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?
I just love how humans will do anything other than actually focus on fixing the problem. Love it.
Ah yes. Why reduce the temperature of your car by 12 degrees when you can just alter the entire planet instead.
Lol
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
Uhh, what? The problem of things getting hot in the sun?
Lol
Blow up the sun. Easy.
I like blowing things up.
Is this revolutionary invention called white paint?
Vantawhite
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.
…the paint is six times thicker than the usual coating on the car body surface… looking to commercialize the paint on ambulances and other specialized vehicles as the first step.
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.
Everyone wants to be Mr Black.
Nissan invents white paint
If it’s like this stuff then it’s more than just white paint.
If it’s like that stuff then they didn’t invent it.
Well, they would have invented the specific formulation they’re using. I’m sure it’s not exactly like this but I wouldn’t be surprised if it’s the same concept with microbeads.
No one invents anything totally new. It’s all adding on to what others have made in the past. Nothing has ever been created from scratch.
Nissan also detects you having sex in the car and phones the info home.
What ahaha.
Their privacy policy includes a provision that they can use the cameras and GPS to infer things such as sexual orientation, so yeah.
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?
So fucking glad I got my car before they added all this shit.
It’s going to prevent me from getting any EVs that come out that I can afford too. I’m not signing a fucking privacy policy for a car.
Might be the most interesting thing Nissan has developed in two decades.
They found a very interesting way of selling their hybrid cars as full on EVs where I live. Their e-power stuff are small ICEs working as generators for electric motors that then drive the wheels. Apparently the fact that the wheels get all their power from an electric motor makes it definitely not a hybrid no sir, despite the fact the cars have tiny ass batteries and the single source of power for the whole system is the ICE. Also they somehow have worse fuel efficiency than many contemporary ICEs that cost quite a bit less. I don’t understand Nissan.
A few car companies seem to be doing that. Toyota(?) here are advertising their hybrid vehicles as “self-charging electric vehicles” instead of a hybrid, even though there’s no way to plug them in and not have them self charge.
Forget Nissan but I’ll take the paint.
12 degree °C or °F???
°C, which is not bad. Official press release (I think): https://global.nissannews.com/en/releases/nissan-trialing-cool-paint-technology
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.
up to 12 degrees cooler
okay but why? What tangible difference is that going to make?
Also is this on the interior or exterior?
12 degrees on roof, 5 on car seat. It’s in the article
Never heard of Asahi.com and not about to click on it. But thanks for getting that information.
Asahi is perfectly legitimate and one of Japan’s largest news organizations.
Just because you haven’t heard of something doesn’t mean there’s anything wrong with it.
I didn’t say it wasn’t.
You said you’re “not about to click on it”, which is implying that you think it is not a good news source.
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.
1kg is more than twice 1lb (2.2lbs) but 1C is only 1.8F
And 1m is only 12 crayons.
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.
Anything to not add a cooling system to the ev batteries.
wouldn’t this also work on buildings? pavement?
Is metal paint and concrete paint the same thing? I’m not a painter
Ultimately, they can be, but there’s lots of differences between them once they reach the bucket you buy. They have different adhesion qualities, but that could be addressed with an appropriate primer. They have different final finish surface requirements, which could be an issue for how the paint works. I remember seeing dragonfly-wing-style paint that was white when viewed perfectly straight buy blue when viewed at any off angle due to a microscopic vertical grid of blue walls. There may also be a required clearcoat component that may not be compatible between the two surfaces. Metal paint is also designed to handle the flex of metal where as concrete paint would barely be concerned about that but possible address crumbling instead.
Edit: and after reading the article, it’s a radiative-cooling paint rather than a reflecting coating. Concrete has a much lower thermal conductivity so this may not be effective in transferring heat out of the concrete.
Metal paint is concrete paint. Microsoft paint is abstract paint. This comment is metaphorical paint.
No, only Nissans. It says right there.
12 degrees? I guess that’s cool but still well within egg frying temperature around here.
