Pull-string charger eliminates the plug-in leash


charger

Charge your cellphone by pulling the string for one minute. Wow, you could do that on a desert island, in a flash mob, or anywhere if you left your cord at home. These are the details from silicon.com:

You can now use muscle power to charge your electronics. Easy Energy at CES 2010 showed off the YoGen hand charger, which is now available for $40. When you pull the string, it turns a mini flywheel that produces a steady stream of power – up to five watts – for small, portable devices. One minute of pulling is enough to charge a mobile phone, according to the company.

Easy Energy is adapting the same flywheel alternator technology for a pedal-powered laptop, called the YoGen MaxT, which is still under development.
