Sony Introduces Bio Battery

Japan's Sony Corp's lithium-ion battery has problems.

The alternative – a new bio battery.

The bio battery is a passive battery system that breaks down sugar to generate the world's highest level electric power of 50mW from a cell. 

The ecologially-friendly energy source, in the form of four cubic cells

, will generate enough electricity to drive a Walkman music player.

Now when kids listen to too much music parents will have another reason to tell them that too much sugar is not good for them.

I wonder how long the sugar cubes will last.
