Perpetual Motion.....?

Now I'm not saying this is a perpetual motion machine (as this would violate the first or second law of thermodynamics) but...isn't it thrilling to consider a future in a machine could work indefinitely without an energy source?

Let's be frank: lots of things that were considered impossible in earlier ages are now possible. Who knows, perhaps a perpetual motion machine will one day not be hypothetical. Maybe the first and second law of thermodynamics are not immutable and could one day be considered variables due to a discovery of new laws of which we are as yet unaware.
