuclear fusion. By the time the experimental fusion reactor continuously produces more electricity than it consumes, many standard nuclear reactors will be built. That is why it makes sense to invest in nuclear waste reactors, just like the BREST 300. We now have a huge amount of such waste.
I'd say it's a game-evolver; just as what happened in aviation, in automotive, in electronics, etc. I believe there is indeed room for enthusiasm but certainly not room enough to fit such dramatic words as game-changer yet ...at least, at this stage. Great vidéo, subject and research, though. 👍 Cheers
No one doubts how great nuclear fusion reactors would be - if we could get them to work. But given the need for clean power now , it would seem that putting money into thorium reactors may be a better solution for the time being.
It seems we are still well over a decade away from a Q sufficient for meaningful generation. And once we reach that milestone, we still must replace all that entrenched fossil fuel generation, so slap another decade or two on top of that. Regrettably, Earth just can't wait that long. Dare I say it, fission is the best stop-gap we have until then.
Thorium reactors are a pipe dream. Don't pay any attention to Utube videos that brag about all the good parts. Some of them exaggerate, some of them are just plain wrong. Thorium has a downside, which is why *no major organization in nuclear energy has invested in it.* I'm no physicist, so if you want to know more, you'll have to research it.
@@daedster1 Ok, I should have been more specific. Earth itself will be just fine, but significant portions of the human population living on Earth won't be due to global warming. I have friends living in Florida and Louisiana who will be under water. I have grandkids who will have to live with weather extend and the massive worldwide economic consequences.
Sabine Hossenfelder's video on fusion suggests the "Q" that is often cited is for the plasma... however, for practical purposes, Qplasma >> Qtotal , yet the Fusion Energy Gain Factor that is often cited (10-20) is Qplasma.
Scientist's way to hide the fact that they are not even close to break-even. They need to disguise the numbers, so that they can keep getting billions of dollars of funding, and still continuously be 30 years away. Heck, 40 years ago they were 20 years away from break-even.
I've been fascinated by fusion technology for many years, but let's be real: we're still more likely to see Half-Life 3 before a fusion reactor on our power grids.
Well, we got a new mainline entry to the Half-Life series already at least. That alone is enough for me to call it the 3rd Half-Life game. Is it Half-Life 3 to everyone? No, but to me it suffices. I'm not confident that Valve will go back to a numerical naming convention for that series anymore, or perhaps any. But I do hope they at least make another non-VR Half-Life game. My laptop reaches 80-85 celsius when playing Deep Rock Galactic on max settings (i7 7700HQ, GTX 1060 6GB, 16GB RAM, SSD main OS + gaming + music production drive), I'd be incredibly concerned for its heat tolerance if I tried to play a high end VR game like Alyx on it, despite it being the bare minimum of compatible with that game. Only VR headset I have is a cheap Chinese smartphone one too haha. I've tried the original Vive once and I loved it. Hoping to one day get the Samsung Odyssey+ if it ever becomes $250-300 again. Or I'll wait for the next Odyssey.
Fusion energy would be a fantastic breakthrough if they can achieve it. Fantastic breakthrough & well done!. One way to boost the energy required to kick off the fusion process could be via "bootstrapping" which is common in electronics which is a process used in many switch-mode power supply sections where a small power supply progressively kicks off bigger power supplies which eventually take over. The same principle could be used to allow a set of renewables to say collectively supply the bootstrap energy needed to kick off the fusion reaction as this way once the fusion energy reaches sufficient temperature it could possibly self sustain & the initial bootstrap energy would only be required to restart the entire process from a maintenance shutdown & inspection
Although there have been 2 fission disasters (and another close call), overall, fission is still substantially safer than fossil fuels on a per kwh basis. Fusion would be safer, but it needs to work first.
@@shadesmarerik4112 - The StormFather would be disappointed in you. Proton fusion done like it is in a star is not possible on earth. We can only build temperature-based fusion, not pressure based fusion, as that requires enough mass to equal a star... which kinda defeats the point of making fusion reactors small enough to fit on the earth. The temperature in the core of the sun is about 15 million K, whereas in a reactor like ITER or JET, the temperatures are over 100 million K. The key difference is pressure. In the dense core of the Sun, pressure is at about 265 billion bar of pressure, whereas our earth reactors reach 3-10 bar of pressure. The Sun isn't a proof of concept for anything we could remotely replicate. The 15 million K of the sun isn't enough to make Hydrogen fuse. The density and pressure is what makes solar fusion capable of overcoming the strong nuclear force to fuse atoms.
Has there been some experimentation with scalability? what if 100 tiny reactors could achieve higher efficiency? it looks like all the projects are hugenormous, with fusion we can start smaller...
Fusion is awesome and has the potential to even decrease energy costs further, since fuel is virtually unlimited. If we also manage to increase construction automation, we could see many small scale fusion plants pop up for local communities. Although with that said, I think nuclear fission is still our current best bet, with wind and solar supplementation especially for off-grid folks.
I'd argue similar but kind of opposite: Renewables for main-stay energy and Fission as a backup to make sure that even in changing climate conditions we have sufficient power.
It's definitely promising. I still think we should keep an eye on SMR's, and even consider building more CANDU reactors. It doesn't hurt to have lots of low carbon options in our tool kit, and even old-school nuclear waste is much easier to keep a handle on than hundreds of millions of tons of CO2.
We can build SMRs now. But we need a mass-production factory somewhere. The anglo nations should fund a factory in South Korea. That nation has the industrial capacity and science-aware population needed to make such an enterprise work. (Politics make just a project impossible in any Anglo nation. But the SMR technology will soon be essential.) South Korea can become the free world's provider of SMR. China has a large enough internal market to justify its own factory and might have sufficient over-capacity to provide SMR's to their fellow anti-democratic nations of the world.
I absolutely love the idea of SMRs. I think we should be putting much more focus on them. They have the efficiency of nuclear power, but are more portable and can be grouped together for larger grid networks without all the concrete associated with more traditional nuclear power plants.
@@richardgreen7225 problem is that even if they were being built on South Korea where policies are more relaxed, their use would still be governed by American policies if we are using them in America. Modern policies for Nuclear in general are quite outdated in America in comparison to France and several other countries which are using Nuclear power. We need to address technological advancement while updating Nuclear policy. The IAEA is also really strict in consideration to what every country can do regarding nuclear power and devices. They would also be involved in approving what types of devices South Korea could build legally. Things are complicated because of the potential for hazards to occur if proper protocols aren't in place to ensure high levels of safety.
Unfortunately the term SMR is being used to push repackage submarine reactors, most of them still have the dangerous combination of uranium and water with an efficiency rating 1% and 10,000 to 20,000 years of hazardous storage containment. They are purposely ignoring advancements in nuclear fission over the last 50 years, the few uranium SMR that are free of water and have higher efficiencies are still not very deployable because of the need of security, this leaves only one SMR reactor that makes any kind of since Thorium Molten Salt Reactor, if you're mean a Thorium SMR then I totally agree with you.
@@drmosfet For 70 years, scientists have been unable to make a thermonuclear reactor. why? The answer is simple - wrong theory! The reactor is therefore not done correctly.

