It sound like something out of a Sci-Fi movie.
Researchers at Stanford University have developed a nanophotonic material that not only reflects sunlight and prevents heat from being absorbed, but it actually beams the thermal energy at a specific wavelength so that it leaves the earth's atmosphere.
A recent post on the Green Prophet blog details the discovery, which, if developed and implemented on a mass scale, would go along way toward improving the energy efficiency of buildings.
For instance, the Stanford research team, led by Shanhui Fan, professor of electrical engineering, said that by covering just 10% of a roof with the nanophotonic material would mitigate about a third of the building's cooling load, according Green Prophet.
