Wireless Power Consortium Pushes for "Qi" Standard 189
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."

Qi, as in the Chinese romanization of æ£.
This is the same "qi" as Taichi's 'chi'. The life energy
It's the same 'chi' as the japanese 'Ki' æ-- as in "Tenki" (weather)

I forsee Witricity adapters and a slew of 3rd party knock-off components for home and travel that allow us to bathe ourselves in a continuous blanket of electromagnetic radiation 24 hours a day.
Sorry to tell you, but that's already happening from sources such as:

Anyway, why spell it "Qi" when the Chinese/Japanese language does not use the Latin script ?
Because Qi is the Pinyin transliteration, and Pinyin is pretty much as close as you can get to standard. Chinese and Japanese don't use the Latin script but there most certainly do exist standards to transcribe them consistently.
It gets a little hairy with Chinese, but that's how you write it and is sexier than both "Chee" and "Chi" (the now-outmoded Wade-Giles way of transliterating it).

I swore never to buy another phone with the same system, then I saw the W880i (damn you, Sony, for making such a slim sexy phone!) and now two years later I'm having the same issue.

Comparing the peak power of GSM to average power of this system is misleading at best (gsm transmits only 1/8 of the time due to TDM) and a lie at worst (GSM power control almost always pushes the level 10-20dB below that).
Then 2W max is on 850/900MHz, 1800/1900 has max 1W.
