July 2009: According to the Bangkok Post newspaper, Sila Sutharat has operated a solar-powered chicken roasting stall in the Muang district of Phetchaburi since 1992. He splits and hangs chickens 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. Sila 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.) Though the reflector array cost 30,000 baht to build, he has no fuel expenses and is able to sell the chickens for 160 baht each. Sila has even received an honorary bachelor’s degree in “production technology” from Phetchaburi Rajabhat University for his inventiveness.
