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.
And that’s 12 degrees Celsius (21.6 degrees Fahrenheit)! What kind of garbage article doesn’t include the units!?
I agree clarification never hurts, but the entire world except for ~4% of highly entitled population will read that right.
Given that a lot of English language media are either located in the US or target the US market, I’d expect the value to be expressed in Fahrenheit unless stated otherwise.
Original article is about Asia, and Lemmy is an international platform, so neither applies here
I don’t mind some actually regional things presented in whatever system they use in there - although I’d much prefer if we’d all go metric already. C’mon!
The original article is not about Asia, it’s about a technical innovation. Regardless, although we’re on an international platform, it’s easy to see that many topics are US-centered, and many sources too - regardless of the subject.
“Asia&Japan Watch” is right under their name.
This topic is not centered in the US by any metric. It’s just an example of a Lemmy bias.
a lot of English language media are either located in the US or target the US market
or target the US market
So regardless of the website’s name or origin, it could be an English language outlet targeted at the US audience. Which is quite common. Which is why I explicitly added this remark to the comment you initially replied.
So why are we back here? What exactly are you trying to prove? All I said that I’d expect a value to be expressed in Fahrenheit unless stated otherwise. I didn’t say that you should do that, or that’s somewhat objective. I was simply arguing that despite only ~4% of population using Fahrenheit, it has much more influence due to the listed factors.
There’s no need for that attitude though.
The attitude comes from Americans expecting the world circling around them.
The comment asked to list out the units which is a common thing to do. You don’t list out a scientific value without its units. They didn’t say list it out for Americans. Maybe the study was done in the US and they listed it in F. How would you know? So who came in here with an attitude?
No, they converted it to Fahrenheit because that’s what they use & expect to be clarified upon.
No, they first listed the units which is Celsius and then converted it themselves and didn’t excepted it to be converted. No one is complaining that it’s not in F but rather that the units are missing.
Fair, my bad! Sorry if it was offensive.
I just got a little sick of all the Fahrenheit (and also Imperial) domination around here. This, in turn, is often left without clarification, despite the system being way less popular.
Lemmy as a platform is extremely America-centric, despite having tons of folks from everywhere else, which is aggravating in the long run. World really, really doesn’t all revolve around land of the free.
Being from Russia, I’m fine with people using the units they are more confident with or used to.
(Not specifying units may be a bit confusing, but then people here don’t say\write “it’s 20 degrees Celsius” either.)
Russian-languaged media is not commonly consumed by someone living under imperial/Fahrenheit system, so it’s only natural.
For English, it might make sense to at least always add Celsius in parentheses, unless it’s highly regional news.
Also, привет российским леммиводам :D
Превед.
Metric ton of folks or colonial? Please clarify.
I agree though, that’s why I like posting conversions from time to time on other posts that are US defaults.
You’re right. Everything should be in degrees kelvin by default. Problem solved.
I totally agree
Kelvin and Celsius are the same scale with a different zero point anyway.
I will not stand for this! Rankine will be the standard! It will confuse and infuriate everyone equally. Truly the fairest of outcomes.
Why would it be anything else?
It’s clearly too low a number to be °K. And since the only two valid units of measurement for temperature are Kelvin and Celsius, it must be °C.
A differential temperature of 12C is equal to a differential temperature of 12K…… You don’t take the offset into account for differential temperatures.
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.
There probably wasn’t even anyone who actually wrote it. Fed it into some LLM to generate the page and no one actually edited it to make sure everything made sense
How would you know it’s wrong if you don’t know fahrenheit
Fair point, but I guess I would hope that the person being paid to write the copy would check it, since getting that right seems like it’s part of their job description ¯\_(ツ)_/¯
That’s why it’s a better choice to just clearly identify the units and not attempt to be clever about converting for a particular audience
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.
This is a news article, not a study, which would’ve more likely used Kelvin, which would be still 12 degrees. It’s for everyday people, which almost all of which use Celsius to measure temperature. People outside of the few countries who use Fahrenheit don’t get confused about it because it’s literally the only measurement they use in their life. If you travel outside the US you will find that no one adds Fahrenheit conversations anywhere and that pretty much all temperatures are listed in Celsius.
You’re arguing that it’s not worth the effort to be clear over a single letter, from a place of what appears to be some American-oriented xenophobia. Not a good look.
