 Scientists reported the development of a "smart" roof coating, made from waste cooking oil from fast food restaurants, that can "read" a thermometer. The coating automatically switches roles, reflecting or transmitting solar heat, when the outdoor temperature crosses a preset point that can be turned to the local climate. Roofs coated with the material would reflect scorching summer sunlight and reduce air-conditioning bills. When chilly weather sets in, the coating would change roles and transmit heat to help warm the interior. According to Ben Wen, leader of the research project and vice president of United Environment & Energy LLC, Horseheads, USA, the biobased intelligent roof coating could reduce both heating and cooling costs as it responds to the external environment. In producing the coating, waste cooking oil is processed into a liquid polymer that hardens into plastic after application.
