New Spray-On Coating Can Make Buildings, Cars, and Even Spaceships Cooler (bgr.com)

Long-time Slashdot reader davidwr and Iwastheone both submitted this story about "a paint-like coating that facilitates what is known as 'passive daytime radiative cooling,' or PDRC for short...when a surface can efficiently radiate heat and reflect sunlight to a degree that it cools itself even if it's sitting in direct sunlight." BGR reports on research from the Columbia School of Engineering: Their newly-invented coating has "nano-to-microscale air voids that acts as a spontaneous air cooler," which is a very technical and fancy way of saying that the coating is great at keeping itself cool all on its own. "The air voids in the porous polymer scatter and reflect sunlight, due to the difference in the refractive index between the air voids and the surrounding polymer," Columbia writes in a post. "The polymer turns white and thus avoids solar heating, while its intrinsic emittance causes it to efficiently lose heat to the sky."

It sounds great, but the best news is that it can be applied to just about anything, from cars to spaceships and even entire buildings. The team believes their invention would be an invaluable resource for developing countries in sweltering climates where air conditioning is impractical or unavailable.

It's better in that a white surface doesn't radiate much, so even though it reflects most of the energy that strikes it, it still heats up. It's worse in every other way. These nanoscale structures are always fragile and turn into nanoscale dust, and which don't break down easily (because of what they're made of) which makes them persist in the environment. Auto paint is expected to last for decades in harsh conditions, but they gave that as an example anyway.

Re:It's called "white paint"

I've done a lot of roofing in my life, one type being a rubber roll that gets melted down with a propane torch for flat roofs. An aluminum coating in a can needs to be applied to the rubber roof in order to reflect the ultra-violet rays of the Sun. If this special coating isn't applied, the rubber rots away within 5 years. Reapplying this silver coating every 5 years can almost indefinitely extend the life of the rubber roof. Does this material do this also?

Re:It's called "white paint"

[hankwang]

In thermal properties it's not different from most other white materials or white paint: they absorb and emit well in the thermal infrared range (5 to 15 micrometers) and reflect well in the visible and near-IR (400 nm to 1500 nm). Even plain white paper would do the job. The effect of this fancy coating is possibly a marginal improvement in the 1500-2500 nm range, but sunlight does not carry that much energy in that range.

The opposite is much harder: absorb sunlight but don't emit or absorb thermal infrared. That's what you need for solar water heating. It can be done (silicon layers on top of reflective metal) but it is expensive and sensitive to contamination.

Re:It's called "white paint"

Re: It's called "white paint"

[popoutman]

Things dropping below ambient air temperature is extremely common. The simplest examples would include nighttime ground surfaces when the sky is clear. There's a reason why the edges of fields and the areas near walls and trees is the last to get frosted up

In essence, the temperature of an object depends on the heat transfer between itself and its surroundings. This transfer can be of conduction, convection, or radiation. For objects that are not fluids, that is limited to conduction and radiation. Now, air is a pretty good insulator and a poor fluid for the transfer of heat. Noting that the effective temperature of a clear sky at night is in the negative 40 degrees or lower, it then becomes fairly easy to see that the object in question will radiate a lot heat in that direction without a balancing flow of heat back. If that object were in an enclosed room, then the room surfaces would be transferring heat to the object at the same rate the object would be transferring heat to the surfaces - no change in temperature. There is heat transfer between the air and the object by conduction, but that is a very inefficient process by comparison especially when the air is still - and heavy frosts happen more easily with still air.

Telescopes can regularly reach a few degrees below ambient and then become cold enough for dew to condense on the optics and the tube structures, because the optics can be exposed to the cold sky and the optics are not being warmed effectively by the surrounding air.

Whether one can power a steaming engine with that, well if you have a working fluid in the right temperature range of course you can. The available power though would be very small given the delta-T present. It may be possible to measure a voltage with a very large Peltier setup sinking heat by radiative cooling only, but not enough current to be practical and especially for the cost of setup..

Theoretically this would be a version of Solar, where daytime heating and night time cooling is the driving force.

Useful in the Developed World

[mykepredko]

I would think that this coating would be useful in the developed world where a coating like this would reduce air conditioning requirements for homes and buildings.

The biggest issue would be that the buildings/cars would become a lot more whiter and I suspect more blinding in direct sunlight.

Re:Useful in the Developed World

[Mr D from 63]

Questions that come to mind are "how much emittance occurs which there is a high delta-T? How long does the coating last and how easily is it's emittance reduced by normal environmental conditions (dirt, microbials, etc)? How much would it cost? Any toxicity concerns?

