I love how Dune 2 showed how sacred and important water is to the Fremen. Dune 1 told us it was scarce, Dune 2 showed us.
I wish they showed Jamis being buried in more detail like in the book. One of the coolest moment in the whole book is when the Fremen see Paul crying as they bury Jamis:
A voice hissed: "He sheds tears!"
It was taken around the ring "Usal gives moisture to the dead!"
He felt fingers touch his damp cheek, heard the awed whispers.
Jessica, hearing the voices, felt the depth of the experience, realized what terrible inhibitions there must be against shedding tears. She focused on the words: ‘He gives moisture to the dead.’ It was a gift to the shadow world - tears. They would be sacred beyond a doubt.
Nothing on the planet had so forcefully hammered into her the ultimate value of water. Not the water-sellers, not the dried skins of the natives, not stillsuits or the rules of water discipline. Here there was a substance more precious than all others-it was life itself and entwined all around with symbolism and ritual.
Water.”
Ok* i know thats true tho
So you don't think the big ass fu@$ing endless desert or the fancy water-capture suits wasn't giving big enough "water is scarce as shit" vibes?
Spoiler alert?
@@Astraeus..it's different seeing water as a expensive thing and seeing it as a sacred thing.
The quality of your content is top-notch
except when she mumbles and says half the worlds wrong in the video...
@@TheTctoocoldthat doesn’t happen, stop making up reality
@@TheTctoocold Where-as, you just use the incorrect word.
She is really cute lol
Lmao I wasn't expecting that 😂@@Lee33642
The wind traps in the movie really reminded me of Namib desert beatles. They sit on top of sand dunes and collect water from ocean fog.
And they made great music.
Weren’t they just nets in the movie? 😂
That’s exactly what I was reminded of.
It is inspired by this Beetle
Some lizards do that to. And i remember seeing people take nylon string and make thin webs that lead down into containers which caught the morning dew everyday. Large structures that looked like art exhibits.
This woman’s enunciation is impeccable. I love these videos
Butchered the pronunciation
Annoying vocal fry...
Awful vocal fry. She sounds like shes about to cry and just finished vomiting at the same time. Like every sentence is an emphysemic last gasp of air.
Let alone there is nothing that does this now... show me a working sweating building!! 😂😂😂😂
I randomly found this channel and just been glued by the sheer quality
It’s pronounced “bad-gir” literally means wind catcher in persian
The g sounds like gold not j
An roll that g a little...
But there is no g sound in arabic
@@Ihsaan_ASMR it’s persian not arabic
Arabs say it barjil but that’s what they do with every foreign word
@@chrisbaled7471 okay I was confused because in the video it's written in arabic
@@Ihsaan_ASMR modern Persian and Arabic share the same scripts.
You make architecture a very hot subject which is already cool on its own.
Bro you are nott the riz
san Al gaib
Frank Herbert had significant knowledge of Arabic culture and how desert life shaped it. No doubt he knew about the barjeels and incorporated a more high-tech version into his story.
Baadgirs are Iranian not arab.
In the ecological reclamation of dune they also have qanats everywhere.
He also was well research when it came to desert ecology.
The problem with giant dehumidifiers is that there is not much moisture to begin with. They wok great when you have a lot of water in the air but you are going to have it anyway in that case.
Barjeels are sooo smart. I wish that they were more common, but Idk whether environmental conditions make that impractical in some settings (where we would want interior cooling).
I actually did an hypothetical project to study the viability of wind catchers in newer building. After working out the cost of construction to Return on investment and design criteria to make the process functional, I concluded that a lay person would not be incentivised to build such a structure as it's cheaper to cost of air conditioning with cheap solar energy. I'm a practicing architect so I was actually very eager to try this in a project but I was quite disappointed I couldn't do it.
@@xaviersiby4801: That is indeed disappointing. But that just goes to show that, as a species, we have progressed and improved our technologies. It would have made sense as a solution, it seems, even one hundred years ago. But, now, we no longer need it.
@@curtiswfranksvery well said.
Bro, it's just ventelation😂😂
@@D__Ujjwal agreed it is. But evaporative cooling coupled with stack effect results in much higher heat dissipation can just regular ventilation. Besides, avoiding windows that directly open into rooms, reduces heat gain from solar radiation.
Btw, "Qanat" (Or more accurately Kanat) is the Arabic word for "Canal". The "T" sometimes can be silent depending on the grammatical context.
"Barjil" on the other hand is an Arabic adaptation of the Persian word "Bad-gir" which means "Wind catcher".
