Wire-free charging of: cell phones, gaming devices, PDA’s, handheld devices, wireless keyboards and wireless computer peripherals will soon be a reality.
A Pennsylvania-based company, Powercast, has developed a device that transmits low voltage electricity through the air. A transmitter plugs into a wall socket and transmits DC power over radio waves (RF) to an embedded receiver in the device. Currently devices within a few feet of the transmitter can be charged without messy wiring. The company has partnered with Phillips Electronics and will be launching a wireless LED light stick later this year. Other products like a wireless keyboard and mouse combo will roll-out in 2008.
A few features:
eliminates batteries – very green
more cost effective per watt than batteries – very green
eliminates power adapters & wires – reduces waste and clutter
allows powering-on as needed – saves energy
functions as backup power source
I need more information about this “A Buzz in the Air” device, what is the cost price for whole sale????
need bulk price.
Here is a good site explaing how it works.

Don’t be naive, just because it eliminates batteries doesn’t mean it’s green. A big part of the energy is wasted into radiation. Tranfer by cable is a far more efficient use of energy.
I took a look for the Tesla Wireless Power product at my local Radio Shack. No luck.
Tesla did this over 100 years ago. Why is this new and interesting?
Will these transmitters be always on? Judging from current AC/DC transformers, these devices will waste much more energy by being plugged in, than they will save during their brief intervals in use. But a very interesting technology to watch.
