I found this new software app on the Internet that converts WiFi signals to electricity to charge your PDA, I understand the iPhone, iTouch applications will be in the AppStore shortly. I’m just having issues with using it with my old 802.11b access points, it doesn’t charge very well, but if I use on my new Belkin ‘N’ series, as you can see in the screenshot, it charges very fast. The only issue is my battery gets very hot, because it says it blast charges it, I think the instructions are not very well laid out, not written in good english. The software vendor WireFree A/S is appearing at Gadget Show 2010 Live next week on stand OZ56.
