The dark side of the moon light idea, kind of like what some of the
small cities do in Europe where they run reflectors up on top of that
mountain and they reflect light down into the valley so that they can
have sunlight instead of always being in the mountains shadow.
Build the base on the dark side of the moon and then build towers with
reflectors that could beam, reflect light down to the base and then
you can set them on a day and night cycle so that even though you're
on the dark side of the moon you still feel like you're getting a
sunrise and a sunset and you can maintain a certain circadian rhythm.
