Somaliland means “ the land of Somalia” There are 5 main tribal residents in that region which was under the coloialisation of Britain, most of the Somali tribes fought against Britain forces and took their freedom. Somaliland United with their brothers in the south somaliland who got their freedom from Italy and formed Repulic of Somalia. Somalia went through a civil war fueled by foreign powers who wanted to suck vast economic resources that Somalia has. Isak tribe, which is one of the five the tribes in Somaliland is being used to claim that they represent the whole population of the somaliland by subjugating other tribes, and therefore fulfill Imperialistic agenda. The so-called Somaliland authority (SNM) sold ports, and many other Somali resources to the same foreign powers that installed them. The part of somaliland these junta control are suffering from all kinds abuse. They can’t speak freely and they are subjugated to obey the harsh Jeegaan rule.
Awesome invention! I am an environmental scientist myself and I would love to see how financially sustainable this project is. It looks very promising to me.
To realize this, walk into a warehouse that is cooled by evaporate cooling in the summer. At some point, the air gets so hot that it just ends up evaporating so much water that the air becomes humid. While that sucks for us, the air becomes humid and that's moisture in the air for plants.
as easy as it sounds but it's not. it has a lot of maintenance. the cardboard needs to be replaced every time, hardened salt will eventually block the air passage
Not genius at all... poorly copied of things already in existence. - Sundrop Farms in Australia got operational with a 20 ha. seawater cooled semi-closed greenhouse... with indeed the same pads as used here (the horticultural industry calls them pads and not corrugated cardboard walls, LMFAO on that one). - Pad&Fan greenhouses have been in existence for decades... Nothing new on that part. - Using seawater is just not recommend as... they do salt up and that does create issues, regardless of what they said in their article. So, nothing new.

What happens to the card board walls after they salt up? How often do they need to be replaced? How does this affect the cost? How do you dispose of the salty card board material in a closed cycle way?
Exactly my question. They made it sound so simple but the cardboard would salt up so quick! Secondly, I remember loving in saudi and using desert coolers to cool our houses. They work great in dry hot climates but in humid coastal areas where the salt water would be most available, those coolers didn't work at all. It would make more sense if they use the sun to distill sea water to irrigate crops.
One idea is to use the salted cardboard filters as building material, a type of drywall. I haven't seen it in extensive use but I have seen prototypes.
Oh my goodness !!! Something positive and so useful for masses of people on the planet, why isn’t this talked about to the same level as the doom and gloom we get every day ?
why isn’t this talked about to the same level as the doom and gloom we get every day ? Gloom and doom (aka blood ad guts) has been the leading news of the last several millennia, since people associated in large communities. Most media now is profit oriented, whether that is print news or on the internet. Information is out there, but the "news" doesn't seen information pushing viewing. Gloom and doom does.
Possibly because the "cool house" benefit isn't 10-100x less water (for the whole system, not just the crop- cooling paper walls also use water and probably can't run on saltwater) as they claim, and it doesn't make desalination economically viable. Or it's being tested. Still, the 10-100x claim seems too good to be true.
Its not because its not worth it. 1, ongoing costs = carboard replacement, water pumps maintenance (salt water degrades metals faster then fresh). 2, set up costs one off so not really worth mentioning, but plastics for cover, cost of equipment. 3, skilled farmers, its a country that does not have a lot of farmers experienced with the crops it could grow, I imagine training incentives would be needed. 4, lack of control, the system is almost enterally dependent on the outside. 5, does not reduce the cost of growing crops, only makes it possible to grow eg a lettuce grown overseas will cost 30 cents to grow it will still cost that 30 cents plus this set up on top of that. I would argue it would cost more then that due to lack of resources for farming. I view it like oil extraction, there are processes that are really expensive but because they are not economical viable they are not off the ground. Real world its got to make someone money to be worth doing, this does not do that so investment is not going to happen.

I didn't even think about usint seawater to humidify the crops... But this guy showed us the way to combine evaporator and seawater to cool down the crops, and they might even change the climate somewhere in the future!
I've been working on something similar using solar desalination to produce salt while providing water to my plants. Good to see this. I started from the perspective of resources at hand and potential salable commodities. The value of the recovered salt offsets the water production . Before going solar it cost me 72 cents a kilo for the salt and this included the waste by product of 15 liters of free water
To all the negative salty people here ( pun intended ). The salt would build up yes. The next step would be to convert that into sellable salt I would think. 2nd this is the entire point of research and development. Research means to use the salt productively and perhaps use those funds to pay for cost and maintenance. Develop better cardboard to have less frequent need to replace.

