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

That's the other part of it.

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

So by the way, this is what...

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

very much distinguishes it from fission.

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

It's not a process that can run away from you because it's basically thermally stable.

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

That means is that you want to run it at the optimization in temperature such that if it deviates away from that temperature, the reactivity gets lower.

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

And the reason for this is because it's hard to keep the reactivity going.

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

Like it's a very hard fire to keep going, basically.

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

It varies from concept to concept, but in generally, it's fairly easy to do that.

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

And the easiest thing, it can't physically run away from you because the other part of it is that there's just, at any given time, there's a very, very small amount of fuel available to fuse anyway.

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

So this means that that's always intrinsically limited to this.

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

So even if the power consumption of the device goes up, it just kind of burns itself out immediately.

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

Fusion is interesting because it's not really directly weaponizable because what I mean by that is that you have to work very hard to make these conditions at which you can get energy gain from fusion work.

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

And this means that when we design these devices with respect to application in the energy field, is that they, you know, while they will, because they're producing large amounts of power and they will have hot things inside of them, this means that they have like a level of industrial hazard, which is very similar to what you would have like in a chemical processing plant or anything like that.

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

And any kind of energy plant actually has these as well too.

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

But the underlying, underneath it, core technology can't be directly used in a nefarious way because of the power that's being emitted.

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

It just basically, if you try to do those things, typically it just stops working.

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

I mean, usually what we worry about is the viability, because in the end we build pretty complex objects to realize these requirements.

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

And so what we try really hard to do is like not damage those components, but those are things which are internal to the fusion device.

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

And this is not something that you would...

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

consider about like it would, as you say, destroy human civilization because that release of energy is just inherently limited because of the fusion process.
