Wireless Power Consortium Pushes for "Qi" Standard
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."
...for those that don't want to read the summary but may wish to discuss it intelligently in person.
There. Fixed that for you.
This is definitely a step in the right direction. I know it's really frustrating looking for a non-standard plug for my phone. I'm sure the days of searching for the right power adapter are limited.
5 watts is not a lot of energy. It's not like it is an induction cook top and you are a ferrous pan or anything. :-)
Kind of like the corruption of the Elves into Orcs in LOTR, the idea of charging the air with yet more EM pollution and calling it "Qi" makes a sick mockery of the real thing.
And there's a frickin' pyramid with an eye ball on the dollar bill.
We're being laughed at even as we are mutilated and enslaved.
Cue the conceited, ill-informed rationalizations.

Actually, when this becomes real a tinfoil hat may be the very last thing you'd want to wear. I'm assuming this is sort of like what happens if you go near really high capacity power lines with a flouescent bulb, where the power in the air is enough to cause the bulb to light. It's also enough that having lived near one long enough I can attest that metal isn't fun to wear near one.

I can charge ten things with one plate. Epic win.
Will Nintendo adopt it? Because I want a Qi Wii. And assemble it in Finland so the factory's website will be QiWii.fi

Anyway, why spell it "Qi" when the Chinese/Japanese language does not use the Latin script ?
Because "Qi" is sexy-looking and just begs for an elegant logo. "Chee" looks horrible and cheap.
Once again, you demonstrate why technology nerds should never be allowed to name any product or technology.
... and then they built the supercollider.
It's called pinyin and is the standard romanisation of Chinese characters. It is used in China and therefore they DO use the "latin script".
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)

*Slashdot really needs to move into the modern era with support for international unicode characters...
Great. Now whenever I see 'qi' I'll mentally pronounce it as 'aieee! *pound*'
Rampant carbon sequestration destroyed the Dinosaurs' tropical paradise. I'm here to help repair the damage.
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.
