> Cooling can be significantly improved due to lower launch costs, heat piping, RTGs, TEGs, and thermoradiative cells, not to mention sunside solar and darkside inline radiators

You're saying they're going to steal the night? We'll see the sun in the day, radiative cooling for surveillance AI in the time formerly known as night?

I'll confess that the numbers aren't nearly as bad as I'd thought. Apparently, you can dissipate 1MW at 100°C with a 17m diameter sphere at night. So it's like the size of a small house. It doesn't even glow. On the other hand, you need a lot of temperature differential to move the heat out fast enough, which means your TPUs are going to be hellishly hot.

Though you'd probably only run it when it's in the sun and radiate in other directions, so you don't have to store the power in heavy batteries. You need a 56m diameter disk of solar panels to provide 1MW, don't forget that.
