An atmospheric water generator (AWG) is a device that extracts water from humid ambient air, producing potable water. It works best in hot humid conditions and pumps near freezing water through a simple design. The AWG is composed of high-quality components and can be made for home use. Researchers at MIT have significantly boosted the output from a system that can extract drinkable water directly from the air even in dry regions, using heat from the sun or another source.
Water-from-air devices, also known as AWGs, can be extracted through various methods, such as pyrolysing methane to form charcoal and hydrogen, which are combined with oxygen to make water. The water is then collected and stored in a small, almost passive unit with minimal moving parts and minimal moving parts.
To construct the AWG, two half-inch PVC pipes are taken and connected using two elbow joints. The heat exchanger is installed inside the chamber to cool the air and help condense the water vapor. The AWG is capable of producing potable water, similar to moisture farming in Star Wars, and can be used in hot humid conditions. The cost of building a DIY AWG is relatively inexpensive, making it a cost-effective solution for those in need of water.

OPTIMIZATIONS IDEAS: (make water by the gallon using solar) 1. Get a 12″-20″ fan. Point the fan at the coils and turn it on. You should test if the fan speed alters condensation rates. I guess a 3-5X improvement on water condensation. You could get a 12V fan, a 100W flexible 12V solar panel and a 20AH 12V battery for <$110. Not sure how you are cooling the tube fluid, (ice?) this two can be powered by solar. I run my refrigerator and home lighting with solar. (soon to do the TV & HTPC too) You could put this thing on steroids by pumping freon (or equivalent) through the copper tubes using a solar powered condenser. It would likely be to cold causing the condensation tubes to turn to ice. Keep the gas flowing with the compressor only coming on when the gas is warmer than 38* or so. To vertical or not to vertical? If vertical, the water will not have as many places to drip off from, with a constant flow of water dripping round and down the coils, you may end up with less area for condensation to take place as the water from the top down becomes a river covering the tubes with water. You want the maximum amount of the tubes surface area exposed directly to air. Although, it's possible I'm wrong about this and vertical is actually is the best. The water dripping round & down may clear the tubes from water faster than vertical. A test may be in order. Do this right and you could save $ on your water bill for a small investment.
Cool project (pun intended)! I would suggest orienting the tubes vertically over a funnel that is inserted into a 5 gallon water bottle. I would also suggest using one of those Peltier junction electric coolers to keep the water cool, rather than relying on those freezer packs. You’re still going to be using electricity to cool the water, but you’re not going to have to keep rotating the freezer packs to keep the system cool. Alternately, you could use a small compressor refrigerator with a water bottle or bucket containing the pump inside and just drill holes through the wall for the copper tubes. Compressors are more efficient than Peltier junctions, but they are mechanical and would wear out, whereas the Peltier junctions last forever and require no maintenance and make no noise. If you’re powering the system from solar, the Peltier junctions make more sense in the long run. Thanks, for sharing!
Most people already own an Atmospheric Water Generator…it’s called an “Air Conditioner.” My rooftop HVAC produces so much water dripping off the cooling coils that building codes require a drain line to keep from staining the roof and sides of the house, and this is in Nevada where single digit humidity is common.
What if you sealed your collection container, exposed it to the sun, whilst running FREON through the coils? What would your condensation/water output be, then? You might have to change the direction of the coils, turning these in a vertical position, maybe? Next challenge might be to make it solar, for third world countries. Also? I would use strictly copper and skip the aluminium. My last worry would be the loss of electrolytes/minerals as this would be dead/distilled water. We would need to find a way to re-mineralize the condensate. Kudos to you for seeking solutions, Buddy. Well done!
2 inch diameter inner copper coil (tightly coiled) and a 2.5 inch diameter copper outer coil (tightly coiled) vertically (2″ diameter inside the outer coil) 5 feet long dripping water 24 seven into an IBC tote. Summer or winter this gives us water year-round. Use your indoor temperatures to create the temperature differential you need versus the second air pump drawing air from your garage or outside. Nothing more than swapping the air lines per season. Hope this helps everyone God bless.