So, the Wind Catcher works by funneling air through canals (channels). 😊
Bâd-Gir with a hard G as in Graphic
Kir in Persian is the vulgar word for a male reproductive organ, kindly do not use when speaking! Or enjoy the reaction if you chose to do so! Lol
@@rusbea.2279 I'll correct it.
Wow! This is a rare occurrence as they said on The Good Place! Like a double rainbow
When we lived in a trailer park in southeastern Arizona, we didn't have air conditioning, we had a "swamp cooler" which was this metal box of a contraption that sat on top of the trailer roof in the center of the hallway and would circulate humid air that had been cooled in order to regulate the temperature the inside of the trailer. I think there was something practical about the way that it would operate that made it so that it only worked if it was hot enough outside, but we would have to manually control the fan that helped the air move a little bit more, but other than that it was a very "simple machines" style of cooling a house. Pretty good for off-grid and low energy consumption. My parents live in Arizona now and while they don't have a trailer with a swamp cooler, they do utilize the cool air of the dry desert nights and open windows during the night and close them before it gets hot during the day. Though, I have to say, during the two years that I lived with them at the end of high school in that house, it was a little bit too cold and I didn't have enough blankets because I would wake up with a sore back every morning, aching all over from shivering to sleep. If I had been more in tune with my body and willing to acknowledge that there was probably something that could be done to make things better, I could have told my mom that I was cold, and my parents would have gotten me more blankets, or maybe even an electric blanket (like the one that I have now). It's okay though. I think I'm kind of processing stuff that happened in my childhood that was not my parents' fault, and sometimes it feels like everything I learn about the world just reminds me of things that were unfortunate in my upbringing, but I always want to see the bright side. I'm kind of actually realizing that this video was more about getting the moisture that is already in the air and taking it to be used as water, and not about using water in the air to cool it down, so maybe I'll just... Nah, I'll post the comment anyway, swamp coolers are still really cool. Lol
I kid wanted to say I really appreciate this comment.
Came for the off grid tech...not for the emotions 😢
Damn you, come here and get a hug
It's not that it won't work if it's not hot enough outside; they won't work if it's too humid out. If the humidity is high, they can't evaporate enough water to cool the air. That's why you can use them in Arizona, but they're useless in Mississippi.
Thank you for not deleting the comment (:
You need help.
You are so great at explanations. I could listen to you for hours. Love the tee shirt by the way.
What a coincidence, i just learned this for my architecture exam and i find i very interesting, now i saw this video👍
Americans in the SouthWest are wondering why they never had this perfectly reasonable tech, when they realise they have been lied to because the energy companies want them to pay for electricity LMAO
I love how I learn something every time I come upon one of your shorts! Thank you!
Great video, thanks for your hard work.
Gotta say, your knowledge of architecture is absolutely amazing.
Conduit buried below eighteen inches in a humid area usually does this if the access isn't weather sealed. I have watched crews use compressed air to blow the lines out to work on the service. You can get an impressive geyser from a large enough pipe.
Love your work....keep up the good work
Dune also has qanats running through places in a sietch, though thia is more common in Children of Dune once water scarcity is greatly reduced and so water rituals are relaxed
I stumbled upon this channel and instantly subscribed. I love stuff like this.
As a geographer I really love how this world is described in the books - it just makes complete sense considering environment they need to survive in.
What I didn’t like though was walking through desert at daylight in the movie. Or using very see through materials to hide from the sun.
really cool!
Wouldn't the air on Arrakis be extremely dry or how would there be water condensation?
This is where I think David Lynch's Dune (1984) nailed it. When Paul & Jessica are first introduced to one, you see and hear a single drip... It was a very slow process that spanned generations... highlighting the religious significance of water.
It's been a while since I read the book but I believe Arrakis still has polar ice caps, albeit extremely small ones.
@@tinlizziedl001 the scene that shows the chambers holding the pools of water...the significance of that is amazing.
@@digitaljanus Yes, but, it states there is no rainfall, no standing bodies of open water, and negligible atmospheric moisture that can be reclaimed. That leads me to think the planet Arrakis isn't tilted like Earth, and with it's orbit, it has a fixed atmospheric circulation.
In the Dune novel, Paul promised to use the resources of the empire to set up a network of weather control satellites to bring rain to Arrakis. The sequel novel mentioned that the planet actually started having casualties from flooding. Also the sandworms in their larval stage as sandflukes (I forget if that was the name, it was ages when I read it) consume vast amounts of water before they enter their worm stage where water becomes poisonous, so it wasn't completely an atmospheric issue. A later novel, the Bene Gesserit transform their homeworld into a 2nd Dune by importing the sandworms over.
