What is WiTricity?

In 1899, Sir Nikola Tesla enlighten 200 lamps at the distance of 40 km.

But only 15% efficiency was achieved.

Background

(1/2)

MIT powered 60 watt light bulb from 2 meters (7 ft) at 40% efficiency

First practical example

of WiTricity.

(2/2)

Working Principle One Simple Physics Rule !At Source : Electricity Magnetic Wave At Device : Magnetic Wave ElectricityResonant coupling

(1/1)

Is it secure ???Works on the principle of magnetic

induction.Interact weakly with surrounding objects

(biological tissue)

(1/1)

Applications

Automatic wireless charging of mobile electronics

(1/5)

Direct wireless powering of stationary devices

Sony demonstrated its wirelessly powered television [2010 October]

Demonstration of WiTricity on cell phone and LCD at the TED conference

(2/5)

Direct wireless powering of PC peripherals

(3/5)

Automatic wireless charging for electric vehicles

(4/5)

One source is able to transfer the energy for the electronic devices.

(5/5)

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.
