Sila Sutharat, a roasted chicken street vendor from Phetchaburi, Thailand, has come up with an ingenious way of cooking chicken. Instead of an oven or a charcoal barbecue, he uses 1,000 mobile mirrors that concentrate sunlight into a strong beam. He basically cooks meat with over 300 degrees Celsius of natural sunlight.
Like most other street vendors, Sila used to cook his chicken over a charcoal fire, but that all changed in 1997, when a mundane observation gave him a brilliant idea. One day, he was hit by the sunlight reflected off the window of a passing bus, and he felt its heat. “I could possibly change it into energy,” Sila told himself, and started working on a contraption to capture the sunlight and use it to cook his chicken.