Sounds like a promising discovery, and it would be nice to see more advancements like this. Our energy demands only keep growing, and unfortunately, traditional power generation cannot meet these needs in a sustainable manner.
@@Ahamad6011 there is plenty of diversity in the energy space. fussion is THE big boy space. there is not enough investor interest/cash or manpower on the planet to fund so many of these projects at the same time. although, soon as they have another big breakthrough, cash might start flowing real quick.
@Cowboy Ninja Fission kinda is a joke, yeah… because it leaves us with toxic waste we can’t use for much of anything, and there’s been cases of irradiated water and wildlife. Although, there’s speculation that you could actually reuse toxic waste as fusion fuel.
@@JackFoxtrotEDM There are several industry processes that produce much more waste that will be extremely toxic for all eternity, but it only seems to be a problem for nuclear energy for some reason. Fusion is the holy grail, but fission is seriously dope. Producing the energy needs for of an energy hungry westerner and the corresponding waste fits in a small soda can, with the only emissions being the ones that happen during construction is absolutely amazing. Sweden and France all but eliminated the CO2 emissions from their electrical grids within a decade in the 70s by going nuclear, it's absolute one of the answers for climate change until fusion is here for real.
In the meantime, molten salt reactors, which by definition cannot melt down, need to be commercialised. Thorium MSRs have significant potential benefits including far more plentiful fuel than uranium fuelled reactors (without the need for enrichment), and minimal proliferation issues. Waste burner MSRs have the potential to transform the waste from existing solid fuel reactors and decommissioned warheads into considerable energy while producing waste with half lives under 250 years. Morally, we should be building these to transform the existing nuclear waste. Once waste burners become a commercially proven technology, it may even become possible to create a mobile continuous extraction system that could collect waste from former nuclear test sites and accident sites, separate the radioactive compounds and feed them through a waste burner that would power the separation process. Imagine being able to clean up places such as the Marshall Islands.
Unlike fusion, there has been an MSR operating successfully in the past, and the new ones under construction at the moment (eg the one being built in China) or in planning are based on the proven technology from the Oak Ridge MSR.
@@atholmullen Oak Ridge was an experimental prototype, so is the one currently under construction in China. Even if all the problems with the corrosive salt containment were solved (e.g. inter-granular cracks in all metal components), we're still looking at a minimum of 20 years before any significant amount of energy is produced by this type of reactor. And this is a very optimistic estimation.
Great info. Been following the development via Google news on my phone, but this video really puts things into a better perspective. Exactly the kind of story I was looking for. Keep it up!
Aside from the unnecessary demonization of fission energy, this is an excelent video. It's specially satisfying to see mainstream youtubers to factor into the equation the net electricity gain factor, which is something that has been keep under the curtains and created a lot of misinformation in the breakthroughs of fusion reactors.
The world has to demonizes fission or they would not get all the ice melted and that is the agenda,they want the perma frost melted Europe wants palm trees and no Arctic just blue water.
Honestly - I think we're still 30 years out, but this is such great news I only want to laud these scientists and appreciate the sheer scale and scope of what they're attempting. 👏👏👏👏 Ultimately some super-clever people will crack this problem, and then how long it took will be a mere footnote. Fascinating how a 1980s development has kicked on this project close to 40 years later. This is how science builds. For the energy security of the world, I hope it is ready in 30 years. That'll still be utterly amazing.
good to see, 'alternative energy', namely wind-turbines has matured as an industry...but, there's still more that can be done. for example, making the wind turbine blades out of recyclable plastic that floats on water; either PETE or polypropylene, reinforced with glass yarn - fiberglass. centrifugal molding, hand-held extruders for repairing. on top of that all, i'd like to see pneumatic wind turbines, with onshore electricity generation - reducing costs further...
This HTS development would also work well with the Stellerator design, which has a lower energy-in than the Tokamak. Would really like to see that synthesis occur.
I suspect that they will likely run the test using the Tokamak, but, if successful, look into other designs to see if more energy can squeezed out. Likely it will be done as a side project while getting a working long term reactor running so that they can claim that title.
I am one of those people who have followed news about Fusion for the last 10 years at least and yes it's always the same, at least 30 years away. While this does look incredibly promising I won't hold my breath.
You are not following very closely if you think that. There are now at least two companies that are likely to get to positive Q in more like 5 years than 30. (Tokamak Energy and CFS). It'll still be a while till a commercial power plant - perhaps that's what you meant?
Though before then modular thorium reactors would be a good place to go for replacing uranium enrichment based reactors for switching to renewables and phasing out fossil fuels. I agree, don’t hold your breath, but don’t give up hope either.
@@xxwookey No, those will achieve positive Qplasma numbers but not QTotal, in other words they use misleading numbers, it's not the fusion that's going to solve our energy problems. More on that here: ruclips.net/video/RQv5CVELG3U/видео.html
Wait, so as of right now, after 50 years of development, we only have a Q ratio of 0.7. But in the next 3 years, we'll have a ratio of 10.0+? How? That's virtually the whole thing mastered at that point, having been miles off 3 years prior
I see you're not oriented. Q = 8 realized work. China immediately entered the technology. Henceforth it is called the quantum dragon project. New patents registered for Chinese government. The scandal broke out. ruclips.net/video/CZJwwMGTPSw/видео.html
I did a report on ITER in middle school (I wanted to do a report on engines from Star Trek, and this was the thing that my teacher would accept). I'm glad I did because it gives me a sense of perspective on the timelines. (This was just before ITER construction began).
I was thinking about Star Trek while watching this. They use magnetic containment fields to push the antimatter into the reaction chamber, and to contain the reaction inside of the warp core.
@@firstnamelastname2552 Yep! Plus they have fusion reactors to power impulse engines. I've gotta say, my friend who heard I wanted to do a report on something from Star Trek was very disappointed when she couldn't do a similarly themed one on Harry Potter xD
Thorium reactors are far safer than heavy water Uranium reactors and much less energy demanding than Fusion reactors. Even so, this report is very interesting. So many advances in contributing tech that will benefit a lot of other technologies.
Much like a match stick achieves very high localised tempretures to spark a chain reaction. Smaller powercell will work best to indepandantly power devices outside grid supply.
I remember seeing a youtube video with this amazing breakthrough with high-temperature semiconductor COTS tape 7 years ago and a prof from MIT at the time was saying it would only be 5 years away. Now that same team is saying the next step is 4 years away, and that step isn't a working commercial unit? Sound like they'll need time to design and build the full commercial unit, and maybe that'll take the same 10 years the experimental one did? And that gets us to our "20 years away", which I think is the joke, not 30. I'm beginning to think these physics profs have learned how to dangle impossible goals in front of people for funding.
The point is you will still make discoveries among the way that could in turn improve things for mankind. Alot of important and useful discoveries where done by accident or unintended, we later found good use for them. As long as we ARE making progress of somekind thats good for humanity. The real issue would be if we did all that an nothing came out of it THEN you might have a point.
I think that a current, generation 4, Thorium Reactor solves the issues found in the typical gen-2 reactors, that everyone is aware of. That's right, those Nuclear Plants that everyone thinks of, when talking about Nuclear Reactors, everyone thinks about a 60 year old, antiquated technology.
If you do another video on nuclear in the future, it would be good of you to specify that you're specifically referring to Light Water Reactors when you're talking about fission. A lot of work is being done into making better, safer fission technologies, and they shouldn't be discounted; especially the promise held in LFTRs and TWRs.
I’m just happy that my methane reactor works to power my farm. My animals generate the power that caring for them uses…if every farm did this across America we could reduce green house gases by 70% over current farm contributions of greenhouse gases….WHICH ARE NEARLY NOTHING COMPARED TO A NATURAL GAS POWER PLANTS!
Methane emissions, especially from livestock, are major contributors to climate change because methane has a much worse greenhouse effect than CO2. This is why red meat is bad for the environment
Sounds good, but... I'd be interested as to your tillage, seeding, harvesting and trucking power requirements.

