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

So there's a lot of interesting engineering ways that we can bring those two together.

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

So when I talk to AI experts, they talk pretty routinely about the power needs for AI.

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

And in fact, in the same way in manufacturing, that the cost of any one thing asymptotes to the raw material.

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

For AI, the cost of computation asymptotes to the power, to the cost of the electricity.

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

And even more, that electricity is concentrated.

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

It's in that AI data center, that brain where all the power is.

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

And you really want a lot of high energy density.

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

You want power generation right there on site.

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

So it seems like, just take those two facts, a really nice match between fusion, which is baseload, high energy density, can be cited most places, and a data center, which is going to be high energy requirements and a local data center.

location and large amounts of it.

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

There's been predictions recently from energy institutes that suggest we will have growth that, rather than a 2% growth per year in electricity, maybe a 4% or 6% growth in electricity due to data center use.

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

I think that is probably wildly underestimating where we're moving.

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

And so...

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

Oh, man.

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

And so the idea that AI can grow human cognition and our ability to solve problems...

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

We can't let it be limited by power.

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

And so I'm going to push as hard as I can so that that's not the limit.

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

So I tell the team that if we demonstrate fusion one time and that's it, then we failed.

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

But that's not enough.

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

The universe is powered by fusion.
