Potato battery

  1. May 22, 2004 #1
    hey guys whats up?

    just recently ive been working on this potato battery thingy in chemistry class and the highest i can get it is 15 volts. i knwo there are a lot of variables involved but are there any suggestions that you might think would help achieve a higher voltage? i was thinkin of soaking the potatoes in a salt saturated thing of water...(more sodium). any ideas would be greatly appreiciated.

    ps- nothing to insane.. we are using magnesium and copper as the 2 metal things.. ie no lithium... and preferably materials that could be bought at the local stores.

    well.. yeah ive done that already (sorry for not mentioning). we had about a 10 pnd bag, cut em up into 4ths and connected em all. the highest we got was 15... then after that it wouldnt go past 3...
