Nokia has announced a bicycle-powered mobile phone charger. Although it's not a new idea – we reported on a Kenyan bike-powered project last summer – it's a first for the manufacturer, which is aiming the device at developing markets where access to electricity can be limited.
A 10-minute ride will produce enough power for around half-an-hour of conversation. The charger uses a dynamo to produce the power, with a handlebar mount holding the phone in place. It's expected to be available later this year.
