> A 1 m^2 radiator in space can eliminate almost a kilowatt of heat.

Assuming that this is the right order of magnitude, a 8MW datacenter discussed upthread would require ~8000 m^2, plus a fancy way of getting the heat there.

A kilowatt is nothing. The workstation on my desk can sustain 1 kW.

Why are you assuming active heat transfer? Passive is the way to go.
