Haaretz: Although making a simple battery from a potato is a common child’s science project, researchers at the Hebrew University of Jerusalem have found a way to make a potato battery more efficient: by boiling the potato first. Published in AIP’s Journal of Renewable and Sustainable Energy, their findings indicate that boiled potatoes generate up to 10 times more electric power than uncooked potatoes do. Because potatoes are grown in many countries around the world, in a wide range of climates, they could provide an economical and sustainable source of electrical power to developing countries.
