I think this is well worth reading. I've been a bit frustrated by some over-confident claims that data centres in space are literally impossible due to the cooling issues alone, and other claims that those issues are fairly minor. I am nowhere near close to being familiar with all the real-world engineering nitty gritty; I understand a fair bit of thermodynamics, but that is not enough to really settle things. FWIW, the arguments here seem well grounded in physics and the technological/economic/legal issues raised strike me as plausible.

Can we make the radiators much smaller by running them, say, twice as hot, and actively pumping heat from the electronics into these hotter surfaces? Yes, of course we can, the laws of thermodynamics are fine with that. However ...
