Just use the old camper's trick. Fill a large can with salt or dirty water. Put a small can inside the large can on a support so it doesn't float and tip over. Cover the whole thing with plastic, and put a pebble on the plastic cover so it forms an inverted cone. The small can will slowly fill with pure "distilled" water through evaporation. This works best if it's hot. Now scale this mechanism up in size.

easy way to reduce water waste is having 3 water systems at home, fresh water for drinking and shower, sewage obviously, and finally a recycled water from the wasted water treatment plant to be used on the toilets and some gardening aplicantions, since that recycled water cannot be consumed due the chemicals used on cleaning and so on, instead droping it bck on the rivers and ocean it should be taken back home to the toilet again, it may not look much but you must see the big picture here, millions of people everyday wasting 5 gallons of water everytime they flush in just one day that would fill more than one olympic pool across an entire year you can imagine, every little bit counts, special on desert areas and countrys if we can extend that water for a little bit more than all investment is worth it

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.

You still have to pay the cost to phase change water, that is the minimum energy cost of this kind of system which the energy cost to evaporate water at 99.9C is the same energy cost to get it from 0.1C to 99.9C which is enough energy in the same wait of copper to melt it, and doing the reverse means you have to remove that much energy. This is already assuming 100% humidity and only knocking it down a little. Yes you could dump that heat into the sea by running the pipes down low, but then you are going to reduce heat rejection in that local area destroying habitats if you are pulling out meaningful amounts of water, because that volume of water that evaporated off carried enough energy to raise the same amount of water to 99.9C form 0.1C so if you pull out 500 million gallons from humid air you are dumping enough heat to raise 50 billion gallons by 1C. Now on a global scale that isn't going to effect things, but on a local scale that certainly is which is the same issue you have with brine discharge, brine discharge isn't a problem if it's distributed evenly over a wide area, so you're exchanging one type of pollution for another. Now if we are going to use refrigeration there is some good news because heat pumps can move upto 6 times more thermal energy than the electrical energy you put in with ideal conditions so you can reduce the energy needs down to heating water down to 16.7% that is assuming ideal conditions however and I am goanna guess that reverse osmosis is at worst on the same level of power consumption, but probably significantly less. I suppose you could make it so that your only using the sea to remove some of the heat to reduce the energy consumption maybe even only use the sea to dump heat during peek energy demand or low energy supply which would make it work well with renewable, but the extra cost of having two systems to bring it ashore would increase the cost of the total system fairly significantly.

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.

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.

So, so cool. Thank you for your work!!! Always inspiring and hopeful.

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)

Google must be reading my mind, I've been thinking of this idea for a lil bit now, but slightly different. My take on the idea was to use newly developed radiative cooling paints to cool down a wide air channel, then reduce the temp even further with normal condensers. Above 75% RHI you don't even need the condensers to start yielding water as the equilibrium is 4-5C below ambient. (And I think you can push the equilibrium further given the right layering, IR absorbent undercoat, and topology) You could push air pretty fast through it and still keep it not too long if I did the math right. a 300x4m system at 25mph could yield 12 gallons per second iirc

We live in middle TN, one of the most humid (and rainiest) areas in the nation. Water bills are through the roof - $200-$300 in the summer and I have an enormous landscaping / garden. Due to the elongation of seasons many farmers are attempting double crops (plant April / end of July). Our A/C drains water from the air into a hose. Last summer I guided the hose into a 3 3 1/2 gallon bucket. It rapidly filled and I repeated twice before I called it quits. This year I attached a series of hoses that open or close. I water tomatoes, melons, peppers, flowers and herbs for next to nothing. The amount of water that only one units removes is just amazing. This project screams "venture capital" which is by far the fastest and easiest way of bringing it to the market.

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...

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.

Worked in a lot of powerhouses. The old boilers had preheaters that if you reversed the system would work as condensers. They were basically giant tanks with thousands of small tubes filled with water. Your sea air could be ducted into the body of tank and if you filled the tubes with cold water that you had chilled by geo thermal means you would get condensation. Then only real power you need is for pumps and your fans. Depending on how much water you are causing to condense and the drop to the pumps. You could even put those horizontal positioned water turbine over the outlet holes of the water to help with power demand. Like videos keep it up

This actually has the same net salination effect as releasing brine into the ocean, just in a more diffuse way (so it is still better). That's because decreasing the vapor pressure (which is what you are doing by pulling water out of the air) is essentially the same as desalination. To explain just a bit further... water evaporates slower when the air above it is already full of water, more water = slower evaporation so less water = faster evaporation, and that water is evaporating from the salty ocean, ie evaporative desalination. These seem like a much better way of desalinating water, but that is still in essence what it's doing, and the resultant is a saltier ocean (which is a growing issue). Projects like these are great to meet growing water demand, but they don't solve the sustainability issue. In the end, what we need most is to be much more efficient with our use of water, because just like climate change, it's not a problem that will just naturally reverse itself.

