Might this be incentive for teenagers who have their phone plastered to their ear, or fingers clickety-clicking text messages on a tiny keyboard, for 18 hours a day?
Nokia is introducing a cell-phone charger that's driven off the front wheel. (It uses the well-established technology of a dynamo in contact with the front tire, like generator-lights.) Ten minutes of cycling is supposed to be good for 28 minutes of yakkin'.
It's being introduced next month in India. One reviewer observes that the cost is "a good chunk of what an average bicycle costs here," so it might not catch on.
I had a couple generator-lights as a kid, and never cared much for them. For one thing, I didn't like the noise and resistance of the thing rubbing against the tire. And at least back in those days, if you stopped, so did your light. If they had a capacitor or a battery in the circuit, maybe that problem could be overcome, particularly in this day and age of low-power LEDs.
Also, I'm not very comfortable with the little look-down-at-it phone bracket. Another distraction.
A detailed spec sheet (PDF) fpr the phone charger can be seen HERE, should you be interested. From the text (English from some other language?): "Fun to Use - Blaster music from the mobile phone while bicycling and charging."
