My question is always how the hell are you going to cool them. Do you know hard it is to move heat in a vacuum?
The problems; plural; is that the person who popularized the idea of data centers in space has little to zero understanding of any of the space sciences and yet owns and directs one of the world's largest, and privately owned, aerospace companies with massive government contracts that splits its time with their own AI work.
Have you never seen a movie set in space? Evrytime someone gets sucked into space they freeze. You saying every movie got it wrong?? Space is cold. Duh.
Please tell me you aren't serious.
They are completely cereal!
Super cereal
With extra milk
dude! how do you expect anyone to answer if you don't say surely you can't be?
I am serious, and don't call me dude!
Easy, just create a long heat sink and dangle it in the earth’s atmosphere. Now we are winning!
From that to a space elevator...
Raditors. Starlink v3 can in theory already shed (edit 20) kW of heat. But they would need to figure out how to 5x that and keep things profitable.
It would be 20kW for each rack or two. The types of data centre deal they talk about these days are measured in GW of compute. That's 50,000x just for 1GW.
These aren't big things, they're small satellites. They're going to be ~100kW. They only need to 5x the existing radiator they think will work.
