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?
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
Thicker paint so more chipping resistance? Where do I sign up? 😮

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.
In some countries, you get a penalty on insurance depending on the car color, with maximum penalty reserved for black cars.
How is it with silver and grey? Do you get a heavy penalty for them too? If it rains, snow and/or are foggy can it be very tricky to see silver and grey cars.
I’m not really sure. I think white and red are the cheapest.
Growing up I remember hearing that red cars were the most expensive for insurance, as owners of red cars had the highest incidence of speeding and dangerous driving.
Heavy rain or snow all that matters is if the lights work!

Twelve degrees what? A degree Celsius is more than twice a degree in Fahrenheit.
State your units, FFS.
I will assume celsius since the IR image shows around 45 and 35 degrees in direct sunlight.
The scientific consensus is that unless otherwise stated it’s Celsius.
In scientific papers you just write 14° you don’t need to specify the unit.
So I’m just going to use that rule and assume Celsius.
1kg is more than twice 1lb (2.2lbs) but 1C is only 1.8F
And 1m is only 12 crayons.
Nissan also detects you having sex in the car and phones the info home.
I’m curious where that’s from? News, or you made up from privacy policy?
Mozilla’s analysis if the policies, see my other comment in the thread.
Okay, I found one.
But I guess it’s to clarify what kind of data could possibly be collected and not that they actively collect and use them. I guess Ford can do that too, although they don’t specify in their privacy policy.
They’re not interested in your sexual orientation.
But, like, why is that listed then? Why would Kia and Nissan say they collect information on your “sex life” and “sexual activity” respectively of they’re not? What’s to gain from keeping the window open if you’re using it?
Nissan invents white paint
Nasa have developed a paint for spacecraft that can be any color including black and still have the properties of white paint. It’s only colored in the visible part of the spectrum but allows IR to pass right through.
Although you do need to paint the vehicle white initially as an undercoat.
If it’s like this stuff then it’s more than just white paint.
They’re currently working hard for a way to make it subscription.
I just love how humans will do anything other than actually focus on fixing the problem. Love it.
I would argue that the new paint could help alleviate the issue, since it would incentivise people to decrease use of the AC. My concern then would be how polluting is the production of the new paint compared to the current version.
My immediate thought was to wonder if this would help give kids who get left in a car by mistake have more of a fighting chance
Like reducing the number of cars.
Ohh too much traffic! 🤔 Let’s expand the freeways until you need a freeway to cross other freeways.
Just one more lane will fix traffic bro
Anything to not add a cooling system to the ev batteries.
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?
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.
It’s not so much the thermometer temp here in Louisiana. It’s the 80-99% humidity. At these levels your body’s main heat defense: Sweat - no longer works as it can’t evaporate fast enough or at all. Then it becomes an insulator and a feedback loop of hell. Like being wrapped up in a wet electric blanket.
I live in Pa, so our weather isn’t crazy hot like the south. I can’t imagine the weather where you’ve lived. 85F is my upper limit. Anything over makes me feel like I’m going to die.
I can remember a few summers in the desert where it would reach 130’s. And as a kid back in the early 90’s, we had the hole in the ozone too. No joke we had ozone warnings, and no outside recess cuz of it.
Plenty of summer nights were the temp never dropped below ~100f
Strangely, we often got winter temps below freezing.
Forget Nissan but I’ll take the paint.
Yeah but 350Z tho
I mean, if you’re a middle age bro with a retail supervisor job compensating to show off to teen girls, I guess.
I see, thanks for pointing out that I’m a stereotype. FML
TBF, the 350Z was the sports car to have when I was a teenager. Not my fault that I can only afford one just now in my mid-30s, haha. I blame Ronald Regan for screwing over working-class citizens. If I had the money my parents had, I’d be driving an EV by now.
(edit: and FWIW I’m in a happy relationship with an adult woman similar to my age)
And that’s 12 degrees Celsius (21.6 degrees Fahrenheit)! What kind of garbage article doesn’t include the units!?
Or 53.6 degrees Fahrenheit if you believe whoever wrote the page for Nissan lmao. I guess they just typed it into a converter with no context, and the converter spat out an answer amounting to “if your thermometer says it’s 12 degrees C, that would be 53.6 degrees F”… but without that context.
