Love your videos, great sense of humor! Very educational. In Texas before electricity people built their houses with very steep high roofs with a vent at the apex of the roof, so when the lower windows were opened it caused an updraft like a chimney, cool air in at bottom, hot air out at the top.
Another great video, thank Kayleigh. As for pubs in England, yes there are a lot. Where I grew up there were 21 pubs on a one mile stretch of road, it ensured that you had plenty of choice. There was a standing challenge to walk the length of the road having a pint at each pub! - never really tried it myself, but knew several who did try and a few who succeeded.
@@HistoryWithKayleigh Just one of those things that people do in their teens and early twenties. I was always a light weight drink wise, so never tried it. My one brother tried the Gornal Mile as we called it several times, but ended up having to settle for the Gornal Half Mile - that's the same one mile of road but just a half-pint at each pub, so still ten and a half pints!
Those of us who grew up with evaporative coolers (swamp coolers) know exactly what these ancient folks took advantage of. Any appreciable drop in temperature would be considered a real improvement. These ancient people took advantage of physics even if they did not fully understand it. Shade, moisture, and moving air can give cooling. Very nice video and explanation. Don't ever get discouraged by nay-sayers. You are providing really good information.
Swamp coolers. Ack! LOL I have never understood those, although I have had them off and on over the years. All I ever felt was the high humidity they sent into the house. That was in the Sacramento valley of California, which is pretty humid, in spite of being on the edge of the desert. Back then, (70's) it was mostly rice farms, which use flooded fields to grow rice. That might have contributed, idk. Personally, I think wind catchers would have worked better! A breeze would have been nicer than what the swamp cooler spit out.✌😸
I live in Melbourne, Australia where summer temperatures will often get to 40° C (104° F). We usually have low relative humidity on those days and can get the inside temperature to a comfortable 24° to 28° using only evaporative cooling. We do get the odd day where it is both hot and humid (like in the tropics). On theses days, the evaporative cooler doesn't do much (in fact, it seems to make it worse). Fortunately, here in Melbourne, they are few are far between. We all love the open, airy feeling the evaporative cooler gives our house in the hot weather and do not feel the need for any other form of cooling.
Ignore the negative comments. I used to work at museums, people want to comment negatively, especially other people from museums, but it is just ego, they want to show how they are clever. Now that you are 30, understand that it is their insecurity and you don't have to reply to each silly thought people utter or type. Just do your thing the channel is great.
I grew up in Laredo, Texas which is a desert climate that will have 100°F/37°C. It was similar enough to Israel that an Israeli university had a cooperative farm project there at a local university. One of the technologies they experimented with were these odd little buildings that had sort of chimminies in the roof and could be kept quite cool passively just using shape, materials and paint color. It was amazing to walk in from a scorching day into the shade in one of these buildings that were at least 20° cooler. It is my understanding that they were using this same ancient technology as inspiration.
Thank you for sharing the additional info. What I found most interesting was the way they channeled airflow. Yes, it is a swamp cooler. It is a swamp cooler without power.
Awesome presentation I'm taking notes. Appreciate your content and love the video about the Deserts ice domes. Yorkshire, England in the house....Wishing you all the best in the UK!
They need these wind catchers on the Houses of Parliament - lots of hot air there! In Northern Australia, I set the thermostat to 30*C, to cool the house down.
You're doing grate. the majority of people who don't understand are still learning what you have learned in your research. Their comments are just a reflection of how much they don't know. It's good to address the misconceptions that may build up from not knowing about historic life. I think its a compliment to have questions to answer. Congrats on England, WOO HOO!!
If you live in a desert, humidity is not much of a problem. So people whining, "That's not A/C" says a lot more about them than it does about this cool invention. Having stayed in a small hotel in Dubai with a wind catcher, I can attest that it made the room much cooler than the outside air. The fact that it is also passive technology makes it that much more impressive.
Hi Kayleigh I grew up with evaporative cooling ( Swamp cooler ) here in the Central Valley of California. We are fortunate, in that our summer humidity is very low, except in late July of early August when we have what is jokingly called our " Monsoon Season ". These are a few days when the moist air moves up from the Caribbean ocean, and causes a massive increase in humidity. So for a few days our evaporative cooling does not work, and we simply resort for the cooing effect of moving air. Not verify pleasant, but barrable for a few days a year. Evaporative cooling is most effective, below 22% relative humidity ( RH ) which is this method of cooling's design humidity for engineering calculations. While our humidity had steadily risen over the decades, due to massive planting, and irrigation, this cooling system is very effective, both comfort wise, and energy efficiency wise. ( I remember many summers ago, as a child 65 years ago, that the RH was about 5 to 7 % percent ) At mid afternoon we would sometimes have to stop the cooler as it had gotten too cool inside our home, this with an OAT, ( outside air temperature ) of 120 degrees F. ( 49 degrees C ) A properly sized evaporative cooling system will reduce the internal air temperature as much as 40 degrees F @ 22% RH. ( 17.5 Degrees C ) All this cooling effect with the use of a 560 Watts per hour of electricity, ( 3/4 HP electric motor, vs a 3 ton mechanical system using 3.375 KW/HR about 4.5 HP. Since I hold degrees in HVAC and taught the subject, as well as a MS in mechanical engineering, I have run the numbers many times, and written a textbook on the use of the Psychometric chart. Any doubters really need to understand the Pyrometric chart, and how to use it. I know it is a bit hard to understand at first, but as the most difficult class to teach in HVAC, I always had great success, and never had a student fail my class in the subject. What many folks do not understand, is that evaporative cooling requires that 100% of the air brought in must exit the structure, which is exactly the opposite of what is required for mechanical air conditioning. While it is simple enough to just leave the windows open to achieve this exodus or incoming air. I design evaporative air system to exit the cooled space through " Up Ducts ") that lead into the attic space, and out through the peak vents in the roof, thus cooling a very hot attic space. Thus further enhancing the cooling of the structure. The definitioning of Air Conditioning is misunderstood by most folks. Most people have comfort heating and cooling, but not true Air Conditioning !!! True air conditioning requires that the air in the conditioned space be : 1. Circulated 2. Heated 3. Cooled 4. Filtered 5. Humidified 6. Dehumidified These conditions are rarely if ever meet in the usual residential or business spaces. True Air conditioning is only used in climate controlled spaces like metrology labs and places that require exacting control for industrial processes, as it is very expensive to install , maintain and power. I have studied ancient civilizations, and am always fascinated by the expertise with which the are engineered. While the science of engineering these areas was not understood at the time in history, the ancients obliviously understood the working principals of what the built and were very much in tune with nature, as they were excellent observers of nature. I couldn't justify being an Archeologist, Egyptologist or Paleologist. While extremely interesting, they could never be justified financially. I come from the real world of farmers and agriculture, and the necessity of keeping things repaired and productive on a timely basis. Thank you so much for show casing the ancient worlds science and technology to a whole new generation of folks. These younger people will take this knowledge and add to it, and make ever many more creative and useful things. Tim
Loved the video! Very insightful. I grew up with big fans built into the ceiling of the hallway, when switched on and the windows were opened. They blew the hot air into the attic which had vents on both ends. It was amazing how cool the house was.
