Lex Fridman Podcast · #353 – Dennis Whyte: Nuclear Fusion and the Future of Energy · 21 Jan 2023 podcast

This is low density.

So the way that you do this is primarily, again, this is not exactly true in all kinds of fusion, but in the primary one that we work on, magnetic fusion, this is all happening in a hard vacuum.

So it's like it's happening in outer space.

So basically you've gotten rid of all the other particles except for these specialized fuel particles.

No, actually it's even easier than that.

You connect a gas valve and you basically leak gas into it.

In a controlled fashion.

Yeah.

Oh, this is beautiful.

It's a gas cylinder.

How do you get it from hitting the walls?

Yeah.

So now you've touched on the other necessary requirements.

So it turns out it's not just temperature that's required.

You must also confine it.

So what does this mean, confine it?

You mentioned the magnetic one.

Magnetic one, and there's one called inertial as well, too.

But the general principle actually has nothing to do with...

in particular with what the technology is that you use to confine it, it's because this goes back to the fact that the requirement in this is high temperature and thermal content.
