New metamaterial enhances natural cooling without power input

Cool wrappings: roll-to-roll glass-polymer metamaterial cools 24/7
A new metamaterial film provides cooling without needing a power input. Made out of glass microspheres, polymer and silver, the material uses passive radiative cooling to dissipate heat from the object it covers. It emits the...
