- In this video I attempt to build an air conditioner out of clay! This is actually a traditional technique used to keep water cool in hot climates, but creative folks today are trying to rework this ancient water-cooling method into passive air cooling systems! The best part about this is they use no electricity, so are a eco-friendly solution to keeping your home cool in summer. Let me know what you think! Would you ever use this in your home?

Such an interesting video. Thank you for the no shade to those of us who use AC. My AC broke a little over 2 weeks ago and living where I do that is just torture. I'll be glad when we get it fixed hopefully next week. I think before those of us with AC can cut back, we need big companies to cut back on what they are doing so the planet can start cooling down, and then we'd all need the AC less. We used to actually have Fall and Winter where I live. Now we just have Summer and Slightly Less Hot Than Summer. I miss snow so much. I really hope we can start reversing what has been done to the planet. Hope everyone is staying cool as they can for now. ♥
you’re so right! 🙌🙌
don't suffer for the elites... you not using ac is doing absolutely nothing when rich celebrities and elites are still flying on private jets. crank that ac up!
Where is this?
Perfectly said!
Can you share what location is that?
Just a couple points about these coolers: Due to the method of operation being evaporation these coolers increase the humidity in the air, this has the effect of making the room feel hotter than it is, and in situations where there isn't much air flowing into the room and there is a lot of heat going in it can feel even hotter than it would have been without the cooler. Another effect is the lessening effectiveness of the cooler itself as both the temperature decreases and humidity increases, eventually stopping to work completely if and when the dew point reaches ambient temperature, otherwise known as 100% humidity. All of that is not to say that these coolers are bad, just that they are situational, and generally they work better outside.
In my city the temperature this noon was 35C with 66% humidity, which would make the dew point somewhere around 26C. This is the absolute lowest temperature this cooler could achieve here, and with the increase in humidity it would feel quite terrible. And indeed when working under similar circumstances and using an evaporative cooler with a massive fan there was barely a difference, even the flow coming out of it barely felt colder. A desiccant based system would work better, but be a lot more complicated to install and maintain.
However, another city in my country regularly sees temperatures of around 42-43C throughout the summer with heatwaves reaching as high as 49C, except with humidity at around 15-20%, which would make the dew point somewhere around 10-20C(it would be closer to 10 in most circumstances). This makes such coolers extremely effective there.
Love finding these treasure troves of information in the comments!
agreed! I live in a dry place and evaporative coolers are really common. Growing up we had one that was essentially a wet bale of hay with a fan behind it - all cased in plastic.
Someone in my city built a wall of stacked porous ceramic pieces similar to this that acts as a water feature on the western wall of their house that gets a lot of evening sun. In this dry city this makes a huge difference to the heat in the room. It does use a fair bit of water though! In dryer climates this can also be an issue (but not a CO2 issue)
Disagree. I am not an expert, but as she already mention it, is the evaporation process that extract energy (aka heat) from the environment. Indeed your are increasing the humidity of the room, but this is not an open place. This is an old technique proven to work. Maybe with a small fan it will increase the circulation of air between the pipes and then make it to work better.
Yup. If your air is full of water then you don’t evaporate sweat effectively. The only time I got heat stroke was near rice fields. The air was very humid.
Great point. These are the equivalent of "Swamp coolers" often used in the dry Southwest of the US. I lived in Alice Springs Australia and whole house evap cooler are the norm. They work well there until it rains and then it's very unpleasant. The user of potable water is also a problem not unlike carbon emissions. The point? Nothing free and we didn't get where we are by accident. It doesn't mean there isn't a different way forward, but if it was simple, we would have solved it years ago.
If you don't use them as AC you might consider partially bury near a tree or plant and using them as a water reservoir for the plants :)
yes I thought the same!!
Or as nest for mosquito
If you fill it with coarse sand, and then water, you won’t grow mosquitoes
It would work better in a window with cross breeze
Like an olla😊
As someone with a science background, my suggestion is to put them on an outside wall like what you show in the beginning. As you have it now, the heat goes from inside the clay (the water) to outside the clay (the room). Currently, you just have water coolers in the middle of the room. If you make the room the inside of the clay, heat will move outside of the room.
Put pipe between that absorbs cool easily and have a fan blow air thru it, the clay cools the water and the water cools the air as it gets pushed into room
Also - The experiment does not really say anything without a control. For all we know, the room could have been 20C or 25C without the evaporators.
