Wireless electricity may soon power cell phones, cars and even heart pumps

The chief technology officer of WiTricity told CNN that they are going to transfer power without any kinds of wire, its going to be completely wireless. A team of MIT professors then developed what they call " resonant power transfer," in which a power coil is able to wirelessly transfer electricity to another device containing a similar coil set to the same frequency. They not actually putting electricity in the air. What they are doing is putting a magnetic field in the air. When you bring a device into that magnetic field, it induces a current in the device, and by that you're able to transfer power. Wireless electricity is widely considered to be safe, but WiTricity and other companies developing similar technology are still trying to find effective ways to efficiently transfer electricity over longer distances. Giles says that if the hurdle of transferring electricity over greater physical distances can be crossed, then wireless electricity would quickly replace the world of cables. And after the technology is in place, manufacturers would then have to install the equipment allowing for the wireless electric transfer to take place. It would not only free up literal space but could potentially reduce pollution, eliminating the need for disposable batteries.
