Wireless power system shown off

A system that can deliver power to devices without the need for wires has been shown off at a hi-tech conference.
The technique exploits simple physics and can be used to charge a range of electronic devices over many metres.
Eric Giler, chief executive of US firm Witricity, showed mobile phones and televisions charging wirelessly at the TED Global conference in Oxford.

Imagine a future in which wireless electricity makes everyday products more convenient, reliable, and environmentally friendly.

WiTricity Corp.’s vision is to develop a family of wireless electric power components that will enable OEM’s in a broad range of industries and applications to make their products truly “wireless.” Wireless electric power delivered over room scale distances, and with high efficiency. Wireless electric power that is safe for people and animals. Wireless electric power—imagine no more… it’s here!

WiTricity Technology: The Basics

WiTricity Prototype System

This WiTricity prototype system demonstrates wireless powering of an LCD TV. In this demonstration system, a WiTricity power source is positioned on the floor. It is connected to AC power and converts AC current to an oscillating magnetic field. The WiTricity capture device (to the right of the LCD TV), converts the magnetic energy to alternating current and powers the LCD TV. The WiTricity power source and capture devices are highly resonant magnetic systems that can exchange energy in a very efficient manner. WiTricity Corp. is miniaturizing and packaging the technology so that it can be built directly into a wide variety of products and systems—with no need for an external power capture device as shown in this prototype configuration.

Looking for an exciting challenge, as well as a way to try and create easy and affordable access to space? The 2008 Space Elevator Beam Power Challenge has been announced by The Spaceward Foundation, and competitors have the chance at a $2 million top prize. And don’t think the picture included here is complete science fiction. Meteor Crater in Arizona is one of the sites being considered for the competition, which consists of climbing a vertically suspended tether using power beaming technology.

The Beam Power Challenge event is tentatively set for September 8, 2008. The objectives for the 2008 competition are climbing a tether 1 kilometer in height, at 5 meters per second minimum speed, for a prize level of $2M.