I can listen to you for ever. Because your voice feels so enjoyable to listen to not to discount how educational. You ought to teach our generations.
This is so cool, thank you for existing and sharing your knowledge/research in such a cool way.
This is already done in the Atacama desert, catching fog coming from the evaporation of the Pacific ocean.
I just found you this morning and I’m obsessed!!!!
Dude humanity is so awesome for discovering and making this technology.
A friend of mine did his senior project on a small scale one of these that they want to deploy to areas in Africa. It is a really cool idea.
This reminds me of something that was started in Africa a few years ago called Warka Towers they are built and maintained by local people with materials that are easily attainable. These are passive systems that don't need electricity.
the funny thing about desert planets is where this moisture in the air is sposed to come from.
Yeah, once I was younger and more inspired, so I've evaluated such a project for real-life country like Kuwait, SA or similiar arid country near the sea. Well, you need a tremendous temperature drop to reach a dew point because of low relative pressure of vapor in desert, so that's more like "cartoon physics" in sci-fy.
Dew catchers are used in the Atacama Desert to extract moisture from the air at night and collect it for use during the day.
They are simply a piece of shade cloth with a gutter underneath it to collect the condensation.
The Atacama is the driest desert on earth with no life (even microbes) in places because of the aridity.
The Zion National Park visitor center is the pictured blueprint! Very cool
I love that barjeel qanat set up. As the world gets warmer we're going to need solutions like his for our AC. Ancient tec is so clever
Very interesting information and content. So awesome to now know, DamiLee. 👍
It's true, they also use domes for better air circulation so the hot air would go up and away from top side vents and leave the colder air down
AND they look so cool!
So cool! Loved this.
The structures are also visually reminiscent of an Iwan, a Persian architectural feature that captures and funnels the wind downwards.
would someone who has actually experienced BARJEELS comment on just how Efficient they are? Lots of hype, but what's REAL!?? tanx! :-)))
The wind catchers were also the design behind Rome "refrigerators"; essentially, they were buildings built in a place that catches wind, which was pushed down a vertical chamber. At the bottom, foodstuffs could be kept, then topped with a layer of some kind of plant matter, we don't know what. There may have also be snow and ice packed in below the food, but that is debated.
The foodstuffs would be packed in during the early winter, and were used primarily around the Mediterranean's north coast, we've found them in Italy, France, a couple in Switzerland, and along the coast of the Balkans. This meant that the food packed in would stay cool for months at a time, with wind blowing into the chamber removing any air that had heated up beyond "just above freezing".
They seem to have been used for grains and vegetables, to keep them just above freezing, because freezing (unless flash frozen) breaks down the cells of plant matter and makes them more susceptible to bacteria (and thus spoilage) once thawed back out. So the grains and vegetables were refrigerated, kept from freezing, but also kept from warming enough to spoil for months on end.
They seem to have gotten the idea from Greek conquest of Persia, as we don't find them before the 3rd century BCE AFAIK
in the Southern US a dehumidifier the size of a football stadium could give a whole city all the water it could use. Damn 94% humidity days.
There’s a building in Melbourne that has a system of underground tunnels that pass wind through to cool the air too.
This and you are awesome.
Ingenious. Thanks.
Def want a cooling tower for my home.❤
Thank you for mentioning these. The last time I saw them was in Architecture School in the mid-70s. We had a lot of Iranian students before and during the revolution.
Star Wars vibes
Problem is that in a hot and arid enviroment the air humidity is likely very low which means that vapor condensation is very inefficient.
Dehumidifyers works best in humid conditions. And that tends to be in areas of the world were water i not scarce in the first place.
Somewhat true. But there's a difference between relative and absolute humidity... Hotter air can hold a lot more water vapor, and 'dry' hot air usually becomes humid cold air when cooled. That cooling takes a lot of power though, which is why "water from the air" products are pretty much a scam.
However, when you have lots of energy but little available water, they do make sense.
PS: I'm guessing you've seen some Thunderfoot videos? ;)
Amazing!👏🏼🙌🏼
I always thought that wind catchers' main issue is in how they manage to force hot hair down into thecold cavern where cooler and denser air is...
They should work in areas with very stable wind direction but require big air nozzles making them very hard to disguise.
I recognize the design from Take on Mars, it's great to see how different Sci-Fi media portrays the same principle almost identically solely based on science.
In Chile, Atacama desert, they used 'atrapanieblas' (fog catchers), that works in a similar way.
Another great video ❤
As it was mentioned in Dune II: Harkonen's water from their bodies could only be used as water coolant. I suspect that this water was used to cool the coils of the wind catchers and help the condensation.
