Waste paper powers futuristic Sony battery

London, Dec 20 (IANS) Sony which offered an iconic product like the Walkman, running on a bio battery, has now come up with one that digests waste paper to provide energy.

The prototype on display at Eco-Products 2011 in Tokyo, uses enzymes to break down waste paper into a fuel which can be used to power a tiny fan.

The process is unlike conventional batteries and much more like the action of a digestive system, the Daily Mail reported.

A digestive enzyme, cellulase breaks down the cellulose in paper into glucose, a sugar that Sony’s bio batteries can use as fuel.

The company’s bio batteries are now so advanced that the company showed one battery thin enough to fit inside a greetings card alongside the paper-digesting battery.

It uses fruit juice for fuel, and can generate enough power to play a melody from inside the car. As it stands, the paper-eating battery can generate a very small amount of power.
