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

So that's how a fission power plant works.

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

It's very important.

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

And when you intentionally design it, that it creates more than one fission reaction per starting reaction, then it exponentiates away, which is what a nuclear weapon is.

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

Yeah, so what you do is you very quickly put together enough of these materials that can undergo fission with room temperature neutrons.

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

And you put them together fast enough that what happens is that this process can essentially grow mathematically like very fast.

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

And so this releases large amounts of energy.

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

So that's the underlying reason that it works.

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

So you've heard of a fusion weapon.

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

So this is interesting is that it is โ€“ but it's dislike fusion energy in the sense that what happens is that you're using โ€“

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

fusion reactions to but it's simply it increases the gain actually of the weapon rather than um it's it's not a pure at its heart it's still a fission weapon you're just using fusion reactions as a sort of intermediate catalyst basically to get even more energy out of it but it's not directly applicable to to be used in an energy source

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

I wouldn't say terrify.

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

I mean, we should be...

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

This is the progress of humanity.

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

Every time that we've gotten access... You know, the day the universe changed.

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

It was really changed when we got access to new kinds of energy sources.

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

But every time you get access... And typically what this meant was you get access to more intense energy, right?

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

And that's what that was.

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

And so the ability to move from burning wood to using coal, to using gasoline and petrol, and then finally to use this is that...

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

is that both the potency and the consequences are elevated around those things.

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

Well, yeah, but see, that's the thing.
