Another tech can help solve water shortage, using Nanotech, check out CZcams video from "Undecided With Matt Farrell": Tittle "How Nanotech can help solve the Water Shortage". I want to copy and paste here, but CZcams doesn't let me.
Lol thought of this idea years ago 😂. Back in 2014 could have been rich now if I knew how to make it. Damn
Funny no one’s though of the dehumidifier idea I had all those years ago. Yea water making is damn slow as hell but the electricity it needs would be more cost efficient I think. Make the same item and just add a filter to it
Have you measured the condensation water output of your heat pump? While I doubt it would satisfy all of your needs, i bet it could supply a significant fraction.
12:48 $0.002 is two tenths a penny, graphic is for two hundredths of a penny.
not trying to be 'that guy' but that is a 10X difference. Great vid BTW.
This video covers the most expensive and impractical ways of collecting water from air, while neglecting the most practical methods of extracting water from air (and other places).
The most practical/economical way to extract water from the air, is to let nature do the most energy intensive step (of condensing the water out of the air). For people that don't live in foggy regions where fog nets may work, the most practical way to do this is to install rain gutters on your house roof, awnings, barns, sheds, solar arrays, etc., and then channel rainwater into large volume storage containers (such as big plastic containers like 275 gallon IBC totes or larger, and/or an in ground swimming pool with a cover installed over it, and/or a custom built cistern). The water collected should then be pumped up to pressure with an electric pump, and then filtered with a sediment filter, a carbon filter, and then a UV water sanitizer. Further filtering with a reverse osmosis unit, followed by a re-mineralizing pack is desirable for best water purity and final taste, but is normally non-essential for safety (unless contaminated by algae and/or radioactive fallout, in which case the reverse osmosis stage is highly recommended), if the water was already filtered through a carbon filter and UV water sanitizer. The equipment needed to do all of this in a basic and relatively small system can generally be had for less than $1000 (assuming you use DIY labor), and will generally produce vastly more average annual water output (even in desert locations), compared to vastly overpriced equipment like the "Zero Mass" air/water extraction devices.
Ordinary air conditioners also produce non-negligible amounts of condensate water when running, especially when set to a very cold thermostat temperature. For common whole house AC systems, the condensate water normally collects in a tray under the cold side heat exchanger (often located in one's attic space or wherever the air handler is located). Typically, the water collected is wasted by being piped to a drain that goes into the household sewer lines. One can modify the plumbing on the drain line, so as to instead divert the condensate water to a storage container, whereby it can be purified with a carbon filter and UV sanitizer. Although condensate water is normally fairly clean, it can contain dust from the air and possible traces of mold from the cold side coils on the air conditioner, so it is still preferred to post filter the water with a carbon filter and UV sanitizer before drinking. Trying to obtain large amounts of water in this manner will be very electricity energy intensive however, as it is fundamentally the same as what the grossly overpriced "Tsunami" systems described in this CZcams video are doing. A far more efficient way of collecting water is via a rain catchment system, but capturing incidental air conditioner condensate water is something that is potentially somewhat interesting, if you are primarily running the air conditioner for home cooling purposes, rather than for water capture purposes. The water produced requires far too much electricity to be economically competitive with other water obtainment methods, but when incidental water is captured, it is essentially a "free byproduct" of cooling off your house with the air conditioner.
Although not "from the air", grey water capture and recycling is also more practical, compared to most of the schemes described in this CZcams video. Making potable drinking water from grey water is feasible with a sand filter, a charcoal filter, a sediment filter, a carbon filter, a UV sanitizer, and a reverse osmosis based filter. This can be done both at small scale in a residential setting, and at large scale, and it is fairly economical overall. Some municipal fresh water utilities in water starved cities in the US already do this for meeting some of the city's water needs, by using "reclaimed" water as the input water source. The "reclaimed" water is sewer water that has been treated by a municipal sewage treatment plant, prior to subsequent filtering (including the most important step, the reverse osmosis purification). Cities that do this usually don't like to advertise that they are selling you recycled sewer water, but it is nevertheless still being done in some cities where there is not enough nearby surface or groundwater resources available to meet all of the city's fresh water needs directly. That said, fresh water produced via reverse osmosis filtration will normally be much cleaner and more pure than normal municipal water derived from surface water sources, even if it is recycled sewer water.
Wells and sea water desalination (if you have access to sea water) will provide much more reliable and abundant water, compared to trying to capture water from the air, but there are many ways to produce clean drinking water, and they are not mutually exclusive with one another.
Yes. Way too logical though for the Moisture Farmer wannabes. (I tried to explain it in a previous videos comments but Ricky here really wants to show off this water from air gimmick for some reason….)
a very informative and interesting comment!
As somebody that drinks rain water, you dont really need such a sotisticated filter. A simple filter works nicely. If the water is in a dark place, thats all you need. We also buy trucks of water from time to time, so the clorine of that water may be cleaning the water from micrones, but the water have never tastes to chlorine to me
Aeration and electrification can also reduce microbial growth, to extend the life of filters
PS - first move should be filling in the swimming pool. That’s a huge waste.
The biggest problem with all of these systems is that they work worst in places with low humidity, where they would be needed most.
Quite a few places with low precipitation have surprisingly high humidity. For example, the fog deserts of Chile, Peru, Baja California, and the Arabian Peninsula. The California coast and Central Valley also get lots of fog.
Cloud catchers (nets) are working just fine in desert areas: moroccos is using them.
I kept my dehumidifier in the basement how to get 6 gallons of water a day
use a rain roof to collect rainwater. grey water recycling, and farming practices that conserve water and promote plant growth (many examples of this in north Africa, India, southwest US, etc.)
Wilhelm Reich took 6 (20 ft long copper pipes) and made a rainmaker in the 1950s.
all the so called advance technology in the last 80 years is a joke.
Video topic starts at 5:13 expensive dehumidifier. 7:45 fog nets with nano fibres. 9:13 super sponge hydrogel
Southern Africa has been having some good results from burying clay pots down about 4' under the surface it has APVC pipe up that collects the air and I believe each day it will deliver 11 quarts.
The new atmospheric nets that they make that drain into a communal system could help look up Southern Algiers.
The biggest thing is people need to factor in quit wasting water
I propose making golf course ownership a felony.
The atmospheric nets are in their infancy imo. When its fully developed, we could theoretically reforest entire deserts with the correct implementation. The "lack" of water is really just an illusion
My air conditioner has been pulling water from the air for years
I have a dehumidifier in the crawlspace with a 70 pint capacity. In summer it fills up almost every other day, in winter I don't run it as the radon system keeps the space dry enough. It is amazing seeing the amount of water coming out of the air!
I had a small computer shop on the Outer Banks of North Carolina. I had one too! It produced literal gallons per day and had to be emptied continuously. I had a lot of plants and they were well-watered! I was dumping the rest. Should have used it to flush to toilets!
Hopefully this is satire.
