  Fascinating. Will look more into it to understand.

    I think Scott Manly might have had a video on it (data enter in space) recently. I saw it on a feed but haven’t watched it. I’m sure he would mention the issues with heat removal.

      TLDW: cooling’s fine if you use starlink V2 size and power (which is not very suitable for AI ‘datacentre’ use) because it works already.

      This is not about a few huge datacentres, it’s about a million small ones. There’s 99 problems with this (see Kessler syndrome !, radiation, …), cooling isn’t (much of) one.

      Doesn’t matter anyway, it just has to be vaguely plausible for a stock IPO pump (and dump) scheme while sweeping all that xAI debt under the rug.

      Doesn’t say why a vacuum cannot conduct heat though, but it makes sense to me now anyhow. Heat is vibrating molecules so to mitigate the vibration you need adjacent molecules which aren’t vibrating as much.

    Read the traveller sourcebooks, they especially for the ship designs. Good stuff
