Such a shame elon musk isnt interested. If we had his money/enthusiasm we could actually do fusion.

Industry spokesman giving the thumbs up to fusion. Poindexter, you're a stakeholder. The industry you work for pays your wages.......there was a reason you were bullied at school.

When I was a kid I remember reading about how we were all going to have flying cars. Now I’m 69 and there still aren’t any on the dealers lots. I predict that when my grandchildren are 69 years old they will still be hearing how fusion power will someday change the world. 0:27

The Bulletin of the Atomic Scientists' November issue is "FUSION - The next big thing... again?"

Fusion: The energy of the future that will always remain so.

It feels so good to be a dreamer. 😅

"2024 sees the hottest summer on record..." Humm, this whole climate change thing is pretty controversial. Statements such as these are dubious at best. Can you back it up with data? If so, why did you not do so? Such statements, without backing, undermines your credibility! The fusion industry really can't afford to lose credibility!!! BTW I wish you guys all the best and hope you succeed in creating viable, lost cost energy for all of humanity!!!

Nuclear fusion energy promoters, such as the one above, typically employ deceptive descriptions to sell the products that they have fallen in love with. I will describe a couple of the tricks below. When they describe the fusion energy gain they typically do not make it clear what energy parameter they are using. Typically the gain value they quote is denoted by the symbol Q. In virtually all cases they are referring to Q-plasma which is the energy that is coupled into the plasma that ends up heating it. That energy value can be many orders of magnitude less than the energy needed to power the entire reactor and all its support systems. That value is often referred to as the net energy input, or the total energy input. Its value is used to formulate Q-total which is the value that is essential for any engineer that intends to design a power plant. Another factor that is never expressed is that most tokamak designs will have to operate in a pulsed mode when they are operating at near their maximum designed D/T fueled fusion energy level. Commonwealth Fusion Systems (CFS) SPARC is expected to have a 'ON' time of ten seconds. The recovery period could be far longer. The Q-fusion value only applies to the 'ON' period of time, not the total of both the 'ON' and the 'OFF' time which is what the Q-total is based upon. The nuclear fusion promotional community also tends to use the term 'ignition' in a misleading way. For most people they associate the term ignition with something akin to the striking of a fire-match. In that case once the reaction begins at one point it it spreads, or propagates, until all the match head fuel has been consumed, without any continuing input of external energy. Nuclear fusion energy in earth-bound reactors isn't anything like that. There is no guarantee that a substantial percent of the supplied, every expensive fuel, will be consumed once the fusion conditions are reached in a small volume of the confined plasma. For example, in the widely announced December 5, 2022, laser shot at the National Ignition Facility (NIF) the fusion reaction began in the center of the extremely compressed fuel plasma and then several forces resulted in the outward movement of fuel in a violent explosion. The fusion reaction only lasted for approximately 0.000,000,000,08 second and then the remaining 96% of the unfused fuel was blasted away, and rarified, from a point where it could react. That unfused fuel was sweated away into the target chamber vacuum system, including the radioactive tritium. There are good reasons the lab didn't bother to describe that portion of the process. The fusion energy released was about enough to boil two liters of water but the energy required, to pump the lasers, was more than 100 times greater for this so-called 'breakeven' experiment. Also unmentioned, or skillfully obscured, was the fact that the NIF has always been primarily funded as a thermonuclear weapon (H-bomb) research tool. In fact that announced experiment included a weapons related target that was exposed to the prompt flux of 14.1 MeV neutrons generated by the fusion reaction. That 'breakeven' experiment was supposed to have been achieved by 2012 but that target was missed by a factor of over 100. Major tweaking took place in many systems over the next decade. The target assembly cost has been estimated to be over $100,000 for the announced shot. Much of it was vaporized by the experiment. It has been estimated that NIF has already consumed more than $11-billion in federal revenues. The administration has always portrayed the machined as a viable path to a nuclear fusion energy power plant whenever they address journalists and the general public.

