This Tower Turns Ocean Fog Into FRESH Drinking Water!

Fresh water is the cornerstone of all life, and it always feels like we either have too much or too little. And while desalination has grown in popularity, it is very energy intensive to separate the salt from ocean water. But a novel idea is emerging that harnesses the water vapor right above our oceans and transports it back to land. It promises to be the lower cost lower energy alternative to desalination, but will it actually work? How much water can it realistically produce, and might this be a key solution to our water challenges in the future? Let's find out! Limitless Fresh Water Lies Right OVER The Ocean - Without Desalination!

This basically what your home A/C or dehumidifier does . I connected a bucket to my condensate drain (my dehumidifier has its own built in container) and pour the water into a 45 gallon trash can. When it gets full, I have a small pump and water my grass with it. There YouTube videos out there with other's doing this. That is what I do with the water but you may have other uses.

As an retired environmental engineer I was also excited to hear about this idea. There are numerous ocean locations in hot areas that have deep cold water relatively close to shore. Monterey Bay for instance. Using a thermal-cline with a closed loop cycle containing a freon base fluid that reachs from the depths to the surface could provide the force to drive a pump to send the water to shore. Routing the humid air into pipes using the cold from the depths would also provide the cooler temperatures necessary to condense the water.

This should be labeled science fiction. The physical plant of these structures is simply enormous. Building only one of them would be considered a mega-project. Building multiple would be a literal impossibility. The structures are 200 meters wide, which is essentially the height of the golden gate bridge, but in width, not to mention the structure also rises 100 meters above the ocean, ignoring the size of the structure under the water. The environmental impact would be catastrophic. The size of the structures dimensions are equal to a New York City block, meaning the entire rectangular block, replete with multiple sky skyscrapers. 10 city blocks rising, hundreds of meters off the ocean floor are going to be built off the coast of major cities? This idea is sheer maddness. I hope the scientific paper detailing this project was the work of graduate students asked to dream up impractical engineering projects to solve fresh water availability and not a serious design.

I work in HVAC design, so I know all about taking water out of the air. I've wondered if we'd ever get good moisture farming tech, kind you see in Star Wars (Luke's uncle was a moisture farmer). The concept of taking it from the ocean's surface is fascinating. I don't know about their plan exactly, but we could probably engineer something pretty easily. Awesome video man!

Since this depends on relative humidity and vapor pressure, it will work markedly better in warmer zones. In addition, there'll also be a large amount of microcrystalline salt that gets captured as saline vapor deposits. Normally most of this is recaptured in the ocean. It's why ocean side steel structures rust so quickly. It's a pretty massive problem. The closer the capture point is to the water the higher the salt content also.

I think this could work in Namibia. They have a unique geography where they get constant fog but no rainfall and a huge desert. Most coastal places with humidity get plenty of rainfall.

[jonjohns]

I wouldn't do a tower per say, I would instead repurpose an Oil tanker sized ship. Have it go out to sea, collect the water then bring it back and pump it into holding tanks. This improves collection because you can send the ship to places where conditions are ideal and you can use deep (cold) water pumped up to the surface to cool the condenser. Plus you wouldn't have any visual pollution of large towers just off shore blocking the view.

This is the most exciting and practical water solving idea I have heard yet to date. I think you're right, they have really hit on something special. As soon as I heard it, it's like a light bulb went off in my head, of course, all that water is just sitting there in the air above the ocean water. It makes so much sense and sounds like it could be easily done. Kudos to you for reporting this. Nice work!!

[JorgeLausell]

I drew this out a few ways when I was in grade school. Teacher thought it was cool.

I've many such.

Worked on how to get these sorts of projects done, generally.

Here's another: Water use in a different way, in the desserts. Use boring tunneling to make the widest & longest you can in 9 months, as a reservoir. On the land above that dig contour trenches, back filling with composted soil & shaped into swales. Shape them to work to slow down & absorb as much water runoff as possible, work on new geopolymers. Include atmospheric water harvesting features. Design to pipe excess into the boring tunnel-reservoir. Site these densely enough to capture sufficient stormwater runoff to provide slow, multi decade, reclamation of depleted lands.

Elevator pitch version.

They've been doing this on a small scale along the Namibian and South African coast, these areas have sea mist in the mornings almost all year, they put up mist nets and collect the water in chanals along the bottom of the nets, produces a surprising amount of water,

I have been working on AWC for a decade. You do not need any cooling towers. The ocean water at depth is cool enough to cause condensation. You just need to pump it up. And you don't need big pumps to do this. You just need an electric current to cause electrolysis which changes the density of the water, causing it to rise (like an air pump)

I had this idea years ago. The ocean vapour towers could be enhanced by making them transparent like greenhouses. A black slab metal or rock occasionally beneath the surface due to wave action should aide evaporative throughput. Sweet.

