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

Yeah.

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

Um, so it's interesting is that this, so this is one of the hard parts.

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

So this means that the individual units, you know, and it's, it, it varies from concept to concept, but the, the, the national academies report that came out last year sort of put the, the benchmark as being like, probably the minimum size looks like around 50 million Watts of electricity, which is like enough for like a meat, like a small to, you know, midsize city actually.

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

Um, so that is, uh, so that's sort of like a scale challenge.

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

And in fact, it's one of the reasons why in Commonwealth and in other private sector ones, like we, they try to push this down actually of trying to get to the, to these smaller units just cause it reduces the cost of it.

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

Um, then probably, um, obviously, I would say it's an obvious one, like achieving the fusion state itself and high gain is, is

is a hard one, what we already talked about.

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

Well, that's achieving the right temperature, density, and energy confinement time in the fuel itself, in the plasma itself.

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

And so some of the configurations which are being chosen are actually, have quite a ways to go, in fact, of seeing those.

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

But...

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

What their consideration is, oh, yes, but by our particular configuration, the engineering simplicity confers like an economic advantage even if we're behind in sort of a science sense, okay, which is fine.

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

This is also what you get when you get an explosion in the private sector.

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

You basically are distributing risks in different ways, right, which makes sense.

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

All of that good.

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

So what I would say is that the next hurdle to really overcome is about making net electricity.

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

So we need to see a unit or several units using fusion in some way to put a meaningful amount of energy on the grid.

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

Because this starts giving us real answers.

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

as to what this is going to look like.
