Historically, the first person who attempted to test the viability of wireless electricity was the Croatian-American engineer, Nikola Tesla (1856-1943). Although he was noted for his inventions of rotating magnetic field induction motor and successes commercializing the use of alternating current electricity, his experiments on wireless electricity (eliminating the conducting material between power source and end users) failed miserably. He died in abject poverty. Unbeknown to his practical engineering mentality are the theoretical facts of physics that different forms of energy can be transmitted in three different ways: by conduction, by convection, and by radiation. However, each holds a distinctively unique physical mechanism not found in the others. For conduction, this unique property is constant average speed of transport of charged particles (e.g. electrons). For convection, it is the existence of a constant thermal energy gradient as nonzero temperature differences. For radiation, it is constant energy transfers of particle collisions. Although all three mechanisms resulted in a final energy increase, only the convection mechanism allows a final energy decrease similar to cooling processes, which are in air conditioners and refrigerators. In this sense, the heat pumps can function both as a cooling or a heating unit.
Is there a fourth energy transfer mechanism? That is one that can extract energy directly from the quantum vacuum fluctuations of zero-point energies. Logically, this 4th mechanism is simply reverse convection, which transfers energy from a cold body to a hot body. But it would then violate both the zeroth and the second law of thermodynamics. Luckily, it does not violate the first and third law of thermodynamics. The first law simply states the conservation of total energy while the third law states that absolute zero of temperature can never be attained, which implies that infinite energy can be extracted, but harder and harder for each succeeding steps, from the cold vacuum to a warmer body.
