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 this revolutionary invention called white paint?

[–] [email protected] 23 points 2 months ago (9 children)

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 invents white paint

[–] Cethin 17 points 2 months ago (3 children)

If it's like this stuff then it's more than just white paint.

[–] [email protected] 11 points 2 months ago (1 children)

If it's like that stuff then they didn't invent it.

[–] Cethin 14 points 2 months ago

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?

[–] [email protected] 39 points 2 months ago (22 children)

And that’s 12 degrees Celsius (21.6 degrees Fahrenheit)! What kind of garbage article doesn’t include the units!?

[–] [email protected] 20 points 2 months ago (4 children)

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 for? Almost no country uses Fahrenheit.

[–] [email protected] 33 points 2 months ago (12 children)

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.

[–] [email protected] 36 points 2 months ago (1 children)

trick is to paint the windows

[–] [email protected] 14 points 2 months ago* (last edited 2 months ago) (5 children)

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?

[–] [email protected] 9 points 2 months ago (1 children)

Is ceramic tint different from ordinary tint?

[–] [email protected] 11 points 2 months ago* (last edited 2 months ago)

Yes. It contains ceramic nano particles that reflect UV without interfering with visibility.

edit: I meant IR. But it reflects both.

I just love how humans will do anything other than actually focus on fixing the problem. Love it.

[–] [email protected] 27 points 2 months ago (1 children)

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.

[–] [email protected] 17 points 2 months ago

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

[–] [email protected] 10 points 2 months ago (1 children)

Ah yes. Why reduce the temperature of your car by 12 degrees when you can just alter the entire planet instead.

Like reducing the number of cars.

Ohh too much traffic! 🤔 Let's expand the freeways until you need a freeway to cross other freeways.

Twelve degrees what? A degree Celsius is more than twice a degree in Fahrenheit.

State your units, FFS.

[–] [email protected] 13 points 2 months ago

I will assume celsius since the IR image shows around 45 and 35 degrees in direct sunlight.

Considering it's no an American brand I'd say Celsius

wouldn't this also work on buildings? pavement?

No, only Nissans. It says right there.

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

Can they develop a paint that reduces the amount of cars? That would be more helpful.

[–] [email protected] 30 points 2 months ago (2 children)

This might match your criteria:
An image of a car painted in army camouflage

(Jokes aside, I do agree with your sentiment)

Why did you post a picture of an empty street?

[–] [email protected] 9 points 2 months ago

I don't understand, why did you post a random picture of some pavement ?
