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.

wouldn't this also work on buildings? pavement?

Probably yes, but it may not actually be doable. Not just because of how much there is to paint, but because the energy doesn't just evaporate. It's got to go somewhere. In this case I'm assuming it's reflected, even if diffused. If everything does this, things that don't (people, cars, pets, etc) will get all that extra energy.

Wouldn't want to end up in a situation like this: https://www.businessinsider.com/death-ray-skyscraper-is-wreaking-havoc-on-london-for-a-few-totally-insane-reasons-2015-7

The amount of folks who have melted their shitty low quality thermoplastic patio furniture with their sliding glass windows will always amuse me, but overall I don't consider IR radiation to be a big problem. Using a bunch of VOCs to paint everything and pollute a city would be though.

You ever seen that curved building that focused the sunlight into a spot in front of it and melted cars? Lol
