Wireless energy transfer, also known as wireless energy transmission, is the process that takes place in any system where electromagnetic energy is transmitted from a power source (such as a Tesla coil) to an electrical load, without interconnecting wires. Wireless transmission is employed in cases where interconnecting wires are inconvenient, hazardous, or impossible. Though the physics can be similar (pending on the type of wave used), there is a distinction from electromagnetic transmission for the purpose of transferring information (radio), where the amount of power transmitted is only important when it affects the integrity of the signal.

"Two coils with a matched resonance at the exact matching frequency on both ends = wireless power."



Wireless technology goes back to Tesla's experiments in Colorado in the early 1900s.

When Tesla died, the government took all of his papers and classified them. They did return most of those papers to Tesla's country of birth, but it would appear that the U.S. Government withheld some of those papers to hide certain technology from the public.

Wireless transmission of electricity, Tesla style, would have circumvented the metering of energy, abundantly available. That is why J.P. Morgan took the financing away from Tesla when he was building the Wardenclyffe tower on Long Island to supply wireless power to the world.