This solution has been available for many years, I wonder why it is now that it is gaining traction. This is true for the US and other country with large deserts.
Love the idea! Use of solar powered pumps to pump the seawater inland would green the project further. The. Seawater could be distilled via the desert heat to produce fresh water for irrigation and salt to sell. Brilliant!
Been using the gravity fed water closed loop system and fan cooling in greenhouses for cooling and humidity control since the 1970's that I know of. These cool houses were old then. Probably built in the 1940's. Used to cool plants before flowering to get them to have larger buds and then move them to hot houses to force the bloom all at once for sale. The plants would gradually bloom without this process. The full blooms at once obtained a better market value. The system I worked with used 4' x 4' vertical filters like green scrubber pads with larger openings. They were easily cleaned and reused.
Nice way of doing things. It would work really well if the salt didn't contaminate the soil from using a big cheap swampcooler. It might be better to recycle glass and aluminum into passive desalination panels, and reform plastics into drip irrigation pipe. It takes a lot more land, but in desert areas thats ok. Also, I suggest doing permaculture swales, with drip irrigation for trees, and only using plants with light green leaf coloration to reduce temperature in the local climate. Things like date palms, pistachios, even pecans, almonds, and edible cactai, and hardy soil fixing cover crops like barley. Barley straw would be a great starter chop and drop, to add soil carbon and water preservation. Eventually a fast growing chop and drop plant like moringa, or sorgum-sudan grass, or lemongrass, or perhaps a local desert plant, or something like mesquite, would need to be used to feed the soil. Even cassava could be used for a chop and drop soil protection. The best idea though is barley. Harvest the tops, then use a roller to flatten it down, and resow for the next season with a roller seeder. After a few season there will be a dense vegetation mat with plenty of nutrient for tree varieties. Continue replanting barley as the trees grow, and when the trees are big, plant something else that's fire safe, like beans, or peanuts, or continue with barley. Vegetation attracts and holds water, if the right plants are used. Just don't let any animals graze after harvest for a few years. 5 or 10 or so, and when and if you do, practice migration pattern grazing.
What a great Idea. In Holland Duch farmers in Freezland have developed crops which can be irrigated with dilute salt water 50/50. Some can even be irrigted with salt water alone apparently. All done by years of natural selection for salt tolerance.Good crops of potatoes are now being grown on land in Pakistan formally too salty to support normal plants.

For once, and really once, I think technology has a real interest in agriculture and food sovereignty. This kind of technology should be used to recreate water self-sufficient micro-zones as oasis. The greenhouse would be a tool to build a cultivated ecosystem ALSO outside of the plastics. With desert adapted trees who can create micro-climate, making a cooler atmosphere above their boughs, build healthy soil with organic matte rproduced, and making agriculture possible over time.

In the Sahara Desert there are no clouds because no air vapor turns into clouds but I found a strange appearance in the middle of the Sahara Desert in the Niger region there is a small collection of clouds passing in the middle of the Sahara Desert of the Niger region and then watched closely there is a dense forest under the clouds Located in the estuary of Mount Air Mountaint which often gets annual light rain and the water is sponsored in a puddle in the valley until it turns into a forest. The Sahara Desert is making an artificial forest in a border valley (ridge) as wide as 20 km long and repairing rocky hills in the middle of the Sahara Desert. When it rains on the mainland, it is an ancient river upstream, the air will automatically return to the ancient river which dried up thousands of years ago, shifting the earth's axis

Is the water that's stored potable, or able to be made potable? I could imagine a solar powered OSEC unit being used to convert brine to sodium hypochlorite which can be used to treat any excess water for potable use. You could also install other solar thermal applications alongside to increase yield of water when conditions allow.
Hi David! Good thoughts and thanks for asking. The folks at Seawater Greenhouse actually elaborated on this a bit in some of the other comments. To quote from their responses to Rachel Bell: "Evaporating seawater to create fresh water vapour in our greenhouses cools and humidifies the air, reducing irrigation requirement around 10 times. We produce around 2-4 cubic meters of fresh water per day to service our farm in Somaliland..." "We use the brine to produce marketable, culinary grade sea salt. So no water is pumped back to the ocean!" Hope this is informative and thanks so much for watching!
Brilliant... not only that the water cools the air, but also humidifies it by evaporation, and this humidity is also being absorbed by the plants, needing less watering...
Interesting, yet leaves a lot of questions… some: - is the same salt water constantly recirculated ? - spent water goes where ? - how long until the evaporator wall gets clogged and needs replacing ? Etc.
I recall reading about water irrigation schemes in Australia using artesian wells and pumped ground water to irrigate crops. The water had mineral salts in it which eventually accumulated in the soils due to evaporation and ruined the soils eventually. A similar sustainability problem could exist in this scheme. Regarding the present security situation in Somalia, how do you prevent warlords and their gangs from destroying these greenhouses?

If the sea water was blown into a chamber with clear plastic, the sun's heat would cause evaporation this desalination would occur. A cheap was of desalination.
Your idea needs far more space than the system in the video. Their trick is to produce extremely humid air inside the greenhouse, so the plants need only very little fresh water.
Good question! "Nutrients harvested from the brine are pumped back into the irrigation system to fertilize the crops, and the rest of the salt is made into gourmet salt crystals that Seawater Greenhouse Ltd. sells." -blogs.ei.columbia.edu/2011/02/18/seawater-greenhouses-produce-tomatoes-in-the-desert/
Excellent way to cool and add moisture needed for temperate plants to survive in hot dry climates. Shade houses are used in our area with wall of evaporative media, wall of fans on other end. More complex but more amazing Sahara Forest project is enclosed with fan wall opposite evaporation with CONDENSER pipes to extract distilled water from saturated air leaving greenhouse. Cool moist exhaust air from greenhouse allows many other plants grown outside to do far better than in hot dry ambient air.
if you extract much vapor the salinity would quickly rise - but seaweed by its nature is designed to keep salt out, interesting to know where the limits are (one economic two function)