During the monsoon we are having now, I filled my 70 pint tank twice yesterday. I've been using my dehumidifier in an outdoor shed that is well ventilated. Power usage was around 16KWh used over 16 hours. In my area that's about $1.90 total electrical cost for 17.5 gallons. I think I'd sooner buy a fleet of Frigidaire dehumidifiers than buy even one of these "mil-spec" priced contraptions. Think about it, ten $300 dehumidifiers can make 175 gallons/day when its humid or about 15 gallons/day when it's dry, so $3K vs $30K or $50K.
Its not coming out of the air its coming out of the ground, my god this is why "water from air" BS keeps spreading.
@@instanoodles You have to see the difference as long as you are not in the desert or Antarctica there are a lot of water in the air. (Where do you thing clouds and fog come from). What is BS is when you say that you can get it a lot nearly for free. You need lots of energy or very special conditions like morning fog (rain is the real easy way). What is given is that small devices with low energy consumption in dry air do nothing.
Love the pool heat pump idea. Have you thought about a multi-tier system? Think about these add-ons. What about using a cistern system to catch rainwater and use it for non-potable things, such as washing the car, dishes, watering the lawn and adding water to the pool. You can then use the water in the pool to provide water to the toilets. The idea is to reduce drinkable/potable water to that used to drink, bathe and washing dishes. This would significantly reduce water that would be produced by these systems thereby reducing the energy needed and the amount of water needed. We used a 55 gallon pickle drum to collect water at my house for washing the car and watering the lawn and plants. It was amazing. Just after I installed it we a rain that could only be described as a mist rather than a rain. I thought we were going to need a real rain to fill the drum, but that mist filled it in about an hour. ?!? Cistern systems really could reduce the demand for potable water.
Start by reducing consumption. I Cape Town we have been through a recent severe drought. Lots of great ideas have been around for reducing consumption. 20 gal per day per person is fairly easy to get to. Rain water collection, water wise gardens, grey water harvesting. No treatment is necessary if these waters are only used in the garden.
How is this different from dehumidifiers? I'm not a huge thunderf00t fan but he has several videos "debunking" a lot of claims of systems like these as they're not much of an improvement over traditional dehumidifiers. I would be interested in hearing your counter to these type of arguments.
Was just going to say that. It’s a dehumidifier
So do you have to like someone to accept their arguments?
Yeah I need a couple more solar panels that would run my dehumidifier during the daytime so I could justify the cost over power usage.
They are dehumidifiers in reverse. This work great in South East Asia not death valley. Vapor pressure and relative pressure I know this plus wongs. Fog nets supper sponge but everyone is still in labs.
@@williammorgan9622 Isn't a dehumidifier in reverse a humidifier?
I appreciate you posting this, but we've had functioning AWG for years. The most crude version is water dripping from an air conditioner unit. People have talked about de-humidifiers and drinking the water from those. There are battery powered solid state cooling devices that can be used to keep food cool on trips, and if they cool below the dew point, can generate water. Someone posted a funding request for a windmill with additional solar panels to run an AWG in remote areas. But the single biggest problem there is people smashing those things so they can sell the scrap metal. But again, appreciate you raising awareness.
Peltier tiles will work a charm. Cook your bird on one side 🐦 condense water to ice on the otjer
@@derrekvanee4567 they work, but are only about 3% efficient at cooling, so it's definitely not optimal.
popped in just to say the same but I already see a fellow commenter posted this ahead of me :) If I am not mistaken there have also been AWG systems in place in some ancient cultures
yeah, the condenser systems are old and inefficient. the new hydrogel and mof systems work differently though. very importantly: they work at low humidity levels which condensers have problem with. they also use much less electricity, as explained.
Yeah. I agree with the original comment.. just another "discovery" that... Really isn't a true discovery..
Loving your videos. Keep up the great work. I was unaware of the tidal generation of electricity being already used. I have shared many of your videos to my Facebook. Hopefully, your information will be shared and become more widely used.
I live in Houston TX USA. A couple years back we replaced our central air conditioning unit with a heat pump and moved the primary condensation drain from the domestic sewer to the outside (Just reroute the pipe out side). The heat/ac unit is in the attic. Then I bought a 55 gallon food grade plastic barrel and ran the condensate drain into the barrel. Initially, I planned to use the condensate to water my potted plants. Well, after 7 days the drum overflowed. The ac produces over 7.5+ gallons of water daily. That's 225 gallons water monthly. Understanding we live in a high humidity area other areas might not see the same results. I plan to use the water for a 50 ft raised bed garden. Water water everywhere, we just need to learn how to find it.
Use of greywater and other conservation methods means you can cut the 300 gallons/day down significantly. This angle needs to be part of the discussion.
My buddy had a 75 gallon tank in his back yard to collect rain water, and also the water from his washing machine, to feed his garden. That is a practical way to collect some water for your garden.
A 1 KW well pump can produce over 100 gallons per hour to feed the horses on the farm that I lived on for several years in San Diego County.
One other way to save on water - turn off the shower, while you apply shampoo and wash yourself, don't water your lawn, use a dishwasher etc. but as long as water is so cheap and few people will care I guess.
It is said that necessity is the mother of invention. On opening our home to a family fleeing the invasion of Ukraine by their neighbouring war hungry Orcs, we suddenly found that our solar system was struggling to maintain sufficient hot water for two families.
We asked another family who had also provided a safe home for refugees, how were they able to deal with the extra demand for hot water.
"Military showers for everyone", was the answer.💙😉
Back in the early 1970s, when I was in Forestry school, I read in a book something to the effect that as much water flows over the state of Arizona in one week as flows down the Mississippi river in a month, so this doesn't surprise me.
This definitely doesn't make desalination plants obsolete. We just have to actually use the desalination plants and water generators to run them.
I recall reading about a greenhouse system which uses seawater taken from two points at different depths.
Basically the windward facing side of the greenhouse has a simple woven netting which is saturated with seawater taken from the top warm seawater intake. The warm salty water drips down the netting and evaporates as the wind passes through the netting. The sea salt stays in the netting and can be easily removed by simply wacking the netting with a carpet beater when it becomes clogged. The sea salt can also be packaged and sold.
The water pumped from the second intake of colder seawater taken from deeper in the sea runs through a system of small gauge metal piping positioned above the plants in the greenhouse. The highly humid air condenses on these pipes and drips down onto the plants.
It was claimed that these simple and cheap poly-greenhouses could employ 20 people and feed their families and provide enough excess water for those families while still producing enough fresh produce to be financially viable.
the pumps run on solar power needing only a few panels to maintain the electric needs. Unfortunately this will only work if you are near a sea.
I think Desalinization is great for a small usage. And yes can sell the By product until everybody has one. Then there be too much by product to be useful. Right now the DeSales station plants are dumping nearby product back of the ocean which sink’s to the bottom of does grate harm to the Ecology of the ocean. Small scale it’s fine but for the large scale of the World scale shortage of freshwater just too much waste product. They talk about Getting all the minerals out of the waist using it and batteries. But that would only be a fraction of would be able to use.
This might be the 'Seawater Greenhouse' from Charlie Paton. Nice system, good for poor areas without drinking water, it helps for carbon storage (one of 60 finalists out of 1100 participants for the Elon Musk 100 million dollar X-prize). There are installations in Australia that are working well. A new project is placed in the West Sahara (hotel in the middle of nowhere).