You are right and wrong at the same time.
If there is a small air ventilation from outside to the inside and again out, and you emit air with more water vapor than what came in, you are cooling the inside.
If you evaporate in the outside surface, your cooling will dissipate to the outside more than to your room cause the wall acts as insulator.
But if you have enough water to evaporate it would work.
Growing up in Egypt, we used to have those clay jars where water remained cool, despite high temperature. It was so refreshing drinking such cold water in hot summer days, without refrigeration.
How are they called there? We call the "botijos" in Spain.
@@pablosegundogarcia5308 we call them "Olla".. pretty much like the word "Hola" in Spanish, but the H is silent and there is an emphasis on the L: "Ol..La"
Funny. "Olla" in Spanish means "pot".
Although we pronounce "o-ya" not " ol-la".
Thanks buddy!
I know this goes against your "passive cooling" concept, but you could increase the evaporative effect by training a fan on the pottery. As others have mentioned, this concept works very well in climates with low relative humidity. High humidity doesn't allow the moisture to evaporate and the cooling effectiveness is significantly reduced. This exact same concept can be used to make a water chiller (as you mentioned, the water in the tubes gets quite cold) it makes for a refreshing drink! I found this project really interesting!
What an amazing video. I can totally imagine that I would work in dryer climates. Right now I live in Brazil and the humidity is so high, that this will only give more mold but I can totally see it working in more dry climates. Really cool video. Well done!
@@travelingonestepatatime Yep, in areas with high humdity, you get no cooling and it doesn't increase humdity either. You're pretty much stuck with actually submerging yourself in a cool water or drinking cold beverages to remove the heat.
Just placing them in an open window would help circulate the air around them, and more surface area would improve cooling. A greater number of smaller diameter tubes, maybe texture the tubes as well.
You cannot expect a cooling effect the way you envisioned. A/C is essentially a heat pump -- you move energy from one place to another. In your setup you are moving energy from the water to the room via evaporation. This does NOT remove any heat from the room.
What you have made are some awesome water coolers.
This was also my first thought. However, the phase transition from water to vapor does take a lot of energy, so as long as the evaporated water doesn't recondense, this setup should reduce the overall heat in the room somewhat - at the expense of increasing humidity. In other words, some of the heat energy is transformed into latent energy.
Still, it would probably be more effective if the water vapor could be transferred outside somehow, like building this into a wall and wetting only the outside surface.
star max ur wrong
it’s still a heat pump
the condenser just is the entire planet
as the water goes to vapor in the room, it cools itself and it’s surroundings
as the vapor goes to water outside in the atmosphere, it warms itself and it’s surroundings
there’s that heat u pumped out of the room..
@@knutfranke6846 The reason "swamp coolers" don't work in real, moist air swamps, is because there is no place to transfer the heat collected by the water during evaporation. The dryer the air, the better they work.
And, yes, humans perceive a cooling effect when the water vaporizes -- up to a point. Have you ever lived in really moist climates where even sweating doesn't work?
But, I stand by my statement that, unless you can move the water vapor out of the room you have not changed the total energy content in the room.
@@lezzbmm Yes, it is a heat pump: out of the water into the "air" of the room. Once the water evaporates from the outer surface of the clay structure (pot or tubes) what control does the clay structure have over it? Please help me understand how the clay system controls the water vapor to make certain it exits an enclosed room without transferring heat to the room???
Maybe not the best as a cooler (unless you live in a very dry climate where swamp coolers are actually effective), but these would make great little indoor humidifiers for a plant room! Having a fan on them to increase the evaporative effect would also help.
❤best comment! A fan would make this 10x more effective.
Spot on about the ambient humidity. Similarly, they sell those humidifiers as air conditioners here in the humid Midwest and they don't do anything.
I'm an American, and I thought it was odd that you thought 67F was hot, because in my area we usually prefer temperatures between 70F and 72F. But I converted 23C to Fahrenheit and it apparently comes out to ~73.5F, which feels much hotter and is personally out of my personal comfort zone.
Very neat video, very fascinating. Just wanted to be an American and point out the Fahrenheit thing lol
Yeah, my ideal temperature is closer to 75F/24C.
what I wouldn't give for it to be 67°F anywhere in or around my house rn 😅
It was 106 today with over 50% humidity...
It's 1 am right now... 94 at 49%
Heat index has been 118F and 116F the last few days ... have the AC set to 77 F.