Even with that aside, the effects of increasing salt concentration is localized to the areas the desalination occurs, so it still has an environmental impact on local ecosystems. Even THAT aside, the ocean AS A WHOLE is becoming saltier as we mine salt from below the earth (and spread it all over our roads and use it in various chemical processes), and it makes its way into the water supply, although this is counterbalanced by the (objectively bad) melting of freshwater reservoirs of ice.

I think I see what you're saying, but this is taking advantage of a process that already naturally occurs, whereas traditional desal pumps highly concentrated brine back into the sea. It's not that this is inherently bad, it's just that local ecosystems aren't equipped to handle it. This process is tapping into a cycle that is already taking place, and because of that, local ocean ecosystems are much more likely to adjust to it or accommodate the impact of it. One way or the other, water generation is going to be a primary solution to growing water demand. Humans *could* conserve their way out of this, but if any other viable option (like this seemingly is) is available, humans are going to take it. I know I will.

Completely agree on that, this will be much better than water desalination. This needs to be built, at least in a smaller scale to see if it really works.

With offshore wind, they're already laying down miles of cable to connect everything with the mainland... might as well lay down some water pipes at the same time to move all this fresh water to the people who need it.

As a Perth resident, I would love to see something like this here. It would be great if we could allow our dams to fill and be used for recreational activities instead of being off limits. And 4 to provide all off the water requirements? No need to rely on groundwater and desalination

A beautiful machine… My chanting/meditation/prayer is for the success of the innovative humans offering real solutions to our problems. Bless them and the love they offer us.

This is amazing, so simple

If you add dark-painted floating metal mesh, then evaporation rates will increase, so if you place those near the towers, then you will get more evaporation and higher air humidity in the air you're using to get water. If you add cheap imperfect metal mirrors to allow the pipes to cool down, then simply going from the higher air pressure inside the pipes to the lower air pressure inside the water silo, will get at least some of the water to condense, and you can also get dry cool air as a byproduct, in the hot humid areas where it's most valuable, like a city-wide central AC unit delivering to places which pay for it.

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.

Combine this with wind generators and store the water to have it collected by a purpose built (small) tanker ship, transport it to a facility onshore to be put into the water system serving a city. This could benefit a rural area by reducing the water taken from the rural area to service the city.

So far, this is one of the best ideas I've seen for water harvesting in saltwater. 😄 12:00 It's quite nice, but the water then goes to others where it would normally rain. Even this small amount can already cause rain to fail in low-rainfall regions with poor people. So there should already be a simulation that times the changes over a decade. Rain is not about the total amount, but about the amount of precipitation per day. Reminds me a bit of the Aswan Dam, even if the comparison is lame.

It's much more complicated than that, humidity in the air most of the time in most places will never become rain so it's not taking away anything. And 10 miles away the humidity on the ocean will be completely unaffected. Additionally, if the water is used to grow crops in a dry or drought stricken area that will actually actually increase the humidity and the likelihood of rain because of the transpiration from the plants

BRILLIANT!

I REALLY appreciate how you can explain the the tech, the benefits and most importantly $$ to people to weigh in their thoughts. Unfortunately, $$ takes a higher priority in some but it explains why that is and the benefits. Don't build cheap.

