Addy was like, oh, that's lame.
Like, let's put an H100 on there.
We're like, Addy, you can't put H100 on a satellite.
He's like...
Sure you can.
The amount of people who said it was physically impossible to run a chip that's that power dense in orbit.
People just thought it was literally impossible to run data center grade GPUs on orbit.
What would have caused it to be impossible?
There's two things.
One is the thermal side of things.
They're very power dense.
They produce a lot of heat.
And the second is they've never been tested in the radiation environment or space.
And both of those... So for the first one, it's kind of a wacky solution.
We submerged the entire thing in this phase change material.
So everything on StarCloud 1 is submerged in this phase change material.
So it's like immersion cooling for all of the components, all of the...
Power delivery, memory, everything is submerged.
Nobody's ever considered doing anything like that in space before.
It's not a particularly scalable solution.
