Pee Powered Battery
To make the battery, Lee and his colleagues soaked a piece of paper in a solution of copper chloride and sandwiched it between strips of magnesium and copper. This sandwich was then laminated between two sheets of transparent plastic.
When a drop of urine is added to the paper through a slit in the plastic, a chemical reaction takes place that produces electricity.

The prototype battery produced about 1.5 volts, the same as a standard AA battery, and runs for about 90 minutes. Researchers said the power, voltage, and lifetime of the battery can be improved by adjusting the geometry and materials used.
Urine contains many ions (electrically charged atoms), which allows the electricity-producing chemical reaction to take place in the urine battery. Other bodily fluids, such as tears, blood, and semen, would work easily as well to activate the battery.

I am confused. You have the elecrolyte (copper chloride), the dissimilar metals (magnesium and copper).
1) Does the urine really contribute anything but the solvent (water)?!
2) If this is really ‘urine powered’, does adding additional urine provide additional output? How many times can you add a drop of urine and get that ‘90 minutes’ of output? And how much copper chloride is left in the paper when you are done? How does the copper chloride participate in battery operation?
3) Doesn’t the output look about the same if you use distilled water?
4) If this is about the ions in urine, why doesn’t urine work with a plain paper dielectric layer?

I really have to wonder what made anyone think to use urine in this manner.
Did the thought of how to use urine for something useful came first, or was “what can I power a battery with” first?
Does what a person consumes alter the output of whatever it is that is needed in the urine to make this work?
Can person eat/drink specific things to make a better battery?
Are there foods/drinks that should be avoided if you are going to use your urine to power a battery?

Thanks!
It worked. I am now pissing on my AA batteries to charge them.
Works even when they are completely empty.
My girl called me when she got stuck in traffic.I advised her to pee on her car battery under the hood.She was home in 10 minutes.
Piss rules!
Thanks again.

I once saw a guy pee in the tank of a car.
Now I understand……
It was an electric car!

Exxon has many secrets! This is no longe one of them! Pee also aids in the relase of H2,O2, a very powerful fuel! MIT has a catalyst that gets H2,O2 fuel directly from solar type cells for night-time use in super-insulated off gridd dwellingsm none the less! OR: even your battery bike or car! Soon, thechnologies will relase humanity from the capitalists slavery cycle, and give us enough know-how to have basic off gridd survival for little but intelligent efforts – then we can concentrate on Arts, Music, and Sex, as G d intended for mankind! The "Rat-Race" is near its end, Haliulia!

It seems we should always bring a bottle of urine
