Just to talk in international units to include everyone: I was under the impression it was supposed to operate at 1 mbar or 1/1000th of an atmosphere. That’s into the transition between viscious and molecular flow iirc (for air at normal temps anyway). You’re probably still pumping down with something like a scroll pump but it’s not very efficient anymore.
Thinking about the number of opportunies for leaks. Every joint, every screw, every pump connection. How they all shift against each other as the sun warms and cools them, how you relieve the strain without introducing pourous materials. It’s a fucking nightmare, and even if you manage all that you need to be pumping on it every few meters 24/7 to keep pressures that low with the realistic amount of leaks/in order to be able to pump down the local area where one occurs.
Like imagine if you needed a phat motor on every block to make roads work. The infrastructure demand is just unreal