@@carstenschoellner2886 Yes that's quite possibly the one, although if memory serves me correctly, it was about 15 or maybe even 20 years ago that I read about this. I never really followed it up to see if it was being implemented. Thanks for sharing that.
This one got som of the pieces of my puzzle growing in sahara to fall in place so I needed to come back and finde your coment to thank you. 👍 We don't need to be close to the osian to get this to work. If just there is plenty of water and there is most places.
@@carstenschoellner2886 thanks for the info 👍
Edit i live in west sahara and never hear of the hotel (time to seartch😄)
So what I'm hearing is that we need a transparent hydrogel coating for solar panels that can absorb water during the night and then evaporate it off during the day to cool the panel.
🥇
Plaster a thick pack at the back of your panels and Bob's your uncle. 🙂
Love it. I volunteer to join you Goblin Army, and will supply my own shiny bits.
Doesn't need to be transparent.. just glue it on the back of the panel
No , put the gel on the back of the panel. It needs heat , not sunlight. Good idea !!
The big question for me is what happens to the atmosphere when humanity around the world uses these technologies. The potential changes to ecosystems would probably create the next global crisis as areas around the world would blame other parts of the world for their water shortages.
I agree, i.e. removing water from air in a large scale would dry the environment and make it easier for forest fires to happen, also not only humans but a miriad of creatures need this humidity to live and thrive.
Indeed, in many places, the water in the air doesn't belong to you - it belongs to the government. Just as you can't dam a river passing across your property and sell the water, you can't pull the water from the air. In fact, they won't even let you save the water that falls from the sky! When I lived in New Mexico, the catch basins that had been used by the original owner to store rain were required to be filled in with rubble and capped, and the rain water diverted away from the basins.
@@TheJLF65 I would love to understand whatever contorted goal that gvmt had with that law.
@@HansSchulze If everyone stored the rain water, much less would make it into the rivers and aquifer. This would mean less water for the government to turn around and sell back to you. No free water for you! How dare you even think of stealing from the government! :) Water in the US southwest is serious business. In the old days, personal wars were fought over it. In modern times, the government strictly controls all water, especially now that it is growing more scarce.
@@TheJLF65 we can't possibly hold all the rainwater... On all the lands... Efficiently... If we did, we might not have any sort of water problem.
For many people a simple water collection system from the rain off your roof with a sizable storage could be enough for your cleaning needs, while one of the systems you talked about could work for drinking and cooking. We waste drinking water on washing ourselves everyday.
Places like San Diego have very little humidity although it seems to be increasing slowly as a climate warms where you need the water the most is Desert communities that have the least amount in the air
Coastal deserts like Namib and Atacama are not only old and very dry but are coastal deserts they have coastal fogs that blow of the ocean at certain points in the year.
Mist nets are the easiest way to passively collect water ...based on the behaviour of key plants and beetles.
Have you lived in San Diego? The normal dew point would average above 55F most of the year, so there actually is a lot of moisture in the air, mostly because of the warm and moist breeze coming off of the ocean. While not as humid as Florida, it is not a dry area, like Phoenix AZ.
But even the most energy efficient dehumidifier, the Santa Fe Impact 155, will make 155 pounds of water from air that is over 60% RH and 72F, per 24 hours, while consuming about 1 KW per hour, that is 9 gallons of water while consuming about 24 KW of power! That is not energy efficient way to get water, when a 1 KW well pump and drilling down 85 feet will produce 100+ gallons per hour of very tasty water.
Not to mention that water condensate from a dehumidifier or air conditioner will have a lot of mold spores, and other things like dust and contaminates in the water. Not drinkable water until processed.
After watching so many Thunderfoot videos on how cost inefficient these dehumidifiers are and cost more than trucking in water, I’m very skeptical.
same, carbon footprint should be shit just based on the inefficiency
Exact same thought.
When there is no water to truck in, the cost doesn't seem so important anymore. Thunderf00t is just chasing a buck which causes him to cherry pick, exaggerate, and sometimes misconstrue the facts. Please stop watching him.
@@Seibar42 He's right on these. This is just nonsense.
@@Seibar42 on the ones I've seen, he projects realistic use and cost and show how foolish these things are for general use.
Even this video reveals this. Look at the minimum daily yield on the dehumidifiers at 5:41 ...0.5gallons for a huge power consumption.
The nets shown only work in foggy areas, on a foggy day. That's not common, especially in areas with scarce water.
Gel may be more versatile, but not yet in production, so hard to say. But its yield also varies depending on humidity and temp. Guess where it will yield the least?
Your final note on using the swimming pool as a heat sink for the cooling part of a condenser does sound intriguing.... until the pool gets so hot that you need to start cooling it! I'd like to see the math on whether the condensation you manage to achieve is wiped out by the elevated evaporation due to heating the pool. Or simply factoring in how much water you need to keep topping up the pool to counteract normal evaporation in the first place.
Really interesting video, especially during the early stages of a drought here in the UK.
Something I wanted to comment on though was your figure for the average U.S househould's water consumption at 300 gallons per day. Here in the UK that figure is around 80 and elsewhere, in Israel for example, nestled in the arid climate of the levant, that figure is closer to 50 gallons. These technologies have an incredible amount of potential but the U.S really ought to seek to reduce their usage at the same time. The smaller Tsunami-500 unit could potentially provide enough water for 4 average Israeli homes, yet it can't even produce enough for ONE single average household in the U.S? You really don't need that much water and places like Israel will be better equipped to deal with a lack of water in the future where the U.S will really struggle to come to terms without acclimatising first.
I think the numbers are BS.
Rain collection and grey water reuse. You could also go get a few off the shelf dehumidifiers and put them out in the yard.
Yep either a couple off the shelf dehumidifiers or some of the roof top solar dehumidifiers should provide all the potable water his family needs, then reuse grey and rain water like you said for everything else. It will make for an interesting plumbing project if anything!
I once heard of an idea for water desalination, don’t know how well it would work: you build a long thin “mini-greenhouse”, say two feet wide and tall and a mile long. A salt-water trough runs down the middle, from which water evaporates. It recondenses on something (what would work best?) and drips into shaded and partially covered collector troughs running down each side.
There are problems with solar desalination of ocean water, one of which is that it is full of nutrients and algae. Microscopic plankton and algae will grow abundantly in the sun exposure of the supply water trough, producing a concentrated slime that will gum up the trough as the water is evaporated away. But it is possible to separate and collect the algae growth as a biofuel source. A large-scale system needs to find ways to prevent this biofouling.
@@DMahalko would grow more than algae...encrusting invertebrates, etcs...would be a bear to clean!
@@mrtechie6810 Make the center trough out of a pipe and cut the top off so it looks like a c. Then clean it regularly with a piston you pull through it. You could use multiple pipes side by side to increase top surface area.
Saudi Arabia is building those. It's a centuries old idea. But unless you are in a dessert, not useful
How about 2 ft wide and a mile long solar panels, and just boil the sea water to vapor right at the input. Eliminate the long troughs.
