Engineers Develop “White Cooling Paint” That Could Reduce Use of Air Conditioning

The idea that a simple paint could could compete with modern air-conditioning sounds crazy, but researchers at Purdue University say it could become a reality thanks to a cool new “radiative cooling paint” they developed.

Engineers at Purdue University recently unveiled a revolutionary white paint that they claim can keep surfaces up to 18 degrees Fahrenheit (7.8 degrees Celsius) cooler than their ambient temperature, by absorbing almost no solar energy and actually sending heat away from the surface it is covering. Think of it as a way of turning basically any space into a refrigerator, only without the energy cost.
