This battery is environmentally friendly because it can run on rain water.It still needs the metals. Distilled water will NOT work, it has to be conductive. Whenever it runs out of power you just have to drain the water and refill it. If more power is needed, you can add a little bit of Clorox Bleach. It also works with other electrolytes, like lemon juice, vinegar, saltwater, or baking soda.
This is my first instructable so i am welcome to any criticism or suggestions.
Disclaimer: Alot of the methods of cutting, drilling, hammering, pummeling, incinerating, and sawing that I describe are dangerous and I strongly suggest you should go about all of the cutting, drilling, hammering, pummeling, incinerating, and sawing in your own manner that is safer than mine. I take no responsibilty for the actions you take concerning this instructable. Have fun! =).
By the way, this battery will only produce about 1 volt but will get a lot of current. For more voltage, hook together alot in a circuit.
PS: Just so you know, I'm only 12.
