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.
don’t need to think much about this crackpot idea.
where would the heat dissipate? that just ends this topic.
Via radiation into space. All you need is a radiator, the weight of a battleship (or worse). Yes, the idea is crazy.
Around or less than twice the size of the ISS radiator.