This is a promotional organization that capitalizes upon fundraising efforts to keep funding flowing to over a dozen nuclear fusion energy experimental programs, a research effort that began in the 1950s. They have no shame in regard to deceiving journalists, the general public and the funders, in regards to the actual prospect of achieving a commercially competitive power plant before Anthropogenic Climate Disruption (ACD) effects overwhelm the many efforts. Virtually all nuclear energy promoters, are in line with the vast majority of Earth's other 8.0+ billion humans, who continue to assume that we still have at least 20 years left to turn this 'Titanic' around using their favorite nuclear technology. They have become masterful in excluding the following warnings from their consciousness. I urge readers to search for the following two article titles. IPCC report: ‘now or never’ if world is to stave off climate disaster (TheGuardian) UN chief: World has less than 2 years to avoid 'runaway climate change' (TheHill) * This statement was made 5.8 years ago.

The nuclear fusion energy experimental programs began in the 1950s and typically the promoters claimed that the hydrogen fuel was plentiful. There must be financial reasons you spokespeople never mention that the tritium component of the typical fuel mix is radioactive and has a commercial cost of approximately $30,000 USD per gram. Also why do you folks typically leave out the fact that almost no experimental machines employ tritium and therefore don’t generate significant numbers of fusion reactions? Has promotional zeal overtaken your ethics?

I'm sorry,Please let go 🙏😭

Thanks to these startups fusion reactors are no longer permanently 30 years away. Now they're permanently 10 years away... 😅

lol, tag for Canada is in middle of Alaska. @1:47

Exciting times! Thank you FIA for helping push commercial fusion!

☕️

ZPM, Zero Point Module is such a better name. SG Ftw

Those headlines are rubbish. Someone set a record, someone gave some details, government gave some money generally, bleh

Thotty like a torque wrench-got me all twisted.

4:03 The French company Thales is not to be pronounced in the English way, it is to be pronounced in the French language way: TALESS ( The H is silent )

Please 🙏🏻! USE A TIE MIC, to suppress the room sound ambience, it is very annoying and makes your voice very uncomfortable to listen too. As another comment said, use normalization on your audio recording to optimize it.

3:04 It would be important to know how much power from the grid is necessary to produce those 1.3 MW of radiowave power.

Please fix your audio and use proper audio normalization techniques.

Please fix your audio and use proper audio normalization techniques.

Thanks, but please use an external good microphone to enhance the experience.

I don’t believe Tokamak Energy’s reactor will ever be built. How will they know how much tritium will be needed in the start up period before tritium breeding comes on stream? How will they know whether the breeding ratio will be sufficient, and how will they know whether the predicted DT power will be achieved? These things surely need to be known with complete certainty before spending Billions of Pounds/Euros/Dollars building the machine.

*Fusion NOW*

Thanks for the update Jasmine!

Jasmine, excellent presentation. I have two questions. (1) why is that globe behind you black? (2) was there no ICF news this week? In the previous Fusion News, Cyd (Dr. Cowley) linked to an article, by Mordecai Rosen, titled "The long road to ignition." The article (27 pages) was surprisingly entertaining and informative. It explains that volumetric fusion yield is proportional to density squared, according to the formula: Yield = Volume * Time * <sigma v> * Density^2. However, this is generally not true because a target's Density, Mass, and Volume are not independent variables. For example, there is a problem in thinking that a target's density can change while its volume is held constant. We need to remember that a target's mass is fixed and cannot change to compensate. Because a target's mass is fixed, a better, more useful model, treats the fuel as a uniform (but variable radius) sphere of plasma with a specific (constant) mass. Under that model, the yield would be proportional to (mass/radius)^2. In that model, it would take 10x the energy to heat 10x the fuel to the same <sigma v>. If during that 10x heating the radius was also increased 10x then the yield should remain unchanged, since (mass/radius)^2 = ((10*mass)/(10*radius))^2. However, the larger target is more robust, easier (requiring less precision) to manufacture, experiences less instabilities, and would have better energy confinement time due to its surface-area to volume ratio.

