I'd be very disappointed if people started making clothes generate static on purpose.
I don't know what the idea is of making pocket-sized devices bigger, even marginally, by attaching a wireless charging adapter. (I'm joking, the idea is, as always, MONEY) My cell phone and PDA just have mini-USB ports sticking out the side, so any adapter would be totally useless.
A hand crank would be really nice, if I was stranded somewhere with a dead car and dying cell phone.
Someone made one of those for DS. It actually worked, though it didn't provide enough charge to be useful. There's a Youtube video floating around somewhere.