Have periodic (daily?) automated scraping/cleaning of boiling chamber.
Great news and information. Well presented. Easy to understand, great graphics and well explained.
My hat is off to you Brother.
Ty so very much
God-bless you and your family 👪 ❤️
One thing to consider, typical consumption numbers include flushing toilets and washing dishes. The important part is how much a person needs to consume, and possibly cook with. The rest could use any water available.
"Uses 7 kilowatts per hour" -- correction, the kilowatt is an instantaneous consumption unit, so to find out per hour how much it adds up to, the unit would be then kilowatt-hour. So the correct way to express that would have been "Uses 7 kilowatts-hour per hour" or by simplification "Uses 7 kilowatts".
This kind of sloppiness about units is very annoying to me too.. I can't figure out what he's trying to say when he says 17kW per hour. That makes no sense at all.
I've seen flyers from our local electricity utility making these kinds of mistakes... 😪
There was also the inconsistency with 7.5kWh/day in the narration but graph said 7.5kW (about 10:22) but later the kW were multiplied to get 100kWh/day (12:00ish). I'm guessing the 100kWh per day is the answer that makes sense but that is a huge amount of power. Trying to keep the rough order of magnitude of the numbers in my head and they are randomly being multiplied by randomly inconsistent units.
English isn't my native language but 7kw per hour is saying the same as 7 kWh. Where you get your hour per hour which would make kWh-squared I don't understand
@@bzuidgeest I don't think it is easy to explain in english. More of a maths thing. I'm going to make an English mess trying to explain. Sorry.
The "per hour" implies division by hours so 7kW per hour is the same as 7kW/h which isn't that useful (maybe powerstation ramp up or something). We would use "for an hour" to imply multiplication. Think of a kW as "fast". We could charge "fast" for an hour to get lots of energy (Joules or kWh) in the same way we could drive fast for an hour to get lots of distance. It doesn't make sense to drive fast per hour.
Wow, they built a big dehumidifier. And I wonder about the environmental wisdom of pulling water out of the air on a large scale.
Make the desert drier.
@@tedmoss TRU-DAT, but if EVERYONE was using/doing it, I'm sure that there is a point that there is ZERO left in said air & then the DIY in your back yard users, produces less & less the more the total number of unit online increases. I'll wager that "dustman" was pondering on a grander scale, outwards to the degree of ""WILL THIS BE ABLE TO CAUSE/PRODUCE A SHIFT IN THE NATURAL FLOW OF AIR ACROSS THE PLANET"" since all things in nature want to be EQUAL and a large population area using this technology & extracting every bit of H2O now triggers a deficit so is it all of the ADDED GREENERY that returns its water first, trees & grass & the like or will it trigger an influx from other areas and thus create new and different air/wind flow patterns that end up causing havoc on some other part of our meek little existence on this third rock from the sun?!?!?!?
P.S. Just look at the increased level of skin & lips & finger tips that are cracked & split during the winter months with its lower available humidity. Could we be doing this on a much larger scale??? Just another lil point to ponder.......MR
Yeah, Coastal mountains take all the rain as it is. If you start large scale humidity harvesting on the coast the interior loses rain & has more evaporation.
@@ericmaclaurin8525 California destroying the rest of the country, again! Lol
Here in Tucson we have salt cedars that were brought here over two hundred years ago. When they are small they get fresh water from the ground but when they get really big they rely on the water in the air.
I live in Sweden. Have a cold spring in the woods 100m next to my house. Water constantly overflows the 500L barrier. If I don’t use it, it flows to the creek in liters per minute. 5 Celsius, free and never freezes (-42c is my record here) it’s a luxury
I know what a dehumidifier is, just popped in to see what the take on it is/was here. Just buy any dehumidifier then get a small filter system to treat and filter the water. Your good. The filter system would be the key due to the nature of it and having to literally force the water through the filter.
How about a geothermal style condenser that uses water cooled under ground in a grid to condense water from the air. The trick would be figuring out how to power the small pump. I guess that would need to be done via solar panels and batteries. But I am thinking maybe convection might also work if you ad in back flow valves to keep the water flowing in a loop.
I just bought a large flat style HVAC coil and am planning on initially using cold well water to air condition my work shop. Later I want to use a under ground cooling loop instead of the well water. I am betting the well water at 50 degrees may act as a dehumidifier so I will need a drain, a drain is already built into the HVAC coil so I could collect that water, filer it and then drink it. but do not need to.
In the end places that are vary dry concerning humidity and have no local rivers, that would be a difficult place to pull water from the air. Those places are were this water out of air is actually needed.

I’m definitely most into those nets. I aspire to build a homestead cabin in my 30s and while those industrial Tsunami ones would be fantastic scaled up and energy efficiency optimized for communities, those nets and gels (I can’t really imagine too much use out of the gels though, not sure why) would be awesome for a cabin. I’d still have a well and a rainwater system obviously, but, it’d be great to have that extra diversity and take some load off of the groundwater as the shifting rains dry new ground out, especially since plants in my experience don’t really use humidity as much as we’d think. Awesome stuff with seriously low impact, I love it.
It's just a big dehumidifier with a water filter!
In S. Florida we have the opposite problem. Getting rid of water in the air in the house. So not only do we have an HVAC system, we also have a dehumidifier. The dogs prefer the condensate to even the ground water from the well. If we are lucky, we can keep the RH down to 50% but both units will be producing gallons of water per day. I also use it as needed for top off water for the battery bank.
As someone that works in Water Treatment, it should be noted that the water from all 4 of these technologies would produce un-mineralized and undisinfected water. This means that you really shouldn't drink it and you can not interconnect it to the standard water grid. That doesn't even factor in power to pump collected water to holding or to pressurize holding to your 2nd grid.
Community scale water treatment has many advantages to homebrew. More cost effective desalination (MIT's new system or ocean vapor collection) will blow the socks off of any in-home appliance.
I wonder how long before Thunderfoot does a video debunking this subject again?
I would argue just using desalination and then building water pipelines or other transport methods for a vast majority of situations.
You would have to do an energy analysis of one process against the other to really understand the difference, but I believe desalination is many times more cost effective and easier to do in bulk. I think in certain situations, like if you were to make a hyper-efficient air balloon using renewables where travel is slow and producing water in the air is convenient, or if you are at a high elevation where the transport cost offsets costs, then due to the scenario it may be a better choice though.
I agree, solar or offshore wind energy can desalinate and with existing reservoirs only need to operate when power is available.
Why add the complexity of transporting water from ocean to land when there is an ocean already in the air? If the water can efficiently be condensed then let Mother Nature transport it for us.
@@ljdavick there are a number of issues with scaling something like that, and in reality it is a scenario by scenario basis where you have to look at different options to see which is more cost efficient. In the current status, in a vast majority of situations I think desalination with transport infrastructure is multiple times more cost efficient. In specific high altitude areas it may offset the cost enough to be worthwhile though.