Fusion will not work. We are not even sure it is the driving force inside a star. However, we are so sure that we can replicate it here on Earth. If even 1/10th of the resources spent on fusion had been spent on Thorium Molten Salt Reactors we might be mining the asteroid belt already AND actually be 30 years away from fusion.

That was discovered in 1989 (Ponds and Fleischmann). Just a few years ago NASA published research on the exact same phenomenon and all but called it Cold Fusion.
I really don't see you why we're trying to create fusion reactors on earth when we have a huge fusion reactor right next door. Why not just find a way to collect more of the sun's energy from orbit? with the amount of money that's been spent on this pipe dream we could have created a way to collect more of the sun's energy by now
Breeding lithium into tritium is a huge hurdle that may turn out to be impossible at a rate that can compensate tritium losses. This isn't even being addressed by the current fusion research such as ITER. It was glossed over by the expert in this video
Joking aside, this game-changing breakthrough potentially brings nuclear fusion forward from 30 years away to as little as three decades away.

@Peter Evans man, solar isn't happening on an industry and city level. its but a excuse for gas industry to remain relevant... don't Believe me, just look at the difference between Germany (pro-renewables) and France (pro-nuclear).
Thanks for the great news. My Dad was an engineer at the Plasma Physics Lab at Princeton University. They built several fusion reactors as I was growing up starting with the C Stellerator and ending up with a Tocamac. The Tocamac reached what was called break even back then in about 1979. The the lab was a joint venture with Princeton, DOE and Westinghouse as I remember. When Three Mile Island melted down the funding for the lab started drying up. The supper conducting materials and the ability to create better vacuum in the chamber were the big obstacles at that point. It is great to hear MIT is making progress on the magnets. Maybe with RUclips’s like this we can have a better public understanding of the difference between fusion and fission. If the fusion work at the Plasma Physics lab had continued there would be fusion generators producing carbon free electricity right now! That was about 30 years ago. Keep up the good work! John Joyce
If...pigs had wings.
I've never been one of the cynics, mainly because I understand how important materials development is in a bigger project like this, and that we're making breakthroughs almost every month in one way or another. As this story shows, something created in the 1980s is now being used in a new way thanks to developments in application and manufacturing. It takes a million small discoveries to reach a major breakthrough.
I'm convinced we'll get there.
Right,but the main breakthrough is the ReBCO SC tape.Power scales to the third ppowernof the magnet field strength, so twice as powerful 16 times the power.

I tend to be of this mindset: As long as a scientific field sees regular improvement that corresponds with theoretical goals, then I am optimistic. If a field sees significant stagnation for long periods of time, then there is cause for concern.
Any scientific innovation will be "always 30 years ahead" until it one day finally exists and functions as intended. That's just the nature of working with unpaved paths and no known variables to adhere to. In reality, no one knows when we will see commercial fusion reaction - but we see regular exponential improvement and that is a damn good sign. And don't forget, that along the way, all this research will also trickle down into other fields that find use in the same research and proofs of concept - just see how much technology developed for Aviation and Space exploration has found their way into our daily lives through totally unrelated contexts. Innovation is never wasted, no matter the field.

Old enough to remember back when "fusion reactions" were mostly wildly complex formulas on a professor's blackboard. You can tell it's getting more real now that the story is shifting from large, expensive, multi-national experimental concept reactors to an actual startup developing a more practical design. The recent breakthrough was a big step in that direction, but it's going to take several more big steps like that to shed the "30 years away" label.
Well, fusion reactions were considered possible decades upon decades ago. The problem was getting tech/materials/etc. to where a first step into it properly to persue this stuff. Every scientist back in the day with funding could have easily created the reaction...but time always comes later...so it didnt happen...pretty simple and no world bending news that it is now and not 50 years ago...
We have nothing of interest to persue and money extracted out of other humans somewhere else, so that we can now finance our stuff. 😋
Same
The issue was harebrained over-excitable types selling it before it was ready even for solid research. It isn't at all late really compared to other power sources if it comes in the next 25-50 years, it'd still be faster than solar ha
If in fact, we had really widespread adoption of fusion energy within 30 years, that would be great. That assumes that we have practical reactor designs within 10 or 15 years. I am assuming these things take a few years to build at the very least. Not only that, but the infrastructure needs to be built up for extracting D2 from seawater in high quantity. In order to build out enough fusion power plants to supply most of our energy will require hundreds of billions just for the cost of the power plants. I think all these things should and will be done, but expectations that we will have a demonstrated working and efficient fusion reactor today and a transformation of our global energy grid tomorrow are just unrealistic. It will take at least 20 years to build out enough power plants for the US.
Meanwhile China, India, the Netherlands and Norway are building Thorium Reactors now

When I was a kid in the 90's teachers joked that fusion was always 50 years away, so we're making _some_ progress
In the 90's it was 50 years away.. Now it's been 30 years, and we are 20 years away according to most people... Hmm, maybe we actually got it right with the timing 😂? So, 2040 it is

We were down to always 20 years away a few years ago so there have been some setbacks
Just wait a little longer, maybe in 2050 it will be only 10 years away.
I am very happy you are being honest about Q and the actual efficiency of the whole facility.
I hadn't heard/thought of that before!
From the first fusion devices up until 2000 fusion gains were doubling every two years - then we hit a wall
The SPARC magnets should put out a Q of 10, over ten times the point where we stopped. Being built in 2025 that means we are potentially increasing at the speed of Moore's Law again. One or two such jumps beyond SPARC would be the starting point of commercial potential technology
Maybe even one half step. For instance ITER's whole facility efficiency is about break even. The pilot power plant based on ITER would use about 50% more input energy and put out 1000% more power. There may be a similar jump from SPARC to ARC which they hope to build before ITER begins deuterium - tritium plasmas in 2035
Kind of tired about clicking on fusion thumbnails that offer nothing real
@@MichaelHayesagent The optimistic view is that a positive total power balance will be demonstrated in 5 - 10 years. Then another 5 - 10 years for a potentially commercially competitive pilot plant. That's the big if - it should be possible to build a plant putting out net electricity on a commercial scale but there will be engineering and economic hurdles due especially to the super energetic neutrons damaging the plants. There is a new neutron shielding tech being tested by Tokamak Energy next year. Basically I expect a commercial level of power output to be achieved by 2035 - 2040 but I wouldn't be as happy to bet on a commercially competitive fusion design to come out in that time

There was no out-of-control chain reaction at Fukushima, the reactor was completely shut down in time, there was not enough cooling for the short lived decay products due to collapse of surrounding infrastructure and bad placement of backup generators
It was a steam explosion and not a chain reaction as many in the media portrayed it.
And complete flooding of generators and backup batteries caused by bad/dangerous design. Coupled with a complete lack of safety procedures it was only a matter of time.
Chernobyl was also an easily avoidable accident. If all fusion effort and investment had gone into fission, we'd be at least 30 yrs ahead.