Re:Useful in the Developed World

[drinkypoo]

and when winter rolled around, my ife started claling them "you stupid windows" because the house didn't warm as fast in the morning

There are two separate considerations when selecting windows, R-rating and E-rating. Multiple panes raise the R-rating. Coatings lower the E-rating. The E-rating measures how much non-visible light passes through the glass. Passive solar designs use glass with a high R-rating and a low E-rating, meaning that they don't let as much heat energy escape by conduction, but they let solar energy enter via radiation. And they use overhangs or awnings to prevent that from happening in the season when the sun is overhead, but which permit it to come in during the cold season.

Re:Useful in the Developed World

[DCFusor]

Yup, we need things like that to be reversible. It really matters here as I'm off-grid so heating and cooling have to mostly be non-electric. An amount of solar that lets my keep my Volt charged up (mostly) won't do the HVAC kinda stuff...that's wood, propane, and mostly small fans, only a little AC. And it does get hot here, but also spends time around 10F. Lots of degree-days.

Re:Useful in the Developed World

[White Yeti]

Agreed. Unless it works under a clear-coat, the normal progression of house paint along the Gulf coast is white--> green--> brown--> powerwash--> beige -->repeat from green.

Re:Useful in the Developed World

[Anonymous Coward]

The higher the temperature gradient, the better it works. We were running a steam engine using this coating boil water by cooling the condensate. The coating melted when we reached 1800F. While the steam engine was producing a few megawatts of energy, unfortunately most people are not comfortable living at these high temperatures, so I don't foresee it having any practical application.

Re:or use better building materials

[Aighearach]

The part you missed about the story of the three little piggies; their economy wouldn't support a brick house for all three. It isn't a story about smarts, it is a story about the difference in outcomes according to resource access.

The thing about "compressed earth blocks" is, they're not bricks. As you noticed when talking about clay. Instead, they're something that can be made from a much wider range of input materials. That means that production can be scaled without boosting the price by competing for raw materials with all the other construction technologies. Clay is sometimes locally plentiful, but not compared to dirt. And the main other input is electricity, so you could have a giant factory in an arid region with lots of solar generation, and just run the machine during peak daylight.

You could build a factory in a poor country, and the people could actually use them to build houses. If you build a factory making clay bricks, those have more export value and somebody will get rich, and the villagers will still only have grass huts, or scrap and tarps, as the case may be.

Re:or use better building materials

Earth bags can use an even wider range of soils, and use minimal materials. They do require that you come up with some burlap, and ideally barbed wire as well (to run between the courses) but they don't require compaction, just bag-filling.

Any concerns about nanoscale particles?

[Aristos Mazer]

How well does this paint clump together? As a spray, it seems likely that some of the particles would linger in the air. Medical researchers are still trying to get a handle on the risks of nanoparticles to living beings -- we just aren't made to filter stuff at that level because its not common in the natural environment for there to be free-floating bits at the nanoscale. It might be safe, but we don't currently know. Here is one report from the UK government just listing the research unknowns about nanoparticle exposure. Before we start spraying whole buildings in stuff like this, we should know the environmental and health impacts. I hope the inventors of this stuff start working on those questions before they try to productize this.

Re:Any concerns about nanoscale particles?

[Anonymous Coward]

When looking up safety info on nano-lubricants, they're usually in a carrier liquid and once they carrier evaporates, the nano-particles cling very strongly to whatever surface they're on. If you get the pure powder, while the particles are non-reactive, they can cause irritation to eyes and lungs. I've seen a lot of youtube videos manhandling these powders, touching with bare skin, no breather or eye protection and they claim to do it all the time without issue.

reciprocity, emissivity reflectance

[goombah99]

This is a tricky point of physics which is seldom explained well, and I don't understand it much more than the basic idea. But in nearly everything emissivity at a given wavelength is the compliment (1-x) of the reflectance.

It's a frustrating idea because it says that while white can keep the sun off you (reflecting) it also doesn't radiate either keeping you hot.

Now the escape clause here is that if you are not as hot as the sun, then your black body emission is in the mid IR while the sun is peaked in the visible. Thus if you can make something white looking in the visible but black in the Mid IR it can beat the system and help cool by both reflection of the sun and thermal emission.

Now this device seems to be arguing for something different it sounds like they are saying they use a dark (emissive) material but then make it so granular and scattering that it looks white (which indeed is why clear crystals look white when you powderize them (e.g. sugar).

But my understanding of this, possibly wrong which is why I'm asking, is that it doesn't matter why something looks white to the emissivity/reflectance relation. If a nominally black material "looks" white to the eye then it's going to act identically to an object that is actually pigmented white. It doesn't matter if its refraction, reflection of pigment that causes it to be white. White is white.

