    Via radiation into space. All you need is a radiator, the weight of a battleship (or worse). Yes, the idea is crazy.

        That gives you a heat rejection capacity of less than 140 kW (mind you, that is total heat rejection, incl. heat from the sun, support systems etc., only a part of that can be used to cool servers) So you settle for laughably low compute to keep radiator size somewhat reasonable, yet still massive and heavy.

          The ISS is rated for 84kw but is run max at 70kw, probably for margin of error and whatnot since its for human saftey, which these will not be. They can also probably run hotter, (edit reducing the size).

          The compute is 125kw avg per dish. 150 peak.
