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.)

Implications - Society's dependency on electricity and mass adoption of consumer gadgets creates a window of opportunity for engineers to create batteries and charging solutions that are sustainable and easy on the environment. By using innovative methods to generate energy, product designers can reach environmentalists and tech lovers who want to reduce their impact on the Earth.
