Batteries are used to run almost every electrical device we have, including our indispensable mobile devices. Imagine if batteries had never been invented, we would be solely dependent on wall sockets and wired technology. Batteries are not, however, that kind to the environment, and they have been known to suffer catastrophic failure occasionally.
Sony has come up with a battery that does not run on fancy metals, instead, it runs on what is basically termite feed: paper and cardboard.
The company has been refining the technology for years now, and how the battery works is simple. The battery itself consists on a thin sheet of material known as a “bio-battery”. Enzymes are used to break down sugar and turn it into ions and electrons, creating an electric current. These bio-batteries can run on pretty much all kinds of things, including soda and fruit juice. (I’m sure you’ve all heard of potato and lemon batteries)
The problem with that is, rather than use these things as a battery, we tend to eat them.
Sony has come up with their idea of using cardboard as a power source, by adding another enzyme into the mix, that is able to break down cellulose into sugar. All that is needed to work this battery is cardboard, soaked in water and the enzymes. There are two enzymes needed, the first is to break down the cellulose of the cardboard into sugar, and the second is used to produce the electricity.
Currently the battery is said to produce enough electricity to power an MP3 player, which is pretty impressive. I wonder if this kind of battery can be further improved upon. Maybe one day it will be used to replace the batteries we use today.
