Green Noise is a cool concept that converts noises to electricity. The devices will be best used at airport runway which could then convert the sounds produced by airplanes and other engines to electricity to power the lights of the runway.
Green Noise is the concept by designer Hung-Uei Jou. It comes in the form of a conical speaker to endure the elements and the modular structure stands on tripod base for easy maintenance.
