>won't need coolingRadiation's the only way to get rid of heat in space and it fucking sucks. You'd need a fucking huge radiator. Probably about the same size as the solar panels used are bigger. Unlike solar panels, the only practical radiators we know of need plumbing. So you need a HUGE area of pipes that can leak when hit by space junk. Because it's big, we'll you're gonna get lots of collisions and leaks. Solar panels can tank a bullet or too, but so far pipes can't. So either we need weird self healing pipes, repair bots that can seal up the leaks, or some new ways to make radiators that can basically withstand hundreds of bullet shots a year
