Water from the air (2). Homemade atmospheric water generator (AWG) 

Did you say your design wasn’t perfect? Mr. Humble, it’s better than nothing. Each drop counts. ❤️

Hi, thanks for sharing. Using the TEC is a brilliant idea. Increasing the surface area, again is a great idea and perhaps you might try the copper scrub pads made for cleaning the tips of soldering irons. However, my opinion is that your design geometry demonstrates too much of a focus on cooling the copper. Remember, hot air plus cold copper plus airflow will give you the best results. Start by picking an amount of water you wish to make (say 1 liter) then calculate how much air that will take and you will know your required airflow (cubic feet or meters per minute/your timeframe). It is fine to place the fan above the TEC pointed at the TEC so the hot air rising off the TEC travels back past the TEC and surrounds (envelops) the cold copper. The TEC does not care which direction the hot air it radiates flows as long as that hot air on the surface of the TEC is being swept away (using a heat sink is fine still). When that warm/hot air flows around the copper water should condense and drip down and that air can be directed through a coiled copper pipe forming a tunnel |||| -> where the air being drawn in by the fan can take advantage of the heat still it that air just used (a heat exchanger). So from top-down, copper coil pipe tunnel (with a leg dropping down connected airtight to the catch container below the bottom of the copper pad but above the waterline) and a leg sticking up and out away so the air exiting does not get drawn back in by the fan). Under that goes the air draw-in tunnel (heat exchanger) a fan blowing down into a heatsink connected to the hot side of the TEC, a solid copper plate the same size as the TEC on the cool side (a pure copper heatsink shim would be perfect) which connected to that would be the solder iron scrub pad or copper shaving slightly copper plated to hold those shavings solid (any high surface area copper geometry). Finally the drip container, air sealed at the level of the bottom of the fan. An outlet at the bottom for water to drip out but not so big as to let the warm air out. And the heat exchanger air outlet, where the warm air exits the drip container, above the water line but below the bottom of the high surface area copper.

Great societies are made by people like yourself.. you're a gift, a good son & welcomed blessing to any family that's previlaged to have you!!

That is a lot of thermal paste, you only need a "very" thin layer less than 1mm, the thinner it is, the more efficient it is. Instead of covering the hole surface, just apply the paste in lines horizontally, about 1cm apart. When the sink is attached, it will spread the paste over the surface very thinly.

Finally, actual fresh water.

This is exactly the kind of content I have been looking for! Thanks :)

Mr. Yazdan, your work is awesome. I dont consider it failed as you kind of mentioned at the end of the video. It worked, because we it produced some output regardless how much was it. We can get the idea and make it better. Thanks for sharing your experience and knowledge. Please keep going and sharing. I went ahead and hit that Subs button and thumps up one as well :)

Thank you for your work! Wonderful! As someone who's hiked in fog-covered redwood forests, I've experienced first-hand the rain they self-generate. I think the physical model of the Sequoia Sempervirens branches and branchlets is excellent structure for water harvesting... I wonder if the copper collector could be modeled after them?

Good start. Please keep working on it.

This would work great with older, second hand solar panels. Especially the 12v/18voc that could be directly wired into the fan and Peltier plate. You could run 2 TEC-12706 off a 300W solar panel quite easily on most days.

Thank you Mr. Yazdan. You and many like you give me hope.

Great experiment my brother! Thank you for sharing! Stay safe and keep having fun!

Thank you!

A second regular heatsink on the cold side would probably be the most efficient for water-harvesting. I like the idea of sucking the air first through the cold sink, then using the same (drier) air to cool the hot-sink. Of course it does start to get more expensive in hardware as you scale up, but with one small panel for the fans and one larger for the Peltier, you should see very good results - probably more than enough to provide drinking water for a single person indefinitely.

Great effort. Perhaps the copper should be moulded so that it collects the water a bit better, perhaps with a micro drainage system? Love the creativity 👌

I'd like to see water condensers installed along with geothermal systems for homes. Ideally, they should need no electricity, or only an electric fan (or air circulator).

Great work. The only issue I see is that you have very less surface area. Try something like what's on the bsckside of a window ac. Lots of fins. That grill type thing.

Just like Funtus , good job man!

