Nissan develops paint that keeps cars cool in summer heat (www.asahi.com)
from lemmee_in@lemm.ee to technology@lemmy.world on 28 Aug 2024 06:33
https://lemm.ee/post/40848699

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.

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.

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?

Sorry can’t find it, all I can find in english are some where the data isn’t clear.
If a white car has brighter interior it will stay slightly cooler, I cannot find a test where everything is the same except the color of the car.
What I can say however, is that the test I saw was performed in Denmark. It’s possible countries with hotter climates may observe some difference?

Obviously the main source of heat is what enters through the windows, and how much is reflected out again does have an influence.,

If a white car has white seats and interior, they will obviously not heat as much as black seats and interior.

The white color on the exterior will also reflect more light into the car, except maybe at noon.

Edit PS:
I linked the danish test in a new response.

Konklusionen er altså, at den sorte bil ikke varmes mærkbart mere op end den hvide.

Translation:
The conclusion is that the black car does not heat up noticeably more in the sun than the white.

So it does a little bit that you can measure, but not enough to really make a difference.

Det skyldes ifølge Christian Bahl, seniorforsker hos DTU Energi, at bilerne opvarmes gennem ruderne.

According to Christian Bahl senior researcher at DTU energy, that is because the cars are heated through the windows.

But to your point about travel, that isn’t analogous. This isn’t an American tourist going to another country, where the temperature context is Celsius. This is an article disseminated globally; by its very nature, the context should be agnostic of locale, and so it would behoove the authors to be clear (again, with a single letter) so that there is no confusion.

Anything on the internet is inherently accessible globally, unless there's a geo-block in place. That does not mean that the things on the internet have to inherently be tailored to US standards or with US viewers in mind. The clearly not US sounding website "The Asahi Shimbun" even specifically has the subtitle "Asia & Japan Watch", which should make it more than obvious that this is not a US focused media. The only confusion coming up here is when you have to assume US units being used everywhere else, which simply is not the case.

It’s not even necessarily a US centric view asking for it - taking the high road here: anyone in the US interested in science is used to seeing both common and metric units. it’s really no big deal to switch back and forth.

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.

Yes, just like "rock / gravel gardens" or whatever you call them in English, which are now banned in a lot of places for one reason being that exact same phenomenon of contributing to the urban heat island effect. They soak up the heat from the sun like a battery and then slowly release it into their environment, keeping it warm. It's super obvious as a pedestrian.

You realize the emissions saved from reduced AC usage would also reduce the heat island effect, right? Sun visors like this are good for public spaces.

Is metal paint and concrete paint the same thing? I’m not a painter

XeroxCool@lemmy.world on 28 Aug 2024 16:51 next collapse

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.

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.

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.
