What the article doesn’t say is that a resting human being requires about 2.73 Kg of oxygen per day, or about one tonne per year. So three one-metre tall reactors are required per lunar inhabitant. Therefore, each person inhabiting the lunar station requires the excavation of three tonnes of lunar rock per year, to provide enough oxygen to live.
2.73 Kg/day is the resting requirement. Oxygen requirements during exercise are about 15 times that. It could be argued that lunar explorers are going to be pretty active – so say, an average of five times rest requirement will require an excavation of 15 tonnes of lunar rock per person per year.
No problem, each person would only have to excavate 90.7 pounds of rock per day which is 11.34 lbs per hour. There would be at least a few hours available each day for other activities.
