Sony creates paper battery

Pulp friction

Sony boffins have built a battery out of paper.

The so-called "bio battery" uses enzymes to catalyse the breakdown of glucose stored within the cellulose that forms the paper's wood pulp fibres.

Sony bio battery

The battery has a structure that keeps reaction elements separate to encourage the flow of hydrogen ions and, to keep the reaction electrically balanced, electrons.

These electrons can be harnessed as electricity.

The hydrogen ions and the electrons recombine with atmospheric oxygen to form water, again in the presence of a catalyst.

Sony bio battery

The battery derives from work Sony has put into biological power tech for some years. It created its first glucose-driven power cell in 2007, but this is its first to derive the sugar from cellulose.

The upshot is a very thin battery which, Sony reckons, can drive annoying musical birthday cards and such. It also suggested musical drinks cartons, with the glucose coming directly from the juice. ®

Musical drinks

Presumably battery enzymes digest the carton and the soda inside, while playing a selection of songs by 'Pop Will Eat Itself'?

As it is Sony, presumably the paper will be made from specially prepared trees.

The ones with the rootkit.

And for this!!!

"The upshot is a very thin battery which, Sony reckons, can drive annoying musical birthday cards and such."

The inventors will spend all eternity in the 9th circle of Hell!

'....with the glucose coming directly from the juice.'

So you can tell if it's a diet drink or not by how loudly it tells you how fat you are, i love it!
