Ah yes: computation. Famous for annihilating water. Every bit you flip consumes an H2O molecule.
replyWell, how do you cool servers in space then?
replyEvaporative cooling is the way it happens down on earth - and that shuttles h2o molecules from dense useful clumps like aquifers and rivers to a less useful form spread out in the air. But evaporating h2o isn’t an option in space afaik - since there’s a shortage of air to take up the h2o. In fact I think radiative cooling is the only actual option in space.
That's the neat thing: you don't, or at least not in the megawatt range. A kilowatt can be done with radiative cooling but doesn't get you far with a hypothetical datacenter satellite.
replySo, somehow the servers can run hot in space without a problem?
replyNo; if you try to do this you don't launch in the first place because the amount of servers required to be useful can't be cooled within your payload budget.
replyMy job is mostly worrying about cooling paths, maintenance, power, heat transfer, lifetime of GPUs, and high performance networks. NVIDIA partner. I can drive to the datacenter. This stuff BARELY works here on Earth. Especially thermal issues.
replyLooking forward to watching spacex defeat physics.
