Solar-Barbecued Pork From A Glass. Stock Photo

A man has operated a solar-powered chicken roasting stall in the Muang district of Phetchaburi since 1992. He splits and hangs chickens or pork vertically against a grill that faces hundreds of small concave mirrors reflecting sunlight at the grill and creating heat so intense that the chickens start to smoke in just a few seconds. He says he can roast up to 50 1.6-kilogram chickens between the hours of 7 a.m. and 11 a.m., taking just 10-15 minutes each in good sun. The stall is not open during rain. He has no fuel expenses.
