#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

And that's a project called ITER, which is under construction in the south of France right now.

#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

So its scientific purpose is a worthy one that it's essentially, in any fusion device, the thing that you want to see is more and more relative amounts of self-heating.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

And this is something that had not been seen, although we had made fusion reactions and we'd seen small amounts of the self-heating, we never got to a dominant... This actually goes to this QP business, okay?

#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

The goal of ITER...

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

And it shifted around a little bit historically, but fairly quickly became, we want to get to a large amount of self-heating.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

So this is why it has, its primary feature is to get to QP of around 10.

#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

And through this, this is a way to study this plasma that has more higher levels of self-determination around on it.

#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

But it also has another feature, which was, let's produce fusion power at a relevant scale.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

And, and actually they're linked together, which actually makes sense to think about is that because the fusion power is the heating source itself, this means that they're linked together.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

And so ITER makes, is projected to make about 500 million Watts of fusion power.

#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

So this is a significant amount, like this is what you would use, you know, for powering cities.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

Yeah, yes.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

So this meant then, too, is the development of an industrial base that can actually produce the technologies like the electromagnets and so forth.

#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

And to do it with, it is a tokamak.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

It is one of these, yes.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

But very interesting, it also revealed limitations of this as well, too.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

Like what?

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

Well, it's interesting is that it is clearly a โ€“ on paper and in fact in practice as well too, the world โ€“ and very different political systems and you consider at least geopolitical or economic rivals or whatever you want to use.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

Like working towards a common cause and one that we all think is worthy is very like, okay, that's very satisfying.

Lex Fridman Podcast
#353 โ€“ Dennis Whyte: Nuclear Fusion and the Future of Energy

But it's also interesting to see the limitations of this.