This is such an interesting idea. I imagine there are some things to be worked out but none of them look to be insurmountable/cost prohibitive. This concept seems like a great candidate for funding a few different groups to develop and test some different versions as test pilot projects (powered by onsite solar vs wind vs shore power source, etc) Then see which work best and iterate through resolving the issues to find to most robust solution. Since like 70pct of the population is with 100 miles of the ocean these could be a good additional source of fresh water. One thing I also think of is in places like California where any water they use at the coastal cities is competing with water needed upstream inland for agriculture and there often isn't enough for both. If they could supplement nonagricultrual water needs near the coast with these it would relieve pressure on the other water sources needed for agriculture inland...after all we also need food :-)

I use dehumidifiers in my Scottish home, and other than using it for watering non-edible garden plants and equally non-edible house plants - I tip the whole lot away. Unfortunately, with devices like HVACs and dehumidifiers, because the manufacturers are under 'no obligation' to create these machines for the use of collecting 'drinkable' water, they allow that collected water to run over surfaces containing copper, aluminium, a variety of plastics (including carcinogenic ones), and even lead. In addition to these materials, there's also the issue of micro-organisms which commonly collect in the pipework, tanks (dehumidifiers) and trays (HVAC's). Legionnaire's Disease is an especially infamous micro-organism that instantly springs to mind. As my husband knows a retired engineer who worked with HVACs, the strong probability of dangerous micro-organisms was his warning to us when we enquired about the safety of using collected water. I checked sites dedicated to issues concerning HVAC's and they definitely advise 'against' using the water for edible plants, giving to pets, using it for human consumption. It is, essentially, polluted. Because I was still rather curious about the quality of water from a dehumidifier, I did once try the collected water from a new machine for a pot of tea. The taste was amazing, like it was a completely different drink. There isn't a water filter I've ever used that has come close to producing water that makes tea taste so good. However, my experiment was a one-off and I wouldn't chance it again, no matter how thoroughly I 'try' to clean the machine.

On an ocean vessel or abandoned oil platform small amounts of sea water enclosed in a transparent pressure cooker with sunlight concentrated onto the pressure cooker will vaporize the sea water at a 160 degrees or less, the salt is then scrapped off and stored for pickup and the fresh water is also stored for pick up. Since the water and salt is all removed, there's no harm to the surrounding Ocean and wildlife.

When seawater freezes, you get freshwater ice. You can put seawater in a hanging bucket and collect the ice that forms on the surface of the water when the air temp is below 0 C/ 32 F. On a small scale, it might not be very efficient, but it could save your life on a cold sailing passage if you run out of freshwater. If you scaled it up someplace cold with access to seawater, you could make unlimited amounts of freshwater ice in the wintertime when temp was

I could see this being used to sequester a substantial portion of water in the atmosphere maybe balancing out the temperature extremes and settling the weather down, there would need to be considerations for shifts in ocean currents, but most other issues would be relatively easy to anticipate and plan for.

Your refrigerator used a lot of energy to cool that water down. Keep that in mind when you consider the true cost of that water. It's not free.

This seems like a great new concept. I’d suggest the tower needs to compress the air by a small amount to increase the temperature then pipe the air through air ducts in the water so the sea water can cool the compressed air. When depressurization occurs at the land based plant the saturated air will already be chilled making the condensation require less energy

Great Vid!

Pure genius!

Fascinating! Here in the Bay Area the humidity is often over 100% (San Francisco fog) so it should work fabulously well. It comes pre-condensed! One small nit: You say it may be cheaper than conventional water. The problem is that most out water bill is actually for the maintenance of the pipes. pumping costs etc. People make the same mistake with electric power - in our area the distribution costs are 60% of the bill. Even if the power was free the bill would only drop 30%. But still - a great idea!

What I like about the idea is it poses little risk to the current water cycle operating in these areas. Throw in efficiency gains from better engineering and it sounds very promising.

This is such a good idea. If we use PV and wind turbines at a sea location to draw the vapour and condense it then pipeline it to aquifer injection points we get an efficient water delivery system that chimes in with the existing infrastructure of aquifers. Not sure if the scale of extracting freshwater this way would be sufficient but it is working in the right direction to reduce hurricanes as they are caused by water vapour over the oceans combined with the coriolis affect spinnig up the mass of vapour.

5:16 One of the reasons that desalination is not good is that “..it produces a concentrated salt water solution called brine that is usually pumped back into the ocean where it can wreak havoc by altering local salinity and temperature on the ocean floor.” Logic tells me that this collection and removal of humidity above the ocean surface (that normally is in equilibrium, evaporating and re-condensing at the surface) will increase the local salinity by the same amount as land-based desalination. If the cool water near the ocean floor is used to help condense the humidity into liquid water, it will also have some temperature-raising effect also. It appears that this really cool idea basically moves the system off-shore and gets rid of the pipe that would be dumping easily noticed point-source brine into the ocean.