In the real world you are supposed to analyze different options and run optimization equations according to your environment to identify the best option for the scenario. That is how basically all infrastructure engineering works, and while I haven't worked on that specific kind of engineering I would guess they have logical equivalent systems... though I seriously doubt they are actually used to give people optimal infrastructures. Most likely actual engineers are ignored despite having the ability to solve the issue and business people and politicians will decide based on what is most convenient for them in most scenarios
At large enough scale, desalination could be a problem for marine life, since it generates super salty water (it has a name that escapes me right now)
@@noisycarlos you are talking about brine, or dissolved brine in waste water. That would only happen if you specifically chose to put the waste back into the water in unhealthy amounts. Normally you would send it elsewhere to be either processed into different products or disposed of as solid waste. * or if you had system leaks
My family and I have lived in Thailand for about 13 years now and we purchased a condensation electric water system which produces all our drinking water for a family of three. The unit consumes about the same power as our refrigerator and the cost of the unit 12 years ago was less than $1000. We have solar power which produces most of our electric needs. We have saved a lot of money not buying water and have not consumed thousands of plastic bottles. The unit produces a max amount of 16 liters of water/ day.
Always good to hear what's available, feasible, possible, and cost options...the more info shared, the more brainstorming to bring forth more variety, and cost effective solutions, both small and broad scale. I am interested in desalination
alternatives that use magnetic nano technology; & possible cost effective piping to needed regions. Always like learning about small scale, options for dessert areas. Thank you for sharing your research
I have a Rheem Protera 303L/80 freedom gallon’s ;) heat pump water heater. I haven’t measured it but I imagine this would be a much more efficient route as you heat your water it draws in you warm moist air spitting out cold dry air and waste water. Basically a dehumidifier for my basement. I would love to figure out how I can recirculate that in my system. Or just use it in plants in the summer.
The Source Hydropanels at the end actually produce less water than just leaving a bucket with the same x/y dimensions outside to collect the average rainfall in most US cities, if you average it out over a full year. 8 litres (each panel's cited maximum daily output) is about 2.11 gallons and I'm led to believe that Wal-Mart will sell buckets that hold more than that for way less than $3000 each.
You can make your own bucket-feeder system to catch rain for a home storage tank (which presumably you'd need to buy as well to make proper use of any of these systems anyway) for a steal by comparison... or just set up your house's whole roof into a funnel run-off system instead and save on buckets.
Rain capture is out right illegal in some states, in others it's actually encouraged. Last I looked it's illegal (or regulated) in most of the south west.
Edit: For example San Diego is limited to a single 50 gallon rain barrel per residence regardless of number of occupants.
@@Shindinru Well on a state-level, California's only limit is the Rainwater Capture Act of 2012, which seems to mostly just limit it to being used for landscaping needs (gardening, etc).
No US state bans rainwater capture outright anymore although in the past it was the case that it was banned in some states.
Don't forget that with the passive systems you still have to pump water through a filter and possibly a UV disinfecting light and into a storage vessel, then pump to faucets.
Thank you. Most educational.
So these Tsunami systems are basically A/C units. I was hoping for something more innovative. My A/C unit also creates a lot of water as well.
I put a temporary extension tube on the drain tube of my A/C unit and send the water to a drip system for my front garden, keeps things alive at least when rain gets scarce during the summer, and prevents the muddy puddle right next to the house (which couldn't have been good for the foundation).
I’ve noticed that our on demand water heater drips quite a bit of water (condensation not a leak) so it’s now also watering our herb garden via a bucket I empty a few times a week.
It's called a dehumidifier😂😂😂😂they've been around awhile.
true!@
I remember the problem about desalination ...
As I was in South France, Spain and also saw this in Thailand ... build the unit near a salines (salt harvesting area) and offer them the already higher salt water ...
To take the water in the air will ALSO have other long term effects on the climate or sure regions as less water, also less rain.
So Salinas might be better way, as first get drinking water, and after get salt and force more water to evaporate !
We can all benefit from true vaporated sea salt rather than quarry operations.
@@TheEmbrio Yeah, I forgot, that between the desalination unit and the salt evaporation area should also be a rare mineral unit, taking advantage of the minerals in that water also.
As I saw this days a battery based on natrium instead of another rare mineral, a win win for everyone in that chain.
It's so nice to come to an informative and entertaining channel which has videos which do not have that awful fashionable annoying and distracting music over the voice. Those videos will not age well, but these on this channel, with just this wonderful voice, will be timeless treasures. Thank you.
A passive system, even if only used for drinking water, is worth it. Survival isn't going to be based in doing your laundry or taking a shower.
I disagree. And many doctors would agree, I'd bet. Hygiene is very much needed for survival. Imagine never having clean clothes and never showering. Your health would decline far faster than you would think.
@@Nic3GreenNachos Your perspective is based on the made up world we currently live in. Reality is that there are no showers or cars or grocery stores or anything that doesn't occur naturally without all of the infrastructure we have built up over hundreds of years. All of which would crumble in a matter of weeks if an EMP bomb took out the electric grid. REALITY is harsh.
Today's people don't know how to find food and actually know little about what food is. If reality ever asserts itself, 80% of the population would be gone in a couple of months or so.
Given one of the properties of aerogels is (when dry) they’re incredibly light, it strikes me that 33kg might need a huge amount of space - some of the lightest are around 160g per cubic meter, with others being ~1.5kg per cubic meter
So depending on how dense it is, 33kg could take up anywhere from 22m^3 (pretty big, but might fit domestic house plots) to 206m^3 (huge, likely not feasible domestically unless you own a farm)
were aerogels mentioned?
It may be a small amount, but take the waste water condensation pipes from your home AC and store that. It may not add up for home use, but may aid in watering a garden.
Uncle Owen on Tatooine was a water farmer.
All you need is 200 foot of pipe (6 or 8 inch PVC) sloping down to a tank . Say start a foot above ground, and have the tank 10 foot down or deeper. Have a second pipe coming up from the tank with a SLOW fan pulling air through, the humidity will condense on the cold (60F) underground pipe, and run down hill to the tank.
A small pump and pipe to get the condensed water out is the last part. This will be distilled water so do NOT forget your vitamins and minerals . Don't thank me, thank Uncle Owen.
Owen Lars was a human male from the desert planet Tatooine who worked as a moisture farmer.
I like you analysis. I looked into capture nets in the past 10 years. I live on the coast that has fog nearly every morning so it seems ideal. However, afternoon wind is quite rough on the equipment and sunlight breaks down the nets quickly. Then there's birds.. finally filtration is still needed.
Id put them on rollers, that are rolled in during the day and rolled out at night, that could even be part of the collection process, few birds fly at night, so both problems solved, you could also just put out cheap netting permanently to stop birds that ae early risers flying into the capture nets.
@Digital Music Hobby The nets work all day and night with as low as 4% humidity, you don't store them away. It uses the sun to heat up the fabric on one side and the wind to cool and condense on the other, your ideas won't work.
@@LOFIGSD good suggestions
@Digital Music Hobby that is worth trying. Thanks
This is one of the subjects I've been looking into the fog net. Seems the best, self sustainable, cheap and no electric required option out there.
