Bike For Battery!

Nokia just unveiled four inexpensive cellphones for developing nations and a new Bicycle Charger Kit for their line. The device is connected to the wheel via a little bottle dynamo, which generates energy from the pedaling. The device starts working at 4mph and at 7.5mph, the phone could be charging at the same rate as a regular plugged-in charger. Spend ten minutes at 6mph will charge the phone for 28 minutes of talk time or 37 hours of idle time. More details on the device available here.
This would surely be a convenient device for all you cyclists and bike commuters! Now if only someone would make this for the iPhone, the iPod, the Blackberry, and digital cameras...
