ORIGINAL: BlueTemplar Please do add, a couple months old is a very short time as forums go ! Well, the main issue with airless moons is that (conventional) firearms and diesel engines shouldn't be able to work either... Common misconception! Conventional firearms will work OK in vacuum, with one or two caveats; you need to use nonstandard lubricants and less propellant. The stuff we use down here on Earth will boil off into a sticky mess, which is the opposite of lubricating. You would need to use something with less kick, but that would be a benefit as you'd also need less propellant for the same oomph. Source; the US army did research into this in the 60s for obvious reasons. Project Rho has some stuff about it, you can also look up the unclassified document "The Meanderings of a Weapon Oriented Mind When Applied in a Vacuum Such as the Moon", U.S. Army Weapons Command, Directorate of R&D, Future Weapons Office, June 1965. I'd link directly, but account's too new. Now, diesel engines I'll give you. Lower-tech electric engines as already-proposed are the obvious solution here.
