How about moving stuff _from_ the Moon back to Earth. Harvesting the Moon for rare materials is going to be relatively cheap.

- jacquesm 7y agoWhat rare materials would these be? The only thing that comes to mind at the surface would be Titanium but even there the economics would probably not make sense if your goal is to use the material on Earth.
- adhoc32 7y agoI have no idea. Just trying to make a point for the utility of the project. Maybe rare earth elements or something else yet to be discovered?
- MagnumOpus 7y ago> What rare materials would these be? Every material is rare outside of gravity wells. Even plain steel, aluminium or magnesium cost >$1000/kg if you want them delivered to geostationary orbit. So this material would not be for earthbased construction, it would be for space factories, space-based solar microwave powerplants, spaceships etc.
