I usually lose interest as soon as I read "it doesn't work now but it will definately work in vacuum".
Anyway, it is probably impossible to create a perpetual motion machine as defined in the dictionary, but what if we could create a machine that appears to be perpetual? Not to trick people but to really use the machine to do useful work for us without requiring any energy source or fuel that we can see or know of. We should not assume that we have discovered or detected all possible energy sources that could be used for our benefit via a machine of some sort. There could be a lot more around us than we think. All we need to do is convert it to a usable form of energy for us and hope it will never run out.