As a Texan, i was dumbfounded to hear 67F described as hot because for me that is sweater weather and temps we get in winter xD
The main thing that determines how well this technique works is humidity. If the environment is dry, these work *really* well. If the environment is humid, they will do almost nothing. Other folks mentioned a fan - that would help move that cooler air around and make it more efficient. But if the region is humid, they unfortunately won't do a lot
right! So maybe combining this with a dehumidifier. I wonder how much electricity a dehumidifier uses compared to an AC 🤔
@@PotterytothePeople less but you'd have to really check. Air conditioners *are* dehumidifiers inherently as part of their behavior, but they do a bit more. It's a trade-off.
The thing we really need to do to be sustainable is change how we build houses so we can let them not get so hot in the first place - like the Passivhaus concept
@@PotterytothePeopleAir conditioners, dehumidifiers, refrigerators, and heat pumps are all the same inside, but connected differently. An air conditioner takes heat from inside and dumps it outside, while a dehumidifier dumps the heat inside. It makes the air less humid but warmer. A heat pump water heater takes heat and humidity out of the air and puts it into hot water. If you are heating water and dehumidifying anyway, it is quite efficient.
Evaporation coolers work best where it's dry and water is scarce, and worst where it's humid and water is plentiful. An air conditioner (refrigerator,...) also cools by evaporation, but contains all the evaporated coolant. By compressing it, it causes condensation and release of heat, in a different place.
@@PotterytothePeople A dehumidifier usually just cools down a surface for water to condense on, and is seldom as efficient as an AC unit. So for the same amount of cooling an AC would be better. That said, it is possible to make desiccant based cooling systems that would provide cooling without raising humidity, the channel tech ingredients made one, but in order to dry the desiccant heat needs to be reintroduced, so you'd probably want at least part of the system outside.
@@PotterytothePeople I would think the dehumidifier would be counter productive to your goal and increase the use of energy.
I would've definitely tried this when I was in Arizona!
Here's how I would redesign it:
- Smaller tubes for more surface area. Use a small pipe to help them keep their shape.
- Arranged with a small gap between each tube into a panel (think radiator)
- Make the base hollow so that filling one tube flows into the rest of them
- Add another connecting piece across the tops for support
- Make a small hole at the top for filling the tubes. Closed with a clay lid or a leftover wine cork
- Sized to fit on a shaded window's sill for air circulation
- Place multiple panels with the tube positions staggered
@@TheresaDoneIt I live in the pnw now. It wouldn't make sense to build one here in a coastal rainforest
@@NickCombsi think you’re missing the point…
@@HouseofthePotter the point was retarded
Fins for added surface
Those seem fairly difficult to pull off with clay, but I guess if you make the pieces separately there should be a way to assemble them in a clever way? I dunno, seems pretty complicated though.
I think this is great. You've basically made a beautiful "swamp cooler". This will work well in a very dry climate. It looks very lovely too.
I used to make single tubes (with bottoms) and a hole up top for a hook as humidifiers to be hung on water or oil filled radiators (not electrical ones). Great for windowsills with plants, dry winter air etc. Never seen this idea but it will at least humidify the air. You can color the clay with maison stains and still be porous. Make them look like bamboo with a little design adjustment. Interested to hear the verdict on function!
In addition to the fan, which is going to help a lot, a grooved surface would nearly double the surface area for a lot better cooling. Probably look nifty too. I would also consider using a low fire glaze on the inside and outside of the bottom inch or so. If your evaporation keeps up with the seepage, you might get way with no drips. At worst, it will stop you losing water to wicking from the towel or surface it is sitting on. Finally, lids to keep the mosquitoes from breeding in there, avoid drowned mice, etc
Great ideas!
I wonder if adding spines to the grooves would work as well - a ceramic cactus cooler :D
Personally I think the mouse trap would be a hidden feature.
surface area is one of the major factors so grooves are a good idea. Those panels from the article she displayed weren't just ornamental they were twisty and curvy like that for increased surface area. If you could have a grooved surface in a braid patterned panel made of hollow tubes that would be ideal for surface area and filling with water.
Wouldn't requiring a fan somewhat undermine the point of passive (ie. zero power-usage) air conditioning?
