Is that literally all there is to it -- minus reasonable loss? Does something like that already exist?
> i.e. some plants
Perfect! Do you think that plants can make up the loss from systems that we could set up for converting CO2 back to O2? When can fly some cows and chickens up there? Throwing plants and livestock on the Moon seems too good to be true.
Also, completely off topic, does anybody know the current value per acre of Moon?
- Sir_Cmpwn 11y agoThere isn't really O2 loss from the natural process of breathing. Leaks in the pressurized environment would probably be a much bigger source of atmosphere loss.
- ethbro 11y agoNot sure you're getting what parent said. Oxygen is an element. It doesn't get "used up" in the sense that you have less. It simply gets bound in different forms (like more complex molecules). It just takes energy to release it so we can breathe it again. No loss (unless you run it through a fusion reactor). Photosynthesis is one such process.
- Vendan 11y agoOne useful thing, not currently used due to space, weight, and power issues, most of which would be minimal issues on the moon, is the Bosch reaction. Basically, CO2 + H2 => C + H2O. Split the H2O(water), and you get back the H2 to reuse in the Bosch reaction, and breathable O2.
