- ceejayoz 5mo agohttps://en.wikipedia.org/wiki/External_Active_Thermal_Control_System https://en.wikipedia.org/wiki/External_Active_Thermal_Contro... All that gets you 70kW of cooling. Radiating to vacuum isn't very efficient.
- scottyah 5mo agoDang, sucks we can never improve any technology. Let's just call it quits, guys.
- ceejayoz 5mo agoTechnology is wonderful. Physics still gets a say.
- cyclopeanutopia 5mo agoMaybe one day we can, but it's definitely not in a category "there is no doubt".
- scottyah 5mo agoOf course not, where's the fun in that category?
- lijok 5mo agoAnd that’s sufficient for roughly 100 unoptimized DC grade H200s. Not efficient, and it doesn’t have to be, because the cooling system has 0 opex cost. And capex clearly can be made to wor
- dzhiurgis 5mo agoCooling space station is very different from cooling off chips. One requires extensive piping, other - a simple radiator.
- ceejayoz 5mo agoBoth require the same thing - moving heat - and you’ll find plenty of piping in a datacenter for this reason.
- joe_mamba 5mo agoSpace radiators are not very efficient due to lack of airflow in space.
- lijok 5mo agoEfficiency in the cooling loop is of no consequence as it has 0 opex cost in space. Do the capex numbers make sense?