One degree cooler IS actually a lot cooler. 23c to 21.5c is gonna make you feel much much cooler. I come from India, and we try keeping temperatures inside our homes around 21. I think this really works
That’s definitely true! I also suspect it worked better than I thought too because it got really hot that day but the room stayed cool! 😄 Thanks for watching :)
@@PotterytothePeople I was going to mention this - the room didn't get any hotter! Also I would place it in the hottest part of the room to maximise evaporation - by a window or in the sun, and add a fan behind it or place it next to an open window. My colleague at work used to pin a wet towel over her open window sitting in a tub of water! It worked a treat.
Also, you maybe just learned a bit more about managing the temperature in the studio by closing the door and window - it's a win all around i think!
23C is 73.4F and 21.5C is 70.7F that is almost a 3 degree F drop which makes sense since F = 1.8C +32. Quite impressive actually! This is a pretty neat passive swamp cooler.
And the hotter it gets, the better it works because it will evaporate faster.
Also, combining this with a fan behind it might be an amazing idea
No it won't feel cooler at all, as it is raising the humidity also, making you feel hotter. The increase in humidity will more than negate a 1 degree difference. Also, this will not work in areas where it is hot AND 70% or higher humidity, it'll barely function. For example here, where I live, it was just 91F and 85% humidity, this would not work.
I think if you put a fan behind them you would get or at least feel a better amount of cooling. I think they would work on the same theory as the "swamp coolers" my brother uses in CA. It uses a water cooled EVAP coil. Anyway they make for a really cool sculptural piece. 😊
I think it’s amazing and cooling the room 1,5C is much, considering that the room would only have gotten hotter because of mid-day temperatures rising. The fact that it didn’t go higher, but even lowered is just awesome, also given the fact that the structure isn’t that big. It works! I love it 😻
Why do you need to use Air conditioning in a room that is 22C??? are you insane?
@@bonaface She's making a cheese cave, obviously 😀
I feel like this would be more effective at hotter temperatures. Not much water is evaporating at 67 degrees Fahrenheit.
Look up evaporative cooler or swamp cooler. We use those in the SW USA. your idea is great. You need a fan to push the cool air around. Try putting a fan to blow across the wet tubes and crack a window to let the air circulate.
omg genius!
I agree with Carol and the fan idea, I think that will make a humongous difference! stay cool! 90F here today :(
I am also in SW US, we are the weirdos that prefer using our evaporative cooler instead of the air conditioner. We are regularly seeing daily temperatures of 110. It’s not *cold* in our house, but it’s summer, I don’t expect to be cold this time of year. (I was shocked it was 67 in your home during summer, that is the temperature of my home in winter 🤣). Anyway, for summer, we do have fans that help us sleep at night. Also, as for the idea to bury these and allow roots of plants to drink up the water-this system is called the “Olla” and developed by indigenous peoples native to dry desert climates like mine.
If you position the fan just right you’ve also made a wind instrument…
Love watching the process and living vicariously. I don’t have a kiln but I do have a number of small terracotta plant pots (and some broken ones). I wonder if stacking them together would work…
You should try putting them in front of a fan or an open window, the air movement will help the water evaporate faster and mix the cold air around the clay with the air in the rest of the room
Since you live in Germany, I suggest you talk to your neighbors about lüften. My family tends to open up windows at night, close them up in the morning and then bring the rollos down wherever the sun is shining from, so the heat doesn’t come in as quickly. Then as soon as it gets hotter indoors we make wind by tying all the doors up and opening specific windows. If you are using humidity cooling (which you are) you need to cycle the air more, as it will make it stuffy.
Thanks for conducting this experiment.
Even if your experiment didn’t work out how you had hoped, it was fun to watch and I appreciate your continuous ingenuity. It always inspires me throw caution to the wind and experiment with the clay to develop better ideas & ways to work when it comes to our art pieces. Bravo! 👏🏻 👏🏻👏🏻
Thank you!! Yes the experimenting is absolutely the most fun part 😄😄
I loved this video and the thoughts and motivations behind it so much! I'm an evaporative cooling hobbyist and I'm sure others have said how you're actually so close to making this a practical thing to use to cool your home especially in Europe! All you need is a fan or some air flow with an exhaust to let some humidity and air push out! Passively moving that air is difficult though so I understand your apprehensive to add an electric fan. Maybe run it on solar from the roof with a small 100w panel? Very excited to check out more of your channel
More artists and craftspeople need to explore alternatives like this.
