Somebody forgot to mention health as a reason for going on such a station. The only micoorganisms one will have aboard such a craft is what is brought aboard it. So no flu season, no colds going around, no STDs if those are checked out before one boards, etc. Also, like the original writers said, there is really no reason why man cannot just 'live in space'. Artificial gravity might be a consideration, but a large enough ship complex and artificial gravity at some certain acceptable level should suffice. Breathing gasses should be recycleable as oxygen is mainly an energy transfer enabler in the body..you breathe in O2 and put out CO2, a bit down the energy hill. Reformers can take the CO2 and give back the O2 and the carbon black is a byproduct useful for many things. Carbon nanotubes for instance for constructing 'space tethers' down asteroidal gravity wells to facilitate mining operations. Standing Bear
