Nissan develops paint that keeps cars cool in summer heat (www.asahi.com)

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.

I seriously doubt that, tests have been performed comparing black and white painted cars, and the difference was insignificant. The heat buildup in a car is due to the the sunlight entering through the windows.

trick is to paint the windows

Also this is problematic:

12 degrees cooler

But by what scale? If it's Flaffenfeit, it's just half an ounce!!!

And an ounce is nowhere close to a decimeter!

I bet Kelvin couldn't agree more. But to be fair, he started a bit on the negative side. And called everything above that plus.

A bushel of paint should be enough to cover 12 roods.

Dammit, I needed 5.5 qt paint to cover one parking spot

Our European friends are going to need you to convert that to kilometers.
