[@colleenforrest7936]

This is so cool. Got me thinking. Could be why temperatures are cooler around plants, too. They reflect the green light so there is more free green light in the vicinity to evaporate water in the air. Maybe the evolution wasn't just to conserve water for the plant, but a symbiosis between the plants to keep each other cool.

[@geemy9675]

-clorophyl does't evolve theres only two types a/b and they have been the same since...a very long time ago -photosynthesis uses 1/ red and blue light 2/water captured by the ROOTS 3/ C02 from air and it produces 1/ carbs that store energy or let the plant grow 2/ O2 released 3/ the green light not used is reflected -leaves have "pores" that can close to block C02 and stop photosynthesis if the plant lacks water so if plants could evolve to process green light they would probably do and would have darker, less colorful, almost black leaves and would grow faster/require less light. light is a scarce ressource in dense primary forest and creates strong competition between plants to grow quickly and reach rhe canopy. plants able to process green light too would have a buge competitive advantage. if dew is on the surface of the leaves it has more chance to be evaporated by the white light from the sun + green light reflecred ny the leaves

The exact mechanism was not studied but the effect was identified. Good to see this is all tying back to the fundamentals

Why is MIT so slow, or am I showing my ignorance? As a retired Professional Brewer, we've known about this for a long time. We just call it "Sun Struck". How to evaporate without heat - Only Photons from the Sun. Heineken beer is notorious for getting "Sun Struck" and evaporating a Skunk Sulfur smell without heat. This is why most beers are bottled in a dark brown bottle to filter out all sunlight aka: Photons. But now Heineken is known for their green bottles and refuses to go to brown bottles, even if it will get rid of the Skunk Problem. But that's another story... From a Retired Professional Brewer here in Las Vegas, Cheers...

[@user-tx2nv1rb9k]

Yes this has been discovered VERY long ago!

Chances are the effect is negligible and can only be seen because the technology is accurate enough to measure it. I don't see it changing any industrial process, but if it has an effect on weather forecasting, it might still be very useful.

That's what's most fascinating about this! It's not even a minor effect, it's just small under sunlight because only a small fraction of the spectrum is green and the light is randomly polarized (or unpolarized, which is the same thing). I think it's one of the best discoveries since stuffed-crust pizza.

[@matwyder4187]

Now guess how long it will take this to be presented as a rock solid counterargument to the greenhouse effect and climate change in general, because SEE we don't understand it AT ALL - that kind of ignorant bs is already on the way. Now to be honest this is agreeably a bit concerning, if there's even a 0.1% difference in the effects of solar radiation to what was understood before, that can quickly accumulate into massive divergences in the applied models, so yeah, what the hell.. Is this really a brand new discovery in 2024? Also seems to be not too subtle, so after decades of precise measurements, how such a thing gets missed for so long?

This (the video topic) is not sublimation. This is a light hitting the surface of the water causing the formation of a mist (i.e. tiny droplets of liquid water) which drift off and later evaporate in the air. The higher rates of evaporation here are not really anything special it is just a result of more surface area and interaction with the air. You would get a similar effect agitating the water in some other way. They just happen to be doing it using light here.

But what is your point about the very basic pV=nRT? How do you figure that Ideal Gas law applies to a polar opposite situation, namely, Phase Change?

[@ipp_tutor]

That is a very valid question, and I’ll try to answer it as best I can as a professor of thermodynamics: What you’re referring to about water vapor pressure is related to something called spontaneity. Water’s vapor pressure is the pressure of gaseous water you’d need in the air for both liquid and gas to be at equilibrium, in other words, for evaporation and condensation to balance each other out and for the bulk of the water NOT to evaporate. When the pressure of water molecules in the air is lower than water’s vapor pressure for that given temperature (which is the pressure differential you’re talking about), the bulk of the water will spontaneously (naturally) evaporate until the air is saturated with water (the pressure reaches water’s vapor pressure), or until it completely evaporates. In short, water (and all liquids and solids) is always evaporating and always condensing. The pressure differential only tells you which of the two processes wins over the other and whether you see a puddle dry up, get bigger, or simply stay as it is. This discovery is about HOW water evaporates, not about what happens when it does or in which way the liquid-vapor equilibrium tilts. That’s why no one is talking about differential water vapor pressure. I hope that answers your question.

