One of the biggest challenges for space colonists is just how expensive (in terms of energy) it is to get supplies off of planet earth. Until we get a space elevator, it's going to stay that way. One solution is to send as little as possible up there. When it comes to building a moon base, couldn't we just make it out of rock? After all, the moon is already made of rocks.
