Wireless power transfer (WPT; also wireless energy transmission or WET) is the transmission of electrical energy without wires as a physical link. In a wireless power transmission system, an electrically powered transmitter device generates a time-varying electromagnetic field that transmits power across space to a receiver device; the receiver ...
The Alliance For Wireless Power is an industry standard group that uses the principles of magnetic resonance to develop a wireless energy transfer system over distance. The WiPower system uses directed and controlled magnetic fields to replace traditional power cords. [ 1 ]

The Wireless Power Consortium was started by Fulton Innovation, a 100% subsidiary of Alticor, parent company of Amway. The original motivation was to power a portable water purifier, sold by Amway , called eSpring, for which the wireless power transfer technology called eCoupled was created.
Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer. It uses electromagnetic induction to provide electricity to portable devices. Inductive charging is also used in vehicles, power tools, electric toothbrushes, and medical devices.
The Wardenclyffe Power Plant prototype, intended by Nikola Tesla to be a "World Wireless" telecommunications facility.. The World Wireless System was a turn of the 20th century proposed telecommunications and electrical power delivery system designed by inventor Nikola Tesla based on his theories of using Earth and its atmosphere as electrical conductors.
