Looks like I may have to redesign the whole thing. My problem is the first step: breaking down water into hydrogen and oxygen. The result is eight tons of oxygen for every ton of hydrogen. I see this as two standard and two small tanks for oxygen, one small tank for hydrogen, a standard mining system, two small refineries (LOH, CH4), a small fission reactor (powers one refinery at a time), a regular methane tank and a regular fission reactor (powers the mine). The H2 and O2 tanks take 30 hours to fill while the methane tank takes ten.
That takes care of the bottom section. I think I'll leave the top level much the same and work on the middle one tomorrow.
