Seo Master present to you:
A mobile phone or laptop , that will charge wirelessly , in your pocket or wherever you are roaming . A TV or a printer which will not take wire for electricity. Where ever you want, you can switch them on and can enjoy their service.
Seems to be amazing without wire! US Scientist has made the technology and just waiting to apply in daily life.
WiTricity , A company from Massachusetts Institute of Technology (MIT),Boston, has innovate the device of charging without the electric cable / wire.
Regular charging device or wired electricity uses electromagnetic induction to transmit the power. Through electromagnetic induction, an electric current is sent through a magnetic field generated by a power conductor to a smaller magnetic field generated by a receiving device.
But on other hand WiTricity devices share energy through magnetic fields as well which is wireless and can penetrate the concrete also. WiTricity's devices produce magnetic fields through a process called resonant magnetic coupling, which allows power to be transmitted several meters in distance.
As examples. A child pumps her legs at the resonant frequency of a swing to fly through the air, or an opera singer shatters a wine glass by singing a single note at a frequency that matches the acoustic resonance of the glass.
Now this works only in short distance because the device is still not that strong . But the. WiTricity company has announced that , the day is not so far when this wire will be a history. A house can get full energy from a single device , cars are running on road can get energy from those device .
