Wind envoy / A kind of Bicycle lamp

This is a conceptual design.This product is a bicycle light powered by wind energy. The cross-ventilation by bicycle driving transforms the wind energy into electric energy which can be stored and used during the nighttime. In that way, riding a bicycle becomes a part of improving the relationship between human and nature. The intensity of the light can be adjusted. There is a hidden USB interface on the back of the light. So users can charge the light when needed.
