Solar panels need semiconductor-grade silicon, which you aren't going to find in nature anywhere. On the other hand, it's not enormously hard to make if you have the right equipment, and there are plenty of silicate rocks on the moon. > Also are the base chemicals around > that would be useful for making batteries (lead and H2SO4 type of battery or > lithium, or even better: nickel cadium). Lead, nickel, cadmium, maybe. The moon is badly short of hydrogen, and probably sulfur as well. Lithium is a rare metal anywhere, for quite fundamental reasons. Some other things the moon is short of are nitrogen and chlorine, by the way. Both of them rather important to life. One possibility, though, is that there may be frozen volatiles (water, etc.) in some of the lunar polar craters which contain areas that are permanently in shadow. A lunar polar orbiter with remote-sensing gear is what we need to settle this. -- Henry Spencer @ U of Toronto Zoology {allegra,ihnp4,linus,decvax}!utzoo!henry