[@ajhubbell3754]

While heat and (apparently) light can cause evaporation, water evaporates in the dark and cold as well. Water can even evaporate while frozen as ice…it’s called sublimation.

[@yikwanwong8267]

[@0ctatr0n]

Makes sense, this is why shade from tree cover is so good at maintaining moisture in the soil. Also explains why all plants have a green colour, to reflect the evaporating light back!

[@cswservices2240]

Also mowing the grass taller . If an area is too wet we mow it shorter. If it's very sandy soil we mow it at least 3" to help keep the water vapor in the soil.

[@tcbraz]

Well bless your heart ❤. I guess any color other than green would dry out the leaves more quickly.

[@incognitotorpedo42]

I think the green color has more to do with the absorption spectrum of chlorophyll. The job of the leaf is to reduce CO2 to more energetic molecules like sugars. The chlorophyll absorbs blue and red light, leaving the green light to be reflected, so the leaf looks green. The absorbed photons provide the energy to run the process of photosynthesis. Since there's not liquid water on the surface of the leaf most of the time, I doubt the photomolecular effect is doing all that much to cool it.

[@tsraikage]

tree shade is trapping moisture because there's not that much energy input compared to lit area. red beach umbrella will have the same effect. plants are usually (but not always) green, because genetically its more efficient to evolve into something that matches quantum efficiency of photosynthesis, more electron transfers happen in the blue and red frequency bands just due to energies involved in excitation of electrons in carbon dioxide and water bonds. carbon dioxide's excitation peaking at blue color and water's at red. if simpler genome has same fittness, it will reproduce more just because it needs less resources. I'm pretty sure you've seen more than negligible amount of red trees with same if not damper soil underneath them just because more reflection in close infrared band, to return to the first idea. but cool study indeed.

❤I studied with Horace McCracken in the late 80s. He was a champion of solar water distillation. I own one which has seen continuous use for 30 years. There are no filters and uses sunlight and the photo molecular effect to cause water in a shallow trough the vaporize and condense on the underside of shower door glass. It makes RO quality water with no filters. There is a fill up irrigation valve which lets in a small amount of water every night. A overflow lets out the excess. This makes a 2-3" shallow pond of water. This all makes perfect sense. Sunlight is very reactive and interacts with anything exposed to it like my skin! Beautiful work to discover this photo molecular effect I knew it could not be heat alone which makes a solar still work so good!

I’ve long wondered if, in the long stretches of undeveloped land in CA, they could create long (switchbacked) solar still type water troughs on the valley side to desalinate agricultural water. Pump (slightly inland for sand prefilter) ocean water up the mountain into one trough with a clear cap (this video suggests it should be a polarized cap that condenses into an adjacent trough. Have a couple iterations if need be. Truck or pipe the excess brine back over or through the hill, collect the evaporated water for agriculture. There’s lots of hilly land with lots of sun and the biggest cost is probably pumping the water up & a return for the brine. Aside from the pump nand an occasional scrub down, it’s filter free with no moving parts and low maintenance.

Tbh the entire thing is basically "oh hang on, we found another discrepancy between our model and reality". That's all this "maximum rate" really is. It's not even about the model that describes the basic process, but about an applied spreadsheet. The assumption in the applied model was not entirely correct. Whoopteedoo. As for the explanation, liquid water is not a rigid unmoving structure, and the overall rate of evaporation in general is a balance between rates of evaporation and condensation at the surface, plus more distribution shenanigans at the boundary area. So basically the whole explanation shows why we don't often hire US students for hard science.

[@peterpoulsen8061]

I learned in school, and has observed myself how ice/snow can go straight from solid to gas phase - even at night. So the MIT discovery must be an addition. Water doesn't only evaporate due to heat. All molecules try to obtain a balance reaching a certain saturation in oaetial pressure.

