in Innovative wireless light switch could cut house wiring costs in half, a direct reply to the story

I found some on/off switches on Amazon that appears to use the motion of your hand pressing the switch to generate the power to transmit. It makes a fairly loud CLICK when you press it, so I assume it's some sort of piezoelectric mechanism?
