Waste heat from data centers can boost air temperatures in downwind neighborhoods by as much as 4 degrees Fahrenheit, researchers at Arizona State University report in a new study conducted in the Phoenix metro area, the hottest in the U.S.
Space-based data centers are wildly impractical to bordering on not physically possible. The largest feature on the ISS, which you can resolve from earth with a pair of binoculars, is the radiators, and it generates 70 kW. Large data centers use >100MW of electricity. You’d be looking at large fractions of a square mile of just radiators.
The radiator panels on the ISS are 2,500 square meters in area. The radiator panels are 645 square meters.
Most of the proposals for space-based data centers have ended up focusing on plans to place thousands of individual satellites into orbit, not just one big space station with everything packed inside it. Scott Manley recently did an analysis of the cooling requirements, he worked through all the numbers and explained how it works, and there really doesn’t seem to be a problem here.
