Witricity shows off wireless electricity technology

Posted on Friday, July 24 2009 @ 22:14:08 CEST by

A company named Witricity has shown off a system that can deliver wireless power to a range of electronic devices over many metres. Witricity CEO Eric Giler claims the technology, which is based on the resonance of low frequency electromagnetic waves, could replace miles of expensive power cables and billions of disposable batteries.
Eric Giler, chief executive of US firm Witricity, showed mobile phones and televisions charging wirelessly at the TED Global conference in Oxford.

He said the system could replace the miles of expensive power cables and billions of disposable batteries.

"There is something like 40 billion disposable batteries built every year for power that, generally speaking, is used within a few inches or feet of where there is very inexpensive power," he said.

Trillions of dollars, he said, had also been invested building an infrastructure of wires "to get power from where it is created to where it is used."
