- (Appropriate last name for such a question. :-) :-)

- -I've seen references in the past which suggest using Lunar O2 and Aluminum
- -as rocket fuels. Have there been any fairly detailed designs of how such
- -a beast would be constructed? Perhaps a hollow cylinder of packed Aluminum
- -dust into which LOX is pumped?
-
- Here's the only fairly solid reference I've come across. If you could
- contact the company and post some information, the readers of sci.space
- would be very grateful.
-
- An aluminum-oxygen engine could potentially be very useful for launch from
- the moon, since both materials are abundant there (and hydrogen is at best
- very rare, and therefore valuable). I expect the specific impulse isn't too
- great, but you don't need a very high specific impulse to escape from the
- moon.
