Assuming that in the future Empyrions space will be much bigger, we need possibility to produce oxygen amd maybe water in space while we are traveling through galaxy.
We could have a "green house", inside our CAPITAL vessels, with big leaves plants (herbs) that will in conjuction with O2 generator, produce oxygen. We could than have other maschine that could produce H2O from fruits or vegetables we plant for food....or recycle water from spoiled food...