Great question! From the Science and Development Manager of the Sahara Forest Project, another one Seawater Greenhouse is helping build: "The cardboard evaporative pads will need to be changed out eventually, but not often. In the early Seawater Greenhouse built in Oman, the original pads were still working after more than two years. When they do require replacement, the retired pads will be re-used - potentially as building materials." More info: blogs.ei.columbia.edu/2011/02/18/seawater-greenhouses-produce-tomatoes-in-the-desert/
Hello! The pads last up to 7 years or more. Calcium build up on the cardboard actually helps to increase the lifespan of the material by giving it structure and rigidity.
When you consider the canaria islands, big holiday destination for Europeans, get the majority of their water from desalination it shows that desalination plants can produce enormous amounts of water. A huge desalination plant near the sea and a few hundred miles of pipe and you can create lakes inland in desert regions which in turn, once filled, can be used to green the area
Per an article in The Engineer (www.theengineer.co.uk/greenhouse-uses-seawater-to-grow-crops-in-arid-places/), the cardboard is designed so that “Salt and other minerals collect in the base of the wall where they can be harvested and sold.” So the answer appears to be that the cardboard doesn’t need to be replaced.
Im wondering how much water theyre actually having to use in the place(s) that theyve implented this. Is there data for that? Guess ill have to investigate
Good question: there's some information here: blogs.ei.columbia.edu/2011/02/18/seawater-greenhouses-produce-tomatoes-in-the-desert/ "The Sahara Forest Project will use water from the Red Sea in seawater greenhouses to produce fresh water for the crops and grow algae in open ponds for fuel and food. The project will also grow halophytes, plants tolerant of salty conditions, that have potential to be an energy crop. Because each 10,000 square meters of seawater greenhouse evaporates 50 tons of water daily, the greenhouse will help restore vegetation on the surrounding arid land through ventilating the “lost” humidity to create a cooler and more humid micro-climate downwind of the greenhouse. The “lost” humidity will also increase the chance for precipitation in the area. The algae, crops and other plants will sequester carbon dioxide from the air. Extra fresh water produced by the seawater greenhouse will be heated by a concentrated solar power plant (CSP), generating steam that will turn a turbine to produce electricity. The CSP’s excess heat will be used to desalinate seawater for drinking water. A single Sahara Forest Project facility with 50 MW of concentrated solar power and 50 hectares of seawater greenhouses would produce 34,000 tons of produce, employ over 800 people, export 155 GWh of electricity and sequester more than 1,500 tons of CO2 each year. If the demonstration project is successful, Aqaba will provide 200 hectares for a larger scale facility."
Hi Rachel! Evaporating seawater to create fresh water vapour in our greenhouses cools and humidifies the air, reducing irrigation requirement around 10 times. We produce around 2-4 cubic meters of fresh water per day to service our farm in Somaliland
salt is water soluble, so it would remix with the water, after enough time if the salt is able to built up to silly levels it can be scraped off and sold or used.
that was exactly what i was thinking, everyone says we will run out of water, but water doesn't just go away from earth it just goes in seas and oceans, and humans can develop a technology that removes salt from sea water using the principle of (evaporating/vaporizing and condensing the water).

Hi Julien. Concentrated brine is collected and harvested to produce sea salt that is sold to market. Some calcium can build up on the cardboard, which helps give the wall strength and lengthen the life of the material. Every once in a while the calcium must be dissolved.
In the Philippines , many small Islands have trees and coconuts. They are naturally mainland plants but how are they getting the regular water when they are practically surrounded with salty sea water. those living plants must have evolved to be able to filter salty water.
It's no scam, I saw a very small scale trail of this method in Cyprus in the 1990s - it works brilliantly. Then they weren't usinv solar power for the pumps, just an old 2 stroke deisel(which were still widely used then to pump water from boreholes). There it was set up close to the beach and make use of the predictable onshore winds.

