The battery casing in this bio battery is made from vegetable-based plastic and generates electricity using a sugar solution. It's powerful enough to run a small portable music player such as a Walkman.

This power source from Sony could be an eco-friendly solution to battery disposal problems and a cheap source of battery power. (They probably taste much better than conventional batteries, too.)