I think a lot of folk, don't actually grasp the definition of the term: Air Conditioning = to equip (something, such as a building or vehicle) with an apparatus for washing air and controlling its humidity and temperature(from Meriam-Webster dictionary). Which is EXACTLY what these wind catchers do. People need to stop fixating on air conditioning being a device that can exactly control temperature, or use electricity and/or compressed gas. I find it fascinating that people visiting your channel could be closed minded & view the world through tunnel vision. Keep up the great work Kayleigh :)
Hi K, you won't need air conditioning in England (trust me, I live here). You will need: #1 An umbrella #2 A warm waterproof coat #3 A pair of wellies (yes, i did say wellies 😉). As it is generally cold and raining..or both. We do get the occasional warm summer, but you will survive I am sure. Interesting vid K...peace to ya.
We in the states use window screens to help with the bug thing. I know in England they don't really use them. Idk about where u r though. So if u r trying to reduce the bug issue use window screens. Also for ant problems, sprinkle egg shells around the home...it will help immensely. And then for other bugs, plant lavender around the home, inside (if possible) and outside. And then for mosquitoes, burn citronella candles. Hope this helps. But either way, everybody has some bugs wander in....cuz unless u live in a bubble, it is just a part of living on the earth. :) 😀
Two things: one, for humid climates you need the wind to be channeled underground to pick up on the cooling effect of the ground; two, for meshes to be used and not have them constrict the flow below desired rates you need to increase the intake rates to compensate and increase the area covered by the mesh.
@@HistoryWithKayleigh You're very welcome and thank you as well haha. I hope yours has been as amazing as you are. Truly one of my favorite people on TH-cam.
Personally, I find it fascinating, how advanced ancient cultures were. They prove that limited technology does not mean limited intelligence. And, without their ingenuity to build upon, we may not have a lot of the things that we do, today.
@@HistoryWithKayleigh you are a wecome antidote after watching some nonsense on the "History" channel claiming that Leonardo's genius can be explained.....he was abducted by aliens for two years who gave him the knowledge, Oh of course why didn't I think of that?
we in Ontario say ''it is not the heat -it is the humidity'' -we have a lot of immigrant folks from Africa and the Caribbean who cannot believe how un comfortable it is here in summer.
The fact that it was created 5000 years ago is an amazing feet in and of itself! The plus side of not having a thermostat is you don't have to hear your dad complaining that somebody touched the thermostat.
Your enthusiasm and insight makes me eager for each of your video releases. Of course the ancients did need to use ingenuity to make their lives as comfortable as they could. Necessity, as they say, is the mother of invention.
G'day Kayleigh, you are absolutely right this is the first air conditioning, l am a qualified Plumber, and in the dry climate of Australia we use water and wind to cool our homes in the form of evoprotive units on our roofs and ducted to all rooms, water is added to the air for cooling, air is drawn through wet pads on 4sides of the unit and a fan blow cooled air into the ducts, this will reduce the temperature inside between 10c to 14c, so not a lot of difference, the other type is refrigerated which is totally different, hope this helps, cheers Neil 🤠.
Something to think about.. what other technologies would people be dismissing as not anything interesting or new if the library at Alexandria had not been burned to the ground? Actually, if I can make a request… can you make a video about the library at Alexandria?
Excelente el video, muy bien explicado, felicitaciones, creo que en la India había un sistema parecido, pero no estoy seguro, tal vez usted pueda investigarlo.
3:45 "I'm moving to England in the new year. And England is known for not having air conditioning so I'm f**ked." - History with Kayleigh. I thought this was funny! But also so true....lmao 😂🤣
Always great to see another video from you. If I may, I know it's an American holiday, extend a Happy Thanksgiving to you and everyone here. Anytime one can gather over food and drink with family and friends is a good one.
Arguably, changing the temperature inside of a building is Conditioning the Air. Air conditioning, often abbreviated as A/C or AC, is the process of removing heat and controlling the humidity of air in an enclosed space to achieve a more comfortable interior environment by use of powered "air conditioners" or a variety of other methods, including passive cooling and ventilative cooling. …. Did someone think that Ancient Rome had window units?