A small crucible containing plasma 100 times hotter than the centre of the sun seems to me impossible to be honest.

This site frequently cites articles presented on the news aggregator site 'Interesting Engineering' (IE) which is based in India. IE tends to employ writers who often have no academic background in the technical field that they are reporting on and who do a poor job of confirming their information sources using independent experts. They typically don't include outside critical assessments in their reporting. In the following article they report on a cold fusion energy startup, ENG8' which currently refers to the process as 'catalyzed fusion' since 'cold fusion' experiments were typically found not to be repeatable experiments by independent experts. Catalyzed fusion system produces electricity, runs indefinitely without input power (Interestingengineering)

I hope that they are doing well. SPIN OFF😢

Spin off. Could you explain more about this 😂

Really good Fusion Industry update Dr. Cyd!! Lots of interesting developments in Fusion tech and associated spin-offs of tech to other unrelated applications! I haven't seen any updates from Helion Fusion in a while. I'm especially interested in their technology and processes for achieving Fusion!! Thanks for this update Dr. Cyd!!

is that one minute, forty eight seconds of energy pulses, assuming ten pulses per second? 1080 pulses, doesn't sound a long time, must be difficult?

Fusion is a fairytale that is always just around the corner and nothing but a total swindle! There is no such thing as high temperature fusion and all these advocates are crooks that should be jailed!

Great video Cyd!! Thanks again!

In the Bonus "Harnessing Star Power Part 2," I was confused by comments from professor Dennis Whyte. In the standard approach to laser ICF, after the laser fires, the compressed/heated fuel target instantly expands into the vacuum chamber at the speed of sound. Because expansion shortens the length of time that favorable fusion conditions last, it reduces self-heating and total burnup. It is often said that a material wall cannot be used to slow the expansion (or reduce the cooling) of the fuel, because contact with matter quenches the fuel. This is not true. ICF capsules use non-fuel "pushers" to compress the fuel and non-fuel "tampers" to slow the expansion down. Containment can also be improved by surrounding the fuel with a high-Z material, and suddenly heating them to the same extremely high temperature (high enough to become fully ionized). For example, consider a bubble of compressed DT gas in molten lead. Since the temperature is the same, the radiation pressure in both regions will be the same. The contribution of the particle pressure to the total pressure will be proportional to the particle density. Initially (assume), in the un-ionized state, the particle densities were about the same. Once the atoms become ionized, the particle densities can change dramatically with far more electrons becoming available from dense high-Z materials compared to low density, low-Z materials. Even if the system is radiation dominated, with the radiation pressure far exceeding particle pressures, the total pressures in the regions will not balance. The pressure differential will cause the high-Z material to expand, compressing the low-Z material. This process of ionization compression can be very important in a system where a high-Z material directly contacts low-Z material. In fact, it is interesting and relevant to note that the main effort Soviet scientists made towards an H-bomb was the "Layer Cake" or Sloika design. It employed Vitali Ginzburn's idea of using solid lithium-deuteride fuel and Andrei Sakharov's notion of ionization compression of the fuel. OMG! The zombies got my favorite Pod caster.

Commercial electricity generation from fusion is impossible, by basic Physics. All the Rube-Goldberg schemes in the world can't obscure the basic input output accounting fact that energy in will always exceed energy out. Anyone claiming otherwise is either leaving out key energy inputs, or making claims of impossible outputs.