2) ITER are also going to try out Lithium Blankets around the chamber to make new tritium fuel to feed back into the process.
So the second ship didn't stop and pick up the old ship? Man, they are some real assholes!
how ironic, funny too LOL
I love how as advanced nuclear energy is, it's basically just a steam engine with extra steps.
Everything is steam engines coal and gas plants all create steam pressure to spin turbines. Water is abundant
Yeah it is quite extraordinary that after all these decades, nobody has been able to come up with a better way of converting heat energy into electricity. If someone was to come up with a more efficient way of doing that large scale, that would be an incredible breakthrough.
It’s horribly inefficient too.
Some advanced reactors were made to use gas turbines which are not so new discovery. Molten salt reactors are so energy dense it doesn't really matter if they use steam turbines because they are much better at harvesting energy from the fuel.
Ironically, the nuclear part is what holds the highly advanced steam technology back in that case. The greater the difference between the hot and cold side of a heat engine, the greater the efficiency. Coal plants have all moved to supercritical steam (i.e. hotter steam) whereas nuclear reactors remain constrained by the cores to much lower and therefore less efficient steam temperatures.
A 20 tesla HTS magnet is a game-changer by itself - This would mean we can put high-resolution MRI machine in every large hospital, fusion or not.
A lack of citations and tech. publications around this 20T magnet is a bit disconcerting, though. Why the cloak-and-dagger? Where is the opportunity for someone else to replicate their experiments with a commercial REBCO tape to build a 20T magnet and conform their findings?
Their "High temperature superconductor" also seems to be a misnomer. Traditionally, Y1Ba2Cu3O7 (YBCO) superconductors are considered "high" temperature because you can use (relatively cheap) liquid nitrogen (LN) to get them superconducting. These are unfortunately not able to withstand the typical 6T - 12T magnetic flux density inside a typical MRI-bore; a liquid-helium cooled "low-temperature" superconductor is traditionally essential for this task (and also for the LHC at CERN and for other facilities).
If someone claims "20T HTS" - I would interpret this as "a superconductor that can be realized with liquid nitrogen, capable of producing 20T". This is not the case. The REBCO material here needs -254'C instead of -269'C (i.e.. 19K instead of 4K) . This is a big achievement, sure, but not quite "HTS".
There goes the LN-cooled-MRI out of the window :( .. for now.

Matt, I was a nuc in the Navy in the 70's and we talked a lot about fusion in school (which was over a year long). We all thought Fusion would be a reality by 2000 but seemed to fade from the discussion over time. It is very heartening to hear that such progress is finally being made and Fusion might actually be a reality. If it is, we will solve the worlds carbon problems and provide power for a world hungry for it. Love your videos!
Fusion funding is consistently cut in half, doubling the time needed. This breakthrough for this is piggybacking on a breakthrough from the 1980s? Imagine if we had the funding to put more brains on this 40 years ago. Would this breakthrough have happened in the '90s? or still take 40 years?
Imagine the Nuclear power if the Manhattan Project was given a continuously shrinking budget every time they had a breakthrough. Look at how long it took Iran, Pakistan, India, North Korea et al to figure it out with lower budgets.

3:16 "causing a nuclear meltdown or explosion". Worth pointing out that the explosion is not like a nuclear fission bomb, it's more like a conventional explosive, admittedly one that can easily scatter radioactive material all over the local area, or toss it into the atmosphere.
Causing an actual nuclear explosion takes very specific conditions like highly enriched uranium or plutonium and large amounts of implosive force.
In short, a dirty bomb instead of a nuclear one.
And there's plenty of catastrophic failure modes in a fusion reactor as well. Quenching of the superconductors, implosion of the vacuum vessel, failure in the power electronics that drive it... those will all result in a 'significant boom' kind of scenario. Although the chance of it releasing radioactive isotopes is a lot less - the hazards are much more local.
@@Stoney3K Not really. There is no "significant boom" in a fusion reactor accident.
Remember, a fision reaction is happening naturally in enriched fissile material of critical mass. The job of a nuclear reactor is to manage that reaction and keep it from turning uncontrollable. If significant parts fail, you loose control.
A fusion reaction, requiring extremely high temperatures and pressures, does not happen unless it is forced to happen.
And the whole setup of a fusion reactor is designed to force it.
If any significant part of it fails, that just means the fusion reaction will just fizzle out.
Remember fusion only happens if you heat a gas to the point of being a plasma, and then magnetically compress it into fusing.
If it drops below the temperatures needed for plasma, then it losses it's magnetic characteristics and expands, and if some part of the magnetic system fails, it expands as well, cutting out the fusion process.
While that's true, apparently in the Chernobyl incident it's been hypothesised that a small section of the reactor did actually have the neutron environment necessary to go prompt critical.

I wonder if a smaller reactor like this would be good for running colonies on the moon or mars. They need both the heat and the electricity.
there's never going to be a better fusion reactor than the Sun. And it's already putting out all the energy we need to populate the solar system and explore neighboring stars. We need nothing else. Not in space, and not here on the ground. The Sun does everything any species could need to leave the solar system.
These technologies aren't about need, they are about consolidation and control. You can own the fuel, and the machines, and the debts of workers. You can't own sunshine. But it does provide free energy everywhere in all directions. All we need is a way to capture it and use it efficiently.
Concentrating it should be left to the R&D budgets of the massive corporations trying to capitalize on concentrated deployment.

These can be made safe and small enough so that small communities can have their own reactors and protect the possibility of blackouts due to one or two reactors going off-line for whatever reason. The smaller Thorium Molten Salt nuclear reactors will be able to generally take up the slack. After watching the entire video on this new breakthrough in a smaller and equally powerful magnetic containment field I am more hopeful for nuclear fusion that I was earlier. I still think we need to still go forward with Thorium Molten Salt nuclear fission reactors.
Um the US government made an Integral Fast Reactor that is unable to reach melting point. So we should do more research on the IFR design than ordinary Molten Salt Reactors.
Yep.
Safety is not the big issue with nuclear reactors - COST is. It's an expensive way to boil water. Why would either thorium or fusion, be cheaper? Proven and relatively unsophisticated reactor designs simply cannot compete economically with other renewables, why would completely novel cutting edge designs?
@@kenoliver8913 *Small Modular Reactor* designs essentially eliminate the COST argument against nuclear. COST being an artificial constraint anyway, easily addressed if humanity were to unite around nuclear energy.

I've been fortunate enough to be very close to what I call "big science'" my entire career, the publicly funded fusion experimental machines MFTF for a few years, the SLAC upgrade from LINAC to rings, then the National Ignition Facility from design through commissioning, and into operations. Noteworthy physics and engineering breakthroughs aside, the big question for me is this: Will private investors maintain the motivation and 'have the stomach' to forge past the latest challenges, will project leadership be able to constantly 'sell it' to keep funding pouring in? If not, then the technology isn't quite ready for this next privately funded phase.
Will private investors maintain motivation...it would be so amazing to change the mainstream narrative about the future. The scarcity story about overpopulation and doomsday global warming, that we have imo very little control over, what if it flipped into a "wow, look at this frontier we can take part in" kind of story? Mainstream, regular people are considered too shallow and dumb. But honestly I'm a hairdresser, not especially smart or educated- and I'm like...i love this story and I want to invest in it. It has quality. Do you think with the powers of media that are currently terrifying everyone, telling us humans are certainly a cancer, and we will die in a fiery inferno- this weird heard it before religious pattern - what if that power of media became captivated with this story, inviting crowd source type money to the new energy sources. I know that's not enough money even en masse, but just dreaming of the post scarcity world we can make together, if the story patterning of guilt and shame for existing somehow shifted to telling stories like this one broadly and with gusto.

