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.

There’s no paint on the planet that will make most of their cars cool.
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.
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 was working outside in 96F and nearly 50% humidity within the past week.
If we continue trying to work outside during the middle of the summer day, as our summers get hotter every year, people are going to start to die.
I wonder how many it will take for America to adjust. I assume a lot more than I’m comfortable with.
I was outside in 96F yesterday herding my ducks for 10 mins and my whole night was ruined because I got so sick from the heat.
Idk how people who work outside constantly do it
Must have had you wishing for a nuclear winter.
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.
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.
Yeah, EVs are the worst kind of the privacy-invasive cars I agree
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?
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.
Which cameras?
I don’t think they have interior cameras (although other manufacturers do), but the front and backup camera feeds provide plenty of information as well.
Then there’s also this, if you need any more reason to be concerned.
I don’t think they have interior cameras
Can just stop there. Unless people are banging on the bonnet, not sure what the point is.
If you read the linked article you will find that exterior cameras feeds are plenty invasive enough.
I don’t disagree, but this is what was said:
Nissan also detects you having sex in the car
Unless there are cameras in the car then no.
While this fucked up, documenting sexual orientation is not exactly recording sex. Someone could simply use GPS and see that the only place in the area that’s open is the gay bar and infer from that, or even lip reading.

You know, we can use vision ai services to do that now, dang yo time flies
so you’re suggesting that it’s feasible to use a video stream from the car to read lips by, what, paying out of pocket to send the video stream over the built-in cellular? Possible, sure. Then receiving it at a datacentre and running one of the most computationally intensive algorithms in existence on the video stream, 24/7? Or at least only when I’m using the car? so the datacentre is processing presumably tens or hundreds of thousands of these all at once, so at let’s say 5mbps per video that could easily be multiple terrabits per second of bandwidth, consuming megawatts of power in order to spy on people in probably the least efficient and most expensive way imaginable, and all to determine that I said I like coke rather than pepsi so the car company can receive $0.01 in selling that to some ad company?
Is that scenario possible? Yes. Is it happening? I am certain that it’s not in any rational company. The same line of reasoning applies to listening to your phone’s microphone or camera, except there you’d also notice your phone getting hot and the battery dying in an hour or two.
The GPS thing is feasible. I don’t know if they’re doing that but they could. As soon as you mention transmitting video feeds or cloud AI you’re in conspiracy territory.
||Now, Tesla’s on-device AI processing using the driver’s power bill to analyse video on-site and only send the tiny results into the cloud… is very different. ||
no.
My wife’s going to be pissed when she gets that call…
Is this revolutionary invention called white paint?
Veeerry reflective white paint. Probably not street legal
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? 😮
At the… Ugh idk. They all have super thin paint nowadays. Especially the more expensive brands.

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.
Okay that’s racistLol. Wouldn’t want to see that applied to people although I can imagine the rhetoric.
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!

Everyone wants to be Mr Black.

They’re currently working hard for a way to make it subscription.
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
Ok, so don’t paint it on any concave surfaces. Most buildings have flat or convex surfaces.
It can reflect it out to space. It is possible to make paint the keeps things below ambient. Obviously you’re correct, but only for things not facing upward. Upward facing things will bounce the energy back away from Earth.
Oh great so now the rest of the universe has to deal with it. Really just kicking the can aren’t we
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?
No, only Nissans. It says right there.
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.
great video. Its wild that it is functioning as an IR emitter and just beaming things into space.
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.
Where is this?
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.
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
Considering it’s no an American brand I’d say Celsius
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.
I was hoping I’d see nighthawkinlight in the wild here.
Only reason I’m here lol
Neat. Now paint the inside.
so it radiates heat into the vehicle?
How else are you going to entice passengers to take off all their clothes?
so, what temperature is inside the car? scientist have found out its actually the glaspanes that makes cars hot, just saying.
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
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
So… You want to turn off the sun? This has nothing to do with climate change, the sun hasn’t changed intensity in a few 100 years, so sun makes things warm
Lol
You’re right, running AC more off of internal combustion engines is a better path to the solution.
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?
Blow up the sun. Easy.
I like blowing things up.
Lol
Can they develop a paint that reduces the amount of cars? That would be more helpful.
This might match your criteria:
(Jokes aside, I do agree with your sentiment)
I don’t understand, why did you post a random picture of some pavement ?
Why did you post a picture of an empty street?
🙄
12 degrees? I guess that’s cool but still well within egg frying temperature around here.