The Fusion Industry Association is primarily composed of fusion energy fans, most of whom have vested interests in promoting numerous aspects of nuclear fusion experimental efforts. The field is currently spending billions, worth of USD, on dozens of experimental facilities located in numerous countries and now involves hundreds of contractors and many tens-of-thousands of people. Investments tend to be based upon ‘critical assessments’ generated by other fans, not from completely disinterested parties. The promotions tend to cherry-pick the positives while leaving out key issues that have plagued the field since the experiments began in the 1950s. It has always been claimed that the hydrogen fuel is virtually unlimited. In most cases tritium is essential. Typically not mentioned is that it is radioactive and that its current commercial price is about $30,000 (USD) per gram. As a result exceedingly few fusion energy experiments utilize it so there is no chance that they will generate a significant amount of fusion energy as part of their experimental program. That fact is frequently not conveyed to the press, the public and to funders. Almost all the proposed magnetic confinement fusion (MCF) demonstration power reactors are expected to operate in a pulsed mode when operating near their maximum fusion energy level. The pulse ‘on’ period of time is sometimes mentioned but not the ‘off’ period of time, or recovery period. If the off period is much greater than the on period then the peak generated fusion energy will need to be far greater than the average thermal energy that the plant is designed to produce. The constant thermal cycling will likely reduce the lifetime of the plant. The energy gain (Q) was mentioned in the above video. It refers to Q-plasma, not Q-total. Q-plasma is based on a very limited input energy parameter, the energy that couples to the plasma to heat it. It only applies to the pulsed ‘on’ period. It has almost no relationship with the input energy needed to power the entire system, including during the recovery time period. Zap Energy’s Century machine is not intended utilize a D/T fuel mixture so it will never produce significant fusion reactions. If it did the fusion reactions would likely last far less time than the arc pulse and the fusion reactions generated would likely disperse the remaining fuel nuclei before they have a chance to react. As a result much of the expensive fuel would likely be sucked into the chamber vacuum pumping system. The video included news on the JT-60SA machine. It made no mention if it will ever employ D/T fuel and therefore generate a significant amount of fusion energy. It didn’t mention that this announced goal is years behind its original schedule and that a predecessor superconducting magnet experienced a catastrophic short circuit. JT-60SA was expected to complement the work at ITER which is now grossly over its original budget and more than a decade behind its original schedule. The ITER directorate recently announced that their D/T fusion experiments are not likely to happen until 2039 and this is too late to deal with Anthropogenic Climate Disruption (ACD) effects. The news article, promoting the many potential uses of high temperature superconductors ( HTS) failed to mention the key issue that they typically require cooling down to liquid nitrogen temperatures, or below that temperature. Nuclear fusion experimental research has resulted in many manufactures investing in SC cable manufacturing equipment so they are now trying to create other markets for their products even though it is not cost competitive with existing technologies. I suggest that these vast resource would be better spent on technologies that are currently making some progress in weaning us off the fossil fuel nipple. All promoters of nuclear energy are in line with the vast majority of the Earth’s 8.0+ billion humans who have masterfully excluded the following warnings from their consciousness. They continue to assume that we have at least 20 years left to turn this ‘Titanic’ around, through the use of their favorite technology. I urge readers to search for the following two article titles. IPCC report: ‘now or never’ if world is to stave off climate disaster (TheGuardian) UN chief: World has less than 2 years to avoid 'runaway climate change' (TheHill) * This statement was made 5.8 years ago.

Nope.

Thx great news as usual - can you add timestamps for the different news pls?

Great job as always

3:14 The World Wide Web and the Internet aren't the same thing. Tim Burners Lee invented the World Wide Web, not the Internet.

Thanks 🙏🏻 for your very informative videos ❤

0:51 I've been following this concept for more than 20 years, and find it interesting from the physics point of view. It would be important to know how does their neutron yield energy compensates the energy which is invested in the pinch, though. 6:22 The real significance of the JT60-AS isn't so much its increased volume, but its capacity for testing longer plasma pulses. It should soon outperform China's EAST tokamak.

Amazing news. We are closing to an industrial application of fusion. Let's bet the UK will achieve it first.

Great news, thank you for explaining
