On serious note isn’t there some type of future plan to put nuclear reactors on the moon in this decade?
In general these processes are energy intensive because they involve temperatures high enough to melt rock. On the Earth that is difficult to achieve because you need to keep the furnace hot. On the Moon with its hard vacuum, a large chunk of rock moved onto insulating material doesn’t radiate much heat. So all you’d need, really, is a large parabolic mirror. The Sun is your power source.
Generally speaking, it’s a high risk, low reward mode.
If you can figure out how to avoid creating dust clouds on the moon, which is not a small if, solar concentrators could provide a lot of the heat for the process, reducing the power needs to the electrochemical part.