[@stefanweilhartner4415]

ideas: * it could make wet coating of battery cells more energy efficient because the solvent needs to be evaporated after coating the surface with the black slurry. * if there are two different liquids like alcohol and water to be needed to evaporate (destillery), but not at the same time, the photomolecular effect could be a better way of separation by finetuning the wavelength to a different molecule. this for me would be the real game changer because it goes beyond just saving energy, it might offer you a new function/tool. * improving the efficiency of water electrolysis but you probably need higher frequencies which means a shorter wavelength to help breaking up the bonds between oxygen and hydrogen. the resulting effect might be a cooler H2 gas which saves you more energy in cooling/compressing. on the other side, hot water might not need that much extra energy to be split up in H2 and O, so when compressing hydrogen in tanks, you could use the resulting heat to heat up the water.

I agree.... you cannot understate the economic impact to manufacturing. This is a multibillion dollar discovery.

the solvent is different from water, the photon basically rips the bond between the rest of the water with high energy, like twisting a water bottle and shooting it makes water vapor, the photon ripping it so fast causes it to evaporate, which means this most likely wouldnt work on highly structured compounds like a solvent. unless its alcohol, just blow hot air onto it from your mouth will do the trick.

Yep, water does not care ithe energy comes from heating, or from hitting ;) hitting it with a photon.

[@MisterRockAlot]

Theoretically if one had really small hands, they could grab these bundles of water-molecules themselves and throw it up in the air.

[@chrisfleischman3371]

It can even come from kinetic energy. Cigar stores have rooms where fans slam air molecules into a container of water. The air has sufficient kinetic energy to break the surface tension of the water and to force it upwards into the surrounding air.

[@ehombane]

@@chrisfleischman3371 Absolutely. drying my bathroom (sometimes full of wet clothes lines) is the most efficient when I put a fan in there. I have a fan in the wall pushing out the moist air, but that air flow is to small to be of huge help. The big table fan flapping the clothes around does the job ten times faster. But is ten times more powerful. So in the end the question is about how much energy requires every method? boiling?, filtering, or evaporating with wind light or whatever. By now the filtering, I mean reverse osmosis, at large scale is quite cheap. I hear that is 50 cents per ton. In my region the official price of water is about ten times higher, even the water is collected from a river and filtered with standard method, like sand filters, and chlorinated. So, in the end, here making the water cheaper for the consumer is about better administration, not better technologies. I mean getting rid of corruption. So yeah, new technologies may be just interesting and fun to discover, but not so helpful unless are really huge breakthroughs.

When I was in school back in the 1970s, I asked my teacher if air movement made water evaporate and he told me that water didn't need air, heat, or light to evaporate. Water evaporated even in a vacuum, even when cold (with even frozen water sublimating under low pressure), and even in the dark. Apparently, he was decades ahead of the "conventional wisdom" you described here?

[@GeoffInfield]

Exactly, heat was the obvious one but my school also taught that lowering pressure (which reduces temperature) absolutely vaporises water! Ask a cloud .

[@pariahzero]

Those properties of water were well known by the 1970's. Freeze drying depends on evaporating water in a cold vacuum. The Inca freeze dried potatoes as far back as the 13th century, and modern freeze drying to the 1890's. And that's just freeze drying - our understanding of that bit of water's behavior is even older. The great problem with "conventional wisdom" is that the convention is we reward ignorance and showmanship over facts and careful research.

[@BioTechproject27]

yes, all substances do that. As long as the whole system has enough energy to knock a single molecule off (minus a bit of quantum tunneling), it will do it at some point (although ofc the probability of that happening is low then). Even nuclear fusion happens at ambient conditions and even near absolute zero, but ofc it's incredibly rare then. Heat helps increase the probability (in both cases, evaporation and fusion). Ofc, the higher the temperature and lower the pressure, the more likely a molecule is to break off. The less molecules are directly above the surface (being able to condense), the more likely the substance is to evaporate faster, where air movement comes into play. (Liquids are always fully saturated just above their surface, so removing that layer is key in fast evaporation)

It's very important to notice that the molecular weight of water is substantially smaller than the molecular weight of the gases in the atmosphere. It is already remarkable that water is a liquid at room temperature. This suggests that you don't really need much energy to liberate water molecules from their aqueous environment. You just need to disrupt the hydrogen bonding in some way.

[@gonegahgah]

Water has a molecular charge orientation which makes it align in a very strong way. This makes it denser than air which compared to water is more charge balanced in relation to its peers. Denser of course means it tries to push lower in the gravity field. But, that is an interesting observation none-the-less.

