Physics suggest "heat dissipation is extremely hard in vacuum".
Energy harvesting on the scales that these AI DCs need is also not
exactly trivial - under ideal conditions a square m will see something
like 1.3kW of influx energy. So for people talking about "gigawatts"
of DC power, you'd need a square kilometer of solar collector, with
good efficiency...