Lol nice but maybe take the trolling to a different video. Most people here won't get that you're joking please I pray to god that you're being a troll
I live less than 5 miles from the Great Salt Lake. One issue I imagine here is that running seawater continuously through a cardboard "swamp cooler filter" will clog that filter with salt in a relatively short period of time as the water evaporates from it, necessitating the replacement of the filter. Is that this corporation's business model -- to sell a lot of filters? Or is there some component in this system that will desalinize the water before running it through the filter? Because desalinization of water at the rate I'm imagining for a system this large may also tend to be pricey.
The cardboard I not a FILTER! It’s merely a medium to distribute the water to a large surface area for it to evaporate into the air. Actually, this would work for desalination as well. Most of the work of desalination is getting the water to evaporate. You can then cool the wet air to condense the pure water out of the air. This method uses a large surface area to do this and the ambient temperature, instead of a lot of heat to boil the water. The question remains what happens to the salt and wet air? Is the salt collected? Does the wet air stay in the ‘cool house, or does it get exhausted. If you did this of a large scale, could you humidify a desert? What would that accomplish?
The answer to both fresh water shortage and reliable crop management, we pray that this kind of tech is applied and implemented as much as defence related work. When everybody has food, no need for wars. 🤔
As an Islander who import almost all pur food. Our land is dry, coraly, and salty almost accidic. This would be amazing! To reduce the temperature and amount of water needed.
400M USD is a drop in the bucket. The problem with many parts of Africa is that there are too many people who are bent on destroying anything that benefits someone they don't like, so even if the West decided to give this facility to Somaliland, some crazy guy is almost guaranteed to destroy it sooner or later. It is not without reason Somaliland looks the way it does. And just to set the record straight, I have nothing but sympathy for those who live under these awful circumstances. We would just need to find a solution that could ensure that won't happen.
You don't have to accumulate any salt to make this work. Sea water contains on average about 3.5% salt, which gives you a lot of evaporation until your solution is saturated (~26%). So you have to replace the water before it reaches that salt concentration, then salt built up won't be a major issue.
I’m all in and I love this idea. I wonder if non-GMO seeds and/or even the seeds of indigenous wild herbs and edible plants (food) can be planted using this method?
I like the idea that possibly the cardboard could be made from recycled paper as well as recycling the cardboard used. Add to that packaging and selling the mineral byproducts removed from the water and the whole idea is pretty awesome. I hope further investment will be made to bring this technology to financial sustainability.
I think the best bet is to use the incoming tide to fill a still. Focus the sun on the still via mirrors. Have the steam exit high into a cooling condenser and let the water flow by gravity to where it’s needed. No moving parts.
Any thing that involves sea water in this manner will cause it to produce heavy brine. Most dump it right back into the ocean. Over time the area becomes toxic and almost all sea life near the shore dies. This has happened in many areas where there are desalination plants. This is the main problem with using sea water in any process that condenses or evaporates.
True costless desalination : Build a huge greenhouse dome by the sea water, pour in water to get heated under the sun, collection evaporation for clean water, collect salt once dry. Put geothermal heating pipes as well. Initial cost: about the price of a green house. Maintenance costs: almost nothing, just cleaning could be paid selling the salt alone.
One problem is not addressed, the salt from the seawater. Another very promising video, a solar dome, uses a greenhouse dome and tunnel to warm and condense seawater. It's an ecological variant of typical desalination plants that use fossil fuel. But either way, every two liters of seawater produce 1 liter of fresh water and 1 liter of brine. You can probably dump it back into the sea, but not close to the water intake point (or the water will get increasingly saltier). Also dumping the brine creates such high levels of salt that it's harmful for the local eco system. If you can somehow disperse the brine or get it to a fast flowing current that might be solved. But transport of bulk volumes is costly. Probably two separate very long green house tunnels, one to draw seawater, one to transport the brine can solve the problem. Maybe not concentrate the brine too much, and just draw a fraction of a huge flow of seawater could prevent ecological impact. I think if that problem is solved, this fresh water produced here can use the technology in this video for cooling and providing humidity.
At the beginning I thought the greenhouse was to evaporate the water, taking it apart from the salt and then used to irrigation. This looks pretty cool. One material that will be very important for things like this is graphene.
Great idea. I wonder what the cost would be like to repair and maintain this would be? I bet once they are producing enough it would pay for itself to be maintained. Is the soil fertile enough to grow a good crop?
Heard of growing crops in an underwater greenhouse, situated near the surface of a warm, shallow sea. It would take the form of a waterproof dome. Evaporation would condense onto the glass, to be channelled to the plants. More hi-tech than this fine idea. Have not heard of it's application.
As a Somali i am greatly interested in these technologies that deal with food production in whats considered unsuitable environments. I research a lot, specially the use of sea water. I can't say how happy I am to see such a project in Somaliland.

Somaliland means “ the land of Somalia” There are 5 main tribal residents in that region which was under the coloialisation of Britain, most of the Somali tribes fought against Britain forces and took their freedom. Somaliland United with their brothers in the south somaliland who got their freedom from Italy and formed Repulic of Somalia. Somalia went through a civil war fueled by foreign powers who wanted to suck vast economic resources that Somalia has. Isak tribe, which is one of the five the tribes in Somaliland is being used to claim that they represent the whole population of the somaliland by subjugating other tribes, and therefore fulfill Imperialistic agenda. The so-called Somaliland authority (SNM) sold ports, and many other Somali resources to the same foreign powers that installed them. The part of somaliland these junta control are suffering from all kinds abuse. They can’t speak freely and they are subjugated to obey the harsh Jeegaan rule.
Awesome invention! I am an environmental scientist myself and I would love to see how financially sustainable this project is. It looks very promising to me.
To realize this, walk into a warehouse that is cooled by evaporate cooling in the summer. At some point, the air gets so hot that it just ends up evaporating so much water that the air becomes humid. While that sucks for us, the air becomes humid and that's moisture in the air for plants.
Have you heard of Sundrop, Port Augusta, South Australia?
Please, can you tell me, what are they going to do with the salt remained.?
@@aldomarioravinamayorga6804 The brine that is left is made into salt and sold for a profit.
as easy as it sounds but it's not. it has a lot of maintenance. the cardboard needs to be replaced every time, hardened salt will eventually block the air passage
so basically they are using a swamp cooler to grow crops. Genius imo.
essentially, yes. pretty awesome, right?
A swamp cooler that can handle saltwater. Not as easy a task as using freshwater.
Not genius at all... poorly copied of things already in existence.
- Sundrop Farms in Australia got operational with a 20 ha. seawater cooled semi-closed greenhouse... with indeed the same pads as used here (the horticultural industry calls them pads and not corrugated cardboard walls, LMFAO on that one).
- Pad&Fan greenhouses have been in existence for decades... Nothing new on that part.
- Using seawater is just not recommend as... they do salt up and that does create issues, regardless of what they said in their article.
So, nothing new.

