iPod running low on juice? Spud power to the rescue!

Why carry around an extra battery when you can use, nails, copper wire, alligator clips and two potatoes to power your ‘Pod? How can that be easier then carrying something like this?

    Alright. How does it work?

    Hurm, I think this is a hoax. To draw current, there must be a closed circuit. In other words, both the potato must be connected to create a closed circuit. But the potato in the video is seperate, so this isn’t logical.

    Nope, this isn’t a joke, this IS real, you can make a simple battery by placing a zinc strip and a copper strip in an acid. At the zinc strip, the acid dissolves the zinc freeing electrons. At the copper strip, the acid uses those electrons to form hydrogen gas. Because the zinc strip frees electrons and the copper strip uses electrons, if you put a wire (in this case the MP3 player) between the two strips, then electrons will flow from the zinc to the copper. This is electrical energy.

    Google potato battery for more information

    Its basically the electrons are flowing from one potatoe to the other, so one potatoe becomes positively charged and the other negatively, however i think you only get bout 1.1 volts from this not 1.5v
