Still in prototype form, Japanese researchers at Sony have found a way to convert old, recyclable paper into usable electricity. At a recent exhibition, children were invited to test the “bio-battery” by dropping paper into a liquid concoction and shaking it to produce electricity.

How does it work?

Using various enzymes, the paper is “digested” down into smaller chemical components – first to the glucose sugar found in plant cells, next to its basic building blocks of atoms and then finally to electrons and hydrogen ions. The movement of these electrons through a wire produces the phenomenon we know of as electricity.

The technology is still far from being commercially available but can already produce enough power to operate a small fan or a basic music player.
