Electricity Without Wires, Using Magnets
According to new findings presented at the Oxford TED Global Conference, electricity can be possible without wires. Eric Giler of Witricity made his case with a presentation of a device that offers wireless electricity by making use of magnetic fields – rather than electrical fields – and wave frequency resonance to convey power via the open air.
As BBC News explained in its report, the technique just uses simple physics to charge a number of electronic devices across a specific distance. In the presentation Giler gave, he used batteries from the Google G1 and Apple iPhone to demonstrate. The iPhone proved to be the least responsive of the two, however the G1 was able to achieve a charge. This experiment alone could be huge for the future of energy as people look to save on their energy bills.
This technology, should it develop, could potentially save on the use of expensive cables and billions of single-use batteries. In addition, since this technology uses only magnets, it can theoretically eliminate any safety concerns associated with airborne electricity.
