Wireless Power Transmission
ABSTRACT:
Transmission or distribution of 5o Hz or 60 Hz electrical energy from the generating point to the consumers’ end without any physical wire has yet to as a familiar and viable technology.
This paper focuses on the past and future possible advancements in WPT and explaining why it has still not come into practical utility.
Wireless energy transfer has been around for about a century, but as of yet has only found usage in things like electric toothbrush rechargers and specialty applications such as beaming solar power down from space.
A simple demonstration of it can be constructed at home with ordinary materials. A loop of wire short circuiting a battery will cause a compass needle placed near it to point, and by tapping one end of the wire on and off of its electrode you can cause the needle to twitch. The transverse magnetic field induced in the line acts on the compass, performing work without the use of a physical connection.-
History:
As the wireless art developed during the turn of the 20th century, industry was looking toward a method of wireless energy transfer. Some of the then scientists are
Hertz: A precursor of this technology can be found in the works of Heinrich Rudolf Hertz in the late nineteenth century. In 1888, Hertz experimented with pulsed power transmission at 500 megahertz.
Tesla: Tesla was able to light gas discharge lamps, he lit ordinary incandescent lamps at full candle-power by currents induced in a local loop consisting of a single wire forming a square of fifty feet each side, which includes the lamps, and which was at a distance of one-hundred feet from the primary circuit energized by the oscillator.
Yagi: In Japan, Hidetsugu Yagi attempted wireless power transmission. In February 1926. Yagi managed to demonstrate a proof of concept, but the engineering problems proved to be more onerous than conventional systems.
The Need for a Wireless System of Energy Transmission:
A great concern has been voiced in recent years
