Stands for ‘wireless electricity’Eliminates the use of cables for
transmission of powerTransmission by induction through
resonators.Security
What is WiTricity?

In 1899, Sir Nikola Tesla enlighten 200 lamps at the distance of 40 km.
But only 15% efficiency was achieved.

MIT powered 60 watt light bulb from 2 meters (7 ft) at 40% efficiency
First practical example
of WiTricity.

LimitationsIt is a midrange technology.
(max 7.5 m)The maximum efficiency obtained in full
ideal conditions is 95% .Only obstructions are metal structures like
metal doors and metal walls.