What happens to the card board walls after they salt up? How often do they need to be replaced? How does this affect the cost? How do you dispose of the salty card board material in a closed cycle way?
Exactly my question. They made it sound so simple but the cardboard would salt up so quick!
Secondly, I remember loving in saudi and using desert coolers to cool our houses. They work great in dry hot climates but in humid coastal areas where the salt water would be most available, those coolers didn't work at all.
It would make more sense if they use the sun to distill sea water to irrigate crops.
@@muzairanwar Plus, heating water produces steam, which can also be used to power turbines, which means more energy output.

Something positive and so useful for masses of people on the planet, why isn’t this talked about to the same level as the doom and gloom we get every day ?
It doesn´t get as many clicks/views.
why isn’t this talked about to the same level as the doom and gloom we get every day ?
Gloom and doom (aka blood ad guts) has been the leading news of the last several millennia, since people associated in large communities. Most media now is profit oriented, whether that is print news or on the internet. Information is out there, but the "news" doesn't seen information pushing viewing. Gloom and doom does.
Possibly because the "cool house" benefit isn't 10-100x less water (for the whole system, not just the crop- cooling paper walls also use water and probably can't run on saltwater) as they claim, and it doesn't make desalination economically viable. Or it's being tested.
Still, the 10-100x claim seems too good to be true.
Honestly love this, I truly hope this can change the world!
It will change the world all right but not for the better.
This is Nobel Prize material, right here. I hope this system is widely adopted and used.
Its not because its not worth it.
1, ongoing costs = carboard replacement, water pumps maintenance (salt water degrades metals faster then fresh).
2, set up costs one off so not really worth mentioning, but plastics for cover, cost of equipment.
3, skilled farmers, its a country that does not have a lot of farmers experienced with the crops it could grow, I imagine training incentives would be needed.
4, lack of control, the system is almost enterally dependent on the outside.
5, does not reduce the cost of growing crops, only makes it possible to grow eg a lettuce grown overseas will cost 30 cents to grow it will still cost that 30 cents plus this set up on top of that. I would argue it would cost more then that due to lack of resources for farming.
I view it like oil extraction, there are processes that are really expensive but because they are not economical viable they are not off the ground.
Real world its got to make someone money to be worth doing, this does not do that so investment is not going to happen.
@@generalharness8266

Clearly just as with conventional greenhouses there will be calculations for what kinds of crops are most appropriate to be grown. Smaller high yeild crops for the area/water usage.
3: If you're going to pretend 1000s of these farms will appear instantaneously, can you also pretend the farmers will be trained instantaneously? SMH
4: Sounds like every other farm in existence.
It probably isn't the panacea some hope for(nothing is), but a good potential option. Not sure what your alternative is, starvation? Depending on the overfished ocean?(ie. starvation) Waiting for benevolent countries to save them in perpetuity?(ie. starvation)
I didn't even think about usint seawater to humidify the crops... But this guy showed us the way to combine evaporator and seawater to cool down the crops, and they might even change the climate somewhere in the future!
And sea salt can be taken from the evaporators as well!
@@victorrain "can"... what for do you think your brain is? Using that thing as intended doesn't hurt!
I've been working on something similar using solar desalination to produce salt while providing water to my plants. Good to see this. I started from the perspective of resources at hand and potential salable commodities. The value of the recovered salt offsets the water production . Before going solar it cost me 72 cents a kilo for the salt and this included the waste by product of 15 liters of free water
To all the negative salty people here ( pun intended ). The salt would build up yes. The next step would be to convert that into sellable salt I would think. 2nd this is the entire point of research and development. Research means to use the salt productively and perhaps use those funds to pay for cost and maintenance. Develop better cardboard to have less frequent need to replace.
Dont think, your thinking hasnt got you anywhere. Either you know or you dont know. Wishing something is true or real isnt the same as it being true or real.

