Concept of collecting solar power in outer space by solar power satellites (SPS) and distributing it to Earth.
Since wires extending from Earth's surface to an orbiting satellite are not feasible with current technology, SBSP designs generally include the wireless power transmission with its concomitant conversion inefficiencies, as well as land use concerns for the necessary antenna stations to receive the energy at Earth's surface.
Inductive charging (also known as wireless charging or cordless charging) is a type of wireless power transfer.
Tendency of an electrical conductor to oppose a change in the electric current flowing through it.
Stongly-coupled self-resonant coils can be used for wireless power transfer between devices in the mid range distances (up to two metres).
Performed using direct induction heating of cooking vessels, rather than relying on indirect radiation, convection, or thermal conduction.
The resulting oscillating magnetic field wirelessly induces an electrical current in the vessel.
In electrical engineering, two conductors are said to be inductively coupled or magnetically coupled when they are configured in a way such that change in current through one wire induces a voltage across the ends of the other wire through electromagnetic induction.
Wireless power transfer
Form of electromagnetic radiation with wavelengths ranging from about one meter to one millimeter corresponding to frequencies between 300 MHz and 300 GHz respectively.
Microwaves can be used to transmit power over long distances, and post-World War 2 research was done to examine possibilities.
Serbian-American inventor, electrical engineer, mechanical engineer, and futurist best known for his contributions to the design of the modern alternating current (AC) electricity supply system.
From the 1890s through 1906, Tesla spent a great deal of his time and fortune on a series of projects trying to develop the transmission of electrical power without wires.
Electrical resonant transformer circuit designed by inventor Nikola Tesla in 1891.
Tesla used these circuits to conduct innovative experiments in electrical lighting, phosphorescence, X-ray generation, high frequency alternating current phenomena, electrotherapy, and the transmission of electrical energy without wires.
The ISM radio bands are portions of the radio spectrum reserved internationally for industrial, scientific and medical (ISM) purposes, excluding applications in telecommunications.
Long-distance wireless power systems have been proposed and experimented with which would use high-power transmitters and rectennas, in lieu of overhead transmission lines and underground cables, to send power to remote locations.
Transfer of electrical energy from one circuit to another, or between parts of a circuit.
