CONCEPT OF WIRELESS ELECTRICITY (Wi-Tricity)
Our forefathers marveled at the invention of glowing light bulbs by Thomas Edison in 1879. However, to us 21st centurions, the light bulb is nothing out of the ordinary. When computers, cell phones, laptops, iPods, etc. were invented our antennas tweaked. Now this is what you call invention! However, as time's progressing we are getting used to these devices. In fact, charging all these appliances has become so very cumbersome. Each appliance has its own set of chargers, and with every family member owning their cell phones, the drawers are overflowing with all sorts of wires. How many times have you wished if there could be some way to do away with all the wiry clutter? When you are on the way to work and your cell phone beeps in hunger for power, haven't you wished for your cell phone battery to get 'self charged'. Well your plight has been heard by 'WiTricity'. One could imagine, world without wires! Wow! How possible? Why not? If cell phones and cordless phones can replace landlines, then why can't there be a possibility to replace power cables with WiTricity! WiTricity is nothing but wireless electricity. That is, the transmission of electrical energy from one object to another without the use of wires. It will ensure that the cell phones, 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 these devices won't require batteries to operate. Prof. Marin Soljacic from Massachusetts Institute of Technology (MIT) is the brain behind WiTricity. He proved that magnetic coupled resonance can be utilized in order to transfer energy without wires. 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...
