Quote from CT10Gov:
This guy believes in perpetual motion machines (suppressed by the gov, of course).
Over unity devices typically pull in heat from the ambient environment, so they are not free energy devices, as many would suspect (and quickly dismiss).
I graduated 3.32 mechanical engineering, suffered thru all the thermo classes and had all the over unity device debates with my professors, who, later, reluctantly conceded to my point that .....
the key to these devices is using an inverted population as the working fluid in the heat cycle.
A common device that is only possible with an inverted population is the laser, which defeats the "second law of thermodynamics", just like these over unity generators, by creating a molecular check valve that essentially takes in disordered energy and releases more highly ordered energy by limiting degrees of freedom.
Again, ask your local physics guru or look it up yourself if you don't believe. It's all out there.
