I wonder...

Last night I contemplated on the problem of perpetual motion machines. The laws of physics, as they are written currently, state that such machines will never run perpetually because they will eventually be overcome by resisting forces like gravity and friction. But if the same motor is used in a moving vehicle, wouldn't it be possible that the inertia and other forces encountered during motion might help "jumpstart" the machine to continue running?

Perhaps a generator based on the concept below could be used:

Here's another one
