- Okay, I'll give it a shot.
-
- Given the assumption that we want to build large structures in space
- and on other planets, It seems that the mining of minerals in space for
- use in space would be profitable because of the huge gravity hole that
- you have to haul the stuff out of. If we want to do any large scale
- construction in space I would think the materials would have to come
- from space if we want to build anything for a reasonable price.
-
- Another interesting point might be that new mining techniques for "off world"
- mining might prove useful in squeezing more out of currently unproductive
- mines on earth.
-
- Of course why we would want to build any large scale construction in space in
- the first place is an entirely different discussion.
