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
...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.
Nissan also detects you having sex in the car and phones the info home.
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.
Is it white paint?
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.
What kind of garbage article doesn’t include the units!?
What for? Almost no country uses Fahrenheit.
If that's how scientists did science, we'd have mountains of confusion. "Eh, most people will get it. Good enough."
Information like this is global. It's a single "C" for clarity. That's not an unreasonable ask.
You’re right. Everything should be in degrees kelvin by default. Problem solved.
They're currently working hard for a way to make it subscription.
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.
trick is to paint the windows
Also this is problematic:
12 degrees cooler
But by what scale? If it's Flaffenfeit, it's just half an ounce!!!
To add to your comment, ceramic window tint is a night and day difference. My steering wheel, shifter, and all couldn't be touched after work. I wore driving gloves to get home. With the tint there slightly warm and the AC doesn't take half the drive to catch up, the car is cool by the first stop light.
Maybe they should sell cars with that by default instead?
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
Ah yes. Why reduce the temperature of your car by 12 degrees when you can just alter the entire planet instead.
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.
Might be the most interesting thing Nissan has developed in two decades.
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
wouldn't this also work on buildings? pavement?
No, only Nissans. It says right there.
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)
Why did you post a picture of an empty street?
I don't understand, why did you post a random picture of some pavement ?
As someone living in Wisconsin with salty road winters, I'll say that Nissan's reputation is mostly trash here based specifically on their paint

Anything to not add a cooling system to the ev batteries.
This is a most excellent place for technology news and articles.
