I don't pay attention to his idiotic claims that much because a lot of them can be debunked within 1 second because Elon just talks out of his ass. But in space, we don't have conduction nor convection, so heat is transferred outside the object by radiation. There is radiation coming in from the sun and radiation coming out from the object too. And we can have temperature control by changing the surface so that it emits or absorbs heat better so everything is at precisely the right temperature.
That's a good point. Elon has never admitted how the radiation sails will make the datacenters appear as bright stars in our sky. 10x more radiators needed than his Starlink satellites, which people already complain about.
Yea. That is a problem since most people don't want to see streaks of light when they are looking through their telescopes. But people don't realize how mindbogglingly stupid it is to build data centers in space.
Oh. And are we going to do that in near-Earth orbit? Because if we do, all that space shit will make space so full of debris flying anywhere that NOBODY WILL BE ABLE TO LAUNCH SATELLITES. I am looking forward to this, so I will launch my own company called SpaceSex where we will just send a whole bunch of caltrops into orbit to fuck up all satellites. LONG LIVE KESSLER SYNDROME. And if we are going to do it far from the surface of Earth, good luck paying to get it all the way up there as SpaceX is only good at getting things in near-Earth orbit.