THus the explanation seems like B.S. However it still might be working just fine for the old boting reason of being a mid IR black object. that just would not be news.

The reason I'm wobbly on this is when you think about absorbption down at the atomic transition scale then the whole emissivity, reflectance thing gets confusing. It becomes unclear how discrete spectral lines actually add up to that. It's much easier to treat the relation at the macroscopic black body level.

SO is it really possible for this nano scale voodoo to do something other than white paint does?

Re:reciprocity, emissivity reflectance

[Ramze]

I've been reading about this daytime cooling through infra-red emissivity to space stuff for a while now. The biggest benefit isn't the color (or the reflective value), but that it will absorb heat from whatever the source and radiate that energy away in the mid-IR band that will allow it to leave Earth's atmosphere without being re-absorbed by anything nearby. That makes it effectively a way to remove heat from the surface of the earth by emitting that energy into space.... heat that would otherwise be trapped by our atmosphere's greenhouse effect.

This is the first time I've seen this expressed as a coating for everyday consumer items rather than as a heat sink layer added to an exterior A/C unit or a potential roofing material, though.

My understanding is that generally these coatings are white in the visible spectrum to reflect sunlight, but emit light in the mid-IR range. There's a startup company for using this to improve efficiency in A/C units I read a while back, and they tested the material in the hot sun on a roof in India -- you could put your hand on it after it had been baking in the sun, and it was cool to the touch. That's relative term, though. I don't recall the actual temperature readings.

Re:reciprocity, emissivity reflectance

[Anonymous Coward]

absorptivity = emissivity

A quick google turns up this is called: Kirchhoff's law of thermal radiation

Supposed a surface can absorb less thermal radiation than it emits. Put two surfaces, one of this material, and one of another material so they are facing each other. At steady state our special material will be cooler than the other material - because it emits more energy, until it cools enough that this emission decreases to be the same and energy it is absorbing. You could then theoretically run a heat engine off this temperature gradient and extract unlimited (perpetual) energy.

You are 100% correct

[Anonymous Coward]

This is just the usually white paint keeps it cool. They just use $10 adjectives and make up some fancy sounding nouns.

Here's what actually is useful, though not new, in their system.
1. They can take a black (emissive) material and make it white in the short wavelength band by foaming it at a certain length scale so it scatters a lot in the short wavelength range but looks homogenously dark in the long wavelength. This isn't a new idea but is a new material and manufacturing approach

2. using scattering rather than pigment means that it will be white everywhere since it's physics not chemical spectroscopy. Hence it's uniformly white. Pigments can age or have dark spectral regions making them less white.

That is exactly what you said! I used $5 adjectives and you used $1 ones. But we both just said the same thing as the article did.

However the reason we use paint isn't jest because it's white. We use paint because holds up to the UV and rain and bonds to the surface. Paint is basically titanium dioxide, glue, and some rubbery sealant. Those mechanical and spectral properties are what give it durability. Many polymers degrade when exposed to UV or acid rain.

Additionally when this stuff gets dirty it's no better than white paint! but since it's tectured it might not clean up as well as white paint. So it may be ruined by acidic soot found in cities

But it isn't Chris' fault if he is the way he is. We do the best we can do with him and he is partially integrated into society. We try to cure his abnormal need for attention but he is kind of stubborn and won't listen to anybody.

Thank You dear users,

Re:Creimer was going to buy some until he

[Anonymous Coward]

Exactly Nancy,

It seems like Chris is a victim here. He keeps on reading those SEO, youtube algorithm, basically get rich quick sites. He doesn't realize that he is the fish for them since they make money off him with their own schemes. Then, he wastes his time trying to implement what those sites suggest and he ends up disturbing people.

I mean, those crooks tell Chris that he has to build personal brands and he goes on the Internet and makes everything about himself public!

I believe we should bring this up at our next meeting. He might not be our only patient victim of such on-line abuse.

What if you paint Fonzie? Whats Cooler than Cool?

[Anonymous Coward]

If you painted "The Fonz" with this paint, would he become even more cooler or would it be impossible for The Fonz to be any cooler than he already is? This question of course applies only to "pre-shark" Fonzie.

Can we have spray-on paint to make builders and cars warmer please?

Don't worry about spaceships, mine is at the right temperature already.

"Free" heat energy?

[Anonymous Coward]

Since the claim is that it cools a surface to below ambient, I wonder if it could be used to passively extract useful heat energy from the environment, on the hot side of a stirling engine or a thermoelectric generator. Shouldn't be a thermodynamic lawbreaker, since it would essentially be only collecting ambient energy and passively radiating IR into space?
