Nothing new under the sun?

Nokia may be losing the smartphone battle but it continues to make the running in developing countries. And maybe for tree huggers too. The handset maker has devised the Nokia Bicycle Charger Kit – a charger and dynamo and a holder to secure the phone to the bike. Get pedalling and the dynamo uses the movement of the wheels …
Busch+Mueller already sells a kit that lets you charge aa batteries in their (quite good) bike headlight, so it shouldn't be difficult to adapt that to mobile phones.
I have a bottle dynamo on my bike and frankly, I really should get around to replace it with something better. Yes, they're fairly cheap, but yes, they're more nuisance than they're worth. Why are we still using the fscking things?
A friend of mine has a dynamo in the hub of his front wheel providing regulated 5V power via a USB socket. He used it over the just ended summer to keep his iPhone 3GS charged while he bicycled 4000 km around New Zealand. The iPhone was recording GPS coordinates continuously (and uploading to RunKeeper.com) as well as being used as a still and movie camera (uploaded to twitpic and flickr) and everything else you'd expect to do with your phone.
