New Charger Harvests Energy from Wi-Fi Signals
RCA recently showcased a new charging product called the Airnergy Charger that collects Wi-Fi signals, converts them to electricity, and uses that electricity to power a small internal battery. The charger can then be plugged into a device such as a mobile phone via USB and provide it with a charge. The device is always on and collecting Wi-Fi signals, so it is always charging (when near Wi-Fi hot spots). According to RCA, the Airnergy Charger will be available by summer 2010 with a retail cost of about $40.

I'm sure there are plenty of pros and cons, but...
Will it fry your brain
No thanks. This sounds like a terrible idea. 😕
but if they make wi-fi hotspots more efficient... / billing?

So if there's all this excess energy in the air, should it simply be curtailed, or harnessed? If it's harnessed for wireless battery charging, the next logical question is who pays? Do we need a billing standard? Could you choose to charge your phone just by sitting in a Starbucks, and have the electricity cost billed to your Starbucks card? (Or AT&T bill?)
Gosh, this sounds like such cool Star...
So it won't power laptops? and...
Will it slow down the network?
If so wouldn't/shouldn't that require a wap/wep key? 🤨
