Hook up a spud to a couple of cheap metal plates, wires and LED bulbs, they argue, and it could provide lighting to remote towns and villages around the world.
all you need is two metals oe an anode, which is the negative electrode, such as zinc,
and a cathode, the positively charged electrode, such as copper. The acid inside the potato forms a chemical reaction with the zinc and copper,
and when the electrons flow from one material to another, energy is released. This was discovered by Luigi Galvani in 1780
But you can put many materials between these two electrodes to get the same effect.
and copper electrodes generates portable energy at an estimated $9 per kilowatt hour, which is 50-fold cheaper than a typical 1. 5 volt AA alkaline cell or D cell battery,
A zinc electrode that lasts about five months would cost about the same as a litre of kerosene,
You could also use other electrodes, like magnesium or iron. But potato advocates must surmount another problem before their idea catches on:
