> But what is being discussed are 100 MW space data centers. Make the calculations....Those need a 20 x 20 mile radiator and a solar farm the same size. Those are space constructions at scifi level maybe for the next century.

No one is talking about building a single massive structure. SpaceX has said they’re targeting 100kW satellites. A lot of them. Which they’re already pretty good at.

Technically it’s pretty straightforward. The only real challenge is making it cheap enough.