So fusion is only '5 years away' now, we're getting asymptotically closer 🙂
If they're projecting that this reactor will be built by 2025... If I know anything about research projects, it's that it won't be built by 2025. That's a _long_ time to last without losing funding. And whenever they do build it, the heat containment issues will take years to solve at best. So realistically this thing is ten years away. And that's _if it works._
I wish more could be said about molten salt fission reactors. They don’t have of the safety detriments spoken of herein, don’t take large plots of land, don’t require access to water source, and are over hundred times more efficient than existing fusion reactors (light water). Experimental reactors like this were already made in the 60’s and 70’s. They don’t need a huge energy kickstart like fusion, and they don’t mess around with the meaning of Q factors like fusion always does (Q is never just energy in over electricity out, which is what it should be).
true, though i def feel we will probably discover the magnetic field issue with fusion reactors far before we figure out the Corrosive issue with MSFR's....but shit at this point who knows.
@@JustinKrux the corrosion and tritium issues have been solved (Hastelloy-N and supercritical CO2 turbine generator). I guess my point is, if a fraction of the money spent on fusion had been spent of MSRs, the West would already have them in the field. As it is, China is the only one who has one.
Tony Hill (Former director of INL {Idaho National Laboratory} ) is currently on this exact mission; head to head battle with Bill Gates....Gates is pushing hard for thorium salt reactors.
@@randalljsilva Interesting!
@@randalljsilva I thought Hestelloy-N was not yet the answer? My current understanding of the issue is that neutrons bombarding the nickel. The nickel would then go through Alpha decay and those helium atoms would lodge in the grain structure. This would then make the material become very brittle over time leading to cracks and leaks in major structural components.
This video gives me hope that fusion is only 29 years away.
28.5 at most.
Kindda optimistic now are you?
I remember when it was a whole 20 away a decade ago.
It seems pretty game-changing as far as field strength, but plasma stability is still a major concern. Moreover, the stronger the field/confinement, the more difficult it is to maintain stability.
i remember watching a show called 21 up that followed a group of people through their lives every 7 years and one of them at 21 was working on a fusion reactor and was optimistic that they would figure it out within a few years (this was in the 80's). A few decades later he was a math teacher and said he would be surprised if it could be figured out any sooner than 100 years
it's a big part of why I don't begrudge fusion researchers always being 30 years away from a working prototype - we're the equivalent of renaissance-era scientists knowing the semiconductor transistors are possible, but not knowing exactly how to make them, and using all of our pre-industrial ingenuity to figure it out from scratch.
@@ecyor0 Renaissance-era scientists that understood electrical conductivity? As recently as the beginning of the 20th century, our most inspired electrical scientists, Tesla included, believed the earth and sky made good conductors...

Agreement that we cannot use them on current level, for the sake of humanity and planet, is what is driving current change.

Great show
The "smartphone" (exemplified by the 2007 iPhone) was the confluence of a powerful, energy efficient chip plus better battery plus better screen plus better network speed. Same may happen with fusion, you just need to be able to make all the parts to drop into place.
When railroading time comes you can railroad - but not before. R. Heinlein. The Door Into Summer.
Also, once that net power gain goal has been achieved, the focus can shift to scaling up and increasing efficiency, while automating production.
The first car wasn't built on Henry Ford's assembly line either.
Will it the size of a phone?
The initial iphone was worse than other smartphones at the time. The only thing it had going for it was Apple marketing and a more user friendly interface. technology wise it was behind. It took many iterations of the iphone before it caught up in tech to the other phones on the market. If I remember correctly the 5 was the first one that was caught up. When they were up to the 4, they still didnt understand how to build antennas even, which resulted in Steve Jobs actually telling someone they were holding their phone wrong... since if you held the phone in specific ways(which were normal ways of holding a phone, just not the way steve jobs held a phone) it disrupted the antenna
Another aspect of what youre saying is that we had the technology to build an iphone in 1980 but it would have cost billions of dollars. So the only thing you can do is wait.
I have seen so many "breaktroughs" since I became interested in fusion that I do not get excited anymore. Just another piece of the puzzle.
The power of a reactor scales to the third power of the magnetic fields these magnets being the same side but provide 10X the power,I can see why you would not think it important, you must follow the science closely.
@@paulbedichek2679 It doesnt solve the problem of the blanket, or the problem of how to get tritium without needing immense amounts of lithium, and so on.
Its a piece of the puzzle. And its useful in other fields of science. Thats it. Doesnt mean nuclear fusion will be "ready" in time to prevent climate change, still way off that target.
So, yeah, its good progress, but nothing to get hyped about.
"Just another"? Why so dismissive? Every piece is just another until you get to the last one that joins them into a whole. The problem is that often the developer of the last piece gets the whole of the credit. In reality, every piece counts and contributes, and often not to just one type of problem.
It does remind me about the constant streams of news we had about quantum computers back in 2011/2012
Doesn’t mean it’s not a major stepping stone
Thanks for the update on this effort. Over 35 years ago I had the opportunity to join a SDSU field trip to visit the tokamak experiment at General Atomic in San Diego. I was thoroughly blown away, and hopeful for this technology to advance. I’m happy to hear that major strides are being made, and I await my Mr. Fusion powered Back to the Future DeLorean someday soon…

Played some game years ago that was about managing a nuclear fission reactor, and it turned out to be fairly realistic. Dunno why, but it made something click in my brain, and I realized I actually really enjoy learning and teaching people about them. Nuclear fission/fusion reactors are just weirdly badass. If it weren't for Chernobyl, I think we'd have quite a few more people cheering it on.

What about Fukushima?
Fukushima if you examine it was actually a success story. An old design survived the 4th most powerful earthquake on record and the resulting tsunami with only causing one direct death and far less environmental damage than standard coal plant operation, let alone when one of those goes tits up.

This talk of fusion reactors misses some key issues:
1- How to continually extract helium out the plasma and keep optimal ratios of deuterium and tritium.
2- How to transfer excess of heat generated in a safe way to another fluid so to generate steam for turbines to move electrical generators.
3- Find a different way to generate electricity from plasma without using thermal cycles to produce work.
1.Yes, breeding tritium in practice is an unsolved and rarely mentioned problem.
2. Yes, while running superconductors in the same room.
3. Good luck with that!
Missing the v point you are converting to heat energy to do work. The amount of work from any heat engine is related to difference of temperature in the hot and cold wells, that's why power plants have cooling towers
On #3, if part of the process of fusion is stripping electrons away from deuterium/tritium to create helium shouldn't there be a time interval between stripping the electrons away to produce the ionizing plasma and the 'reconstitution' phase creating helium, wherein the temporarily freed electrons could be used to induce an alternating current directly into a motor/turbine? No need for steam?
@@pierrechildress8875 that probably only will be able to recoup partially the energy that was required to get the initial gas into a plasma. Not the energy necessary to heat and pressure the plasma into the the conditions necessary for nuclear fusion. Also most of the energy will be in the form of heat, and for helium ions charge neutralization there is the need to spend energy in separating from the plasma. And even with their charge in neutral most of the energy is still in the form of heat. And at this stage you will need to rely on thermal cycles, and that means that for fusion reactors the Q number needs to be very high as to overcome all the inefficiencies that will occur in the process of generating electricity.
Magnetic biomechanical fly- wheel core. Cold liquid electromagneified liquid gas to cool the walls of the reactor and feed the reaction. Acoustic magnogravitational outer mechanics to keep the reaction stable and compressed or kept in uniform
for those interested: there is a correlation on how hot the plasma needs to be vs how strong the magnetic field is. Plus there is also an interesting proposal on using liquid surfaces for plasma-facing components. And I agree - must suck for iter folks to work on something that is going to be hopelessly outdated by the time they are done
Correct. ITER is a joke and frankly should be disbanded entirely. It’s the completely wrong direction for fusion now that we have REBCO superconductors.
There's a ton of research going on with ITER that goes beyond just a "proof of concept" for a net energy production fusion reactor. We just don't know how these materials change over long time periods (greater than fractions of a second) of operation.
Did not expect any news this year, given ITER's continuous delays. That's pretty exciting. Can't wait to read up on the details.
It's even better that there are good news, since ITER has also finally stopped being so mismanaged at long last.
No one is counting on ITER.
@@paulbedichek2679 ITER has a bad rep. but I think it's essential to consider it is not only a facility for achieving fusion. It's an experiment where all kinds of fusion related technology will be explored.
As far as I know, ITER's big contribution may be in things like shielding materials capable of withstanding the high ammount of neutron radiation, knowledge about high energy plasmas and confinement, etc. Which probably will help advance other fusion designs.