I believe there is additional energy needed to heat the water. It will be cooling while the laser evaporate the water. The air cools then that also cools the water. 9:30

[@peglor]

The uneven charge across the water molecule causes the molecules to bond together far more strongly than molecules with a similar atomic weight but more even charge distribution. The OH group that defines alcohols also creates this dipole, keeping alcohols liquid at room temperature too. Water requires a huge amount of energy to evaporate (It take far more energy to convert a kg of water at 100 C to steam than it does to heat the same kg of water from 0 to 100 C). That's why steam is such a good way of transporting heat energy for power generation.

In a related matter, I've often wondered why cool humid air feels colder than dry cool air - while warm humid air is the opposite. I speculate that near the freezing point, many of those clusters are actually ice clusters, and it takes a lot of heat energy to melt and vaporize the clusters. Regardless, I think water vapor in cool air is in the form of tiny, tiny water droplets and it takes heat energy to evaporate them.

[@riderpaul]

Another advantage seems like it could work on flowing water since the light is targeted on the molecules it interacts with at the surface, whereas heat needs to dissipates throughout the bulk of the water before evaporation can reach its equilibrium. This also implies that the initial energy savings is even greater.

[@bobbun9630]

Plants have other means of protecting themselves from evaporation, such as waxy coatings on their leaves. The ancestors of plants also evolved in the oceans where evaporation wouldn't have been much of an issue. A more widely accepted idea for why plants are green is the Purple Earth Hypothesis. The basic idea is that photosynthesizing organisms that use chlorophyll evolved after and had to compete for light with earlier organisms that did absorb green light (and were thus purple). We don't see that state of affairs today because most of the purple photosynthesizers were killed off by all the oxygen that chlorophyll-based organisms eventually produced.

You failed to take into account sublimation. Notice the effect of meat drying out in a freezer. No heat or light is needed. When the vapor pressure of water is higher than its surroundings it continues to evaporate until it reaches the saturation point.

You missed the fact that large scale desalination of water is done in the absence of air. The water is vaporized to separate it from the nonvolatile salt then the vapor (steam) needs to be re-condensed. This new process appears to be more of a microscopic mist generation (like a nebulizer). This mist is generated in a subsaturated atmosphere of air and the micro droplets are further evaporated by drawing heat from the air. Without air it does not work.

[@heinpereboom5521]

You are right, for example the evaporation of water in a pond in the summer is most dependent on the relative humidity and of course the wind speed. Here too, the vapor pressure is an important factor in the same way and only a higher temperature has less effect. I would like to see the experiment showing that photons alone make the water evaporate much faster, so how exactly did they compare this evaporation. This man says that with the same amounts of energy of light compared to "heat", the water evaporates 4 times faster. If you want to evaporate 1 liter of water on a stove, you would have to compare that with photons that hit a very large surface of water. Photons have much less energy per m2. I'm curious what this experiment looked like.

[@beargiles4062]

I thought the general idea was known for some time - I remember watching a documentary on climate change and possible causes besides human CO2 emissions and one of the data points was records of how much water was added to the water basins on ranches. I think these basins were only used to monitor how fast the water in basins used by the ranch animals would evaporate. The ranchers would know how much water the herd would consume (given weather conditions) that would help them avoid having those basins run dry without requiring someone to physically check the water levels several times a day. The ultimate conclusion was that the evaporation rate had dropped over the last few decades, when adjusted for temperature and humidity. The conclusion was that there's been a subtle increase in high, thin clouds that reduced the amount of UV light reaching the surface. That light could break the bonds between water molecules. So thin clouds, barely visible, reduced the UV hitting the surface. That reduced the evaporation levels, and that in turn meant that the ranchers had to add less water. Those thin clouds were probably created by humans, e.g., perhaps from aircraft contrails. (We know that's a factor after air traffic was shut down after 9/11.) (We also know that the dirty fuel used by merchant ships was a huge factor after its use was banned a year or two ago.) Of course knowing that green light is enough, or that polarization is involved, is a big leap forward. It's one think to know that this happens with UV light, a very different thing knowing that it happens with relatively cheaply produced polarized green light.

