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
