The Wireless Power Consortium (comprised of Samsung, Sanyo, Olympus, Philips, Texas Instruments, and others) has started a push towards a wireless charging standard under the moniker "Qi" (pronounced "chee"). "Members of the Wireless Power Consortium are reviewing version 0.95 of its technical specification which defines a proposed standard for charging devices, using up to 5Watts power, delivered by electromagnetic induction. The spec could evolve into a standard — and will be demonstrated by multiple vendors on September 15th to 16th. ... It is less ambitious than the system demonstrated this summer by Witricity, which operates at a distance of a few meters, using resonance, which the company claims has green benefits through replacing disposable batteries."
