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

So it turns out when you go through the math of this, the average velocity or energy of the particles must be very high to have any significant probability of the reactions happening.

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

And so the center of our sun is at about 20 million degrees Celsius.

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

And on Earth, this means it's one of the first things we teach, you know, entering graduate students.

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

You can do a quick, you can do a quick basically power balance and you can determine that on Earth it requires a minimum temperature of about 50 million degrees Celsius on Earth.

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

To perform fusion.

Lex Fridman Podcast
#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

To get enough fusion that you would be able to make, get energy gain out of it.

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

So you can trigger fusion reactions at lower energy, but they become almost vanishingly small at lower temperatures than that.

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

And this was one of them.

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

So it's interesting because as a scientist, I see the universe through that lens of essentially the interesting things that we do are through the forces that get used around those.

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

And everything works because of that.

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

Richard Feynman had... I don't know if you've ever read Richard Feynman.

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

It's a little bit of a tangent, but...

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

He's never been on the podcast.

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

He was unfortunately passed away, but like a hero to almost all physicists.

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

And part of it was because of what you said.

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

He kind of looked through a different lens at these, what typically look like very dry, like equations and relationships.

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

And he kind of, I think he brought out the wonder of it in some sense, right?

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

For those...

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

he posited what would be, if you could write down a single, not even really a sentence, but a single concept that was the most important thing scientifically that we knew about, that in other words, you had only one thing that you could transmit like a future or past generation.
