Prototypes of inventions that use novel combinations of resonance, magnetism, states of matter, certain geometries or inward swirling motion to unlock the secrets of universal energy have already been built. They provide proof of new or rediscovered principles. In many variations of these inventions, a small input triggers a disproportionately large output of useable power.""These energy converters don't violate any laws of physics if they simply tap into a previously unrecognized source of power - background space. A flow of energy from that source can continue day and night, whether or not the sun shines or the wind blows.
