This may be feasible as a long term solution, but how do you bootstrap the energy-intensive process of extracting and purifying aluminum in the first place?

- credit_guy 5y agoYou can bring let's say 100 tons of aluminum from Earth. At an energy density of 1.3 MWh/ton [1], you'd have 130 MWh of storage. And since there are 336 hours in the lunar night of 14 days, that corresponds to a power capacity of about 0.4 MW, which should be fairly decent for the bootstrap period.