Good job افرین بر شما

I am kicking around similar jdeas, using peltier modules (specialized TEG modules) vs cooling system from small personal refrigerator. Peltier are horribly efficient vs rankine cycle that is magnitudes more efficient. Peltier are solid state, no moving parts. Ranking has a rotating compressor. The biggest issue that needs to be overcome is surface area. For a peltier module, if the heat and cold sinks surface area can be increased several magnitudes, you may not need fans. I think this can be accomplished using finned-tubing from a condenser coil of an air conditioner.. Most will be aluminum, some will be copper. Important note here: there needs to be a flat surface, as flat as it can be. Probably will need to b e flattened, then filed. This modified tubing can be used on both sides. There needs to be a TIGHT mechanical bond between heat / cold sink and peltier plates. Thermal paste is used very sparingly to fill in surface imperfections. Excessively thick layer can impede transfer of heat. You should incorporate some form of thermal control. 1 such control is critical on peltier hot side. If it gets too hot, it will self destruct. For the cold sink, you just need to get temperature down below dew point temperature. Any colder just makes cold water, and is a waste of energy. At a basic level, a snapdisc designed for 75 - 100C will work for hot side, depending on ambient. At time of this comment, overnight dew points during heat wave in Texas is in low to mid 80s (°F). Anything lower, you are wasting energy. With that in mind, I would not be surprised if peltier could be operated at full voltage, but then a lower voltage used to maintain based on air flow across cold sink. Picture this: an AC voltage is applied through a diode, then applied to a bridge rectifier, then to peltier. Turn on supply, peltier gets half voltage as diode is blocking half of wave form. Short the diode, and peltier now gets full voltage, less voltage drops from diode and bridge rectifiers. A snapdisc can be used to short diode out when needed. I have other ideas on how to approach, but will do own testing first. Maybe patentable and slightly profitable.

Interesting ideas. In your first video (using the stainless steel cylinder/toilet brush holed) you used a fan to force the fresh, water laden air through the copper pipe. In this video, I don't see how the air is being drawn over the copper plate - it seems to be fully enclosed in a plastic bottle, so the air is not being replaced by fresh, water laden air. I understand that the fan is only used to cool the hot elements of the system. Am I missing something?

combine your original design with the upgraded thermos cooling device, your results will be way better, you still require the fan pulling in air, you could make a device whereby the heated area can heat the air coming in making it more efficient, as you need warm air anyway to increase condensation

Thank you. I was thinking of a large coffee stainless steel thermos .

greetings! is there a version 3, or was this project abandond almost 4 years ago?

عالی بود دکتر 👍

I’m not sure but probably you already know the “Warka Tower project” that is currently experimented in Ethiopia

this is cool maybe a copper tube that seems promising

I wonder if a large barel full of plants could share some of it's space for a copper coil? Would that insulate enough? Maybe if the outside of the pot is covered in protective leaves, or that new "whitest paint" that is so white, it lowers the temperature of the surface it covers?

I don’t know about this but pls make aero gel. Saw it on Nile red and it looks pretty cool. it would be awesome to see it here

how about use a long copper CPU heatsink on the other side for more surface area (in place of that copper plating), where the fins are vertical so the water can drop down. Perhaps have some type of wicking material (cotton wool?) at the bottom so the captured water doesn't evaporate too much.

Great video! What's the silver block called? (this is all new to me). Also, should I have two solar panels? one for the copper plate and one for the fan? (how do you increase the voltage?) Thank you!

بسیار بسیار مفید

The surface contact between the metal scrubber and the copper plate could be improved if you added thermal past in between.

Could you use the hot side to increase the humidity by heating water before it goes into the condenser

Next year I am going to build an off grid living research facility in the desert. I plan to have one person on site year round. My first concern is water supply, for now we will haul in water but if I can suppliment the supply at least a little it will help.

The idea to use steel wool to increase the surface was clever, it made me wonder if copper wool is also a thing and one Google search later, it is.

Hi! I have a question. The fan with heatsink that I got has red, black, and yellow wires with a 3-pin connector. How would I power this? Do I have to worry about the yellow wire, or can I just hook up the red and black wires to a dc power source?

❤

hi !! can you pliz write the name of all things that u used and thank u for this amazing video!

