The ISS has 475m^2 of ammonia filled radiators that like to disagree with you. https://en.wikipedia.org/wiki/External_Active_Thermal_Control_System
The whole EATCS radiates 70kW, so less than one modern data centre rack. Helpful!
Hypothetically, a relatively stationary (not doing a lot of accelerating and decelerating) "Space Datacenter" would be a perfect test bed for something like Curie point radiators. Might help with the size of radiator needed to produce the same effect, but that's probably the least difficult problem with that environment. The radiation shielding you would need would be... well astronomical.
Yeah, I've been wondering why there's such a push against the feasibility of space data centers on a lack of cooling when it's in a vacuum where we have already solved temperature regulations. Are there good arguments for why this doesn't work for data centers in space? I mean I imagine other concerns will definitely make it difficult but this argument hasn't seemed accurate to me. I mean also I'm against data centers in general so ya know fuck them but from a reality pov like isn't that argument incorrect?
Sure. What did it cost? How many flights to get it up there? How many human spacewalk missions to maintain it?
