So in a recent post we talked about the number two energy, the loowatt, using your fecal matter to produce energy with the added benefit of it being shaped out of horse dung, which is every interior designers first choice.  The next item we have to show you is one you can power  standing up, if you are of a certain sex, and is relatively the same in its energy source.  Yep you guessed it, urine.   The fact that urine contains many ions, which are electrically charged atoms, means that other fluids like water blood, semen, Coca-Cola, beer, etc… can be processed for energy like shown in the diagram below:

Back in 2005, National Geographic was talking to these Berkley Scientists about the development of a battery that produces 1.5 volts of electricity by taking two pieces of paper, soaking them in copper chloride sandwiched between plastic and then putting a drop of urine in a slit of the plastic, and voilà, electricity.  An array of applications have been stated–like cell-phone batteries, mp3 players, computers and cars.  This could make an interesting first date when your cell-phone battery indicator is blinking and you decide to go to the bathroom.  But hey, at least if your car runs out of gas at least you can persuade the officer to let you off for peeing in public.  Any other ideas?  Perhaps a little uncivil, but this  new eco-technology definitely brings new etiquette to our social and public lives.

Leave it to the Japanese to come out with the first public application.

Go ahead and do a google search of Nopopo and click on the shopping tab and you can have a flashlight with batteries for $40 or just the batteries alone for $15.  Not a bad deal and a good gift to crack some jokes over and try out at a birthday party.
