The Power of Pee

Written by Hank Green on 14/04/06
{mosimage} It's cheap, non-toxic, and we've got plenty of it. Why not find a way to use it. Some crazy scientists at Singapore's Institute of Bioengineering and Nanotech have managed to harness the power of urine to create a substantial amount of electricity.

The 'battery' is created from a piece of paper soaked in a copper chloride solution sandwiched between strips of magnesium and copper and then laminated between transparent plastic films.

When a few drops of urine are added to battery, the urine reacts with the copper chloride producing as much energy as a AA battery.

Imagine the day, not to far in the future, when our iPod runs out of of juice and all we have to do is squeeze out a few drops to rev it back up.

OK, so this is mostly useful in medicine, where the electricity is actually being used to text the urine being used to create the electricity. Maybe a little less universally applicable, but still extremely cool.

An ultra portable power source like this could also be included in survival gear. The batteries never go bad...as long as youy have to go.
