We have to restart a fast breeder or fast reactor program. There is no choice.

This presentation was largely promotional in nature. They are often presented by those who have fallen in love with a field that is so exotic almost no one else can understand it. Almost all those who do have an understanding of it are lovers of it and are unlikely to see key factors that were not mentioned that could doom development into a commercially practical fusion power plant within 5 to 10 years. The experimentation in this field began back in the 1950s, spawned by hundreds of nuclear fusion physicists and engineers who were just as enthusiastic as Dennis Whyte is. They encountered numerous barriers along the way but keep claiming that a commercially practical nuclear fusion energy power plant was just 20 to 30 years away. Now Mr. Whyte is suggesting that the technology that they have developed has overcome all the problems encountered during the last 70-years of research. The sales pitchers have learned to employ the fear of global warming to convince the press, the public, the government, and private investors to provide them with billions of dollars so that they can continue to play with these fun devices. They've become consistent in leaving out details that don't sell their product. Since the beginning the pitches emphasized that the fuel was virtually unlimited. They typically leave out that tritium is extremely rare, is radioactive and currently has a commercial price of around $30,000 per gram. It is produced in a few nuclear fission reactors that may soon be phased out. The fusion hypers always assume that successful fusion reactors will soon be realized that will have tritium breeder blankets and processing plants that will generate ample supplies of radioactive tritium. The presentations typically mention the Q-plasma value numerous times but tend to rarely elude to the fact that the input energy feeding the facility can often exceed the input energy into the plasma by a factor of over 100. Taking account the energy input to the complex is one of the key factors that determine if a commercially practical power generating station can succeed. Commonwealth Fusion Systems (CFS) SPARC machine will not have a tritium breeding blanket nor an electrical generating plant. There is a strong likelihood that their following ARC machine will also not include a electrical generating plant. All tokamak-like machines will have to operate in a pulsed mode when operating at near maximum fusion power design levels. The released data is typically for the period of time the fusion pulse in 'on.' The 'off,' or recovery time, can be substantially longer than the 'on' period of time. The presentations typically ignore the parameters for the off time and usually for the average of both the 'on' and 'off' time. That average determines the electrical output energy from a fully developed power plant. The SPARC machine is expected to have a maximum 'on' period of 10 seconds when operating at near maximum fusion power levels. The technical literature doesn't state how long the 'off' periods are expected to be. The SPARC designers were expecting to solve some of their ongoing problems based upon fusion reaction experiments that were expected to soon take place at ITER. Due to major assembly problems the start of expected ITER fusion experiments has been extended to 2039. Not mentioned, in the above presentation, is that ITER is grossly over its initial budget and close to two decades behind its original schedule. The nuclear fusion energy promoters live in a delusional world which assumes we can power much of civilization with their dream machines within 10 to 20 years. 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 5.7 years ago. --- Such fusion energy hypers tend to also fail to cite some of the critical assessments of the field. Here are some worth searching for. How nuclear fusion (maybe) works (4) - reactor practicalities (RUclips) Former fusion scientist on why we won't have fusion power by 2040 RUclips) How close is nuclear fusion power? (RUclips) ITER is a showcase … for the drawbacks of fusion energy (The Bulletin of Atomic Scientists) Fusion Has Major Problems That No One Is Telling You About (RUclips) What No One Else Is Telling You About Nuclear Fusion (RUclips) Fusion reactors: Not what they’re cracked up to be (The Bulletin of Atomic Scientists) Is This the ‘Kitty Hawk Moment’ for Fusion Energy?

Is it free like Cambridge? Or other top 💯 universities? Or is it a mill like so many Canadian schools to gain foreign capital?

