Definition of "Free Energy":
Free energy does not mean perpetual motion. By 'free energy,' we refer to energy systems that tap into inexhaustible, ubiquitous, and clean sources of energy generation, such as solar, wind, tide, and geothermal, but also non-conventional avenues such as zero point energy, radiant energy, cold fusion, and magnet motors. Extracting power from the vast sea of energy that surrounds us is no more perpetual motion than a photovoltaic cell. It does not violate the second law of thermodynamics. It is a conversion of energy from one form into another form that is usable -- not the creation of energy out of nothing.
