This is so crazy, that i never thought it could work.

In order to turn pennies into batteries, another electrode and an electrolyte are needed. In this case, dimes (zinc) are used as the positive electrodes and salt water is used an electrolyte. Copper wire, galvanized nails, and lemon juice are also popular and cheaper solutions. Such a battery produces a differential of about 0.5 volts.

It works on the same sort of idea as getting electricity from a lemon. The electricity is coming from the salt water (or lemon juice, depending on what you’re using) and the penny acts only as an electrode. Think of it like a wire connecting up two batteries. Never the less it is still cool to see a project like this, I didn’t think that it could produce enough current, I guess I was wrong. There are lots of pictures in the article.