Some people live in cities on valley floors and notice it's hot there. They travel to surrounding hills and notice that the air is cooler there while it's hot down below. People build towers and notice the same thing at the top of the tower. So, they rig a system to bring that cool air down below. Life is good. Then, they notice that air that flows over water becomes cooler. So, they do that. Life is better. They lived happily ever after. 😀
I think these passive, no electricity systems are fascinating and worth looking into--especially in applying new materials and technology to help improve them. For example, one could use vacuum insulation panels, combined with ultra white paints, and mirrored aluminium to direct IR energy up into space, and have a constant "icebox" on top of their roof. And which could easily be converted into a heater in the cold months with a glass top.
When I taught English in Thailand, the temperature was usually 90+ degrees Fahrenheit, in the classroom, with no air conditioning. And I needed to wear a collared shirt with tie and pants. Imagine being on your feet for hours at a time in that kind of heat, shouting over the din of 50 Thai kids until your voice goes hoarse. Yep, it was rough at times.
Don’t kill the spiders. They keep it bug free. Around the equator small lizards are accepted for bug control. Keeping that in mind. Anything bigger than a nail? Usher it out doors. Everyone grow up!
@@pattheplanter licking the eyes thing really makes me laugh! It never gets boring! Having a bad day? Eye lick! Dog lost a foot then got lost? Eye lick! Lol
My grandparents when living near Brisbane had a 'pet' frilled lizard. He (they think it was a he) controlled the bugs. Apparently he just kind of moved in. He was doing no harm and controlling the bugs so they let him stay. This is obviously not going to work in the UK.
I have a couple of gecko's that do the same by me. They eat the annoying insects, and i let them be with no problem. Plus they tend only to come out at night, and make only a tiny bit of noise.
To those who brought up swamp coolers, technically a wind catcher is not a swamp cooler. They could be used together but they are two separate things. A swamp cooler involves a wet surface to cool the air as the air blows over or through it. It's a form of evaporative cooling.
Bugs? Try spraying very dilute eucalyptus, and peppermint oil...a tiny bit in a swamp cooler gets rid of lots of bugs too...ok...OK swamp cooler and wind catcher, same principals...lol.
These Wind Catchers would work well here in Los Angeles and a lot of California. We do get some humidity, but it's rarely high & we pride ourselves on the dry heat here in Los Angeles and most of Southern California....
Hey Kayleigh, I learn a quick method to convert Celsius to Fahrenheit, I was always confused too. Double the number and add 30. It’s not exact but with in a degree usually. So 30C = 60+30 = 90F. 🙃
Another way (that IS exact) to figure cetain C and F temperatures is to use the "rule of 14." 15, 20, 25. 30, 35 degrees C equal 59, 68, 77, 86, 95 degrees F. Notice that the Fahrenheit digits all add to 14 and are symetrical around 77. If you can remember that 25C = 77F, then you know many of the temperatures within the range of human comfort. Because the digits of 14 add up to 5, there is a similar "rule of 5" that works all the way from 5 F to well above the boiling point of water. The decimal F temps between the whole number temps aren't too hard to figure when you have such a solid framework. 26 C = 77 +1.8 = 78.8 F Celsius/Fahrenheit 4 4 4 4 4 5 5. 5. 5 5 5 14 14. 14. 14. 14. 5 5. 5. 5. 5. 14 14 14 14 14 14 5 5 F -40 -31 -22 -13 -4 5 14 23 32. 41. 50. 59. 68. 77. 86. 95. 104. 113. 122. 131. 140. 149. 158. 167. 176. 185. 194 203. 212 C -40 -35 -30 -25 -20 -15 -10 -5 0 5. 10. 15. 20. 25. 30. 35. 40. 45. 50. 55. 60. 65. 70. 75. 80. 85. 90. 95. 100
This was great technology, and still is, there are numerous places that have incorporated similar system into modern buildings. It is a a means to cool large areas without the need for any external power.
India has a temple that shows how people operate it with ropes and pulleys manually. The columns actually have obsidian cast pulleys on the columns. But the carvings show show people with approx 10” diameter ropes. They put the operating instructions in carvings on the temple. Lol now that’s how they operated over there. Check out Praveen mohan arc reactor temple. Don’t get wrapped up in his interpretation. It’s manually operated when it’s components are missing.
@@MrFlatage the temperatures would fluctuate with that dome, I’m assuming they took into account solar load accumulated then transferred inward at night when it’s cooler.
Hi Kayleigh the easiest way to work out Fahrenheit is say it’s 20 degrees then double it gives you 40 then add 30 then subtract 3 gives you 57 degrees Fahrenheit
Anyone who has a problem with little fruit flies just take a clear jar and add about a Quarter of an inch of apples cider vinegar with one drop of dish soap cover with Clear cling wrap then poke a few holes in the top with a knife. They will check in and won't check out
@ 3.50, england has lots of air conditioning. it's in most offices, people like me who work on the factory floor just have to sweat! as for the wind catcher, it may not be "air con" as we know it now, but it makes life better for the residents, and it works WITH nature. we have forgotten far to much ancient / passive technology. even the humble veranda has largely gone now.
