New super-thin film acts like "air conditioner" for buildings

Engineers at the University of Colorado Boulder have developed a thin, artificially structured "metamaterial" that can cool objects without the use of water or energy. The film works to lower the temperature of the surface beneath it through a process known as "passive cooling," meaning that it vents the object's heat through thermal radiation while bouncing off any incoming solar energy that may negate those losses. As described last week in the journal Science, the glass-polymer hybrid material...