This was really interesting, but it made me laugh when mentioned the temperature. I’m a southern Californian and it’s typically around 40C in the summer time, and 20C is cool for us. We would never use the AC in those temperatures.
Same here, 20c is pretty much the dream temperature wherever you live in the USA, haha
The concept is great…placement and airflow could make a big difference. I look at your project as a jumping off point for some fun functional art. Thanks so much! 😊😊😊
Climatisation
I'm from Florida and 20C is still much too hot for me. That's why I'm _from_ Florida, not _in_ Florida.
you use Celsius in California? what happened to Fahrenheit?
I just started watching the video but I can tell you Yes, this will work. This also works with bamboo. You need to drill holes in the top 3-4 inches (some have made designs with drilling the holes.) It works better if you have a small fan placed tilted up with the tubes circling it set on the lowest setting. Green bamboo is best. We did this as a science project.
I love seeing the creative process with artists in different mediums. The same way you look at a bent tube and go "ah, looks like coral" same exact thing with music and 2D art haha.
I might try it near some airflow. I'm so glad I found your channel! Thanks!
Run a fan onto your cooling tubes. This will increase the rate of evaporation and spread the resulting cool air around the room. This is basically a deconstructed swamp cooler :)
I think you need to test the effectiveness of this system in a room temperature hotter than 67 which is pretty cool already.
My mother was a potter. Do what she did: she stuffed pipes and pipe-like stems on her pots - with cardboard tubes from wrapping paper. In a more modern version, you could try pool noodles, at least until the clay reaches leather stage.The ancient Persians (who invented this technique originally) placed the pots at the base of ventilation wells - wind catchers. The wind catchers (still in use today) created a steady breeze. You would have MUCH better success by simply putting on a fan. and circulating the cool air around the room! Love this highly inventive and interesting content.
Looks good for outdoor areas
Interesting info to add to the convetsation, in South America, torids or terra cotta donuts would be filled with water and placed in an open window as an AC. If you put a fan next to them or had them in an open window, it should work. Great video as always. Love how you think out of the box.
that sounds like a very pretty design too! thanks for sharing!
Can you post a rough visualisation pic of what you want to suggest if you dont mind
Lovely work! don't give up on it. When I was growing up in Sydney, we would put small towers of terracotta pots filled with water on the verandah of the house and it really did drop the temperature. I think the design of the one that you show at the start has a few benefits that you could play with: being external to the house, being a whole wall, and having small small tubes that create a much bigger surface area by twisting kind of like our brain does. In theory screens made like this that could fit into your window or door should work - ideally not in direct sun.
It works in a static situation until the cool water is equal to the outside of the container temperature. The water becomes a heat sink for a bit of time. Keep air moving across the tubes and the room will cool but get more humid until things equalize. The swamp coolers recirculate water and fresh cool water is mixed in as the water evaporates away which takes heat away. Static tubes only make for a temporary heat sink.
Great job on the video. They're beautiful!
I can't remember exactly but I saw this project where they were using bamboo to do this in a huge scale and it works
As someone who has always been into science but used to be very into creating art, especially with clay, I am so very glad I stumbled upon this video. I have my grandma's kiln in storage and look forward to finding a place I can put it to use so I can explore concepts like this. And, say, terracotta cooling of larger volumes water.
I think it worked great. You should have compared the room temperature with the temp outside. I guess after a couple of hours the temperature must have raised outside but in the room it was kept 21.5 which is very pleasant. Also I think this works better with a roof fan or a continuos current flowing in the room (at least two openings) and with low light. Great job, beautifully made.
Watching your videos are what got me interested in taking up pottery! Thank you for your videos and echoing what others have said I would love to see your glazing process
It's cool that the process has built in down time so doing the maintenance stuff doesn't feel like wasting time.
I loved it! So cool to see your channel growing and your videos improving. ❤ Nice to try and change the world, even just by bringing the conversation and well intentioned ideas.
thank you! 🥰🥰
Mia I’m confused… I live in SE United States where the temp today is 93F (34C) and 70’s F is actually very comfortable! Even with high humidity! Did you get the temp numbers right?
yes lol you are right to be confused! i started the project during the heat wave but it took 2 weeks to finish so it was much more temperate by the time i ran the experiment 😂
This is one of the best RUclips videos I have ever watched! I teach ceramics and I will be sharing this with my students and how creative we can be with this ancient building material. Cheers!
