newly invented white paint is so white it reflects the suns energy, no need for air conditioners on new houses

[Chomiq]

The whitest paint is here – and it’s the coolest. Literally.

In an effort to curb global warming, Purdue University engineers have created the whitest paint yet. Coating buildings with this paint may one day cool them off enough to reduce the need for air conditioning, the researchers say.

WEST LAFAYETTE, Ind. — In an effort to curb global warming, Purdue University engineers have created the whitest paint yet. Coating buildings with this paint may one day cool them off enough to reduce the need for air conditioning, the researchers say.

more evidence the world had a chance to survive if we just gave innovation more time. crypto added fuel to the fire we could not afford, and the lack of RnD early on on making cement "green". it's to late for this to matter now, humans had their chance. between stuff like this and the transition to LED light bulbs, etc. humans did have a chance though. that's the saddest part.

We found that using barium sulfate, you can theoretically make things really, really reflective, which means that they’re really, really white

First, let's look at the chemistry:

It's not like that carbon monoxide from the manufacturing is green.

That's my issue with any new technology that will replace something and be more "green"

The albido effect is something that ice does really well to reflect the energy of the sun to reduce thermal absorption. However, in a city or town, the effect would be lessened by the black/grey asphalt of the road and transport systems. The effect would be extremely limited in an urban environment unlike the continuous spread that is afforded by the arctic/antarctic. Worse, as these things tend to ignore practicalities, a pure white reflective substance would be painful for all animal vision that uses daylight. The animal kingdom is not habituated to 100% reflective surfaces, so the potential damage to retinal cells could be considerable.

As much as I'm for a more sustainable planet, 100% reflective surfaces are impractical fort almost all animal species.

LOL, this won't totally fly in Vermont, New Hampshire, Massachusetts and Maine! Especially with how chilly it's been.

We have 4 seasons, unlike the deep-south!

Indiana also has much the same kind of weather as we do.

Just a radiant barrier, also all surfaces do absorb heat

In TX you can have all 4 seasons in 1 Day

This paint is just a tech demo and far from a viable product. The barium sulfate materials needed to make it are mining-intensive and kill short and medium-term hopes of carbon reduction.

And.

I didn't know that about the mining materials needed. Hmm. That probably makes this dead on arrival then. Thanks for the info.

 

[R-T-B]

Just wait until the poles flip and everything electronic dies

Just FYI a pole flip isn't supposed to fry electronics.

Man-accelerated global warming is real, and a major issue.

That is all.

I've lived in New England and the Carolinas. Depending on where you live, both are similar in that Northern New England & the Carolinas have three seasons and a short sampling of a 4th season that lasts about a month.

TX you can have all 4 seasons in 1 Day

same with Colorado

The bigger issue IMO is you don't really want your house to blind you, as well.

Hi,
Yep millions of birds were killed just for wind power

Pretty nice find lynx, very interesting with lots of applications for sure

We had one season in the Pacific Northwest: Rain. Thanks to climate change, we now have another: scorching death.

Oh it does have applications. Just doubtful they'll be for painting residences. You like to view your home without eye pain.

How on earth is that related to what you quoted?

Dont forget the damn light pollution from "green" LED street lights.

Cities should focus instead on removing as much flat concrete pavements that lead to hot spots with +10C temperature jumps. We need more greenery, trees, meadows etc. to help improve air quality and biodiversity.

FYI, if you go shopping for the rain season during scorching death season you can get some good deals.

As someone who loves the stars, I get your point, but I'd rather save the watts and have light polution then use older bulb tech and deal with real pollution.

I expect they could fit some kind of filter if they cared. Win-win.

FYI, if you go shopping for the rain season during scorching death season you can get some good deals.

During scorching death season you can't go shopping: nothing is opened and even your cars AC can't keep up.

Relevant photo may follow of my disgusting family cars dash. Yes that says 118F. Lower lcd, which I think was dying. I was too, so forgive the low effort photo.

Isn’t too much reflection a bad thing? I distinctly remember an ugly looking building in UK that was so reflective that it melted cars on the sidewalk or something.

You're thinking of that fugly skyscraper in London nicknamed the Walkie Talkie, below. That problem was all over the news at the time. Due to its funny angles, it focused the sunlight onto the cars below. I don't know how they fixed it.

I mean, just look at it in this arial shot. All the other buildings have proper angles then in comes this misshapen thing.

thank you. perhaps instead of a housing use case, there are indeed other applications that make more sense for this type of advanced paint. or maybe even a a less white color, than alternate that color with this advanced paint, so its not to overbearing on a house, but still reduces overall costs associated with climate change heat.

it's neither a single one (the vdara skyscraper has the same issues)... I wonder how do such dumb thong even get approved in the first place

anyway they did place some sunshades allover the building if I recell correctly

meanwhile about the news, pretty useless imo, there are solutions but in over 50 years nobody has done a shit

The magnetosphere is caused by the the flow of iron in magma among other things don't you think the fact were having so much tectonic activity indicates something.

Yes, it indicates we have a magnetic core.

We need more greenery, trees, meadows etc. to help improve air quality and biodiversity.

Good call, but we are not adept at living in 100% humidity which is what a forest does to cool the climate in its surrounding.

PS: also fungi. We don't like fungi and you cannot have a wetland without some sort of fungus involved. We like desert poetry more than water on tap. Some of the dumbest ideas I have seen involve rerouting forest rivers into hydroplants without a dam creating drought right on the basin.

I live in southern Vermont, which is like a much less harsh version of Minnesota. (same with being like a much less harsh version of the Dakotas and Colorado)

I mean just like with solar panels, the target demographic for this type of paint varies by region... I think its common sense to just say its not for everyone. Same with solar panels, I don't expect Ireland to become a solar panel mega country... but I do expect the state of nevada to do so...

Mirror is a direct reflection resulting in concentration particularly if concave. White is a diffusive reflection in all directions. I had a super duper white car once, it was painful to look at in the summer time.

 

[Space Lynx]

Does anyone know how to buy this stuff yet? I seriously want to paint like my tool shed and stuff with it. lol

If anyone hears or sees anything about this becoming available someday, please post in this thread so I will get a notification, cheers!

 

[Shrek]

I would like to know how it holds up to weather

 

[GhostRyder]

I mean, its a nifty idea that they made a white paint that's even more reflective. We already saw an experiment like this repainting streets in I believe LA (I am sure it was California, just not sure if LA) and this caused a significant reduction in nearby temperatures including needs for A/C to run in houses during summer. I mean logically lighter colors absorb less heat than darker colors so it would help reduce temperatures in homes.

Anyways, problem with this idea is what are the effects of doing this on a grand scale or even just a single neighborhood? What about keeping it clean, will that require significant time and investment to keep these structures clean for it to work better? How about making it (Based on responses, its hard)? How long does it last? All these things have to be considered and more. Truth be told, I think a lot of people would be smarter just doing very light grays/whites on houses and roofs to reduce temperatures in homes alone. There are always alot more cost to ideas like this that are supposed to help the "climate crisis" than shown.

However, once I again I think its pretty cool!