Two types of technologies that use the wind catching technique. 1. funnelling warm moist air underground, where cooler temperatures (below the dew-point) extract water (mass of ground can absorb all the energy released) 2. warm dry air is passed over a wet cloth (high in a structure), which cools the air through evaporative cooling. Typically the defending air escapes lower down in the structure.
Not familiar with the closed structures shown in diagrams here; but it's possible that gusts of wind create a cycle of pressure in the structure that act as an air pump. Since are is coming from above a hot ground it would be cooler than air at ground level. Placing a damp cloth (as in #2 method above) would work to cool the air.
It would be interesting to see internal to the tower structure. Is possible it could have been reconfigured from different seasons?
This is such an awesome channel!
I have a chimney to an old gas fireplace. A wind catcher sure would be nice.
This can be high businesses. Cool air and water makes lives possible in the desert!
That section was the Zion National Park visitor center.
Hey! That's what they used in the castle in Spain
I need this in my new house when I am gonna make it
I can't rely on electricity as it is prone go off frequently
Solar panels with battery system are the answer! With this system you are dependent on wind...
If you are designing/building a house and interested in making it efficient and/or less utility dependent... Look at "earth ships". I'm not saying you should build one, but there are several neat design features you might use and adapt.
Also, for the love of God, put floor drains in the kitchen and bathrooms ;)
Take a look at the CloudFisher fog-collector in Morocco, that produces water from fog.
If it wasnt so cold where I live I would try that
A mix of old tech and new tech. Cool.
Exactly like an ac unit. Every air conditioner has a system for dealing with condensation. They can collect up to gallons of water in an hour.
We are not the same generation and I've less than not enough on any level. So why do I fall in love every time I watch another one of your videos? Um should I not feel humbled enough with just how sincere I feel, I must tell you that I feel grateful for your talent very well produced video.
Intrigued to know what designs would be used in an opposite fantasy world - where it is constantly raining
Just visit Florida ;)
Seriously though, they would probably heat up the air (increasing the amount of water vapor it can hold and thereby decreasing the relative humidity), and then use that to 'suck' moisture out of the air for the living spaces.
The first modern-ish air conditioner (by some metrics) was invented to control the humidity in a printing shop, and worked that way.
Alternatively, you can cool the air to wring moisture out of it, then heat it back up to get dry air.
All that said... Animals which thermoregulate by evaporating water from their skin (aka sweating) are pretty rare. So the high humidity might not be a problem unless you're dealing with humans.
i love your channel! so glad i found it randomly doom scrolling!
It is mostly based on Persian windcatchers since Herbert created lots of Fremen words from Arabic languages. It draws many similarities, including their described clothing and the ancient equipment for preserving water.
In certain parts of Iran I saw these wind catchers and also in algeria
Yup we need more passive technologies to reduce the waste and green house gases.
Absolutely brilliant.
I got to see ancient wint tunnel towers when i visited Iran! They work really well. Ancient air conditioning.
Loving these Dune videos. Herbert was truly a madman
Yeah, Persians had rudimentary A/C in 1000BC because of the qanat/wind catcher effect. It's pretty amazing we don't use this in the desert southwest ...anywhere. confident this would work in the not-so-dry ecosystem of the Sonoran and Chihuahuan deserts.
I enjoy a lot this channel!
If nobody's mentioned it, Dune originally started as a book about changing the landscape of the California desert, so much of the Fremen ecological toolkit has a basis in environmental science.
This is one of the best channels I've found in years.
God I love to hear smart coherent words
We lived 'Off-Grid in AZ and had to haul water ~ we bought a "Kara" Water extractor ~ it can pull 10 ltr of water from the air a day. . .
I think I literally love you. Your content makes me waste to spend hours watching all these shows.
Great idea, but wait, how does it only allow wind to go in where does all the sand go?
your content is very informative and I love that accent lmao
This is so interesting 🎉
Ac’s evolving backwarda but in the right direction🤯🤩
Dang, I want a barjeel. That's really clever
Their is something know as air wells aswell
She is the Lisan al-gaib!
In Emperor: Battle for Dune they produce power. "Low Power. Windtraps required."
Stepwells in India and neighboring countries deserve a mention here.
Love your voice
_I bless the maker and his water, I bless the coming and going of him. May his passing cleanse the world._
I got mine at Toshi station!!!
Thanks 😊
The water catching part of this made me think of Thunderf00t's "Waterseer" busted video.
So, kind of like a reverse heat pump that uses atmospheric heat (or even potentially heat from deep underground) to heat homes & military/corporate complexes?
Thank you.
