Scientists Develop "Paint" To Help Cool the Planet

Posted by samzenpus on 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.

    Surely there's better tech than what we use today to prevent our automobiles from becoming lethal ovens.

    Certainly there is. You can just cook your kids and pets at home, no need to waste the gas going out at all. Home ovens have been large enough to do this for decades now. People are so wasteful!