This is what we need to spend money on. Not countless useless social programs that tend to drain resources while allowing them to be abused. Science can literally lead humanity to no longer take so much from our planet while giving back nothing
This solution has been available for many years, I wonder why it is now that it is gaining traction. This is true for the US and other country with large deserts.
Love the idea!
Use of solar powered pumps to pump the seawater inland would green the project further.
The. Seawater could be distilled via the desert heat to produce fresh water for irrigation and salt to sell.
Brilliant!
*Wonderful invention.* We need this to feed the world.
We can be more happy as a culture, if have enough food and water for at least basic life.
Been using the gravity fed water closed loop system and fan cooling in greenhouses for cooling and humidity control since the 1970's that I know of. These cool houses were old then. Probably built in the 1940's. Used to cool plants before flowering to get them to have larger buds and then move them to hot houses to force the bloom all at once for sale. The plants would gradually bloom without this process. The full blooms at once obtained a better market value. The system I worked with used 4' x 4' vertical filters like green scrubber pads with larger openings. They were easily cleaned and reused.
Nice way of doing things. It would work really well if the salt didn't contaminate the soil from using a big cheap swampcooler.
It might be better to recycle glass and aluminum into passive desalination panels, and reform plastics into drip irrigation pipe. It takes a lot more land, but in desert areas thats ok.
Also, I suggest doing permaculture swales, with drip irrigation for trees, and only using plants with light green leaf coloration to reduce temperature in the local climate. Things like date palms, pistachios, even pecans, almonds, and edible cactai, and hardy soil fixing cover crops like barley.
Barley straw would be a great starter chop and drop, to add soil carbon and water preservation.
Eventually a fast growing chop and drop plant like moringa, or sorgum-sudan grass, or lemongrass, or perhaps a local desert plant, or something like mesquite, would need to be used to feed the soil. Even cassava could be used for a chop and drop soil protection.
The best idea though is barley. Harvest the tops, then use a roller to flatten it down, and resow for the next season with a roller seeder. After a few season there will be a dense vegetation mat with plenty of nutrient for tree varieties. Continue replanting barley as the trees grow, and when the trees are big, plant something else that's fire safe, like beans, or peanuts, or continue with barley.
Vegetation attracts and holds water, if the right plants are used.
Just don't let any animals graze after harvest for a few years. 5 or 10 or so, and when and if you do, practice migration pattern grazing.
Great ideas. Thanks, man. You just wrote a paper on the subject. Can I incorporate that into my work?
Ya, sure, the best ideas are borrowed or stolen.
What a great Idea. In Holland Duch farmers in Freezland have developed crops which can be irrigated with dilute salt water 50/50. Some can even be irrigted with salt water alone apparently. All done by years of natural selection for salt tolerance.Good crops of potatoes are now being grown on land in Pakistan formally too salty to support normal plants.

For once, and really once, I think technology has a real interest in agriculture and food sovereignty. This kind of technology should be used to recreate water self-sufficient micro-zones as oasis. The greenhouse would be a tool to build a cultivated ecosystem ALSO outside of the plastics. With desert adapted trees who can create micro-climate, making a cooler atmosphere above their boughs, build healthy soil with organic matte rproduced, and making agriculture possible over time.
this great development it will help many parts of the world to do more in food shortages , and thank you very for the invention and your interest to support my country Somaliland with this kind of technology, we welcome you and will help you what ever support we can do for this kind of projects .

In the Sahara Desert there are no clouds because no air vapor turns into clouds but I found a strange appearance in the middle of the Sahara Desert in the Niger region there is a small collection of clouds passing in the middle of the Sahara Desert of the Niger region and then watched closely there is a dense forest under the clouds Located in the estuary of Mount Air Mountaint which often gets annual light rain and the water is sponsored in a puddle in the valley until it turns into a forest.
The Sahara Desert is making an artificial forest in a border valley (ridge) as wide as 20 km long and repairing rocky hills in the middle of the Sahara Desert. When it rains on the mainland, it is an ancient river upstream, the air will automatically return to the ancient river which dried up thousands of years ago, shifting the earth's axis

Is the water that's stored potable, or able to be made potable? I could imagine a solar powered OSEC unit being used to convert brine to sodium hypochlorite which can be used to treat any excess water for potable use.
You could also install other solar thermal applications alongside to increase yield of water when conditions allow.
Hi David! Good thoughts and thanks for asking. The folks at Seawater Greenhouse actually elaborated on this a bit in some of the other comments. To quote from their responses to Rachel Bell:
"Evaporating seawater to create fresh water vapour in our greenhouses cools and humidifies the air, reducing irrigation requirement around 10 times. We produce around 2-4 cubic meters of fresh water per day to service our farm in Somaliland..."
"We use the brine to produce marketable, culinary grade sea salt. So no water is pumped back to the ocean!"
Hope this is informative and thanks so much for watching!
Brilliant... not only that the water cools the air, but also humidifies it by evaporation, and this humidity is also being absorbed by the plants, needing less watering...
Fascinating!
Even tho Africa is the birth of civilization, their location and weather has held them back throughout humanity. Rough deal.
Yeah. Civilization may be birthed in Africa, but it developed and florished in more suitable parts of the world.
That is brilliant!
Interesting, yet leaves a lot of questions… some:
- is the same salt water constantly recirculated ?
- spent water goes where ?
- how long until the evaporator wall gets clogged and needs replacing ?
Etc.
I recall reading about water irrigation schemes in Australia using artesian wells and pumped ground water to irrigate crops. The water had mineral salts in it which eventually accumulated in the soils due to evaporation and ruined the soils eventually. A similar sustainability problem could exist in this scheme. Regarding the present security situation in Somalia, how do you prevent warlords and their gangs from destroying these greenhouses?

