Ride your bike, charge your cell phone

I just saw this on the CNET blog Green Tech, a cell phone charger that works while you're riding your bike.

It's from Nokia and costs $18. You have to ride at least 4 miles per hour for it to work. It's available online and will be in stores by year's end, the blog says.

It follows Motorola and Dahon in coming out with bike chargers. But Nokia is the world's largest cell phone maker, so this ought to reach a lot more people.

According to the company, the Nokia Bicycle Charger Kit contains a charger, a holder and a dynamo, or a small electric generator that uses the movement of the wheels to charge the handset through the standard 2mm charging jack used in most Nokia phones.

"Bicycles are the most widespread means of transport in many markets around the world, so this is just one more benefit to be gained from an activity people are already doing. This is a great solution to a real challenge, whether people will use it due to limited access to electricity, or to be more environmentally responsible," Nokia says.

Think this could work? Would you have one charger for the house, one for the car and one for the bike?
