To put it plainly. if a law of physics is absolutely correct then it cannot be broken, but all laws are subject to experimental verification so we can't be sure they are absolutely correct.
Theory tells us that energy conservation holds perfectly in all our standard models including electrodynamics, nuclear forces and gravity. Furthermore it holds even for ...

The problem is that neither the potential energy nor the energy necessary to compress the gas is of any importance here. We can set the energy of the compression to zero and still would not gain any energy in this model! So for any real device with losses we certainly can't gain energy.
This can best be shown in an experiment by connecting a propeller to a ...
