    LOL LOL you CANNOT cool something like that in space. The entire concept is flawed.

      You can, they just have to be smaller rather than a massive single orbital data centrer like this proposal. https://www.youtube.com/watch?v=FlQYU3m1e80

      Still not a great idea because of the economics, but the same can be said for the data center build out on earth too, so why would they let that stop them?

        For scale. roughly a two server datacenter needs to have solar and radiator about as big as the ISS.

        Which is possible, but insane. However insane plain old datacenter is, just tons more insane.

          That simply isn’t true, the video I linked explains everything clearly, for a 20kw satellite the cooling area is needed very modest.

          Still not a great idea and I am not advocating for it, but people need to stop fighting bullshit with bullshit and start fighting it with truth.

            For reference, a GB300 server is now at about 8.5kw for a single server. A fully populated NVL8 server is about 15kw. Looking online, looks like the ISS is about up to 90kw, so I guess I’m off and the actual number is something like 6 to 10 of these servers per ISS scale facility.

            I would still argue this is a crazy overhead for what they would now consider meager capacity, with, luckily for nVidia, a pretty hard deadline where the very expensive equipment burns up without potential for extended lifetime use.
