Wind-Powered Cell Phone Chargers in Japanese Taxis

Alright, so far only one taxi in Kyoto. Seems they stuck a wind-powered generator on the roof lights so you can charge your phone with alternative power while you ride. The practicalities haven’t quite been worked out: there’s no battery to hold the charge, so the system only works when the wind fan is actually moving. And the turbine could increase drag by a small degree, and hence increase fuel consumption. Yeah, it’d probably make more sense to charge off the car’s power, but it’s small ideas like this—ideas that are begging for refinement—that give us hope for a green future.