Look forward to your progress and updates. Thanks for sharing 👍🇬🇧
Rain water collection would be a better and cheaper alternative most places. Even in the Arizona desert it will cover your needs for long stretches of time.
@@bknesheim i think, especially in Arizona, the fog net would work far better.
A fog net made from natural fibers will slowly rot from being constantly moist, until it falls apart and has to be replaced... A fog net made from plastics will gradually degrade from ultraviolet rays from the sun, releasing microplastics as it debonds, until it falls apart and has to be replaced.
That's what morocco is using.
@@DMahalko it a water collector, not a water cleaner. You don't collect water from a river or roof and just use it. Material degradation isn't much of a problem. Distil what you ingest.
Cheap, low maintenance and able to provide relatively clean water. Sounds like a win to me.
There is a small scale that is at any big box store. Just get a dehumidifier. And have the outlet go to external storage. Then you have to do your own filtration from there but you can get water from air for just over 100 bucks. This will not be making enough to support your daily use or for the household but in a pinch when you need water from the air this is how you can do it on a budget.
We had one of these 'tsunami like' units in our basement in the 1960s already, we called it a 'de-humidifier.' It made a lot of noise and a fair bit of heat but it did yield several gallons of water per day. Of course we didn't want it and ran it down the drain.
There is a difference between the amount of water you need versus what you'd typically use, I suppose. So from just a survival aspect, you wouldn't need 300 gallons per day. For some applications like flushing your toilet, perhaps there are other options like reusing Ggrey water rr even a composting toilet.
Yes. The real answer includes a lot of water conservation. For personal use daily, we could be using just a couple gallons of water showering, a couple for cooking and cleaning dishes, and a couple for consumption (on a typical day). We could and should reduce use for purely non-food (ornamental) plants, like lawns by a lot.
Note also that piped flush sewers were an invention to allow more growth and disease-reduction in cities in the mid-1800s. That doesn't mean they're a solution forever. Perhaps we should consider solutions where we don't mix good fresh water with our dung? Maybe robotic drying and collection systems?
No worries; Fritz Schlunder (above) says you just drink your sewer water after running it through a filter. Problem solved! Piss never tasted so good...
I moved into a house with a spa recently. I was surprised to learn that you're supposed to drain/refill them pretty regularly. I was definitely annoyed when I had to figure out how much it would cost me to refill my 1300 gallon spa after I found out water was priced by hcf. However I was surprised how little it cost for that much water.
Spa water contains water treatment chemicals, so does not need to be changed frequently, providing it is correctly tested and dosed.
@@kitemanmusic the water does get treated, however there are contaminants that dissolve in the water more easily than the pool chemicals and cannot be filtered out, reducing the ability for the water to hold cleaners or maintain proper ph. Maintenance can prolong the life of the water but compared to a swimming pool, removing the unwanted material is more costly than just replacing the water, given the size of a spa.
Since you are in San Diego, and near the ocean, consider this: Forty foot high towers above the maximum high tide level (actually a U shaped pipe) in which the South side is black and the north facing pipe in the shade is white. A near full vacuum is created at the top of the tower (loop). The sea water essentially boils on the sunny side, and fresh water condenses on the shady side. Pumps push the fresh water to holding towers while making sure that the tower pipes do not go dry.
Salt concentrations will go up in the local area, but sea life will likely evolve and adapt to that environment. Also, at night fresh water would condense on the South side pipe which would help keep salt build-up from being a problem.
As far as natural condensation nets, I have found that if I let my pasture grass grow, I do not need to water and it stays green until late July, to early August. My back yard is now just starting to turn to straw with one variety and good seed heads. Another variety is still rather green and just starting to dry out on the seed heads. I've not irrigated at all this year, and I live in a high desert.
Here in New Zealand almost all houses in the rural area do not have a town supply. We collect our own from rain water or stream or bore, most of us realize the importance of water conservation, the idea of using over 300 gallons of water per day for the average house is insane, yes some of these technologies look valuable. however the more frugal use and ensuring the system is in good order would go a huge way to alleviating the problem. A change in the ecosystem of housing would also help a great deal, I know some areas in the US are already doing this.
I just watched your video, water from air. Judging by my own experience, I think a lot of air conditioning is needed by humidity in the house. It seems that these more passive techniques can assist with this. For regular AC, dehumidifying uses close to the same energy as AC. If we could incorporate a dehumidifying system like these, we could lower the need. Even if the net needs charging, it would certainly be much less. That would certainly be handled by solar. I don't really understand how to use the gel, so not so many ideas. What do you think?
Great video! The only thing to also consider in these options is maintenance. Dehumidifiers need cleaning and their pumps get clogged. I'm sure nets get dirty and need cleaning
That's why you use filters
Jamie if your dehumidifier pump gets clogged then it's badly designed
desalination can be done without power input (other than ambient heat) flood a field to a shallow depth covered by a clear slanted roof. water evaporates condenses on the roof and rolls downhill to a collection point. mush slower than using a boat load of electricity but it works best in areas that are dry and hot, which is also where the most water is needed. after several cycles of flooding and evaporating - collect the salt left behind as a bonus
I installed a heat pump hot water heater last year and collect the waste water from my unit. I currently produce 5 gallons a month (average) and have it stored for emergency water purposes. Since I make BIOCHAR I can use that to filter the heat pump water if needed. Nice presentation.
It's a de humidifier with a filter so why do they cost so much?
Not the way to go, unless absolutely necessary.
The only thing I can think of is the 20 year warranty of near constant use and they haven't scaled up, or maybe they are looking to sell them to a Saudi prince or something 😅
DIY idea: a hollow backing behind your solar panels. Blow are through the system to cool solar panels (improves efficiency), then run that warm air to a closed system below or around your pool to cool the air. Then to a condenser that extracts the water.
Think of it this way. Condenser/heat exchange unit in the middle. Hot air comes from roof. Cool air from the pool/ground.

Living in the Arizona desert, water is a major concern. The “fog” nets that can be used in a more arid environment is worth watching. However, I suspect the net would not survive ten years in our intense heat/UV environment.
One point about the ZeroMass system is the noise, it’s LOUD.
EDIT: What I'm getting at is of that 300 gal/day the majority could easily be replaced with lower "quality" gray water.
Honestly a "divide and conquer" approach is the best way to go about it.
Gathering gray water (rain runoff, water from ACs/dehumidifiers, etc) for non-potable uses, while reducing usage through high efficiency machines (for clothes and dish washing) and closed loop showers for people/pet washing.
You only need potable levels of filtration for a small amount per day, usually in the 10-20 gallons range for a house.
It would be interesting to see how well each of these work in someplace that is truly dry, like Yuma, Vegas, or Bakersfield. Maybe a head to head competition to see which can produce the most water in a 72 hour period. Limit each to a system sized at less than $100/month cost for energy and amortized capital cost. If the manufacturers truly believe in their claims, they should welcome that chance to prove themselves.
Good suggestion.
No way they will do that.

