There is often a knee-jerk reaction against data centers in space, but the more you dig into it the more the numbers look like they work if a number of difficult, but not impossible, engineering challenges are solved. Many people list cooling as a major blocker to space data centers, but this is already solved by using large radiators. Additionally, there are technologies like the liquid droplet radiator that could reduce radiator mass by up to 7x (see diagram for design variants). The general idea is that you simply yeet the coolant into space and catch it again once it has cooled off, using the surface of the liquid itself to radiate heat instead of a heavy network of pipes and metal. A droplet of coolant with a diameter of 1 μm can theoretically go from 227 C to -21 C in two seconds given the proper conditions. A major open challenge with liquid droplet radiators is preventing coolant loss. Not sure if @elonmusk 's team is working on this, but would be curious to know if anyone else is.
