Sharjah 24- AFP: Scientists have invented a new kind of thin material that can cool a surface against the heat of the sun without using energy or typical air conditioning, a study said Thursday.

The glass-polymer hybrid material measures just 50 micrometers thick -- slightly more than aluminum foil -- and can be manufactured cheaply, researchers said in the journal Science.

"We feel that this low-cost manufacturing process will be transformative for real-world applications of this radiative cooling technology," said researcher Xiaobo Yin, an assistant professor at the University of Colorado, Boulder.

Uses for the product could include keeping buildings and other objects cool, as well as extending the life of solar panels.

"Just 10 to 20 square meters (yards) of this material on the rooftop could nicely cool down a single-family house in summer," said co-author Gang Tan, an associate professor in the University of Wyoming's Department of Civil and Architectural Engineering.

While not on the market yet, researchers said the material is lightweight, easy to fit to curved surfaces, and fairly simple to mass produce.
