Here’s a concept: turn noise pollution into green power for lighting airstrips! The Green Noise concept design from designer Hung-Uei Jou aims to do just this, although how, exactly, isn’t all that clear.
According to the designer, the shape of the Green Noise is modeled on conical speakers, which allow it to easily absorb sound from take-offs and landings (somehow) while preventing rainwater from collecting on the bottom. The Green Noise features a display that lets technicians know how much power has been collected, apparently, along with how long until the internal, noise-powered light will need to be changed. When that time does arrive, the modular tripod design makes it easy to get at the burnt-out bulb.
While the idea is intriguing–part of a growing movement, it seems to capture energy expended in the most unlikely of places–this concept design suffers from a lack of technical data. If noise can indeed generate power, though, we’re sure that airports will be all over little gizmos like this in the future.