Hi Kayleigh, may I suggest you to make a documentary on 1. Bridge between India & Sri Lanka 2. Pangea continent 3. Gengiz Khan 4. Qutb Minar tower in Delhi. How it's never rusted Love your videos. Very well done. Why don't you move to Dubai
Cooling in ALL climates seems to have gained headway now that researchers developed radiative coatings that convert heat to the same IR wavelength that the humid atmosphere is transparent to. This actually allows the roof to eventually drop BELOW ambient. I presume most homes heat loads exceed this ability but it certainly helps. Every bit lost at night takes a bit longer for the sun to heat back up in the morning. Most people still don't actually understand how evaporative cooling works. The water evaporated does not dictate how cool the air feels but the more room the air still has for MORE water AFTER absorbing the intial water dictates how dry and cool the air feels. People in dry West Texas often complain of waking up in the middle of the night shivering from their powered evaporators.
i somehow doubled the earlier comment, so i edited one to start over. hey, Kayleigh! can't wait for the museum video! it'll be great, i'm sure. it blows my mind that you got so many comments deriding the astonishment of ancient cooling🤯 as you said, i don't think those people realise the extent of brain storming it took to come up with this idea. so many take the modern conveniences for granted. the tv was a good example. other than natural structures or critter behavior, the ancients had nothing to go by. creating wind catcher cooling systems was as ingenious as anything today, for their time and technology. we need to give them their due. anyhoo, m'lady! i'm so glad to see your lovely face👸 and to see the results of your lovely brain💎every time i watch. come on, people! how can you not subscribe?
I have mosquitos and spiders in house, besides living on 8th floor and in quite cold and dry area. Apparently they are simply better from us and we need to adapt.
How to keep bugs out of the house here in Arizona we or some of us use bug zappers at the entrance of the house i got one on the porch and one un the foyer
Thanks for the video❤️👋👍 I like the educational value and of course your presentation which is modern and refreshing. As for the negative comments from stupid trolls, just smile and start laughing then ignore their meanness!
Kayleigh, you will find the negative opinions of those who watch your informative and interesting videos are Philistines. The cooling technique used here is the best the ancients could do with technology available to them. They used the climate to their advantage. Most of the people who would correct you couldn't get by without their modern convivences. Negative critics are like dandruff, just brush them off and keep on doing this type of thought provoking stuff. :)
One other thing of note is that heat is more tolerable in arid regions, than in humid climates. I rember living in Spain in the city of Salamanca. It was a dry climate. When I returned to the US, to New England, I found the heat intolerable as it was humid heat. I would also go into the big cathedral to enjoy the coolness from the heavy stone walks, listening to the organist practice their music. I do agree this thing you describe is amazing. Kenots are an amazing nonelectric invention for climate control in that region. It could definitely be applied to modern building in some areas of our country, reducing our use of electricity and cost. Of course it would not be so useful in hunid regions. Humid areas had their solutions. Some of the comments you tell of are quite disturbing, as they obviously have very little concept of how pre electric people solved problems. Also, many people of today gave not lived under pre or non electric conditions, so they are perplexed by non powered solutions. They just don't believe they work, when they actually do. I have been fortunate enough to have lived in the out islands of the Bahamas before there was electricity there. The if island and cities, such as Nassau did, but the little island in many cases did not.
As a rough guide to convert from Centigrade to Fahrenheit you double the number and add 30. So 20 C° becomes 70 F° Note however this only works over a relatively narrow range. There is a very interesting book on Iranian desert architecture titled. 'Living With The Desert: Working Buildings On The Iranian Plateau' By Elisabeth Beazley & Michael Haverson. It covers the Wind Catchers , Qanats/Kãrīz and Iranian Windmills (The late Michael Haverson who was a great friend wrote the chapter on the Iranian horizontal windmills. Which are quite unlike European vertical windmills!).
At 9:20 you ask if Any one knows how to keep mosquitos, spiders, & fruit flies out of the house. I have found a partial cure for fruit flies that may interest you. It uses no electricity or other power source. We bring fruit (like bananas, peaches, tomatoes, etc) into the kitchen to ripen and had horrible troubles with the fruit flies they attracted. We found that we could almost completely eliminate the flies with a simple trap. We use a wide-mouth plastic container with its large flat lid, like cottage cheese and some other refrigerated foods are sold in, and put waste pieces of fruit in the bottom. Leave the lid slightly ajar so that the fruit flies can enter. In the morning, and several times during the day, clomp the lid closed and carry the container outside to open it and let the collected flies fly away. Sometimes, you will have caught 50 or more. Every day or so, discard outdoors the fruit being used for bait before new flies are bred within the container and replace with new fruit peelings and cuttings. Within 3 or 4 days, the swarms of fruit flies will be gone from the house, with only an occasional straggler (or newcomer) to be found. The trap does take continual attention and emptying to work, but it uses no poisons and costs nothing. In conjunction with the use of the trap, you should of course, discard outdoors any fruit on the counter that is starting to rot or become infested, though some can be used within the trap if not obviously infested. At the end of summer, the trap can be retired and you can let your guard down again until the following year. It's simple and it works great. Now if only a similar simple method to clear out the mosquitos and spiders exists. Anyone know of one?
haha, like your style. The hotheads heated comments causing you to make a cooled down version of the video could use a wind catcher. Ah well new video, new views. Keep going, nice work.
LOL Those of us who have lived in the desert aren't bothered by a little dust inside, the stray black widow or rattlesnake, either. Lizards pop up, too.✌😸
(20C X 9/5)+32 = 68F 🤪 You know I saw another one of those mass content channels doing a piece on these and I believe SciShow (PBS) did as well. You were first!!!
We're so spoiled at this point, most of us take our home air conditioning for granted until it goes out, and then we realize what a difference it makes in our lives when it's fixed. Some uniformed people do not understand that this wind catcher technology was the life saving technology that allowed ancient peoples, living in hotter climates, to survive the summers. It was that important, without it, survival would not have been possible, in many instances. Without wind catchers, many ancient peoples would not have been able to inhabit coutless regions of, what is today, Iran. A difference of a few degrees made the difference, between seeing offspring flourish, or being unable to inhabit entire regions, due to the physiological constraints of the human body, in hot desert environments. Air conditioning was glory at its finest, for people living desert lives in this region. And thank you, Kayleigh, you're awesome, stay cool!
