Random objects floating in space do not have GPUs on them which generate heat. You need to move the heat from GPUs to a radiator, so you are describing the actual solution of radiators in a roundabout way. Radiators weigh an amount and cost money. The consequence of factoring this in with optimistic assumptions is that it's about 1/4 as efficient to build space compute as earth compute. It's hype bullshit.
