Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

We know this can be done.

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

And so for fusion, the call is there and the market is there too.

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

If you can get electricity generators cheap enough, then it's worth doing.

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

And so if we can get to that, if we can get to making a generator a day, you're not now talking about hundreds a year and you're deploying and deploying them is, is also hard at this scale.

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

Um, how do you go and deploy power plants and deploy generators at this scale and do it quickly?

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

Interestingly, data centers are a little bit of a nicer challenge in that way, because we wouldn't build one 50 megawatt system and have to go build a site for it.

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

We would build a site and put 100 of them on that site and have large amounts of power for that large data center.

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

And so that in some ways is actually in the chicken and egg problem of how do you go deploy hundreds or thousands of fusion generators?

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

Data centers are an interesting application where very immediately you need a lot of power in a very small area and you can go do that.

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

Now, what does that mean?

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

That means I'm gonna need more than two conveyor belts.

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

That's for sure.

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

So the Kardashev scale, Kardashev type one civilization is when humans are either catching or generating as much power as what's incident on the earth from the sun.

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

Type two is the next big one where you're catching as much energy from all the way around the sun.

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

So massive amounts of energy.

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

And a lot of times people talk about it as energy.

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

incident, as in you had solar panels the size of the entire planet blocking all of the sun.

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

But I think really you should be thinking about it as, what can we generate?

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

What can we make here on Earth?

Lex Fridman Podcast
#485 โ€“ David Kirtley: Nuclear Fusion, Plasma Physics, and the Future of Energy

And what we know is that we're only a fraction right now of Kardashev Type 1, and we've got some work to do.