Please tell me if a Yatchel or airconditioned house be much cooler if it had a cold underground spring running under the house and used evaporation from that? How cool did a rich person's house with this version of the cooling get?
I have about 2weeks of mosquitos per year now. I grew up in Alaska and all summer full force bugs, so I get it. As a HVAC tech of 20 years I can say You taught me something new today. I also believed my job was only as old as Roman times before today. I also now have a crush on you. Cats and history what a combo! I was very vocal when seeing your face for the first time.

Swamp cooler is what I grew up with in 29-Palms. Best thing since slice bread for that area...
I live in Melbourne, Australia where summer temperatures will often get to 40° C (104° F). We usually have low relative humidity on those days and can get the inside temperature to a comfortable 24° to 28° using only evaporative cooling.
We do get the odd day where it is both hot and humid (like in the tropics). On theses days, the evaporative cooler doesn't do much (in fact, it seems to make it worse). Fortunately, here in Melbourne, they are few are far between.
We all love the open, airy feeling the evaporative cooler gives our house in the hot weather and do not feel the need for any other form of cooling.
You are very beautiful Kayleigh

Hi Kayleigh
I grew up with evaporative cooling ( Swamp cooler ) here in the Central Valley of California.
We are fortunate, in that our summer humidity is very low, except in late July of early August when we have what is jokingly called our " Monsoon Season ". These are a few days when the moist air moves up from the Caribbean ocean, and causes a massive increase in humidity. So for a few days our evaporative cooling does not work, and we simply resort for the cooing effect of moving air. Not verify pleasant, but barrable for a few days a year.
Evaporative cooling is most effective, below 22% relative humidity ( RH ) which is this method of cooling's design humidity for engineering calculations.
While our humidity had steadily risen over the decades, due to massive planting, and irrigation, this cooling system is very effective, both comfort wise, and energy efficiency wise.
( I remember many summers ago, as a child 65 years ago, that the RH was about 5 to 7 % percent )
At mid afternoon we would sometimes have to stop the cooler as it had gotten too cool inside our home, this with an OAT, ( outside air temperature ) of 120 degrees F. ( 49 degrees C )
A properly sized evaporative cooling system will reduce the internal air temperature as much as 40 degrees F @ 22% RH. ( 17.5 Degrees C )
All this cooling effect with the use of a 560 Watts per hour of electricity, ( 3/4 HP electric motor, vs a 3 ton mechanical system using 3.375 KW/HR about 4.5 HP.
Since I hold degrees in HVAC and taught the subject, as well as a MS in mechanical engineering, I have run the numbers many times, and written a textbook on the use of the Psychometric chart.
Any doubters really need to understand the Pyrometric chart, and how to use it.
I know it is a bit hard to understand at first, but as the most difficult class to teach in HVAC, I always had great success, and never had a student fail my class in the subject.
What many folks do not understand, is that evaporative cooling requires that 100% of the air brought in must exit the structure, which is exactly the opposite of what is required for mechanical air conditioning. While it is simple enough to just leave the windows open to achieve this exodus or incoming air. I design evaporative air system to exit the cooled space through " Up Ducts ") that lead into the attic space, and out through the peak vents in the roof, thus cooling a very hot attic space. Thus further enhancing the cooling of the structure.
The definitioning of Air Conditioning is misunderstood by most folks.
Most people have comfort heating and cooling, but not true Air Conditioning !!!
True air conditioning requires that the air in the conditioned space be :
1. Circulated
2. Heated
3. Cooled
4. Filtered
5. Humidified
6. Dehumidified
These conditions are rarely if ever meet in the usual residential or business spaces.
True Air conditioning is only used in climate controlled spaces like metrology labs and places that require exacting control for industrial processes, as it is very expensive to install , maintain and power.
I have studied ancient civilizations, and am always fascinated by the expertise with which the are engineered. While the science of engineering these areas was not understood at the time in history, the ancients obliviously understood the working principals of what the built and were very much in tune with nature, as they were excellent observers of nature.
I couldn't justify being an Archeologist, Egyptologist or Paleologist. While extremely interesting, they could never be justified financially.
I come from the real world of farmers and agriculture, and the necessity of keeping things repaired and productive on a timely basis.
Thank you so much for show casing the ancient worlds science and technology to a whole new generation of folks. These younger people will take this knowledge and add to it, and make ever many more creative and useful things.

Loved the video! Very insightful. I grew up with big fans built into the ceiling of the hallway, when switched on and the windows were opened. They blew the hot air into the attic which had vents on both ends. It was amazing how cool the house was.
Another great example of humans learning from observing animals is maple syrup. 'Brother squirrel' really did teach us.
Kayleigh on the American holiday of thanksgiving. A reason to give thanks!
🤗
I think a lot of folk, don't actually grasp the definition of the term: Air Conditioning = to equip (something, such as a building or vehicle) with an apparatus for washing air and controlling its humidity and temperature(from Meriam-Webster dictionary). Which is EXACTLY what these wind catchers do. People need to stop fixating on air conditioning being a device that can exactly control temperature, or use electricity and/or compressed gas. I find it fascinating that people visiting your channel could be closed minded & view the world through tunnel vision. Keep up the great work Kayleigh :)
Hi K, you won't need air conditioning in England (trust me, I live here). You will need: #1 An umbrella #2 A warm waterproof coat #3 A pair of wellies (yes, i did say wellies 😉). As it is generally cold and raining..or both. We do get the occasional warm summer, but you will survive I am sure. Interesting vid K...peace to ya.
