Water is in short supply in much of the world - but what if we use seawater? It's been a dream for many years, but now technology is making it possible. This new seawater greenhouse uses a clever cardboard design to distill fresh water from salt water cheaply and efficiently. It's helping grow crops in Somaliland, and could help stop the water crisis in Africa and other parts of the world that are susceptible to drought. The founder of Seawater Greenhouse, Charlie Paton, explains how unlike traditional greenhouses - which are hothouses - this one is a "cool house" that is ideal for growing temperate crops in deserts or other hot, arid regions.
What do you think? Will this succeed at turning desert into farmland? What other projects have caught your eye? Let us know in the comments and subscribe for new videos every week.

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.

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.

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.

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

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.

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.

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.

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.

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

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!

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.

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."

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.

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: 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 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.

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.

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.
