We don't usually think of it this way, but noise is energy. What if we could harness the sound energy created by loud things? What if we could then use it to make them run better?
The Green Noise does just that, collecting the energy created by one of the loudest sounds around – airplane engines – then converting it to electricity used to power runway lights.
Imagined by Hung-Uei Jou, the Green Noise features a conical speaker-form designed to endure the elements a tripod base for easy maintenance.