I am so glad I got ac a couple years ago. It’s only the one room but it really helps me to sleep better when it’s crazy hot
I'd be interested in seeing another update when the weather is warmer. I wouldn't run the A/C at 67F so testing it at that point doesn't mean anything to me. Plus, it would probably do a lot better in higher temperatures.
You might be able to slide those clay tubes onto some cardboard tubes to dry them, or maybe try hanging them to dry to prevent wrinkles from forming on the bottoms.
Great idea! I only realized it's a problem after I started 😂 I guess that's why prototyping is so important!
I grew in northern Haiti, a small island in the caribbean and I remember we didnt have electricity 24/7 and my grand parents would literally get a big clay jar and fill it with water and just place in a corner. Water would be cold when you drink it. So I think this concept could definitely work. Just get big enough jars or tubes made of clay in place them in the 4 corners of the room and you have fresh water as well as cooling system in the room :-)
It's also known as a "swamp cooler" because it increases the humidity and absolutely doesn't work in hot and humid weather.
We use a similar concept to offer our rats some cooler spaces in their cage. They don't have tubes filled with water, that screams for a disaster to happen, but we've got a few clay pots in the cage that we wet regularly to create cooler areas so they chance choose to move wherever the temperature feels right for them. Works great for other smaller animals like mice and hamsters too, though my mice never likes the cooled pots and always stayed away from them lmao
If you have the space for it, consider adding a granite tile to their cage. Typically marketed to Chinchilla owners as a "cooling stone," though you can buy them cheaper in a hardware store.
@@xxgn thanks for reminding me, been wanting to do that for ages but keep forgetting to get one when I'm at the hardware store ^^'
Also, if you don’t have an extractor, these tubes could be made with slabs and stuffed with lightly balled up newspapers or something similar, to help them hold their shape while drying . I’m a retired teacher - what a fantastic science experiment this could be! And artful too - let kids carve in designs…
I love the marriage of science and design in this project!! While not good for the environment, a cut pool noodle could be used to keep the tubes upright as they firm up
Hi, as an engineer I think I may add some upgrades.
Put enamel on the outside of the bottom of the tubes and enameled pottery dish - lower leakage a bit.
Add fan - enhance evaporation and thus cooling effect.
Stagger the tubes - better airflow and again it increases the cooling effect.
Use thinner walls - increases leakage but may enhance cooling considerably.
Use some kind of bio-neutral dessicant somewhere near (maybe opposite side of the room) - lowers the humidity of the air and thus helps with evaporation (see above).
Use more tubes with smaller diameter - increases area for square meter and also it means higher eveporation again.
Generally this kind of cooling works the best at higher temperatures of the air so this might be more valid option the higher the initial temperature is. Also there is much more possible enhancements, but without proper calculations and drawings it's hard to explain in a plain text.
Hope this helps with improvements and if you ever try it, I'd be glad to see the results.
Great work, I like that you kept the organic design it just came out as. Since this relies on evaporative cooling a fan could help, but maybe a completely passive system could be placing this higher from the floor (hot air goes up, cools down and descends to the floor). I'm thinking of hanging sponge tube corals ;)
Very interesting video, thank you for sharing! I think that your experiment worked better than you think it did though; you noted that the room started at 23 degrees C and that that was 67 degrees F. In actuality, 23 C is closer to 73 F which means that your experiment dropped the temp by 3 or 4 degrees, not 1! And every little bit helps!
Yeah, I think she misread the thermometer when looking at F degrees, it made no sense that the C degrees had a bigger drop than the F degrees. So it worked better than she thought. :)
That kiln uses the same amount of energy as 30 ac units. Don't lecture ppl about shit u don't understand
Shhhhhh logic and facts aren’t allowed. Just agree with the current agenda lmao
LMAO! you know damn well the algo is gonna make this shit widely viewed because of the BS she said about AC and global whinning. idek why i or how i got here
Channels like thesemake me feel like going back to my ancient pottery roots.
During my childhood, our town had this massive greenhouse that my family and I would often visit. One of the unique features was a wall on the end that resembled a honeycomb. Water flowed over it, creating a cooling effect throughout the space.
Thank you youtube for recommending this Queen 🙌
I love your energy and editing and everything else 😭😭❤❤
New sub!! Can't wait to binge all your videos!!
I'm really sorry if this is a weird question, but where did you get your overalls? I've been looking for something like them!
