A Wireless System of Energy Transmission is being discussed to find its possibility in actual practices, their advantages, disadvantages and economical consideration. AThis paper by tanauj kumar mandal(tanujmandal[at]sify.com) mainly concentrated on :
i) The most popular concept known as Tesla Theory,
ii) ii) The microwave power transmission (MPT) called Solar power satellite, and
iii) iii) The highly efficient fibre lasers for wireless power transmission.
Tesla mastered this technology and was the first to try these experiments through Wardenclyffe Tower. The modern ideas are dominated by MPT(microwave power transmission).It has been proven that electrical energy can be propagated around the world between the surface of the Earth and the ionosphere at extreme low frequencies in what is known as the Schumann Cavity.Wireless power transmission is a feasible alternative to the extensive and costly grid of electrical transmission lines used today for electrical power distribution. It is Efficient:efficiency of the transmission can be as high as 96 or 97 per cent, and there are practically no losses.
Demerits
Biological Impact: The frequencies used may be harmful to biological beings.
Economic impacts: Initial investment is very high.
