Potato batteries may provide cheap power

TEL AVIV, (Reuters Life!) – An electric battery  based on boiled potatoes could provide a cheap source of  electricity in the developing world, according to the technology  transfer company of the Hebrew University of Jerusalem.

The treated potato battery generates energy that is five to  50 times cheaper than commercially available batteries, Yissum  Research Development Co said on Thursday. A light powered by the  battery is at least six times more economical than kerosene  lamps often used in the developing world.

“The ability to provide electrical power with such simple  and natural means could benefit millions of people in the  developing word, literally bringing light and telecommunication  to their life in areas currently lacking electrical  infrastructure,” Yaacov Michlin, chief executive of Yissum, said  in a statement. The findings were published in the June issue of the Journal  of Renewable and Sustainable Energy.

Haim Rabinowitch and research student Alex Golberg at  Israel’s Hebrew University jointly with Boris Rubinsky at the  University of California at Berkeley discovered a new way to  construct an efficient battery using zinc and copper electrodes  and a slice of an ordinary potato.