Several Problems, First the Net Q energy release was only compared to the energy needed for the massive laser or Q Plasma, it did not include the energy required to run the actual reactor (Q Total) which has massive electromagnets and all kind of conduction systems. Also all that was produced was heat, not actual energy, they are extrapolating the heat produced into the electricity it could produce, which is another entire energy requiring process. And also the Tritium is really rare and we do not have quantities at Scale and Scope and to manufacture Tritium requires enriched Lithium-6, not a fun substance to have around. The ITER Reactor experiment will use half of the Tritium on earth by itself. This is all Hopium Squared.
The quiet part nobody says out loud is that fusion isn't really clean. Fusion creates tons of gamma rays and high energy neutrons (actually much more than fission reactors). 80% of the fusion reaction's energy is in the form of high energy neutrons that need to be absorbed by something and converted into heat in order to use that energy and whatever materiel is being used to absorb the neutrons will slowly become radioactive over the years by means of neutron activation and will eventually have to be disposed of somehow.
Maybe it's easier for fusion than for fission, choosing some isotopes we can reprocess. Certainly has less nuclear weapons proliferation risk, and the radioactive half-lives can be shorter, and the radioactive concentrations lower. But still a bit dirty inside the recycling loop.
Great update Matt. As for fusion, I have a bottle of wine set aside for the day fusion energy is harnessed for commercial use. Thankfully, it gets better with age and hope to drink it in my lifetime.

As an apprentice engineer around 1971 I was shown a newspaper headline on a fantastic new line of research “Fusion Tokamak” and a major breakthrough that could supply free energy for all.
I’ve now retired 50 years later, STILL WAITING. I’d like to say I’ll believe it when I see it but now at 66 years old another 30 years away seems unlikely.
I remember being about 7 or 8 y.o. and people were talking about it. Now I'm 44, and I figure I'm gonna croak first. On the other hand, we're seeing some electric vehicles now, and even if they aren't cost-effective yet they're certainly very energy-efficient.
People said that about flying heaveir than air machines. It will happen. Just not as fast you would like.

It Can still happen just one lucky breakthrough.
The Tokamak reactor design should have been dropped ages ago.
I learned the word Tokamak from an encyclopedia my parents gave me as a lad around 1963. I thought I was up with the latest research. Still waiting.
From what I have read, it isn't true that fusion reactors wouldn't have a nuclear waste problem. The reactors and blanket materials will become highly radioactive over time and then there is the waste from the fission nuclear reactors which are required to make the tritium component of the fuel. No free lunch and it's more than 30 years away seemingly.
“The power of the sun in the palm of my hand” - -Doc Ock
I think it doesn't matter if "fusion is always 30 years away". Fusion *is* the ideal energy source, the proof that it is only an engineering challenge, not a physics challenge, is literally in the stars, and so we simply have to keep trying to solve the engineering challenge. And we are. So bring on the jokes, and bring on the fusion power plants. They will change the world like nothing has ever done before.
That's what I always keep thinking about. I mean we literally did achieve fusion many times already, so we can kinda say we did " It " already. Only problem is making it more efficient, but a few years ago I thought fusion was impossible unless it is in a star, and yet here we are, not trying to create it ; but just make it more efficient
One issue is that a star is a truly awful fusion plant, it takes 5 billion years to burn a small fraction of its fuel, and it is huge. The problem we have is that we need a much much better power plant than this, which isn't automatically possible, though it is looking like it is
@@daveansell1970 I'm not an expert but how is it awful that it takes 5 billion years? The energy released by the sun in 1 fraction of a second is still way enough to sustain Earth (if we could harness it of course)
Energy transport over long distance could be a key too. After all we already have an 100% efficient fusion plant in the middle of the solar system. I wonder how much would have been achieved on the subject with the same fundings.
its dirty just as bad as fusion from all the radioactive waste products.
"MIT and CFS are now aiming for the stars!" Maybe literally. Fusion, if we ever get it going, could be the most reliable source of energy we've ever developed, and could allow us to get back into space.
Utter nonsense. There is no terrestrial source of energy than fission.,

Ah, yes, the fifth November. I know of no reason it should should ever be forgot.
Will the new fusion reactor really be boiling water to make electricity as one commentator pointed out or will it be able to covert the reaction directly into electricity? Converting directly to electricity seems possible since plasma is involved and part of the plasma is made up of electrons freed from the nucleus of basically water atoms.
water.
I was in grad school in the 1970's, when fusion power was 30 - 50 years away. I guess the Tokamak was beginning to emerge as the most likely answer about then.
There was also the Stellarator, and the mirror machine; can't recall whether inertial confinement (implosion of D-T pellets, driven by lots of high-power laser beams) was coming into play at that time or a bit later.
Well, here we are 50 years later, and the Tokamak design still looks like the winner; the others having largely faded away.
At least there are starting to be prospects for success in less than 3 decades.
I'm encouraged by this news; I'm not popping any corks just yet, but this actually could finally turn the corner on this.
There are just so many hurdles still to clear, that it's way too early to go bonkers.

It works great to grow the plants in my yard and it’s free outside.
Why keep demonizing fission?? It's most likely the only real way to reduce carbon emissions from electricity production in a fast, meaningful and reliable way.
Fission deserves much more focus and support to improve it's economical viability. It's benefits far outweighs the risks, which are incredibly small in new gen reactors, and waste is far more manageable than most people think.
Exactly. That is why the BREST 300 is manufactured in Russia. A safe nuclear reactor that uses radioactive waste from today's nuclear power plants as fuel.
Yeah the waste is managable but not only is the fuel limited the waste is basically permanent, it is not a permanent solution to energy think of it like coal, it was insane when it was first discovered but in the end it had to be changed for something better, also fusion in theory can be far more powerful than nuclear, has nigh infinite fuel and has virtually no way of melting down, it also doesn't produce any waste in fact could use nuclear waste as fuel, but I would never demonize them they are incredibly useful and arent even that volatile
@@mareksykora779 Oh shit thats one awesome reactor tho just learning about it
@@MonsterPumpkinHowever, there is still a lot work to be done in the field of nuclear fusion. By the time the experimental fusion reactor continuously produces more electricity than it consumes, many standard nuclear reactors will be built. That is why it makes sense to invest in nuclear waste reactors, just like the BREST 300. We now have a huge amount of such waste.
I'd say it's a game-evolver; just as what happened in aviation, in automotive, in electronics, etc. I believe there is indeed room for enthusiasm but certainly not room enough to fit such dramatic words as game-changer yet ...at least, at this stage.
Great vidéo, subject and research, though. 👍 Cheers
So, basically copper duck tape fixed the whole nuclear fusion problem. Duck tape can fix anything.
No one doubts how great nuclear fusion reactors would be - if we could get them to work. But given the need for clean power now , it would seem that putting money into thorium reactors may be a better solution for the time being.
Maybe the greater current needed is the impetus that will push fusion to the fore. 🤔
It seems we are still well over a decade away from a Q sufficient for meaningful generation. And once we reach that milestone, we still must replace all that entrenched fossil fuel generation, so slap another decade or two on top of that. Regrettably, Earth just can't wait that long.

