Electric power from potatoes

Monday, February 28, 2011

Slices of freshly cooked potatoes can provide electricity for remote, off-grid communities, says a research team at the University of Jerusalem. A slice of potato can generate light for 20 hours, and several slices could power simple medical equipment, or even a low-powered computer.

The work was described last year in the Journal of Renewable and Sustainable Energy and hinges on a recent discovery that electricity flows from membranes disrupted by boiling. Potato batteries are estimated to generate electricity at a cost of about US$9 per kilowatt hour, about the same cost as AA alkaline batteries. D cells generate electricity for about $50/kWh.

Expect to see another debate about "food or energy" to develop. The "antis" argue that these "food batteries" would be grown and used in areas of Africa where food may already be in short supply. Proponents, on the other hand, say many potatoes can't be moved to city markets in time to prevent them from rotting. BF
