The wind powered bike light is a new concept which was designed by Hsieh Jung-Ya. The device is powered by wind as you ride your bike. This in turn charges a lithium battery which then poweres the 1700 lux LED. This covers the problem of the lights going out when you come to a stand still. The idea won an award recently and could be out soon although no official details have been given about that.
