SpaceX have presented on this and it's fairly straightforward and they already do it with starlink satellites, just at a larger scale. Sound like you are the uniformed one (or an EDS victim)
I've heard this before and these are not comparable at all. Starlink is missing a few digits in it's power usage and heat dissipation needs compared to a datacenter.
EDS? Like still believing Elon's claims are truthful?
Starlink satellites don't generate the sort of heat a datacenter full of GPUs does. The ISS has enormous radiators, and it's only in space because it's a space station. Putting datacenters there is just goofy given the amount of available space on the ground.