DC water pump run off solar panel. Ice bucket with ice and water inside, with the pump. You will need to keep replacing the ice in the bucket. The solar panel will keep running the pump as long as there’s enough light hitting it. The pump may run slower if light is lower. Might be good to get a solar panel that has a chunk more watt-output than what the pump requires, to get best output during daylight. The pump recirculates water through the copper coils, where the cold/warm differential causes condensation from humidity in room. As far as I can tell, the aluminum foil on PVC pipes is only to support the copper coils…though, the aluminum foil might reflect radiant temp at the copper coils?? –> IF you set this system up, you will want to put it inside a protective case, fed by air stream that goes through an air filter, to keep the condensate clean…OR, will need to run the resulting water through a filter, to remove dirt, bugs, etc. Humidity is relative to the site you are…but there is still humidity even in deserts …though, desert locations will have more humidity below ground… You can harvest humidity from ground in most deserts, by digging a hole, setting a cup or pan at the bottom, covering top of hole with a plastic or glass membrane that is pushed down in center or tilted towards the cup…..during night, hole is cooler; as daylight begins, water condenses on underside of membrane and drips into the cup. ALSO…one can harvest humidity from large shrubs…though, you will want to be sure those are not poisonous shrubs.
když použiješ mrazíci box napojený na solární panel a otevřený dvířka udělá se silná námraza a když to vypneš a zavřeš budeš mít dostatek vody ze vzduchu. Mrazící box pojede na solární napájení na maximum a vytvoří se lez. Pozvolným ohřátím na přijatelnou teplotu se led změní ve vodu, která bude na pití. Získán z atmosféry. V krátké době. Podívej se do lednice když ji nezavřeš udělá se na zadní straně námraza a když ji zavřeš po chvíli tam máš vodu.
So you need a freezer to freeze your cooling blocks i saw lieing on your table. You use them to cool the water that runs thru the copper coils. Maby do a project to use a solarpanel to run tbe pump and cool the coils by putting some hoses or something under the ground where it is cool. Would be awsome to see it that works. Then it woul be a great of the grid thing .
On a different article, I watched a 500 Watt (minimum size) Jackery power a countertop ice maker. Power stations like the Jackery can be recharged via portable solar panels. If the resulting ice were used to cool the water in that Styrofoam cooler, this atmospheric generator would work during power outages. (The power station would also run the pump) Two 500 watt power stations, 1 recharging in sunlight while the other operates the atmospheric generator, might work well. After the ice melts, put the water back into the ice maker and turn it back into ice to keep making more water. Might be handy during an emergency if local conditions are right. Thanks for showing this article.
Why the aluminum? Does it preform a function?? Thank you 🙏 I live where there isn’t even a municipal water system offered and I must haul water even though I live within the city limits. I’m thinking of building this with a funnel catching basin and having it drain In to a cistern basin instead of paying 80.00 dollars per 1500 gallons for city water hauled by truck.
Consider using cold air from your AC unit to cool the inner diameter of the coil. And the opposite for winter, keeping your coils in a cold area. Condensation year around without the need for ice – just use an air pump. You need a 25° delta Fahrenheit to achieve condensation. The higher the delta, the better the condensation to relative humidity. Hope this helps.
Better running it somewhere with much higher absolute humidity, get water warmed by the sun? Easy to get to 40C 95% with a covered pond. Liked the focus on potability, I’d be using a ceramic dish not the aluminium. Near brackish water should be OK, pollution from salts or most bugs shouldn’t be jumping across, oils might.
Adding freon won’t do the trick as freon operates under compression and expansion in order to become hot and cold. What I was wondering is having a containter of water underground that keeps colder from the earth. I have a rain tote that has a tarp over it that does keep colder than ambient temp since it’s shielded by the sun. I considered running a pump inside the tote to a coil similar to yours into a box that will recirculate back to the tote. Air flow going against the air flow is key. Pretty much the basics of any exchanger. Adding some sort of baffle or website to force the air in the desired direction might help as well, but this would also require a method of drainage and collection to see if it actually works. Solar panels with a backup battery would be nice for when the sun goes down to continually move the air. Night time may chill the water to a degree and condense water vapor. Box that coils go into I would like to think would benefit to be black or shiny with glass front.
