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.

No, it needs the zinc. Which has to be mined as ore and requires a lot of environmentally-unfriendly energy to refine into metal (if the mining weren't enough for ya...)

Yes (old comment to reply to, did you look at my stuff?)

When you put the more reactive metal in it, it replaces the Zinc in the electrolyte, so the electrolyte now contains the metal in the dissolved form and a layer of Zinc is formed.
So, the metal is actually getting consumed to give you back the Zinc.
In your earlier example, when you put the pennies in the vinegar, it forms copper acetate.
2CH3COOH + Cu -> Cu(CH3COO)2 + H2
Next when you put the iron in, since it is more reactive
Cu(CH3COO)2 + Fe -> Fe(CH3COO)2 + Cu
You see, the copper being formed here leads to that layer of copper, but the iron itself has now become Fe(CH3COO)2 which is basically not Iron.
To get back this Iron, you need to provide energy, and in doing so you will have to provide more energy than you actually produced.

I'm not sure what you're saying here?

this is how the world gets dumber everyday.
It's not environmentally friendly, it can't run solely on rain water. Perhaps you see the statement a fun joke? That being the case our senses of humour must differ, and there's not much fun for either of us to bicker about it.