A few things that might help. 1. Increasing surface area by introducing ripples into the clay. Squish it a bit one way and squish it again another way slightly above it until you get something undulating? 2. Setting it near your window, with the top covered with a cloth or something. The wicked water can get the extra boost to evaporate using the sunlight. The cloth is to keep sunlight away from the internal water to prevent algae growth. 3. Instead of adjacent flowering pattern, have a linear wall with some gap between each tower. Against a window, it would provide more shade against the warm sun. If you want more sun, just shift the towers farther apart. More shade, shift them closer together.
A really cool video. It was entertaining to see you explore the idea.
Thanks!
This was incredibly interesting 😮😊
I think this will be more effective with open rooms, as the idea would be for the air to take the vapor away and thus cooling it down. Another thing to note is the region you're in. This will certainly be more effective on less humid regions, as it requires the water to evaporate to cool down. You can also combine this with a fan in order to make it dry up faster while also spreading the 'cold' out of those tubes
Been loving your videos! Can you share what camera and video editor that you use?! That would be so helpful, thanks!!
If it’s about surface area, would adding grooves/textures to the tubes help out?
Great work!!! any emissions out of the kiln?
Satisfying
Great video
That's a really interesting approach. It will cool the water that is remaining inside the tubes . You can use the cold water. If you can get the moisture blown outside your house it will take the heat away and cool your space.
Ok, those of you in dry environments can use these water coolers. Where I’m at, the humidity starts every morning at 100%. Then gets down between 50%-70% during the hottest part of the day. Like right now it’s 100° and 58% humidity. Water coolers in a humid environment only raise the heat index.
mold loves this technique, also really works when it's dry with a breeze
First time watching any of your videos. That was really interesting. You seem cool and knowledgeable.
The moisture, that these items provided, is why the room felt cooler when you walked in vs the humid room you just left.
Coming from Florian Gadsby and seeing this as the first of your videos, I'm hooked. Would love to see a second go at it, maybe using a two part mold or a hollow cast part design! Cheers :)
Maybe 2 hours are not enough to test them… I’d test them later again.
I love your videos and ideas. Your way is so cool! 😊
im just imagining some kind of ancient style home built around a massive one of these in the center built in a circular shape so that every room touches it, and the top could be exposed to the roof so that it collects rainwater. now im thinking about how the future of architecture could be shaped in sustainable ways like that to help us combat global warming. amazing video! :D
I think the cooler will function well to maintain the coolness of the night. That it cooled its surroundings at all when started midday is amazing!
what if you keep the water mooving? like monish siripurapus wall systems... i wanna try this tho
Hi thank you for your interedting video. I am quite intrigued by your extrusion apparatus.
What is the name of this extrusion device and how it is made?
Thank you and have a pleasant day
They look really cool. We bought some evaporative cooling fans for our deck, they work very well. But that's also because they get loaded with ice and have a fan lol. Those would probably work around plants to increase humidity.
Would more, narrower tubes taking up the same space work better or worse?
would it be possible to make only a part of the lower section water proof?
In New Mexico's dry heat we use swamp coolers which are basically the same concept: a diy version is to just hang a white towel across a sun facing window and feed the cloth a small waterline to keep it quite damp, as the sunlight heats the cloth the water is evaporated to the outside and the temp inside the room drops. If you have a rafter window its ideal, the colder air is displaced by rising heat creating natural air circulation.
This is an awesome video! I have a question: is your home insulated? If not, I wonder if the cooling would be even greater if it was.
great video
Cool video. Interesting idea. I wonder it it would work as a hollow window frame. With maybe elaborate designs or even abstract designs. The air would cool as it would pass through the window or could it be made into a makeshift air conditioner with a fan.
I think the reason the design you originally saw worked is because it's a full wall of terra-cotta with a high amount of surface area due to the patterning. In the day when humidity is high, it's porous enough to absorb the high humidity of the hot day (hotter air can hold more moisture) when it's dry, and when the day cools down at night it can leak the excess water. Likewise on a very dry day, any latent moisture in the wall can evaporate to give the impression of coolness similar to a swamp cooler (an evaporative AC, basically) by lightly increasing the moisture. If you need to add more moisture, you can lay out bowls of water, or if this is fashioned just so, fill a reservoir with water so that it can leech into the wall and evaporate more throughout the day. Your idea is combining the reservoir with the terra-cotta, but yes, you need a lot more to have a significant effect. A dozen small columns isn't enough. You would need a hundred, if not more. In a small dry room with a lot of heat these would lower the temperature quite a bit until the ambient air reached its saturation point. By then though, the humidity levels might make the room feel stifling.
