By whom was it first introduced?
Wireless Power transfer was first demonstrated by Nikola Tesla in the 1890s.
How does wireless power work?
The basics of wireless power involves the transmission of energy from a transmitter to a receiver via an oscillating magnetic field.
To achieve this, Direct Current (DC) supplied by a power source, is converted into high frequency Alternating Current (AC) by specially designed electronics built into the transmitter.
The alternating current energizes a copper wire coil in the transmitter, which generates a magnetic field. Once a second (receiver) coil is placed within proximity of the magnetic field, the field can induce an alternating current in the receiving coil.
Electronics in the receiving device then converts the alternating current back into direct current, which becomes usable power.

How does wireless transmission create a sustainable environment?
Wireless power could reduce demand for power cables while making gadgets more durable, eliminate the need for throwaway batteries, and perhaps even accelerate the adoption of electric cars. Normal cars working on gas, emit pollutants in the air causing many long-term problems. Electric or hybrid cars can be charged all along the way it is going, there may be no limits of travel using these vehicles without the emission of harmful substances in the environment.
