THE BAKER WILL THANK YOU:Smart Windows That Let In Light But Keep Out Heat Are Almost Here (Co.exist, 8/22/13)
Posted by Orrin Judd at August 24, 2013 1:08 PMScientists at Lawrence Berkeley National Lab, in California, have developed a nanocrystal coating that gives more control over the light spectrum, and therefore how much near-infrared light (which produces heat) and visible light (the stuff you like) enter a room. The clever bit is that the window appears completely clear, even when little heat is entering."When used as a window coating, our new material can have a major impact on building energy efficiency," says Delia Milliron, who led the work (she talks more about it in the video below). The researchers write up their findings in a recent issue of the journal Nature.
