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 it white paint?
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.
Mythbusters did an experiment with a black car and a white car hitting in the sun. The black car was 12 degrees Celsius hotter. Claiming that the paint makes no difference is such a weird take. I thought this was common knowledge as well as many people I’ve met avoid darker colours in summer and such.
Summer was hard on me in my teenage goth years.
Can’t really get many light shades of black.
I think i’m in love.
Careful, I don’t think that mask is n95 or anything.
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
You mean the one in the comment that the comment you replied to mentioned and linked to?
