So if you start doing any kind of scaling for both electricity generation and cooling, you realize, okay, space is incredibly compelling.

So...

Let's say you wanted to do 200 or 300 gigawatts per year of AI compute.

It's very difficult to do that on Earth.

So the U.S.

average electricity usage, last time I checked, was around 460 gigawatts per year average usage.

So something like, say...

If you're doing 300 gigawatts a year, that would be like two-thirds of U.S.

electricity production per year.

There's no way you're building power plants at that level.

And if you take it up to, say, a terawatt per year, impossible.

You have to do that in space.

There just is no way to do a terawatt per year on Earth.

And in space, you've got continuous solar.

You actually don't need batteries because it's always sunny in space.

And the solar panels actually become cheaper because you don't need glass or framing.

And the cooling is just radiative.

So that's why I think... That's the dream.

Yes.

That's the dream.
