passive regen for oxygen tanks

[Cyfarfod]

If you're just after AIR, not 02, then there's also the northern storage above the miniature medbay, as well as various canisters scattered throughout maint (check near the atmo hookups). This only applies to the cogmaps, on the other maps air supplies, IME, are much more difficult to come by.

This is a pretty cool idea, and so is the vending machine idea. Either sounds awesome to me.
