iYo: Would a yo-yo phone charger actually work?


There's no reason Peter Thuvander's "iYo" yo-yo-powered charger wouldn't work — except perhaps physics. He hasn't actually built one, but suspects that the motion of a yo-yo with a magnet inside would generate enough power to charge his iPhone or anything else that can sip power from a USB port.

Help me out: would this actually work at a rate that would be practical? I haven't the first idea of how to do the math.
