| Well, how do you cool servers in space then? Evaporative 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. |

| ▲ | kennywinker 2 hours ago | parent [-] | | So, somehow the servers can run hot in space without a problem? | | |
| ▲ | MrMorden 2 hours ago | parent [-] | | No; 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. |

| My 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. Looking forward to watching spacex defeat physics. |
