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

This is the nature of a lot of cooling technology we use, actually.

Well, the opposite is true, that if you would take all of those particles and jam them together very fast back in, they want to heat up.

And that's what happens.

And then what happens is you basically have this very cold compressed set of fusion fuel.

And at the center of this, it goes to this 100 million degrees Celsius.

And so if it gets to that 100 million degrees Celsius, the fusion fuel starts to burn.

And when that fusion fuel starts to burn, it wants to heat up the other cold fuel around it.

And it just basically propagates out so fast that what you would do ideally, you would actually burn in a fusion sense, most of the fuel that's in the pellet.

So this was very exciting because what they had done was

it's clear that they propagated this, they got this, what they call a hotspot, and in fact that this heating had propagated out into the fuel, and that's the science behind inertial fusion.

10 times a second or something like this.

So you have to make the BBs very fast.

There's reports on this, but about what does it mean?

The starting point is, can you make this gain?

So this was a scientific achievement primarily.

And the rest is just engineering.

No, no, no.

The rest is incredibly complicated engineering.

Well, in fact, there's still physics hurdles to overcome.

So where does this come from?
