WiTricity - Wireless Electricity
[attachment=18420]
What is WiTricity?
WiTricity is nothing but wireless electricity. Transmission of electrical
energy from one object to another without the use of wires is called
as WiTricity. WiTricity will ensure that the cellphones, laptops, iPods
and other power hungry devices get charged on their own, eliminating
the need of plugging them in. Even better, because of WiTricity some
of the devices won't require batteries to operate.
What's the Principle behind WiTricity?
WiTricity - Wireless Electricity, these words are simpler said than
done. The concept behind this fascinating term is a little complex.
However, if you want to understand it, try and picture what I state in
the next few lines. Consider two self resonating copper coils of same
resonating frequency with a diameter 20 inches each. One copper
wire is connected to the power source (WiTricity transmitter), while
the other copper wire is connected to the device (WiTricity Receiver).
The Brain behind WiTricity?
Prof. Marin Soljacic from Massachusetts Institute of Technology
(MIT), is the one who has proved that magnetic coupled resonance
can be utilized in order to transfer energy without wires. What's even
more interesting is how he came about this idea. Soljacic, just like
any of us was fed up of his 'low battery' beeping cellphone and wondered just like any of us if there was a way to get rid of this
'charging problem'. However, here is where the difference between
Soljacic and any of us comes in. He didn't just stand there wondering,
instead he tried to figure out if there existed any physical
phenomenon which could be of some help. He remembered Michael
Faraday's discovery of electromagnetic induction (1831) and used it
to come up with WiTricity.
MIT's Experiment:
In 2007, Marin Soljacic led a five member team of researchers at MIT
(funded by Army Research Office, National Science Foundation and
the Department of Energy) and experimentally demonstrated transfer
of electricity without the use of wires. These researchers were able to
light a 60W bulb from a source placed seven feet away, with
absolutely no physical contact between the bulb and the power
source.
