- This is not a particularly big deal. Water, being hydrogen oxide, can
- be formed from hydrogen and any source of oxygen. There was a recent
- posting to the effect that some elements in moonrock are in a relatively
- high oxidation state, so it's no surprise that you get some kind of reaction
- with hydrogen under mild conditions. If you really up the temperature you can
- extract almost all the oxygen from minerals using hydrogen, except for
- the part locked up in silicates. The result is metal (useful), water
- (if you don't throw it away as steam) and slag.
-
- Since water is a valuable commodity on the moon, but hydrogen is scarce,
- there's interest in taking hydrogen there and using it to make the
- water for bases. Since hydrogen represents only 11% of the mass of
- the equivalent of water, it makes sense to ship that instead. The only
- question was, how easy is the trick? The answer seems to be: pretty easy.