The secret is to get a great temp difference between the hot and cold sides. Try to put a separator medium, like a cloth, between hot and cold sides in a squire container made of zinc plate. This zinc container should be open on both sides. Put a plastic container with small holes in bottom, filled with water, on top of the container, on the cold side ,

omg i just had this idea i went to youtube to see if someone made if :D

Water should drip down on cloth. Put hot side in sun with bigger fan blowing through. Paint also black. but keep cold side under shade, wrapped in cloth and wettened with same water container. better to use more units next to each other without a separation.

the air must flow from hot side to cold site for condensation.... it will work better if you reverse a fan

Hi! Is it possible to turn a peltier dehumidifier into an atmospheric water generator? 🤣 I just opened my dehumidifier up today and the mechanism is similar to this except instead of the copper plate it’s an aluminium heatsink...I’m so tempted to try drinking the water 👀 ok anyway so the question is how do we make the water from a dehumidifier safe to drink?! 🤣

Please tell me name of this equipment and what is the principle of this

Making water from air is important for hypersonic air planes design

A capacitor connected to the solar system for the power issue, simple refrigerator controller with senior to keep peltier from overheating - maintain ideal temperature range for condensation to form. Try using a metal sealed water bottle with some water as the cold sink and just let the hot sink breathe free to help the peltier work easier. The liquid in the bottle will freeze or get close to it and condensation will form on the outside of the water bottle and collect itself as it runs down the bottle. A second temp sensor and controller for the cold side could be good for conserving energy, either temp sensor could turn off the peltier. Some BTC would be awesome bc1qlkwr97sq4m4m3kmlsqh2jmyevaetwwecqk0ta2

How about a computer heat sync on the cold side?

سلام آقای یزدان ، بسیار عالی فقط من نمیدونم با این همه نیاز به آب در ایران ، چرا به فارسی اینها را توضیح ندادید ؟؟ شاید هم توضیح دادید من نمیدونم . اگه دارید لطفا لینکشو اینجا برای جوانان علاقمند به اشتراک بذارید .

You have a fan on the hot side but not the cold side. If you put the fan on the hot side with the cold side. if you connect the cold side with the hot side, then the air on the cold side cools the hot side. it's about water extraction and not cold air.

I think (on your original design) you could have increased your success using an air circulator instead of a fan. I guess it wouldn't matter for this version, since the fan doesn't direct any air into the bottle.

What is the components?

you do understand that the water in the air is clean , but your process shure isn't. steel wool against copper will just create a electrostatic reaction. This is going to break down that steel wool and put it in the water.

You got any calculation for the Idea ??

there is so much humidity here i could probably make enough water to drink for ever

How much does it cost And how can I get them Please help me I wanna make it as a project

I know those plates are problematic for your design, being that the heat side reduces the cold side - but it seems to me using energy to dissipate heat is counter productive to the equation - need to draw heat away but use it - current design is using the cold side of the plate and ambient air temperature, but the plate itself creates both hot and cold

If there was a way to run a small pump to cycle water through the copper pipe. It can be a closed system (The waters don't mix) or a demand system where it runs with the water that's in it to keep a certain level. The original prototype from an earlier video would work better with this type of design. I've been experimenting around my house and at work with blowing air over a frozen water bottle to get an idea of the amount of humidity in the room. It is a subject that has interested me since I saw a video on fog catchers. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-b8TBdrzemiM.htmlsi=3JhAq4GRg75OwFFe Or, turn it upside down so the fan pulls the cool air from below across a copper tube that has outside air around it.

Ayyy i am the first one do u remember me i am rayan

How much water per Kwh does that make? DO you know? Surely you must have made some water and know! That is if your design works and if you have made any water with it.

I cannot understand what you're saying in the 1st min. What kind of plate?

I am from India 😍❤️ I am interested in electronic projects ❤️😀 #nzhcreation but I have a question that some people are using water to make air water what is the correct logic pls reply me I want to know this 🙏🏻🙏🏻🙏🏻😭😭😭😭😓❤️❤️❤️#nzhcreation 🙏🏻🙏🏻❤️

Very "cool" (literally and figuratively!) :)

The 12V requirement is because you are using a fan and sink from a PC. A laptop fan and sink would only need 5V.

Why are we not using existing tech like ohhh idk a dehumidifier

Can I pay someone to make this for me ?

You are wasting your hot air. Dew point involves a temperature difference, cycle all or a portion of your hot air into the cold chamber and use a pulsed vibrating motor on your collection surface.

this is not practical, first you need 12V from somewhere but solar cell and perhaps 12V battery (like a UPS) may work

Cpu

You can find best solutions on Avasva .

I wouldnt recommend getting on a plane with that contraption and that accent!!!