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.
Calling out US entitlement isn’t xenophobia. That self applied victim complex is just proving my point.
This is an article disseminated globally
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.
I’ve definitely seen some non-US news sources convert to US common units based on my locale. I’d much prefer they just clearly state what they’re using, especially like here where it’s just a matter of adding one character - similar to time where it’s adding three characters for the time zone.
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. Just be aware there are multiple possibilities and indicate which you’re using.
Again, you’re quibbling about the letter C for the sake of clarity and calling that US entitlement. You’re welcome to die on that hill, but it seems like a silly one to die upon because you have some beef with Americans.
Again, you’re quibbling about the letter C for the sake of clarity
No, that’s what you are doing. lol I’m telling you that the letter is irrelevant for the majority of people in the world because we all already assuming the correct units of temperature and you seem to take an issue with that fact.
You need the ° or else you’re just making errybody mad. Or maybe that’s just me.
Maybe it’s a mental reading thing. I always “hear” the word “degrees” in my head when I see °, so I like the extra effort to include that, but I also know that colloquially, people are a lot lazier.
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?
🙄
There’s no paint on the planet that will make most of their cars cool.
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?
can i paint my house with that?
Nanoparticle roof shingles are a thing and they really work well
There’s already a 98% paint, not that cheap last I checked though.
That typo reverses the meaning by being one letter off.
Lol
They’re currently working hard for a way to make it subscription.
12 degree °C or °F???
Considering it’s no an American brand I’d say Celsius
°C, which is not bad. Official press release (I think): https://global.nissannews.com/en/releases/nissan-trialing-cool-paint-technology
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.
Hello and welcome. The purpose of this forum is for people to share articles, and then discuss the contents of the article they just read. If that’s not what you’re here to do, please spend your time elsewhere.
LOL I’ve been here for years, I don’t need a welcome, but I appreciate the sentiment.
I will spend my time when and how I choose, thanks so much, have a nice day!
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.

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
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.
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…
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?
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.
I don’t care about your cage’s interior temperature. Until we can ban cars from cities I’d welcome such paint, because all those shit heaps of cages standing on public space still end up heating up the places around them, further inconveniencing everyone else even more.
Do they? I mean yes, because the ICE engines just constantly dump a ton of heat out, but does a parked car? Is there data on that?
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.
Also, it’s more environmentally friendly to have people use visors than repaint their whole car.
That still does not make me care about your cars interior temperature.
That’s okay, you seem pretty simpleminded so I don’t exactly expect you to understand the issue. I understand the anti-car sentiment but you’ve clearly gone off the deep end yet you still seem to think it matters to other people whether you care about issues like this.
That’s okay, you seem pretty simpleminded so I don’t exactly expect you to understand the issue.
Projecting much? Love the insults btw. Really drives your point forward.
I understand the anti-car sentiment but you’ve clearly gone off the deep end yet you still seem to think it matters to other people whether you care about issues like this.
You seem to care a lot. It’s also again projection and highly ironic since you were the one who apparently thought people care about your car’s interior temperature.
You seem to care a lot.
I think you’re confusing my care for the issue as me caring for you. It’s too bad you can’t even be bothered to make some of your comment relevant to the discussion.
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. I thought this was common knowledge as well as many people I’ve met avoid darker colours in summer and such.
What’s the cost (financial and environmental) of repainting a car vs using a windshield visor that’s at least twice as effective at reducing heat? Painting a car with this stuff would cost thousands of dollars compare to $20 for a visor.
I’m not talking about repainting anything, why are you moving the goalposts? Just buy a white car AND use a visor, what’s wrong with that? And in the future, if this stuff is actually good, maybe all cars can come already painted with it?
Summer was hard on me in my teenage goth years.
Can’t really get many light shades of black.
I think i’m in love.
Speaking of huge and inconvenient, if you’re a cheapskate, just get a car cover. Always helped my motorcycle.
I bet the interior of your motorcycle was WAY cooler after that.
It was! Also, the exterior wasn’t too bad, either
Wanna know how you’re right? Look at the FLIR photo above and note where the heat is at its highest
Why don’t they just make the whole
planeplanet out of theblack boxpaint.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
Uhh, what? The problem of things getting hot in the sun?
Blow up the sun. Easy.
I like blowing things up.
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
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
