Scientists Develop "Paint" To Help Cool the Planet

Posted by samzenpus on Thursday November 27, 2014 @12:59PM from the it's-getting-hot-in-here dept.

AaronW writes Engineers at Stanford University have developed an ultrathin, multilayered, nanophotonic material that not only reflects heat away from buildings but also directs internal heat away using a system called "photonic radiative cooling." The coating is capable of reflecting away 97% of incoming sunlight and when combined with the photonic radiative cooling system it becomes cooler than the surrounding air by around 9F (5C). The material is designed to radiate heat into space at a precise frequency that allows it to pass through the atmosphere without warming it.

What about for cars? by Anonymous Coward · 2014-11-27 13:06 · Score: 2, Interesting

Cars being greenhouse ovens is a terrible issue. Not just because it's uncomfortable getting into the car on a hot day, but because people accidentally kill pets and children by leaving them in a hot car every year (and others not so accidentally). Surely there's better tech than what we use today to prevent our automobiles from becoming lethal ovens.
