Japan's taxis fit wind-powered cellphone chargers

We've come across Tokyo taxis with cellphone chargers before (hell, we've come across taxis here that are fitted with most things), but Kyoto taxi company Ecolo21 are playing up their planet-friendly image by fitting the roof-mounted lights on their fleet with miniature wind-powered generators that you can use to charge your cellphone in the back seat. There are only two minor flaws in their otherwise laudable plan; one, the generator charges directly so you only get juice while the fan on the roof is spinning, and two…they've only fitted out one car so far. They do promise to introduce a version that charges a battery and to fit them to more of the fleet in future, however.
