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.

Windshield screens are the low-tech but far more effective method of keeping a car's interior cooler, typically by at least 20F when it's really hot out. Slightly inconvenient but unlike this paint, a windshield screen will actually make a difference.

Also great for city climate since heated up cars are acting like a heat battery making it significantly slower for a city to cool down once the sun goes away

Ideally there would be no openly parked cars but I guess this is the next best thing

Got in my car after work yesterday and it was 102F inside. It was awful

Lucky! I've seen 150 here in Louisiana.

And even higher when I lived in the Mojave desert. Like, if you didn't leave a window cracked there's a real chance your windshield cracks.

Must have had you wishing for a nuclear winter.
