You can recharge your mobile phone while you peddle your push-bike. According to the Smart Planet website, O2 has revealed a new mobile phone battery charger. In fact, they will be showing the device at the O2 Wireless Festival in Hyde Park, London from 3rd to 6th July. The company will be displaying an array of the new chargers attached to bikes for you to try - although the cycles will be fixed to the ground but you'll be able to get the general idea. You can plug in your own phone and peddle away to recharge your mobile, if you wish.
However, don't get too carried away with the idea. The bike-based charger is not, yet, due for general release. The device is only being shown at the show to bolster O2's green credentials. They've obviously seen Oranges' wind/solar powered tent at Glastonbury, then.
However, once the bike-based charger is in the wild, surely it can only be a matter of time before O2 does the decent thing and release the thing for general sale?
