This is the proposal of Eric Giler, CEO of WiTricity, when demonstrating last Thursday, at the TED Global conference, that it is possible to recharge the battery of the iPhone without using wires with technology from his own company. According to him, "you won't have to worry about connecting these things again". Be the paradise?

While explaining the possibilities offered by the technology, Giler demonstrated how it was possible to recharge the battery of an iPhone, a T-Mobile G1 and power a flat-screen TV. His dream is to see the idea replacing the current infrastructure in the future, which involves countless kilometers of power cables and alkaline batteries.
The technology is based on research by Marin Soljacic, a physical researcher at the Massachusetts Institute of Technology (MIT), and uses low-frequency electromagnetic resonance waves to transfer the energy from the source to the device through a coil at each end, which uses the same frequency allowing the power cycle to turn into enough voltage to power the gadget.
As the transfer takes place through magnetic fields, there is no danger or interference with other devices. In the demonstration with the iPhone, it was necessary to put the device in an extra case, since Apple does not allow additional parts to be inserted so easily.
As soon as the forecast of about 18 months is commercially viable, this could be one of the most desired solutions by current owners of iPhones, who daily complain about the consumption and duration of current batteries. Check out a Giler interview below BBC:
But WiTricity is not alone in this race: Intel is another company that invests heavily in wireless charging solutions. wait to see who will be able to deliver the best cost / benefit ratio for this alternative to cables.
