Researchers develop building material that cools by reflecting heat into space
Stanford, Calif. (UPI) Dec 1, 2014 - Researchers at Stanford say they've developed a material that cools itself by beaming excess heat into space; they hope it can one day be used to keep buildings cool on hot, sunny days. Traditional ideas about thermodynamics suggest an object like a building can't be cooled below the temperature of the surrounding ambient air without the assistance of a something like air conditioning. ... more
