My concern is more in the realms of cooling. I know there's the potential for lots of 'free' energy up there, but how do you then ensure your space-based array of GPU farms bleed all of the resultant heat?
- alephnerd 2mo agoFrom a Defense perspective, it's acceptable if multiple ODC fails and you have to re-launch another one. This is why these are being treated as part of a mesh. These aren't supposed to be a commercial DC and are intended to be a mesh of multiple racks in orbit. The fact that the US, China, Russia, and India have already deployed ASATs means a Kessler effect if a question of when and not if.
- laughing_man 2mo agoThe Russians put the first ASats up in the '70s. Their existence doesn't require use.
- alephnerd 2mo agoThe difference is India and China had an orbital near-miss in 2024 [0] and both India and China now field ASATs. It's a matter of time before Japan, SK, Iran, Israel, UAE, KSA, etc build similar capabilities.

- TeMPOraL 2mo agoThis is like "how do you ensure you can bring back home all the groceries you bought" kind of problem. Space 101. We know how much heat we can bleed off, how, and how fast, and this gives us bounds on how much power we can use, and that is the starting point - you design everything around that.
