People don't understand just how difficult it is to cool stuff in space. Half of the shit sticking out of the ISS that people think are solar panels are actually radiant cooling systems, and the ISS will generate WAY less heat per volume than a data center.
Not to mention the power requirements would likely require more than solar unless they put solar panels up far bigger than anything put up there before.
Beyond the power requirements for the computer, there is also the power that will be needed to transmit back to earth.
A wireless link that can pass the amount of bandwidth needed (and do it reliably) will need huge power as well.
It will be far bigger. Its mostly solar panels.
Or one of those mini nuclear reactors they are working on
If we did make something like that, could you even put it on a disposable dish meant to burn up in the atmosphere after 5ish years? There's already uncertainty about all the dishes burning up and long term impacts, but a mini nuclear reactor?
No. At least historically they went the opposite way: the nuclear materials be contained well enough to survive reentry and impact
Im seeing the ISS needs to reject 70kw with a max ability of 84kw. The datacenter dishes will be between 125 and 150, so around double or less.