The reason we moved away from evaporative cooling like this to condenser heat exchangers is because it ensures that the heat is expelled outside of the space you're in. There are passive ways to use that heat exchange method, but it's really expensive and unmanageably large and bulky to do on a house scale. Cooling a CPU, for example, is possible with a radiator the size of the computer case it's mounted to. That's enough to keep the CPU well below it's 100C limit, but ramping that heat spreader to room scale the cooling effect would be no where near as effective and the radiator would be the size of the side of your house. You're better off going with better insulation to reject heat transfer altogether.
Why cant these terra cotta evaporators be out side and have a heat sink to syphon the heat energy from inside? That something thats been bothering me about these like leave the evaporated water with all the heat outside by using the heat inside to help with the change of state, or using water under a vacuum in a closed loop to boil at like 20c(or what ever temperature is achievable in the condenser) and let it condense out side in a terra cotta cooler. It seems like it would self cycle the water under a vacuum too. Basically what we do with refrigerant just with out adding a bunch of pressure to make the heat shedding easier. Is this complete bunk? Im sure im missing something and it can't work that way I get it I'm an auto mechanic I know Im coming from limited knowledge. Ive wanted to ask someone that has like physics degree if its a really dumb idea.
@@Jesayouthis is actually basically what a AC is and does. Water is a refrigerant after all but because of waters higher boiling point you HAVE(unless you want the energy/heat it takes to boil water constantly without the assistance of vacuum to make it less energy intensive) to use a vacuum pump just the same as the refrigerants we use today and it would cost a ton of energy because the vacuum it takes with water is pretty high(not very but a lot compared to modern refrigerants which only need a ten or twenty psi less than the atmosphere pressure).
The reason why AC is mostly linked with climate problems is not usually to do with the methods itself it's with the shitty disposal and use of bad refrigerants which we are still dealing with the consequences of today. Not to mention that the energy that they consume is quite a bit, now if we instead of having ACs being constantly at war with the outside temperature(why it actually takes so much energy, if you have ever had a chest freezer it works the exact same but one obviously is way less energy for something that can get sub 0 temperatures it is all due to the escape of the cold into outside elements and it isn't just due to size it is actively fighting against the outside elements because our houses are not fully insulated). This is why a better insulated house will hold in cold much better and why central AC is way better than a Window AC unit.
Sorry for the rant it was something I looked into in a hyperfixation on refrigerators and why chest freezers are less energy than upright fridges that are in style. ADHD engineering at it's finest lol.
@@pf6137 I was definitely not thinking of course the expanding of the water boiling would increase pressure that would require more vacuum to keep the boiling point low I was a little intoxicated when I came up with the idea
Could this design be used for a mini pipeorgan?
do you think this could be more efficient if the tubes were larger and higher ?
Interesting implementation. You look a lot like Simone Giertz and styropyro had a kid. A few points I can think of.
1. Air circulation will help a lot.
2. The lower your ambient humidity, the higher the cooling effect.
3. Look into mitticool. It's an Indian startup which makes refrigerators by clay. Maybe a future project?
4. The maximum cooling possible with such a method can be calculated using a psychrometric chart.
Keep up the good work!
If you use a fan to push air around the tubes it will encourage evaporation and therefore additional cooling.
A room full of these would be so beautiful
How does this work explained in physics terms. I am wondering because the evaporating water would just displace the heat not make it disappear effectively making the water cooler but the surrounding air hotter.
Even if it doesn’t work they are so cute and would make great pots for vine plants
I am wondering about mold issues on these pieces? Did you experience any mold?
Will definitely play with this theme and explore it. I am already using ollyas in my yard to conserve water and energy.
Nice. I feel like you'd need a shit ton more of the tubes for it to have a significant effect on a room
What is the wall tool you use so neat
Loved the facts part about A/C and interesting video in general. I love the architecture that utilizes the natural phenomenons and physics. But a good isolation in buildings is ultimately the way to go!
I think it may have worked, if nothing in the same room. Would the temperature of raised with no clay water tubes?
seems like a really neat idea! I live in the southeast US where its really humid already and idk how effective evaporation based cooling would be out here (current humidity is at about 60%), but in dry climates this seems like it might work!