Fusion energy would be a fantastic breakthrough if they can achieve it.
Fantastic breakthrough & well done!.
One way to boost the energy required to kick off the fusion process could be via "bootstrapping" which is common in electronics which is a process used in many switch-mode power supply sections where a small power supply progressively kicks off bigger power supplies which eventually take over.
The same principle could be used to allow a set of renewables to say collectively supply the bootstrap energy needed to kick off the fusion reaction as this way once the fusion energy reaches sufficient temperature it could possibly self sustain & the initial bootstrap energy would only be required to restart the entire process from a maintenance shutdown & inspection
Although there have been 2 fission disasters (and another close call), overall, fission is still substantially safer than fossil fuels on a per kwh basis. Fusion would be safer, but it needs to work first.

The temperature in the core of the sun is about 15 million K, whereas in a reactor like ITER or JET, the temperatures are over 100 million K.
The key difference is pressure. In the dense core of the Sun, pressure is at about 265 billion bar of pressure, whereas our earth reactors reach 3-10 bar of pressure.
The Sun isn't a proof of concept for anything we could remotely replicate. The 15 million K of the sun isn't enough to make Hydrogen fuse. The density and pressure is what makes solar fusion capable of overcoming the strong nuclear force to fuse atoms.
3, Chernobyl, Fukushima, 3 Mi Island
@@johnthomas2485 3 mi island was a close call. No significant radiation escaped.
Has there been some experimentation with scalability? what if 100 tiny reactors could achieve higher efficiency? it looks like all the projects are hugenormous, with fusion we can start smaller...
Fusion is awesome and has the potential to even decrease energy costs further, since fuel is virtually unlimited. If we also manage to increase construction automation, we could see many small scale fusion plants pop up for local communities.
Although with that said, I think nuclear fission is still our current best bet, with wind and solar supplementation especially for off-grid folks.
I'd argue similar but kind of opposite: Renewables for main-stay energy and Fission as a backup to make sure that even in changing climate conditions we have sufficient power.
Crack fusion and we’ll be all set to wreck the environment in every other way.
Matt - really appreciate your videos, you are a great host / narrator. Keep up the good work.
Thorium Salt Reactors are my favorite alternative, that and fusion
What a toxic mess they are
You seem to become more confident and that makes your videos better. Good on you. Keep up the good work.
It's definitely promising.
I still think we should keep an eye on SMR's, and even consider building more CANDU reactors. It doesn't hurt to have lots of low carbon options in our tool kit, and even old-school nuclear waste is much easier to keep a handle on than hundreds of millions of tons of CO2.
We can build SMRs now. But we need a mass-production factory somewhere. The anglo nations should fund a factory in South Korea. That nation has the industrial capacity and science-aware population needed to make such an enterprise work. (Politics make just a project impossible in any Anglo nation. But the SMR technology will soon be essential.) South Korea can become the free world's provider of SMR. China has a large enough internal market to justify its own factory and might have sufficient over-capacity to provide SMR's to their fellow anti-democratic nations of the world.
I absolutely love the idea of SMRs. I think we should be putting much more focus on them. They have the efficiency of nuclear power, but are more portable and can be grouped together for larger grid networks without all the concrete associated with more traditional nuclear power plants.
@@richardgreen7225 problem is that even if they were being built on South Korea where policies are more relaxed, their use would still be governed by American policies if we are using them in America. Modern policies for Nuclear in general are quite outdated in America in comparison to France and several other countries which are using Nuclear power. We need to address technological advancement while updating Nuclear policy. The IAEA is also really strict in consideration to what every country can do regarding nuclear power and devices. They would also be involved in approving what types of devices South Korea could build legally. Things are complicated because of the potential for hazards to occur if proper protocols aren't in place to ensure high levels of safety.
Unfortunately the term SMR is being used to push repackage submarine reactors, most of them still have the dangerous combination of uranium and water with an efficiency rating 1% and 10,000 to 20,000 years of hazardous storage containment. They are purposely ignoring advancements in nuclear fission over the last 50 years, the few uranium SMR that are free of water and have higher efficiencies are still not very deployable because of the need of security, this leaves only one SMR reactor that makes any kind of since Thorium Molten Salt Reactor, if you're mean a Thorium SMR then I totally agree with you.
@@drmosfet For 70 years, scientists have been unable to make a thermonuclear reactor. why? The answer is simple - wrong theory! The reactor is therefore not done correctly. Scientists do not yet know how to make a thermonuclear reactor that gives out commercial heat. When do scientists promise to make a commercial thermonuclear reactor? Promise in 40 years! And they don't guarantee that. But, there is a technology that will help make a commercial thermonuclear reactor in two years. The theory is correct, the reactor design is correct.. I offer the transfer of technology for free, under the contract. 70 лет учёные не могут сделать термоядерный реактор. Почему? Ответ простой - неправильная теория! Реактор поэтому сделан неправильно.

