Forget Eskom, buy spuds
TEL AVIV: An electric battery based on boiled potatoes could provide a cheap source of electricity in the developing world.
The treated potato battery generates energy that is five to 50 times cheaper than commercially available batteries, Yissum Research Development Company in Jerusalem said.
A light powered by the battery is at least six times more economical than paraffin lamps often used in the developing world.
Researchers discovered a new way to construct an efficient battery using zinc and copper electrodes and a slice of an ordinary potato.
They found that boiling the potato before use in electrolysis increased electric power up to 10-fold over the untreated potato and enabled the battery to work for days and even weeks. – Reuters