[@peglor]

The efficiency issues with steam power pretty much all lie in the conversion of the energy in the steam to useful energy like motion or electricity (It's still the best option we have, but the Carnot limit sets an absolute limit on the efficiency with which the energy in the steam and be made into useful work). The steam needs to enter the system with the correct amount of thermal energy and since this new discovery doesn't contradict conservation of energy, there's no reason to think it has any chance of being more efficient than the 90+% efficient boilers already in use.

[@tonygee5087]

It's absolutely not true that you must have heat for water to evaporate. Who told you that? It is true that adding heat to liquid water will cause evaporation in an open system, however, I can dry my clothes at night when the temperature is dropping i.e. declining heat so how does this happen? All liquids have a partial pressure equilbrium so when you have cool dry air this will draw water from liquid to gaseous phase until the partial pressure for that temp is reached which will never happen for clothes in dry air to they complete dry out. This is also why your food dries out in the refridgerator if you don't cover it. Yes, I'm just a dumb high school science teacher, but water can also be "boiled off" with electromagnetic radiation, specifically microwave radiation and this is how your microwave works and once again there is no actual heat applied to the water but rather radiation. I never heard anything about the quantum magnitude of this socalled photoelectric effect but it supposedly might be used for all sorts of amazing stuff. There are all sorts of weird phenomena but their net effect is so low or so energy inefficent that it is nonsense to even think about it as the basis for practical use and perhaps this is the case for water photoelectric effect? Unfortunately a lot scientific papers these days are more spin than science and it's the questions they don't ask that is the problem especially because they are often looking for funding to spin off the tech or on sell it so their "research" often is more like a startup blurb - and I say this having worked a very long time in Uni research earlier in life.

[@ChrisJones-xd1re]

Green light evaporates water more? Is that why plants went from wine-colored leaves to green? The old explanation is that there is more green light, so plants that didn't reflect it died off when the climate got too extreme. But this never made much sense to me, since the light that reaches Earth is clearly more yellow. But if green light is itself, regardless of how much of it there is, particularly harmful in that it might dry out foliage, then selecting for green reflectivity works, even in yellow -dominant light.

[@Bobster986]

This whole theory sounds like a setup to me.

[@Obsid_Ian]

Speaking in plain English; as a swimming pool builder I can tell you that water evaporation is worse on a windy day and not a sunny day. Now, I'm no scientist but I do understand why rain clouds are formed over the ocean and dump on land. Plus, many of my clients with new pools ring me to say that their pool is leaking because they don't understand the effect wind has on a pool even in winter.

[@cam1king488]

This is due to a phenomena that the video seems to disregard, which is diffusion. They are frequently thought of as the same thing, but are completely separate

[@LZRCuteR]

@Obsid_Ian well, now youre bringing in turnover. Same effect as dropping the water through air. When you turn the pool over by blowing wind over it your encouraging heat transfer by convection. It increases the effective surface area of the pool that's feeling the effects of the atmosphere, be it hot or cold. It can heat or cool a pool or vessel faster to spin the volume over horizontally in such a manner.

[@Obsid_Ian]

@@LZRCuteR you appear to know what you are talking about so I have a question for you. I've got a 12m infinity knife edge on my own pool and I'm well aware of the additional evaporation that is created since it drops more than 1.0m however, why does the water movement increase the volume of acid required to maintain the pH?

[@LZRCuteR]

Hmm, i think you're asking why doesn't the water that the float valve replaces reattach to all those acid ions that were once muriatic acid, reforming it....where does the acid go? Well, it goes into the microbes and fungus and algae, all those organic and it kills them, remaining in their corpses until they finish decomposing in the sand filter. It goes where it's supposed to go to keep the pool suitable for human use. I come from a line of Chem Es, And we all love pools too.

[@LZRCuteR]

@Obsid_Ian what I'll think about for a minute is how increased evaporation that Isnt replaced by the float valve might affect acid. Any acid that doesn't go into microbes or all kinds of substrate in the pool, living and inorganic, should generally lower the pH below desirable....but that is fine to a degree, you just don't add acid that week until the float valve raises pH slightly. But missing acid...let me think about that. We've gone "missing" acid in lots of industries I've worked in, so it should come to me