Sounds like a promising discovery, and it would be nice to see more advancements like this. Our energy demands only keep growing, and unfortunately, traditional power generation cannot meet these needs in a sustainable manner.
It would be nice to see more diversity
@@Ahamad6011 there is plenty of diversity in the energy space. fussion is THE big boy space. there is not enough investor interest/cash or manpower on the planet to fund so many of these projects at the same time. although, soon as they have another big breakthrough, cash might start flowing real quick.
@Cowboy Ninja Fission kinda is a joke, yeah… because it leaves us with toxic waste we can’t use for much of anything, and there’s been cases of irradiated water and wildlife. Although, there’s speculation that you could actually reuse toxic waste as fusion fuel.
ruclips.net/video/hEND8dlUp1Y/видео.html
@@JackFoxtrotEDM There are several industry processes that produce much more waste that will be extremely toxic for all eternity, but it only seems to be a problem for nuclear energy for some reason.
Fusion is the holy grail, but fission is seriously dope. Producing the energy needs for of an energy hungry westerner and the corresponding waste fits in a small soda can, with the only emissions being the ones that happen during construction is absolutely amazing. Sweden and France all but eliminated the CO2 emissions from their electrical grids within a decade in the 70s by going nuclear, it's absolute one of the answers for climate change until fusion is here for real.
In the meantime, molten salt reactors, which by definition cannot melt down, need to be commercialised.
Thorium MSRs have significant potential benefits including far more plentiful fuel than uranium fuelled reactors (without the need for enrichment), and minimal proliferation issues.
Waste burner MSRs have the potential to transform the waste from existing solid fuel reactors and decommissioned warheads into considerable energy while producing waste with half lives under 250 years. Morally, we should be building these to transform the existing nuclear waste.
Once waste burners become a commercially proven technology, it may even become possible to create a mobile continuous extraction system that could collect waste from former nuclear test sites and accident sites, separate the radioactive compounds and feed them through a waste burner that would power the separation process. Imagine being able to clean up places such as the Marshall Islands.
There's not a single operating MSR in the world.
Unlike fusion, there has been an MSR operating successfully in the past, and the new ones under construction at the moment (eg the one being built in China) or in planning are based on the proven technology from the Oak Ridge MSR.
@@atholmullen Oak Ridge was an experimental prototype, so is the one currently under construction in China.
Even if all the problems with the corrosive salt containment were solved (e.g. inter-granular cracks in all metal components), we're still looking at a minimum of 20 years before any significant amount of energy is produced by this type of reactor.
And this is a very optimistic estimation.
Or Hanford or all uraniumrefinig sites
@@wermagst I guess we'll see how well your argument ages. I'm going with not well.
Great info. Been following the development via Google news on my phone, but this video really puts things into a better perspective. Exactly the kind of story I was looking for. Keep it up!
Aside from the unnecessary demonization of fission energy, this is an excelent video. It's specially satisfying to see mainstream youtubers to factor into the equation the net electricity gain factor, which is something that has been keep under the curtains and created a lot of misinformation in the breakthroughs of fusion reactors.
The world has to demonizes fission or they would not get all the ice melted and that is the agenda,they want the perma frost melted Europe wants palm trees and no Arctic just blue water.
"demonization of fission energy" - fission energy is not the problem. The problem are humans who can't manage to build something properly.
Fission energy is only practical if one expects humanity to die off before the waste situation gets completely out of hand.
@@Alltime2050 not true. much safer and less long lasting in quantity than most think. still, fusion is better!
Aside from not understanding why fission energy is a dead end, your comment is correct.
Honestly - I think we're still 30 years out, but this is such great news I only want to laud these scientists and appreciate the sheer scale and scope of what they're attempting. 👏👏👏👏
Ultimately some super-clever people will crack this problem, and then how long it took will be a mere footnote. Fascinating how a 1980s development has kicked on this project close to 40 years later. This is how science builds.
For the energy security of the world, I hope it is ready in 30 years. That'll still be utterly amazing.
"In 30 years, we can expect functioning 30-year jokes."
good to see, 'alternative energy', namely wind-turbines has matured as an industry...but, there's still more that can be done. for example, making the wind turbine blades out of recyclable plastic that floats on water; either PETE or polypropylene, reinforced with glass yarn - fiberglass. centrifugal molding, hand-held extruders for repairing. on top of that all, i'd like to see pneumatic wind turbines, with onshore electricity generation - reducing costs further...
This HTS development would also work well with the Stellerator design, which has a lower energy-in than the Tokamak. Would really like to see that synthesis occur.
I suspect that they will likely run the test using the Tokamak, but, if successful, look into other designs to see if more energy can squeezed out. Likely it will be done as a side project while getting a working long term reactor running so that they can claim that title.
I want to see the REBCO tape applied to the Polywell IEC device
@@Sin526 You just taught me something. Thanks!
I am one of those people who have followed news about Fusion for the last 10 years at least and yes it's always the same, at least 30 years away. While this does look incredibly promising I won't hold my breath.
You are not following very closely if you think that. There are now at least two companies that are likely to get to positive Q in more like 5 years than 30. (Tokamak Energy and CFS). It'll still be a while till a commercial power plant - perhaps that's what you meant?
it used to be always 50 years away until it came down to 30.
Though before then modular thorium reactors would be a good place to go for replacing uranium enrichment based reactors for switching to renewables and phasing out fossil fuels. I agree, don’t hold your breath, but don’t give up hope either.
@@j.f.fisher5318 Yep, that happened about 60 years ago.
@@xxwookey No, those will achieve positive Qplasma numbers but not QTotal, in other words they use misleading numbers, it's not the fusion that's going to solve our energy problems. More on that here: ruclips.net/video/RQv5CVELG3U/видео.html
Dude with a pacemaker standing next to the HTS magnet: 'what's this hole in my chest?'
I have a pacemaker. Also, I'm an electrician. My doctor frowns on that. 😂
waiting for a magnet strong enough to pull the blood from your body with the iron in your hemoglobin. Now thats true power
Wait, so as of right now, after 50 years of development, we only have a Q ratio of 0.7. But in the next 3 years, we'll have a ratio of 10.0+? How? That's virtually the whole thing mastered at that point, having been miles off 3 years prior
I see you're not oriented.
Q = 8 realized work.
China immediately entered the technology.
Henceforth it is called the quantum dragon project.
New patents registered for Chinese government.
The scandal broke out.

I did a report on ITER in middle school (I wanted to do a report on engines from Star Trek, and this was the thing that my teacher would accept). I'm glad I did because it gives me a sense of perspective on the timelines. (This was just before ITER construction began).
I was thinking about Star Trek while watching this. They use magnetic containment fields to push the antimatter into the reaction chamber, and to contain the reaction inside of the warp core.
Yes. What's the holdup on antimatter reactors? Have we not discovered Dilithium yet?
@@firstnamelastname2552 Yep! Plus they have fusion reactors to power impulse engines. I've gotta say, my friend who heard I wanted to do a report on something from Star Trek was very disappointed when she couldn't do a similarly themed one on Harry Potter xD
Thorium reactors are far safer than heavy water Uranium reactors and much less energy demanding than Fusion reactors. Even so, this report is very interesting. So many advances in contributing tech that will benefit a lot of other technologies.
Much like a match stick achieves very high localised tempretures to spark a chain reaction. Smaller powercell will work best to indepandantly power devices outside grid supply.
I remember seeing a youtube video with this amazing breakthrough with high-temperature semiconductor COTS tape 7 years ago and a prof from MIT at the time was saying it would only be 5 years away. Now that same team is saying the next step is 4 years away, and that step isn't a working commercial unit? Sound like they'll need time to design and build the full commercial unit, and maybe that'll take the same 10 years the experimental one did? And that gets us to our "20 years away", which I think is the joke, not 30. I'm beginning to think these physics profs have learned how to dangle impossible goals in front of people for funding.
That is a cynical attitude that says more about your own morals than these scientists.
The point is you will still make discoveries among the way that could in turn improve things for mankind. Alot of important and useful discoveries where done by accident or unintended, we later found good use for them. As long as we ARE making progress of somekind thats good for humanity. The real issue would be if we did all that an nothing came out of it THEN you might have a point.
I think that a current, generation 4, Thorium Reactor solves the issues found in the typical gen-2 reactors, that everyone is aware of.
That's right, those Nuclear Plants that everyone thinks of, when talking about Nuclear Reactors, everyone thinks about a 60 year old, antiquated technology.
If you do another video on nuclear in the future, it would be good of you to specify that you're specifically referring to Light Water Reactors when you're talking about fission. A lot of work is being done into making better, safer fission technologies, and they shouldn't be discounted; especially the promise held in LFTRs and TWRs.
I’m just happy that my methane reactor works to power my farm. My animals generate the power that caring for them uses…if every farm did this across America we could reduce green house gases by 70% over current farm contributions of greenhouse gases….WHICH ARE NEARLY NOTHING COMPARED TO A NATURAL GAS POWER PLANTS!
How do you capture the methane emissions? Do you keep them inside all the time?
Methane emissions, especially from livestock, are major contributors to climate change because methane has a much worse greenhouse effect than CO2. This is why red meat is bad for the environment
Sounds good, but... I'd be interested as to your tillage, seeding, harvesting and trucking power requirements. To be blunt- is this a hobby farm that you operate when you come home from your daytime job, or are you operating 3,000 acres of corn and soybeans? Because 'if every farm did this across America' we would have a famine unprecedented in the history of North America.
@@huges84 You just have to capture that methane and burn it. Yes, you will get CO2 but that is less damaging to the atmosphere! Scrape all that piggy poo into a great big plastic bag and syphon off the gas !
I did some undergrad work in the late ‘80’s with plasmas and a tokamak. The one underlying wish of all the scientists involved was always htsc.. So I am excites that the engineers came up with a way to make the tape that made MIT’s magnet possible! Things should start moving forward much more quickly in the fusion as a power source space.
