Researchers in Jerusalem for the Israeli company Yissum have developed super simple, sustainable, organic electric batteries which are powered by treated potatoes. The new potato battery research has recently been published in the Journal of Renewable and Sustainable Energy. The apparently highly efficient battery is made from zinc and copper electrodes and a slice of boiled potato. The act of boiling the potato increased the electric power around 10 fold in comparison to an untreated potato, giving it power for days, and sometimes weeks depending on the conditions. The potato batteries are also, of course, considerably cheaper than regular commercial battery cells. The technology has officially been made available free of charge to the developing world.