We in the states use window screens to help with the bug thing. I know in England they don't really use them. Idk about where u r though. So if u r trying to reduce the bug issue use window screens. Also for ant problems, sprinkle egg shells around the home...it will help immensely. And then for other bugs, plant lavender around the home, inside (if possible) and outside. And then for mosquitoes, burn citronella candles. Hope this helps. But either way, everybody has some bugs wander in....cuz unless u live in a bubble, it is just a part of living on the earth. :) 😀
Yup...American Southwest swamp coolers...work well. If it's dry enough, in Arizona it usually is.
😉
Two things: one, for humid climates you need the wind to be channeled underground to pick up on the cooling effect of the ground; two, for meshes to be used and not have them constrict the flow below desired rates you need to increase the intake rates to compensate and increase the area covered by the mesh.
Oh it's history time with you again. Talk about a treat on Thanksgiving. I hope yours has been amazing today as well. Happy Thanksgiving, Kayleigh.
Haha thanks! Happy Thanksgiving!
@@HistoryWithKayleigh You're very welcome and thank you as well haha. I hope yours has been as amazing as you are. Truly one of my favorite people on TH-cam.
Personally, I find it fascinating, how advanced ancient cultures were.
They prove that limited technology does not mean limited intelligence. And, without their ingenuity to build upon, we may not have a lot of the things that we do, today.
I can not agree with you more 😉
Try it in humidity . It works in certain places not all
Excellent as always Kayleigh.
Thank you!
@@HistoryWithKayleigh you are a wecome antidote after watching some nonsense on the "History" channel claiming that Leonardo's genius can be explained.....he was abducted by aliens for two years who gave him the knowledge, Oh of course why didn't I think of that?
we in Ontario say ''it is not the heat -it is the humidity'' -we have a lot of immigrant folks from Africa and the Caribbean who cannot believe how un comfortable it is here in summer.
Beautiful voice Kayleigh a swamp cooler works best for very dry places.
Yup
To quote someone "I hate sand. Its course, and ruff, and irritating. And it gets everywhere." Give me snow over sand any day.
This wind catcher sure is your most interesting topic. I like it.
The fact that it was created 5000 years ago is an amazing feet in and of itself! The plus side of not having a thermostat is you don't have to hear your dad complaining that somebody touched the thermostat.
Your enthusiasm and insight makes me eager for each of your video releases. Of course the ancients did need to use ingenuity to make their lives as comfortable as they could. Necessity, as they say, is the mother of invention.
Very true! And thank you for the compliment 🤗
G'day Kayleigh, you are absolutely right this is the first air conditioning, l am a qualified Plumber, and in the dry climate of Australia we use water and wind to cool our homes in the form of evoprotive units on our roofs and ducted to all rooms, water is added to the air for cooling, air is drawn through wet pads on 4sides of the unit and a fan blow cooled air into the ducts, this will reduce the temperature inside between 10c to 14c, so not a lot of difference, the other type is refrigerated which is totally different, hope this helps, cheers Neil 🤠.
🤗
Thank you Kaliegh 😊
Something to think about.. what other technologies would people be dismissing as not anything interesting or new if the library at Alexandria had not been burned to the ground? Actually, if I can make a request… can you make a video about the library at Alexandria?
Happy Thanksgiving kaleigh!
Happy Thanksgiving, hope you have a good one! We don't celebrate it here In the Netherlands (or the UK where I'm currently visiting)
Excelente el video, muy bien explicado, felicitaciones, creo que en la India había un sistema parecido, pero no estoy seguro, tal vez usted pueda investigarlo.
3:45 "I'm moving to England in the new year. And England is known for not having air conditioning so I'm f**ked." - History with Kayleigh. I thought this was funny! But also so true....lmao 😂🤣
Always great to see another video from you. If I may, I know it's an American holiday, extend a Happy Thanksgiving to you and everyone here. Anytime one can gather over food and drink with family and friends is a good one.
Happy Thanksgiving!! 🤗
Arguably, changing the temperature inside of a building is Conditioning the Air.
Air conditioning, often abbreviated as A/C or AC, is the process of removing heat and controlling the humidity of air in an enclosed space to achieve a more comfortable interior environment by use of powered "air conditioners" or a variety of other methods, including passive cooling and ventilative cooling.
…. Did someone think that Ancient Rome had window units?
Some people live in cities on valley floors and notice it's hot there. They travel to surrounding hills and notice that the air is cooler there while it's hot down below. People build towers and notice the same thing at the top of the tower. So, they rig a system to bring that cool air down below. Life is good.
Then, they notice that air that flows over water becomes cooler. So, they do that. Life is better.
They lived happily ever after. 😀
Happy thanksgiving!
Thank you! Happy Thanksgiving
Another awesome job 👍👍
Thank you!
I think these passive, no electricity systems are fascinating and worth looking into--especially in applying new materials and technology to help improve them. For example, one could use vacuum insulation panels, combined with ultra white paints, and mirrored aluminium to direct IR energy up into space, and have a constant "icebox" on top of their roof. And which could easily be converted into a heater in the cold months with a glass top.
When I taught English in Thailand, the temperature was usually 90+ degrees Fahrenheit, in the classroom, with no air conditioning. And I needed to wear a collared shirt with tie and pants. Imagine being on your feet for hours at a time in that kind of heat, shouting over the din of 50 Thai kids until your voice goes hoarse. Yep, it was rough at times.
You did a great job on the first video and on this one as well love ya dumplin !!
As they say “ Don’t let the bastards get ya down”!!
Yeah for AC!! When you live in Texas like me its almost a necessity.
