A taxi company in Japan offers passengers a way to charge their cell phones using electricity generated by a wind turbine mounted on a taxi's roof.
The taxi's rooftop wind turbine has a built-in generator so that wind energy is converted to electricity. The electricity is stored in the car's battery and then sent to a cigarette lighter socket. By connecting a charger to the socket, passengers can charge their cell phones. The company installed this system in one of its taxis, and it is planning to install an improved version in its remaining 19 taxis by the autumn of 2005.
A forward step towards a better environment. I wish more gadgets were as eco-conscious as these. Source: JapanFS.org