@@nenmaster5218 Thanks- I'll check
Have you ever used a dehumidifier? Have you ever tasted the water from a dehumidifier? It's nasty but anyway I wonder about the hydro gels. How do you extract the water? Do you squeeze it to release it so there has to be some kind of electricity used at some point so there's that cost too, right? I don't know. I'm very curious about the hydro gels. I don't think the nets are going to be all that practical. Can you imagine if you live in an area like I don't know San Francisco somewhere along the coast and everybody on their roof has a as one of these net systems? I don't know if that would be acceptable from a Civic standpoint.
he have AC unit, he can try the water 🤣🤣
heat releases the water. so it can be done passively, like in the example he discussed of the sun releasing the water during daytime. Or, what he didn't really discuss, is a hybrid system which uses some electronics to heat and cool the system to get many cycles in a day, instead of just one.
Tasting nasty is the least of it. Untreated water can be full of harmful microbes. Blech! Processing is absolutely necessary!
First step is to reduce the amount of water one uses by, for example, buying a circulation shower that filters and re-uses the water. This should save a lot of both money and water every year.
Those Tsunami machines makes no sense from a economic or energy perspective. All that wasted electricity could be saved for something else, like cooling the house *and* charging a car at the same time.
Fog nets on the other hand is a proven technology, cheap, requires no electricity, and last a long time. Hydrogel also sounds like a promising technology.
Simple rain barrels are also a option if it rain regularly where one lives.
I drilled my own water well less than 25 feet deep for under $500. I hand pump it, drink it and water plants. It currently costs nothing but it also builds biceps. I take 10 gallons a day from it. It should make more after deepening to 17 feet. Add a solar electric down hole pump should be ideal. I think we may use in the house 20 gallons a day!
Great video, thanks! Would be awesome if you could make the calculations in SI units.
Devils Advocate: Is there a threat of overdoing it taking so much water out of the atmosphere that it negatively effects the water cycle?
No 😀 (even if these were feasible and my money says none of them are except maybe the nets in very specific environments )
The water doesn't just vanish. It remains part of the cycle and eventually returns to the ground or atmosphere after being used by people.
And to add to above; if we were to reduce the moisture content of a section of the atmosphere, it would simply absorb more as it is normaly at an equilibrium to which it will attempt to return.
The planet is too big, it cant affect it. It's like saying humans can change climate, it's just too big for little humans to have an effect on it. Any 1960's teacher would have told you that, it's so obvious.
@@Joe-lb8qn I know it doesn't vanish I was more talking about water storage.
The simple fact is that places that have trouble getting water often lack the level of humidity needed to make water condensers effective. Places where you can collect water "out of thin air," it's typically massively abundant. The only way that I could think of an aerial condenser system being a good idea would be at sea, where you could build a massive scale condensor project to collect moist sea breezes, ones that would be unlikely to turn into useful land rain on their own, and then dumps that water into storage tanks to be transported inland where they need it. You could perhaps do this in the various seas around the Middle East, for example.
GREAT RESEARCH.I Love your videos
This sounds great...especially the fog net (I think it's the best of the three). I'm wondering though..."How will the use of these systems affect the atmosphere/local weather?"
If many persons in a given locale are using the system(s), would that compromise the possibility of rain hence, the water supply to the rivers etc.? 🤔
Scale up to an entire country or continent using these systems, then...😯
That's taking the rain before it falls. This may exacerbate water shortage 🤷🏽
What do you guys think? 🤔
It would affect rain in other places just like wind mills affect the air movement of places down wind of them. You could argue that this is controlling where the rain falls so less gets waisted but then that could lead to more water wars too.
If enough are placed along coastlines, then inland areas will get a lot less rain and moisture. Most likely making the problem worse as lakes and rivers dry up.
@@pyronac1 This is a possible scenario yes.
Existing Fog Nets are used in just a handful of places like high cliffs, at Coastal Chile which are known to have fog daily for about 9 months of the year. There is simply so much fog, being blown inland by strong coastal winds, there there is no chance of "running out" of fog. The Fog nets would be catching not even 1% of 1% of the available fog. "Theoretically" if enough people had fog nets, might it be a problem at some far off future date ? Maybe. But very few parts of the world have exceedingly low, almost zero rainfall, while also having very VERY high fog levels. Like all day all night 9 months of the year dense fogs.
@@KiwiCatherineJemma Wow! I did not realize there was so much fog for such an extended period in any area! 😳
If such a miniscule amount is harvested, then...point taken 👍🏼
Great video! yes.. I would love you to review the mini desalination units that Manoj Bhargava talks about in his documentary?? It seems like they could be floated up and down the coast of California to refill some of the ground water that has been overtapped to prevent saltwater intrusion. Love to hear your thoughts on that.
And, like others surely have commented, have a look at rainwater storage, and separating drinking water from water needed for washing. flushing, etc.
In the nineties I opened up Air, Water & Ice inc to promote the use of condensate as pure drinking water and clean clear ice.
The other aspect was using the water from a de humidifier for reef keepers.
I’m interested in scaleable water systems that can have impact far above individual needs. I think this is going to become one of the key planetary issues of this century.
I’m looking forward to additional development in this area, great video, thanks.
It's already happening. Check out morroco they are using the cloud catchers to provide watter to distant arid areas making huge improvements to the people living there.
Surprisingly Israel's water desalination is fairly cheap.
@@autohmae- Israel's seawater desal is Not cheap enough for mass agriculture in open air. But that is mainly because plants in open air are incredibly wasteful of water and solar energy.
@Ray Miller - Be on the lookout for an emerging technology called The Updraft, which imitates Nature's way of squeezing water from air and even improves on it by producing power, too. Both on quite a large scale.
@@YodaWhat depends on the country, for example the Netherlands uses only 10% of the water of many other countries. So it's a matter of knowing what to do and how. But I agree, we should transition to methods of using less water where possible.
Couldn't you passively produce the wind needed for the mist netting or hydrogels with a solar tower? As the tower heats the air inside the chimney, the rising warmed air draws more air in from the base. As long as the temperature differential exists, it will continue to function.
Yeah! That’s a good idea… but lowest temps will yield more water capture
@@TwoBitDaVinci Yes. So the mist netting could be placed around the inputs (i.e. lower level windows).
Great study thanks
Also don't forget that when one person takes water from the air, it's not instantly replaced. If you had a whole neighborhood full of these devices they would all be struggling against each other and the total water production per unit would be much lower
Awesome video, I don't get how we use liters for soda, but everything else is typically measured in gallons. We already know what a liter is visually why can't we use it for everything else and make conversions so much easier! Same thing with cubic centimeters. The roof mounted solar collectors looks like it has promise in areas where freezing isn't an issue, like in most desert areas that really need it.
Someone needs to finally adopt the metric system! Signed everywhere but Liberia and Myanmar! ;-)
someone once quipped, "The nice thing about standards is that there are so many of them!"
soda is sold everywhere in the world thus -- to reduce packaging variants its easier to make one. milk, juice and ESPECIALLY water - are TYPICALLY only produced locally (minus dasani, etc). This actually because products that don't cross state lines like water aren't subject to certain FDA regulations.
Locally produced goods wouldn't bother putting metric on - because derp we're in murica!
