Yes, I watched the video. It’s talking about solar and radiators. I agree, if we can solve solar and radiators, it’s feasible tech.
I’m still not entirely sure it’ll be competitive with solar data centers on the ground. I realize I’m no expert, but it just seems like a bizarre way to do computing.
Everything I like about Space X is about doing things that you can't do on earth, because you can't do them on earth feasibly.
