Somehow I'm a bit queasy about this business of "storing vacuum" in a
tank.
So I checked with the local supplier of industrial gases. If you need a
tank of compressed air, that's no problem. But a tankful of vacuum, er
that's not listed in the catalogue.
It seems the only way to maintain vacuum is to have a motor-driven
exhauster working all the time. That's how its done in the vacuum brake
system on trains.