[tonydeveyra]

My idea for optimizing AWG on a home scale:
Build a greenhouse that's attached to your house, preferably on the south/Sunward side. Water the plants within with your gray water. The greenhouse will naturally be very hot and humid within. Run your AWG in there. The plants will transpire your greywater and the AWG will work at top efficiency most days as it will be near 95% RH in there constantly.

Rick, knowing this is long winded I submit the following: Some years ago mechincal engineers installed an adequate amount of air-conditioning to a gymnasium as was specified by the architect but because it was a "fresh air intake only" the humidity in the area was just too much for the system's evaporator coils to remove and this lead to a very uncomfortable cool but sticky environment inside the gym. So what they came up with was placing two additional coils (one after & one prior) to the refrigerative evaporator coil with both coils connected only by a simple water loop. As the aft coil received the refrigerated air cooling it (and then passing through it so as to cool the building) that after coil would cool down along with its water loop being pumped back into the prior water coil. Now because of that the outside air entering was pre cooled removing more humidity, the evaporator coil (now 2nd of the three) too would remove even more humidity and lastly the third "after coil" likewise would remove the majority remaining humidity as well.

Other than the additional coils, the water they contained in a closed loop and the small electric pumps no additional utility cost in cooling ever happens and yes, a measured normal of 80+% humidity entering the gym was reduced to a modest 30-35% afterwards. And this says nothing about the condensation captured.

My point, if this were used in costal high humidity area's and you were going to air condition them anyway, why not make water while you're doing it and further cool your building down while doing it. Yes, you read my statement correctly.

people move to a desert, then say we are running out of water. there is water everywhere. we are never running out.

The average Southern California home flushes about 15 gallons (this is a very conservative number) of clean fresh water down the sewer every day during the summer while running a home air conditioner. The energy is already spent on the A/C cooling, yet the perfectly clean water is flushed down the sewer.

(Well, not at my house. I have a large home with two A/C systems and all my condensate water is diverted and stored to water my gardens and grove. The A/C is powered by ground based solar)

[CorwinPatrick]

You should do a deep dive into water consumption in California (Industrial, Agricultural, and Municipal) in relation to the natural capacity to replace it. I suspect you'll find that the "Mega-Drought" is simply over-consumption. California (well, everyone, actually) is ignoring the actual problem by blaming the weather. California also has a 100+ year history of just draining lakes and rivers dry.

[feuby]

This is awesome... And if you use pipelines underwater (like for petroleum, but for gas) you could even get to some water almost free, because on ocean bottom the water is cooler. Thus, this may help cool the water with no energy cost at all, and we could cool it further to extract more water. Maybe that would even work just with a pipe going under water if water is shallow enought, then you'd just have to use giant fans, no compressor at all. Easily replaceable, but you'd probably get less water overall. And warm up a bit the ocean bottom, but meh, that warm water will rise, then evaporate again, so...

If you want a really effective way of harvesting drinking water from the oceans, you would want to build a large solar-updraft tower, either as a floating device or on land near coastal area and fill the surface beneath the canapé with sea water. Dimensions are 5km diameter canapé and 1km large solar tower using strong and lightweight materials. It harvests energy from the updraft humid air, and condensers in the tower can harvest drinking water. Plus you can collect any rainfall on the 5km diamater structure and store it in tanks.
You could also built them on land near a mountain range that is a barrier for rainfall, and built the tower alongside of the slope of the mountain range, and fill the surface under the canapé with sea water (so it has to be built close to the ocean). Some of the humid air will escape and will increase rainfall in the area that normally is part of a rainshadow.

We like to experiment with atmospheric water capture and recycling on our homestead in the Ozarks. We have experienced a drought this year, but the passive water capture from condensation has made a big difference. Rock berms that collect morning condensation is the main system in our gardens.

So, I've thought about something more along the lines of relatively passive technology for capturing water as condensation from the ocean. Instead of building towers I envision water pumped into open troughs with glass or plexiglass panels positioned to collect condensation and divert it directly to fields for irrigation or to a water capture system. But for huge agricultural fields that may get in the way of equally huge farm machinery. A better idea is to move food production to smaller scale urban sites that use grey water condensation. Small scale urban food production should lessen the energy inputs required, especially for refrigeration and transportation. For instance, I grow all my salad fixings indoors in an area the size of a large refrigerator. Fresh food all year and no trips to the grocery store is reason enough to start bringing back residential gardening.