Don’t kill the spiders. They keep it bug free. Around the equator small lizards are accepted for bug control. Keeping that in mind. Anything bigger than a nail? Usher it out doors. Everyone grow up!
Geckos are the best roommates.
@@pattheplanter licking the eyes thing really makes me laugh! It never gets boring! Having a bad day? Eye lick! Dog lost a foot then got lost? Eye lick! Lol
@@pattheplanter you understand geckos can poop upside down! Lol don’t snore!
So I keep hearing that the desert wind whispers across the vast openness. Sounds like it's full of hot air.
As we see the world going where it is going, these energyless technologies are going to be very helpfull.
My grandparents when living near Brisbane had a 'pet' frilled lizard. He (they think it was a he) controlled the bugs. Apparently he just kind of moved in. He was doing no harm and controlling the bugs so they let him stay. This is obviously not going to work in the UK.
Haha nope
lizard poop ewww
I have a couple of gecko's that do the same by me. They eat the annoying insects, and i let them be with no problem. Plus they tend only to come out at night, and make only a tiny bit of noise.
To those who brought up swamp coolers, technically a wind catcher is not a swamp cooler. They could be used together but they are two separate things. A swamp cooler involves a wet surface to cool the air as the air blows over or through it. It's a form of evaporative cooling.
Bugs? Try spraying very dilute eucalyptus, and peppermint oil...a tiny bit in a swamp cooler gets rid of lots of bugs too...ok...OK swamp cooler and wind catcher, same principals...lol.
These Wind Catchers would work well here in Los Angeles and a lot of California. We do get some humidity, but it's rarely high & we pride ourselves on the dry heat here in Los Angeles and most of Southern California....
Hey Kayleigh, I learn a quick method to convert Celsius to Fahrenheit, I was always confused too. Double the number and add 30. It’s not exact but with in a degree usually. So 30C = 60+30 = 90F. 🙃
Another way (that IS exact) to figure cetain C and F temperatures is to use the "rule of 14." 15, 20, 25. 30, 35 degrees C equal 59, 68, 77, 86, 95 degrees F. Notice that the Fahrenheit digits all add to 14 and are symetrical around 77. If you can remember that 25C = 77F, then you know many of the temperatures within the range of human comfort.
Because the digits of 14 add up to 5, there is a similar "rule of 5" that works all the way from 5 F to well above the boiling point of water. The decimal F temps between the whole number temps aren't too hard to figure when you have such a solid framework.
26 C = 77 +1.8 = 78.8 F

Ha good, thanks
A lot of people refuse to realize a lot of the technology we have today has ancient origins
The ancients are great observers, true pillars of our stepping stone to tech ❤
Orchids like swamp coolers.
various plant deter insects.
thank you for the video i enjoyed it ... smiles
Thanks!
This was great technology, and still is, there are numerous places that have incorporated similar system into modern buildings. It is a a means to cool large areas without the need for any external power.
Agreed 🤗
India has a temple that shows how people operate it with ropes and pulleys manually. The columns actually have obsidian cast pulleys on the columns. But the carvings show show people with approx 10” diameter ropes. They put the operating instructions in carvings on the temple. Lol now that’s how they operated over there. Check out Praveen mohan arc reactor temple. Don’t get wrapped up in his interpretation. It’s manually operated when it’s components are missing.
Hahahahaha 🤣
@@MrFlatage the temperatures would fluctuate with that dome, I’m assuming they took into account solar load accumulated then transferred inward at night when it’s cooler.
@@MrFlatage it’s not a reactor. It’s a ventilation system. Operated by humans. But Praveen thinks it’s a reactor. Lol
Hi Kayleigh the easiest way to work out Fahrenheit is say it’s 20 degrees then double it gives you 40 then add 30 then subtract 3 gives you 57 degrees Fahrenheit
....or as termites calculate it (0°C × 9/5) + 32 = 32°F ---> (20°C × 9/5) + 32 = 68°F
Anyone who has a problem with little fruit flies just take a clear jar and add about a Quarter of an inch of apples cider vinegar with one drop of dish soap cover with Clear cling wrap then poke a few holes in the top with a knife. They will check in and won't check out
How fantastic is that 😉
@ 3.50, england has lots of air conditioning. it's in most offices, people like me who work on the factory floor just have to sweat! as for the wind catcher, it may not be "air con" as we know it now, but it makes life better for the residents, and it works WITH nature. we have forgotten far to much ancient / passive technology. even the humble veranda has largely gone now.
Oh yeah i me at airco at home, rarely anyone has that unless they're very wealthy hahaha
Hi Kayleigh, may I suggest you to make a documentary on
1. Bridge between India & Sri Lanka
2. Pangea continent
3. Gengiz Khan
4. Qutb Minar tower in Delhi. How it's never rusted
Love your videos. Very well done.
Why don't you move to Dubai
Anything that keeps the temp 85f when it is 116f outside I will call air-conditioning.
Agreed haha
Cooling in ALL climates seems to have gained headway now that researchers developed radiative coatings that convert heat to the same IR wavelength that the humid atmosphere is transparent to. This actually allows the roof to eventually drop BELOW ambient. I presume most homes heat loads exceed this ability but it certainly helps. Every bit lost at night takes a bit longer for the sun to heat back up in the morning.
Most people still don't actually understand how evaporative cooling works. The water evaporated does not dictate how cool the air feels but the more room the air still has for MORE water AFTER absorbing the intial water dictates how dry and cool the air feels. People in dry West Texas often complain of waking up in the middle of the night shivering from their powered evaporators.
