With one stomp of his foot, Zhong Lin Wang illuminates a thousand LED bulbs - with no batteries or power cord. The current comes from essentially the same source as that tiny spark that jumps from a fingertip to a doorknob when you walk across carpet on a cold, dry day. Wang and his research team have learned to harvest this power and put it to work.