Your idea needs far more space than the system in the video.
Their trick is to produce extremely humid air inside the greenhouse, so the plants need only very little fresh water.
This is pretty revolutionary.
Imagine the possibilities if aid agencies funded these kinds of projects instead of just handing out food! They may eventually become redundant.

Interesting idea. How do they dispose left over saline water?
Good question!
"Nutrients harvested from the brine are pumped back into the irrigation system to fertilize the crops, and the rest of the salt is made into gourmet salt crystals that Seawater Greenhouse Ltd. sells."

Excellent way to cool and add moisture needed for temperate plants to survive in hot dry climates. Shade houses are used in our area with wall of evaporative media, wall of fans on other end. More complex but more amazing Sahara Forest project is enclosed with fan wall opposite evaporation with CONDENSER pipes to extract distilled water from saturated air leaving greenhouse. Cool moist exhaust air from greenhouse allows many other plants grown outside to do far better than in hot dry ambient air.

How long does that cardboard last?
Great question!
From the Science and Development Manager of the Sahara Forest Project, another one Seawater Greenhouse is helping build:
"The cardboard evaporative pads will need to be changed out eventually, but not often. In the early Seawater Greenhouse built in Oman, the original pads were still working after more than two years. When they do require replacement, the retired pads will be re-used - potentially as building materials."
More info: blogs.ei.columbia.edu/2011/02/18/seawater-greenhouses-produce-tomatoes-in-the-desert/
Hello! The pads last up to 7 years or more. Calcium build up on the cardboard actually helps to increase the lifespan of the material by giving it structure and rigidity.
When you consider the canaria islands, big holiday destination for Europeans, get the majority of their water from desalination it shows that desalination plants can produce enormous amounts of water. A huge desalination plant near the sea and a few hundred miles of pipe and you can create lakes inland in desert regions which in turn, once filled, can be used to green the area
have you ever heard of a electricity bill?
desalination as of now uses enormous amount of electricity made by fossile fuel
Seems like they’d still have any issue with salt buildup and erosion of the cardboard walls.
Per an article in The Engineer (www.theengineer.co.uk/greenhouse-uses-seawater-to-grow-crops-in-arid-places/), the cardboard is designed so that “Salt and other minerals collect in the base of the wall where they can be harvested and sold.” So the answer appears to be that the cardboard doesn’t need to be replaced.
It looks a lot like The Sahara Forest Project! Great concept👏🏻
Im wondering how much water theyre actually having to use in the place(s) that theyve implented this. Is there data for that? Guess ill have to investigate
Good question: there's some information here: blogs.ei.columbia.edu/2011/02/18/seawater-greenhouses-produce-tomatoes-in-the-desert/
"The Sahara Forest Project will use water from the Red Sea in seawater greenhouses to produce fresh water for the crops and grow algae in open ponds for fuel and food. The project will also grow halophytes, plants tolerant of salty conditions, that have potential to be an energy crop. Because each 10,000 square meters of seawater greenhouse evaporates 50 tons of water daily, the greenhouse will help restore vegetation on the surrounding arid land through ventilating the “lost” humidity to create a cooler and more humid micro-climate downwind of the greenhouse. The “lost” humidity will also increase the chance for precipitation in the area. The algae, crops and other plants will sequester carbon dioxide from the air. Extra fresh water produced by the seawater greenhouse will be heated by a concentrated solar power plant (CSP), generating steam that will turn a turbine to produce electricity. The CSP’s excess heat will be used to desalinate seawater for drinking water. A single Sahara Forest Project facility with 50 MW of concentrated solar power and 50 hectares of seawater greenhouses would produce 34,000 tons of produce, employ over 800 people, export 155 GWh of electricity and sequester more than 1,500 tons of CO2 each year. If the demonstration project is successful, Aqaba will provide 200 hectares for a larger scale facility."
But you pump out the water with higher salt content back to the ocean.

Not to mention the fact that marketable, culinary grade sea salt can also be produced this way.
the evaporators will become clogged with the remaining salt, after the water evaporates.
salt is water soluble, so it would remix with the water, after enough time if the salt is able to built up to silly levels it can be scraped off and sold or used.
@@thegentilehunter Salt isn't water soluble when the water is already saturated with salt
@@stickmanbrains it's a good thing sea water isn't completely saturated with salt.

Hi Julien. Concentrated brine is collected and harvested to produce sea salt that is sold to market. Some calcium can build up on the cardboard, which helps give the wall strength and lengthen the life of the material. Every once in a while the calcium must be dissolved.
In the Philippines , many small Islands have trees and coconuts. They are naturally mainland plants but how are they getting the regular water when they are practically surrounded with salty sea water. those living plants must have evolved to be able to filter salty water.
There's so much of the story missing that it wreaks of scam...
It's no scam, I saw a very small scale trail of this method in Cyprus in the 1990s - it works brilliantly. Then they weren't usinv solar power for the pumps, just an old 2 stroke deisel(which were still widely used then to pump water from boreholes). There it was set up close to the beach and make use of the predictable onshore winds.

