> In the right orbit, a solar panel can be up to 8 times more productive than on earth, and produce power nearly continuously, reducing the need for batteries.

Sure. Now do cooling. That this isn't in the "key challenges" section makes this pretty non-serious.

A surprising amount of the ISS is dedicated to this, and they aren't running a GPU farm. https://en.wikipedia.org/wiki/External_Active_Thermal_Contro...

How much are you ready to bet against Elon's plans to scale up Starlink v3 for GPUs? Starlink v3 already has a 60M length solar array, so they're already solving dissipation for that size. Assume linear scaling to many thousands of modules.

From https://x.com/elonmusk/status/1984249048107508061:

"Simply scaling up Starlink V3 satellites, which have high speed laser links would work. SpaceX will be doing this."

From https://x.com/elonmusk/status/1984868748378157312:

"Starship could deliver 100GW/year to high Earth orbit within 4 to 5 years if we can solve the other parts of the equation. 100TW/year is possible from a lunar base producing solar-powered AI satellites locally and accelerating them to escape velocity with a mass driver."
