Potatoes can be used as a solid organic electric battery and utilized in countries where electrical infrastructure is not yet established. Boiling the potato increases electrical power by 10 times and using zinc and copper electrodes on a treated potato will produce power 50 fold cheaper than 1.5 Volt D cell batteries. This is an incredibly efficient way of creating green power at a low cost, which can be grown in your backyard. There is one downside, the zinc and copper rods will corrode away and need to be replaced. The power created from the potatoes can be used by low powered devices, such as LED lights, communication devices, and small radios.