Lol nice but maybe take the trolling to a different video. Most people here won't get that you're joking
please I pray to god that you're being a troll
I live less than 5 miles from the Great Salt Lake. One issue I imagine here is that running seawater continuously through a cardboard "swamp cooler filter" will clog that filter with salt in a relatively short period of time as the water evaporates from it, necessitating the replacement of the filter. Is that this corporation's business model -- to sell a lot of filters? Or is there some component in this system that will desalinize the water before running it through the filter? Because desalinization of water at the rate I'm imagining for a system this large may also tend to be pricey.
They replied above the cardboard lasts 7 years.
The cardboard I not a FILTER! It’s merely a medium to distribute the water to a large surface area for it to evaporate into the air.
Actually, this would work for desalination as well. Most of the work of desalination is getting the water to evaporate. You can then cool the wet air to condense the pure water out of the air. This method uses a large surface area to do this and the ambient temperature, instead of a lot of heat to boil the water.
The question remains what happens to the salt and wet air? Is the salt collected? Does the wet air stay in the ‘cool house, or does it get exhausted. If you did this of a large scale, could you humidify a desert? What would that accomplish?
The answer to both fresh water shortage and reliable crop management, we pray that this kind of tech is applied and implemented as much as defence related work. When everybody has food, no need for wars. 🤔
As an Islander who import almost all pur food. Our land is dry, coraly, and salty almost accidic. This would be amazing! To reduce the temperature and amount of water needed.
400M USD is a drop in the bucket. The problem with many parts of Africa is that there are too many people who are bent on destroying anything that benefits someone they don't like, so even if the West decided to give this facility to Somaliland, some crazy guy is almost guaranteed to destroy it sooner or later. It is not without reason Somaliland looks the way it does.
And just to set the record straight, I have nothing but sympathy for those who live under these awful circumstances. We would just need to find a solution that could ensure that won't happen.
what happens to the salts accumulated in those cardboard walls? how often does it need to be cleaned or replaced?
You don't have to accumulate any salt to make this work. Sea water contains on average about 3.5% salt, which gives you a lot of evaporation until your solution is saturated (~26%). So you have to replace the water before it reaches that salt concentration, then salt built up won't be a major issue.
I’m all in and I love this idea. I wonder if non-GMO seeds and/or even the seeds of indigenous wild herbs and edible plants (food) can be planted using this method?
Fantastic, California and Australia would find this useful .....
I like the idea that possibly the cardboard could be made from recycled paper as well as recycling the cardboard used. Add to that packaging and selling the mineral byproducts removed from the water and the whole idea is pretty awesome. I hope further investment will be made to bring this technology to financial sustainability.
I think the best bet is to use the incoming tide to fill a still. Focus the sun on the still via mirrors. Have the steam exit high into a cooling condenser and let the water flow by gravity to where it’s needed. No moving parts.
Any thing that involves sea water in this manner will cause it to produce heavy brine. Most dump it right back into the ocean. Over time the area becomes toxic and almost all sea life near the shore dies. This has happened in many areas where there are desalination plants. This is the main problem with using sea water in any process that condenses or evaporates.
God given resources sunlight sea water land and human brain put to good use to benefit all👍
Good idea! I LOVE it.

luscious and temperate -- just like me!
True costless desalination : Build a huge greenhouse dome by the sea water, pour in water to get heated under the sun, collection evaporation for clean water, collect salt once dry. Put geothermal heating pipes as well. Initial cost: about the price of a green house. Maintenance costs: almost nothing, just cleaning could be paid selling the salt alone.
Fantastic... sign me in !!!!
great video. you could package up container loads of the salt crystals as a by product and sell them to first world countries
Another issue is these people in third world countries where they can't even sustain themselves or grow food are having too many children.
One problem is not addressed, the salt from the seawater.
Another very promising video, a solar dome, uses a greenhouse dome and tunnel to warm and condense seawater. It's an ecological variant of typical desalination plants that use fossil fuel.
But either way, every two liters of seawater produce 1 liter of fresh water and 1 liter of brine. You can probably dump it back into the sea, but not close to the water intake point (or the water will get increasingly saltier). Also dumping the brine creates such high levels of salt that it's harmful for the local eco system.
If you can somehow disperse the brine or get it to a fast flowing current that might be solved. But transport of bulk volumes is costly. Probably two separate very long green house tunnels, one to draw seawater, one to transport the brine can solve the problem. Maybe not concentrate the brine too much, and just draw a fraction of a huge flow of seawater could prevent ecological impact.
I think if that problem is solved, this fresh water produced here can use the technology in this video for cooling and providing humidity.

Love people creating solutions instead of problems
At the beginning I thought the greenhouse was to evaporate the water, taking it apart from the salt and then used to irrigation.
This looks pretty cool.
One material that will be very important for things like this is graphene.
Fantastic breakthrough .. Now also address the REAL problem of overpopulation. Slow down the breeding in Africa.
Ingenious.
Great idea. I wonder what the cost would be like to repair and maintain this would be? I bet once they are producing enough it would pay for itself to be maintained. Is the soil fertile enough to grow a good crop?
Heard of growing crops in an underwater greenhouse, situated near the surface of a warm, shallow sea. It would take the form of a waterproof dome. Evaporation would condense onto the glass, to be channelled to the plants. More hi-tech than this fine idea. Have not heard of it's application.
yep cause contructing that is fucking expensive...
Wow.
