High Tech Mirror Beams Heat Into Space (IMAGE) Stanford University School of Engineering Caption In this illustration a panel coated with a multilayered material designed by Stanford engineers is shown to help cool buildings without air conditioning. The material works in two ways. It reflects incoming sunlight (the sun's reflection seen on the panel) that would otherwise heat the panel. And it sends heat from inside the structure directly into space as infrared radiation (reddish rays). The blue areas on an otherwise warm roof show the cooling effect. Credit Nicolle R.