Its very simple. Areas with low humidity have limited fresh water, areas with high humidity usually have plenty of fresh water. That's all you need to know to understand how pointless this technology is.
The most energy efficient dehumidifiers consume 1 KW per 10 - 15 liters of water removed from the air. And that is when installed in a very high humidity room, such as a pool or other places with 60% RH or higher.
The Santa Fe Impact 155 dehumidifier will cost less than $5,000 and will produce 155 pounds of water every 24 hours, while this unit will draw about 1 KW per hour. But if you are using 20 KW per day, that is a lot of money to produce 8 or 9 gallons of water each day.
Getting water from the ocean is very expensive, but this system with taking the moisture out of the air is well over 10 - 100 times more expensive than the systems used by a small boat to get drinking water out of sea water.
Here in Arizona, my AC condensate is producing 10-14 gallons a day during monsoon as a byproduct of cooling my home. In dryer weather, 5 gallons is common and we make use of it watering plants. ZERO investment.
Another great video as always! IMHO, California needs to invest heavily in renewable powered desalination/lithium extraction in conjunction with fixing the Salton Sea one way or another... Since there are 11 lithium extraction operations proposed for the area using renewables as well it seems like one the largest environmental "crissatunity" moments for California in its history... Also SMR's since nuclear itself isn't the issue. It's what to do with all that still radioactive "waste"... Then again, the French have mastered that with reprocessing/recycling/transmutation and glassification of low and medium level waste.
Don't forget nuclear waste diamond batteries...
Maybe instead of wasting energy in these crap solutions. You could just fix the bad water management rules in California or remove those idiots farming in what is basically a dessert. California has enough water, it just lacks people being smart about it's use.
@@bzuidgeest those farmers are making money which is essential for an economy - to produce something.
NIMBYists in California only want pollution and mining in China and Africa, far far away from their favorite nature spots.
Nuclear "waste" has been exaggerated by the news and politics. It's never been an issue. You can easily store it above ground in silicon and concrete casks.
If billions of people start pulling water out of the air, would it stop raining as often? If so, wouldn't that be a major issue?
I doubt it would make a major difference but there is also a major plus - water vapour is the strongest greenhouse gas, Pulling water out of the air would have a cooling effect on the planet!!
If billions of people started all pumping wells, or desalinating, or pluging in electric cars, or doing any other consumption simultaneously, it would be the end of the system regardless of the activity, lucky everyone runs in different directions quite evenly IRL
One additional cost to factor into water extraction systems compared to a community water connection is that in the latter the water arrives under pressure. So with the water extraction system, it at least has to be mounted up high, or you need a pump. Not insurmountable, but just something to include.
Not for homes, but there are two VERY interesting water solutions I've seen. Both are unfortunately coastal only, one allows for the direct conversion of wave energy into desalinated water, I believe without the need for an electric conversion -- capturing the mechanical energy of waves to pressurize the water for desalination. Another are essentially massive collection towers that sit just above the ocean surface, allowing for fresh water to be collected at incredible rates.
Being in our nature to mess things up, how many of these systems would it take for us to dry out the air to the point we reduce the normal amount of rain? Imagine it would be orders of magnitude higher than I can imagine, but an interesting question. Thank you for the great content.
Find out about the moisture that rises from the ground on a daily basis.
Aside from the title being clickbait, none of these solutions is going to be the silver bullet. Water depends on the local climate conditions and cost of each method. A multipronged approach is needed (from least expensive to most):
- Conserving water by planting lawns with low water use plants, leak repair, better toilets, etc.
- Large storm water collection projects. Collection systems dependant on weather are unreliable: $230 - 260 / acre-foot
- Brackish desalination: $840 - $1,200 / acre-foot
- Non potable reuse (may cost more due to infrastructure): $550 - $1,200 / acre-foot
- Indirect potable reuse: $1,100 - $1,600 / acre-foot
- Desalination for extremely arid areas: $1,900+ / acre-foot

The first one might work during the day when the sun shines and the wind blows, especially when it comes to public water supplies. When the grid is overloaded with solar&wind power, utilise the redundant power to make public water.
With a water use of over 300 gal/day, it should be relatively easy to realize significant savings. In the Netherlands, the average 4-person household uses less than 150 gallons per day. One of the significant differences is that we have smaller gardens that need less water in the summer. Also, we do not have that compulsion to have a lawn front and back. From what I have seen on youtube and docu's, redesigning gardens with climate-appropriate plants, shrubs, and trees (shade) would reduce water use meaningfully.
Also, and I am not up to speed on the efficiency of your dishwashers, washing machines, etc., but in Europe, yearly water-use of these machines must be mentioned along the energy use label, so buying efficient machines gets promoted.
Another option could be to use drinking water only for selected use like drinking, cooking, shower, dishwasher/washing machine (with catchment to gray water when possible) and use gray water / rainwater for your toilet, garden.
I have not yet seen anybody looking into the one risk I see that could come from the mass use of these systems. With millions of these in use, the relative humidity in the air could drop just a few percent, but that may also just be enough to significantly influence natural precipitation patterns.
This is one of my favorite channels. The content is just so damn interesting.
You're baiting Thunderfoot to debunk these, right?
what a sad world view. nothing here to be debunked... just comes down to commercialization and costs etc.
@@TwoBitDaVinci Yes, nothing to be debunked (again) here when scientist have already debunked it decades ago. Infomercial clickbait.
@@TwoBitDaVinci the issue isn't does it work, the issue is the energy consumption. As another poster pointed out if it's cheaper to truck in the water the extraction system is pointless. There's been alot of startup scams in this particular space.
Thunderfoot isn't an expert in anything except his Chemistry PhD. Therefore his opinion is no better than anyone else's. The only thing he's got is a posh accent, some editing skills and an ego the size of a blue whale.
@@jackinthebox301 you're missing the point, these three systems are not commercially viable. 50k upfront and 1k per month is ridiculous, others needing land AND daily fog only fits a very small population of the world.
Giving a company a platform to promote energy intensive processes to the detriment of the environment is not morally right. There are far cheaper and better solutions to water shortages. This video fails to provide a balanced comparison and comes across as a promotional video.
Most American residences have forced air HVAC systems which, especially in the warmer seasons, condense water from the atmosphere. I have a 320 sq ft tiny house on my property with a 1200 BTU mini-split unit for both heating and cooling. On a typical summer day, here in Central GA, it condenses between 3 gallons and 5 gallons of water while maintaining a 74 degree F temperature inside the tiny house. We capture that water and use it to water plants and the small amount of small livestock we maintain on the property. The 1200 sq ft house in which we live has a 4 ton heat pump/ac uni that produces nearly ten gallons per day of condensed water on typical late spring to early fall days when the temperatures range into the high 90s and humidity is not far behind that number.
Combined with a proper photovoltaic array and storage batteries, this could all be run, after amortizing the initial investment for the infrastructure, FOR FREE.
To make that water potable would require nothing more than proper treatment and filtration. But it doesn't have to be potable to be used for non-drinkable purposes. I'm dismayed that this water source is not being exploited.
