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

The smaller ones, the smaller plasma systems, we've gone from zero from off to all the way up to 100 times a second and shown we can do 100 Hertz operation.

In fact, that system we ran for over a billion operations and just ran it steady all day long.

Each individual pulse is different where you put in your fuel, you do fusion, you exhaust it.

Cool.

through those pumps from eBay, and then power output and electricity output.

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

But there's probably some more clever ways to do this.

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

And when we founded Helion, the goal was to build low-cost baseload electricity.

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

And what we started to see, working with Microsoft, working with others now, that data centers are going to be one of the biggest power needs in the future.

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

And we know that's coming up.

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

And what's really unique is that power in this form is direct

recovery, not the steam turbine part, but direct electricity is already DC, which is steady, which is what computers really want anyway.

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

And so are there really unique ways to take DC power sitting on this capacitor and rather than going AC to the grid and having all these transmission losses, just going direct DC to the data center?

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

Can you plug right in?

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

And so that's some of the things that my team is looking at now is can you do that direct DC conversion at super high efficiencies and run those GPUs directly?

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

That would be really powerful.

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

We could figure out how to do it.

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

But those are some of the things that I think there might be some unique ways that fusion and data centers can really couple together.

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

There's a whole cooling part to it, too.

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

Most of my cooling is cooling semiconductors and cooling power switching.

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

just like a data center.