Your face.. you are correct and… Your original windcatcher vid is what got me watching your channel. Tchuess
Thanks
i somehow doubled the earlier comment, so i edited one to start over. hey, Kayleigh! can't wait for the museum video! it'll be great, i'm sure.
it blows my mind that you got so many comments deriding the astonishment of ancient cooling🤯 as you said, i don't think those people realise the extent of brain storming it took to come up with this idea. so many take the modern conveniences for granted. the tv was a good example. other than natural structures or critter behavior, the ancients had nothing to go by. creating wind catcher cooling systems was as ingenious as anything today, for their time and technology. we need to give them their due.
anyhoo, m'lady! i'm so glad to see your lovely face👸 and to see the results of your lovely brain💎every time i watch. come on, people! how can you not subscribe?
Haha 😂
I have mosquitos and spiders in house, besides living on 8th floor and in quite cold and dry area. Apparently they are simply better from us and we need to adapt.

In the locations of those devices, humidity in the air would be desirable.
Agreed haha
How to keep bugs out of the house here in Arizona we or some of us use bug zappers at the entrance of the house i got one on the porch and one un the foyer
Thanks for the video❤️👋👍 I like the educational value and of course your presentation which is modern and refreshing. As for the negative comments from stupid trolls, just smile and start laughing then ignore their meanness!
If you really want to get in trouble, do a video on Trompes.
no aircon necessary in uk btw. twenty degrees is considered a heat wave :)
Kayleigh, you will find the negative opinions of those who watch your informative and interesting videos are Philistines. The cooling technique used here is the best the ancients could do with technology available to them. They used the climate to their advantage. Most of the people who would correct you couldn't get by without their modern convivences. Negative critics are like dandruff, just brush them off and keep on doing this type of thought provoking stuff. :)
One other thing of note is that heat is more tolerable in arid regions, than in humid climates. I rember living in Spain in the city of Salamanca. It was a dry climate. When I returned to the US, to New England, I found the heat intolerable as it was humid heat. I would also go into the big cathedral to enjoy the coolness from the heavy stone walks, listening to the organist practice their music.
I do agree this thing you describe is amazing. Kenots are an amazing nonelectric invention for climate control in that region. It could definitely be applied to modern building in some areas of our country, reducing our use of electricity and cost. Of course it would not be so useful in hunid regions. Humid areas had their solutions.
Some of the comments you tell of are quite disturbing, as they obviously have very little concept of how pre electric people solved problems.
Also, many people of today gave not lived under pre or non electric conditions, so they are perplexed by non powered solutions. They just don't believe they work, when they actually do. I have been fortunate enough to have lived in the out islands of the Bahamas before there was electricity there. The if island and cities, such as Nassau did, but the little island in many cases did not.
As a rough guide to convert from Centigrade to Fahrenheit you double the number and add 30.
So 20 C° becomes 70 F°
Note however this only works over a relatively narrow range.
There is a very interesting book on Iranian desert architecture titled.
'Living With The Desert: Working Buildings On The Iranian Plateau'
By Elisabeth Beazley & Michael Haverson.
It covers the Wind Catchers , Qanats/Kãrīz and Iranian Windmills (The late Michael Haverson who was a great friend wrote the chapter on the Iranian horizontal windmills.
Which are quite unlike European vertical windmills!).
At 9:20 you ask if Any one knows how to keep mosquitos, spiders, & fruit flies out of the house. I have found a partial cure for fruit flies that may interest you. It uses no electricity or other power source. We bring fruit (like bananas, peaches, tomatoes, etc) into the kitchen to ripen and had horrible troubles with the fruit flies they attracted. We found that we could almost completely eliminate the flies with a simple trap. We use a wide-mouth plastic container with its large flat lid, like cottage cheese and some other refrigerated foods are sold in, and put waste pieces of fruit in the bottom. Leave the lid slightly ajar so that the fruit flies can enter. In the morning, and several times during the day, clomp the lid closed and carry the container outside to open it and let the collected flies fly away. Sometimes, you will have caught 50 or more. Every day or so, discard outdoors the fruit being used for bait before new flies are bred within the container and replace with new fruit peelings and cuttings. Within 3 or 4 days, the swarms of fruit flies will be gone from the house, with only an occasional straggler (or newcomer) to be found. The trap does take continual attention and emptying to work, but it uses no poisons and costs nothing. In conjunction with the use of the trap, you should of course, discard outdoors any fruit on the counter that is starting to rot or become infested, though some can be used within the trap if not obviously infested. At the end of summer, the trap can be retired and you can let your guard down again until the following year. It's simple and it works great. Now if only a similar simple method to clear out the mosquitos and spiders exists. Anyone know of one?

Thanks Kayleigh. I wish most people would pay better attention to your videos and wait until the end to make a comment. I do. :-)
We're so spoiled at this point, most of us take our home air conditioning for granted until it goes out, and then we realize what a difference it makes in our lives when it's fixed. Some uniformed people do not understand that this wind catcher technology was the life saving technology that allowed ancient peoples, living in hotter climates, to survive the summers. It was that important, without it, survival would not have been possible, in many instances. Without wind catchers, many ancient peoples would not have been able to inhabit coutless regions of, what is today, Iran. A difference of a few degrees made the difference, between seeing offspring flourish, or being unable to inhabit entire regions, due to the physiological constraints of the human body, in hot desert environments. Air conditioning was glory at its finest, for people living desert lives in this region. And thank you, Kayleigh, you're awesome, stay cool!
Please tell me if a Yatchel or airconditioned house be much cooler if it had a cold underground spring running under the house and used evaporation from that? How cool did a rich person's house with this version of the cooling get?
*MY COMMUNIST WIND CATCHER* works amazingly well here in Bulgaria...
