Move over air conditioning, there’s a cool new kid on the block: “radiative cooling paint.” Researchers at Purdue University have crafted a paint that can make surfaces up to 18 degrees Fahrenheit cooler than the air. Think of it as a personal refrigerator, no electricity needed.
This paint is no ordinary coating; it defies the sun’s scorching rays by absorbing minimal solar energy and sending heat away from surfaces. Traditional white paint pales in comparison, reflecting just 80%-90% of sunlight. In contrast, this wonder paint reflects 95.5% of sunlight and radiates heat efficiently.
The quest for cooling paint dates back to the ’70s, but Purdue’s engineers spent six years perfecting a formula based on earth-abundant calcium carbonate.
This paint is a game-changer for energy-efficient cooling. It shifts the balance by reflecting sunlight, reducing the need for air conditioning, and even helping combat global warming by sending excess heat into space.