I know it sounds crazy, but the key to sustainable fusion is in space inside O Neil Cylinders. The main preface for that is you can use HUGE Flywheels as large as the Cylinder itself that are as as efficient as any solid state Capacitor, and you can use their size and speed to provide the necessary energy to keep that much energy coming into the system to sustain it. To have fusion go for that long and be sustainable, it’s almost like your fusion plant has to be the size of a coffee cup, and you have to have Niagara Falls behind it (your Solar Cells and multiple flywheels that are as big as a torus station themselves) Once you have that much energy behind it , you can have laser fusion, with either a sphere or cylinder itself that rotates to have about 30 or 50,000 feet of water to get heated. - that will essentially act as a Dyson sphere, but Significantly Smaller with Solar cells and hot water at the surface (either in pipes or geysers- one or the other) With that Dyson sphere or cylinder rotating, you can have the water and air stick to the walls and convection can work as normal. - with laser fusion in that way, you can have plasma, then you can have superheated air, then superheated water, and then you can go outward because you have that much space. It’s all about scale, and you need a cylinder That big in order to do it. My Name is Michael Skinner, and it’s the only way you can have sustainable fusion that’s efficient enough - Do what you want to do on the big scale, just smaller scale.

Gonna get fucking rocked in 2nd year

Very few comments on this exceptional presentation. This should be watched at least once by the RUclipsrs expressing endless pessimism and negativity re: fusion.

The introduction should be short and be an actual introduction for an online presentation. The introducer took far too long, was boring and monotone, did not impart much interesting information if any, and spent more of her time name dropping and gossiping than she spent introducing. If you want your online presence to be respected you must be respectful to the audience and to their time

I really want to be part of this

Where is Dr Till today. I am curious.

I will be coming to your university next year January I’m from Ghana can’t wait to be there

Thank you, University of Saskatchewan, for your part in educating great leaders like Dr. Till. As a U.S citizen, I'm ashamed that my government cancelled such a crucial and strategic program (IFR), but I'm hopeful will we see the error of our ways and continue this work on advanced reactor development and deployment.

that guy with glasses looks pretty cool actually

Fusion is getting hot hot hot. The research is finally heating up and the competition is getting to where it needs to be. Dumbing it down doesn't help anyone. You aren't playing with fire when you're playing with nuclear fire. Completely different animals. Stop assuming people can relate. Bring them up, don't talk to their level. Do it eloquently. Don't demean them.

🙌 p̲r̲o̲m̲o̲s̲m̲

cool

That's nice of you guys.. planning to apply for MSc in Mechanical Engineering for fall 2023.. could you guys be of help?

I love this presentation. I've forwarded it to a number of people who have asked me about fusion. Well done Dennis!

227 views as of today. Amazing. Thanks for announcing the Apocalypse just too bad our economic system not only rewards insanely unsustainable extraction and pollution of natural resources but also the deep burial of important information under a mountain of shit.

Why is there so much ominous stuff going on here? Maybe I should stay in Calgary and not start Eng there in literally 2.5 weeks

Good job 👏👏 I love this video

How can i register for half speed classes

Would u be willing to send to me in USA a 0.5 kg sample so that I can compare it with untreated isolated pea protein? I'll pay the shipping if you're willing.

The most important lecture of this year. Super exciting and amazing stuff.

ruclips.net/video/Al3JZyCnT5I/видео.html "When we turned this [magnet] on, it consumed 25 watts." 25 watts at what field strength? Is that the full 20 tesla?

How can I enrolled at the University of Saskatchewan as an international student?

So I apply in prequalify application but so far almost 4 weeks done but no confirmation about my M.Eng in Electrical

YOU DIDNT TALK ABOUT THE LAB CLASSES DURING REGISTRATION

Is that Gilbert Le Dressay the same Gilbert Le Dressay from the FCL owned Co-op Refinery Complex (CRC) who was just elected the 2021 Scumbag Of The Year? If so, congratulations Mr. Gil Le Dressay!

Civil engineering ❤ #Bridge Construction. # can't wait to be part of this ❤

Wow ma'am thank for the explanation

Wow great

Nice one geologist. I also love rock.

I am trying to register for classes but I do not see the block registration option

If there is delay in visa processing can i begin the classes online??

I saw the mail today am i still eligible to register for classes

If the permitted date is “30-Aug-2021” does that mean the first day of that class is august 30th?

i dint see computer science/ engineering students?

Does registration open on June 12th?

Congrats to every team of students for these amazing projects

that's a nice video !

hi

Hey! I wanted to ask that can we manage to pay our fees through co ops ?

I cannot get a full screen view of the Feb 11, 2021 presentation.