All you need atually the copper tube for condenser and pressure release valve and a tire inflator or a wind cathing to push air through pressure valve then expand in copper tubing with large volume expansion and some way to get enough air through but not too fast then most probably alot of water enough for cooking for family
Greetings sir! I’m very much thankful to you for this project. I wanted to make this in a national competition. Could you please let me know how you did this and what all you have used? It will really be a great help sir. Please make i as soon as possible because I’ve my competition ending of this month (April). Thank You
Wouldn’t it just be condensing on the outside of the copper tubing because of condensation you’re putting a cooler inner atmosphere and direct contact with a warmer outer atmosphere I don’t know exactly what you did here so if I sound stupid as f*** just know that this is off the hip and I’m just thinking of a cool soda can that come out of the fridge sitting outside on a 90° sunny day
(Thinking here any help is appresated) Ok so what I need is a way to cool water1 (refrigerate to near freezing say 34 degree) Then move the water1 by 12v pump ( ok this is already found, a boat bilge pump) through coil Cooper tubing. This causes condensation ( water2) the water2 is collected in a catch pan. Which can drain into a sump ( a better word can be used here but I can’t think of the word atm). Then the water1 is returned to cooling system. So need a way to cool water1.
I’m still in a house now and I get my water for free out of the side of a mountain to wash fruits and vegetables off with.. But when I move off grid I will definitely be trying to save my air conditioning and dehumidifier water for hand washing, and bathing. I’m looking more into making water on a bigger scale. so I don’t have to go get the free spring water out of the side of the mountain. or I may have to buy it when I move way down the road or out west. If I can’t get free water.. My humidity in my house yesterday July 10th 2019 was right at 70% humidity. I don’t guess this would work as good in Southern California or Arizona. or in places like someone said out west humidity is in the single digits a lot of times. But as long as it will still make some water is the thing. If I was trying to make drinking water though. I would use the boiling water method first. But for bath and hand washing water copper is ok. In my area we have about 5-6 places to get free fresh cold spring water flowing 24/7 year around out of the side of a mountain. This water is far better then recycled tap water. But distilled water still is the purest you can get if I could only get it for free out west enough for my family. The only water I mostly drink is alkaline oxygenated 9.5 pH health food store water for $0.99 a gallon. I would only drink other water in a disaster where no other water would be available and I couldn’t water boil distill it or buy it. Tap water is a slow form of poison. I might shower, wash my hands in tap water but I definitely would not consume it.
thanks be to God I have an idea for a proposed Air conditioner machine that can be used to collect water thanks to the maker of this device. using small current and voltage, one applies it to a hollow ring of copper placing inside freon r12 with metal shavings ( small pieces of metal dust ) hypothetically speaking the current shall and may make the attracted metal and magnetic field spin the gas at high rates thus cooling it dramatically causing henceforth droplets of water to form same as the YouTube aparatuses’ machine. God willing. any thoughts or improvements? (- for the sake of humanity free, water to all)
What is the coil – is it copper? Where did you find the copper and the condenser (box) for purchase (could you please provide a link or location/store)? Also, I was wondering the tubes, are they just simply store-bought tubes or do they need to be purchased from somewhere specifically? Your article has already helped me greatly with a school project I am doing, and it would help me even more if I could get ahold of the materials used in this article. Awesome idea and article, good job!
This is distilled water. You start with water and thru a distillation process, create more water that would be of a better quality. It’s like catching the steam from a boiling pot of water or food – that water or steam is distilled from the original water. This is not creating water from air, its basically sweat. The same thing happens at the fast food joint on the outside of your soda cup. That water which accumulates on the outside of the cup is in a simple form, distilled water. This process here is creating better water, from maybe questionable original water not water from air, since you start with water to begin with.
I have an amazing idea that we could work on together that would not only give us a nice level of wealth but more importantly and more rewarding we can give clean water to the 10% of the Earths population that does not have access to clean water. You are on the right track but missing a few variables. Let me know if you have an interest in discussing .
