In a world where everybody is trying to go green, how do we minimize the amount of energy spent to power the street lights the light up the roadside? TAK’s wind-powered Turbine Light aims to tackle that issue by using the moving air from cars that zip past it on the highway to generate energy to power it. Of course, the first question everybody will ask is whether that amount of wind will be enough to power the lighting? Whatever the challenge, if they do manage to get it up and running, it will have a huge potential to save a lot of money in wind-heavy regions. The Turbine Light is an entry to the Greener Gadgets Competition, so if you want to see what the folks are envisioning for the future, check it out.
