The researchers at the University of Colorado, Boulder and the University of Wyoming, Laramie, have developed a super-material that can function as an air conditioner without using any energy. The heat-reflecting, metamaterial, which resembles an ordinary aluminum foil, works on the principle of passive radiative cooling and can prove “transformative for real-world applications.”

The three-layered material is engineered in a way that the top surface deflects almost 100 percent of the incident light while the bottom layer passively radiates trapped heat, writes Live Science. The researchers said about 10 to 20 square meters of this material is sufficient to cool off a single-family house in summer.

The material is cheap and simple-to-produce, which makes it an ideal solution for use in large-scale commercial and residential applications, notes Forbes. The thermoelectric power plants, which rely on water and energy to cool off their machinery, might find it viable to switch to the new material.
