宇宙の断熱が高レベルって事は違う部材に熱を移して切り離せば熱も切り離せるから、
放熱モジュールを多数作って切り替えながら使うとかもできそう。

Musk doesn't think space cooling is easier because space is cold. He thinks its easier because it's a strait forward engineering problem that scales well.
Cooling in space is indeed difficult, because vacuum is an insulator.
But it's also straightforward, you just need a radiator.
Since 99% of the heat you are radiating comes from power consumption produced by solar panels, the amount of radiator panels equals a percentage of solar panels. It's around 25%.
The International Space Station has ~2,500 m² of photovoltaic panels generating power, and ~645 m² dissipating the heat.
There is no scale problem like there is on earth -- you can just keep building bigger and bigger and bigger.
Scaling is what makes cooling harder on earth. The bigger the data center, the more difficult the cooling. This comes not just from the engineering challenges but also the political challenges from communities rejecting huge data centers, taxes, etc.
However, we haven't built anything larger than the ISS for radiators. We have a lot still to discover, such as micrometeorites puncturing fluid lines. I wouldn't bet on space data center, but Musk isn't making simple errors by thinking that space is "cold" instead of "insulated".

내가 일본가기 전부터 지금까지 한일 트위터 반말 존댓말 논란이 아직도 안 끝나던데... 그거 보고 궁금한 거 생김.
이렇게 츠키시마가 코이토한테 한번씩 반말하는 부분들
한국인은 반말과 존댓말을 판단할 때 나이 차이를 중요하게 여기는 문화니까.
츠키시마가 코이토보다 13살이나 연상이라, 계급으로는 코이토가 상관이지만 다급한 상황에서 무의식적으로 반말이 튀어나온 것이라고 생각했음.
츠키시마가 코이토를 상관으로 대하면서도, 한편으로는 아직 자기보다 한참 어린 미숙한 젊은이로 인식하는 걸 은연중에 드러낸 장면이라고 생각했고.
이렇게 생각했는데
일본에서는 그게 아닌거야? 상관이지만 저 상황에 반말이 전혀 어색하지 않은 거? 아니면 오히려 위화감이 심한거? 어느쪽인거?
これはなるほど素晴らしい。
