Boiled potatoes are known for being a part of a healthy meal. Now, a gaggle of Israeli researchers consider they make good batteries as well. Batteries create electricity via a chemical response between 2 different electrodes and one electrolyte.

A team from the Hebrew College of Jerusalem say their replace on the standard potato battery could be an vital vitality supply throughout the third world.

Since the 19th century, it has been identified that inserting zinc and copper electrodes into a potato sees the vegetable act as an electrolyte and produce a present. A easy twist on the method has outstanding results.

By boiling the analysis group lowered the inner resistance of the potato battery and that approach they had been capable of generate 10 instances extra vitality than the common potato battery. Boiling the potatoes first increases the output to nearly half that of a industrial double A battery. Works for days and even weeks.


Grown in more than hundred countries, potatoes are cheap and with a long shelf-life can be stored without putting them in the refrigerator. According to the research team, all these qualities of the potatoes make them an ideal energy source. These findings can benefit millions of people.

After discovering this, researchers believe it will become distributed in many countries, for many people and provide them with essentials that people in the developed world take for granted.

Researchers add up that the boiled potato battery produces electricity between five and fifty times cheaper that its commercial equivalent. This is at least six times more economical than kerosene lamps used the world over.

However, remember that potato is not the energy source, but it connects the two metals and helps electrons flow to produce electricity.
