Now that's an interesting question that is difficult to answer fully! --[[User:Aschlafly|Aschlafly]] 19:05, 1 January 2007 (EST)

Theoretically it is possible (the first law of motion), but practically it is impossible just because you wouldn't be able to eliminate all outside forces.
I also have a comment on your proof using the 2nd law of thermodynamics:
''"The only argument that a perpetual motion machine is impossible is based on an interpretation of the [[Second Law of Thermodynamics]]. If entropy is always increasing, even in closed (and isolated) systems, then indefinite motion is impossible because an increase in the disorder of the system will inevitably disrupt the motion"''
Firstly, as Dpbsmith has demonstrated, this is not the only argument against perpetual motion.
Secondly, though it is ''almost'' inevitable that increaced disorder will disrupt motion, it still isn't logically proven; it is always possible that it might go on just a little bit longer.
