Wireless power nears final spec, testing

updated 05:50 pm EDT, Mon August 17, 2009

Wireless Power 0 95 Spec

The Wireless Power Consortium today signaled it was getting closer to a finished release by releasing the 0.95 spec for its standard. The advancement gives members of the recently-formed group enough to help test interoperation between their devices and others, which themselves are getting closer. A first formal test is expected in Eindhoven, The Netherlands at the next meeting of the group, which doesn't have a readily publicized date for the event.

The technology is intended primarily to eliminate the need for a power cable for handheld devices that consume 5W or less of power, particularly cameras, cellphones and portable media players. Current implementations usually involve putting devices on a contact plate that sends power through an induction-friendly portion of the hardware. Proprietary implementations have already existed for a short while and are highlighted by Palm's Touchstone cradle, which uses inductive charging to recharge the Pre at a slower rate than with wired power but with extra convenience.

    didn't Tesla demonstrate this technology about 80 years ago... although arguably it was better. free wireless energy - tapped from our earths natural fields.... wonder why the power companies didn't go for that ;)
