Nissan Motor Co. said it has developed a new type of paint that significantly reduces the temperature inside vehicles parked in direct sunlight.

The surface of a car coated with the innovative material remains up to 12 degrees cooler than that of a vehicle with standard paint, tests showed.

The company said the coating material can help rein in the temperature rise not only on the car’s body but also in the vehicle when exposed to direct sunlight.

    Is this revolutionary invention called white paint?

      This is because the substance artificially reproduces a process known as radiative cooling on the painted surface. A typical example of radiative cooling is a phenomenon where the ground releases heat to cool off.

      Nissan worked with the Chinese enterprise Radi-Cool as it specializes in the creation of radiative cooling technologies and materials.

      However, one obstacle remains: the paint is six times thicker than the usual coating on the car body surface. The substance is also more expensive, which would add to the total cost of a new vehicle.

      That, in turn, makes it difficult for the coating material to be utilized for mass-produced passenger automobiles.

      For this reason, Nissan is looking to commercialize the paint on ambulances and other specialized vehicles as the first step.

        With 6 times thicker paint there’s a chance it also wouldn’t rust like a proper Nissan and we can’t have that, now can we

        This is the best part of the article.

        After driving ambulance during Australian summers, in the Great Victorian Desert, this would assist so much with operating temperatures. A literal life-saver, if the AC ever broke, also.

      It’s staggering to me the number of black cars being sold in hot countries like Australia. Not to mention just how hard they are to see against the background of a bitumen road.
