Energy-Free AC? Heat-Reflecting Wrap Could Cool Without Power

A heat-reflecting, futuristic supermaterial that looks like a roll of plastic wrap could one day cool both houses and power plants without using any energy, according to a new study.

Unlike solar panels, the material keeps working even when the sun sets, with no additional electricity. And the plastic wrap is made up of cheap, simple-to-produce materials that could be easily mass-produced on rolls.

"We feel that this low-cost manufacturing process will be transformative for real-world applications," Xiaobo Yin, a mechanical engineer and materials scientist at the University of Colorado Boulder, said in a statement.
