OK, the picture clears yet more...
Sooo...
Hang on, I need to think a little more.
[please pause here for a few minutes]
So basically the energy that's passed to the air (to create the pressure waves) is non-existent in space. That's the general concensus I'm getting.
OK, well let me put up another hurdle (unless I've missed something obvious, which is very likely at this time of night...). The craft has say 100 units of energy, and loses 10 to the air/sound/pressure waves. So does it just simply hold those 10 units when it's in space? (As say Kinetic Energy for example.) I would asume it would.
