@@sirdeadlock Let me guess the framework grabs onto the water like zeolite (which gets toasty while doing so). You heat up the saturated dessicant to a still higher temperature, to force it to release the water in gaseous form and you condense or even freeze that water with a heat exchanger of astronomical proportions and power to condense the water (if you're going overkill on stripping all that thermal energy from that mass of steam, you might as well turn it into ice).
Sure, it will work .... when you give it a VERY LONG TIME and not allow a drop of water to evaporate from the captured water. Requires a huge nuclear powerplant or a solar/wind farm the size of France strapped to the whole system. You have to deal with the heat released by the dessicant grabbing onto the water vapor and the heat released by condensation of the released water. The whole idea is rather cack handed, but I guess desperate times require desperate measures. I would rather apply such an awkward concept to capture carbon dioxide, instead of water.
@@unf3z4nt Really now? An Israeli machine that can pull water out of the air has been sent to northern California to provide clean drinking water for US police and firefighters battling the Camp Fire. www.timesofisrael.com/israeli-machine-that-pulls-water-out-of-thin-air-sent-to-fire-plagued-california/
Its super dangerous to tell the people its drinkable, which is not true. If you do this for a longer time you will just die, i dont understand how seeker didnt pay attention to this at all
@@mumbairay That would make for a nice scammy kickstarter! 'Air from water, using bleeding edge miniaturized nuclear submarine technology this tiny electrolysis unit will allow you to dive for hours using two AA batteries'. :D :D
Water from air tech has been going on for decades, the moisture rigs in SW are just smaller vers of existing tech today, there's var water from air technologies but it still depends on there being moisture in the air and some places just don't have it at all, 0.0 ml per sq kilometer of atmosphere. In SW, below those white towers is a water tank that gets harvested when it signals the Lars home.
It's makes absolutely NO DIFFERENCE in skale of desert and even smaller difference (if this is possible) in a scale off Earth, yet it can save thousands of lives because the water is clean (not like in a rivers or pods) and make life easier to people with poor water supply. It's a great news, one of the best this year. I hope they will be able to extract more water and faster from this!!
Part of the changes to the climate is that the overall hotter air will hold more water and prevent it from precipitating as much. Especially over hotter areas of land
@@philip0320 so pure water (pure H20) basically has no impurities (minerals). In a nutshell, pure water acts like a liquid sponge, which would leech out the minerals in our body necessary for neurological and muscular functions. Water dissolves things, like how you mix a sugar cube in it until it dissapears. And the water we drink is called as mineral water, because it contains safe impurities which reduces the tendency of the water to suck out our minerals.
@@philip0320 Because the concentration of dissolved particles in your cells would be much higher than in the pure water, and the resulting osmotic pressure would actually force minerals out of your cells into the water so the concentrations equalize. No bueno
@@gearhead1302 He did a few videos on the whole concept. To paraphrase, moisture farms need to account for the large amount of heat required to be taken out of water vapor in order to condense it to a liquid, from air carrying little to no water vapor.
@@gearhead1302 Yes, he did a video on this exact project's earlier prototype, two years ago: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EGTRX6pZSns.html
I disagree. I've been wondering since childhood why we couldn't pull water out of air, because of the similar molecular composition. I especially wonder why California wasn't on this problem way sooner. It took so long to figure this out that Elon Musk probably would've done it eventually out of impatience.
actually unlike other shit that came before when MOFs absorb water they release it when Energy is applied to them in the form of sunlight so are putting the energy into the system to condense the water. its a solar powered water condenser
75 years later "The earths weather patterns appear to have been altered to the point of collapse due to the massive installations of ozone distilleries in major nations."
well decreasing the amount of water vapour in the air might help with global warming we just gotta make sure we don't take it too far or else it might get too cold I guess
@@abdelrahmana.abdelgawad6635 EXACTLY!!! Water vapor is the most potent greenhouse gas. They now believe Venus had oceans for billions of years. Then a large amount of CO2 was released which created a runaway greenhouse effect. Basically more evaporation=extra heat trapped. Next thing you know the oceans are trapped in the atmosphere making Venus 91 atmospheres at the surface and over 450 degrees.
There is nothing to debunk. They already said that unassisted and with zero power the device can only produce 200 ml of water day for 1 kg of MOF (they never mentioned the volume or density of the substance ). That isn't an impressive amount , though it does seem more efficient than the previous methods .
It's called an atmospheric water generator, it's a technnology that existed for a while now...I had some at my school in the form of water dispensers, the water tasted weird though.
@@brandonporter6223 they do not, and cannot, work well enough to be worth while in the desert environment. There is a limit to the amount of water you can extract from air. In a desert, that's low. Like not enough for any human to survive off of in any capacity.
Yes , at 95-100% humidity rain kinda does the trick..not to speak of the huge amount of power that they need to produce useful volumes (even at these conditions). Both of these requirements are absent in the setting (dry and semiarid deserts)in which they are trying to “sell” this product. The dehumidifier is a great invention, but it’s no law-breaker, so these “magical re-inventions” all end up in the same place.
The desert air isn’t really being dehumidified because such a small amount of water (relatively speaking) is being pulled out. A dehumidifier is for small enclosed spaces where there’s a chance of actually decreasing the amount of moisture in the air.
@@ThatOneScienceGuy what would you call this then? I don't know what else you would call a material that adsorbs water from the air other than a 'dessicant dehumidifier' .
jacob smith We can call it a moisture condensation machine. Because that term would focus on the product (water) rather than the effect (dehumidify). I just felt like dehumidifier wasn’t a good term because it’s describing what’s happening in the airspace. And since the desert air isn’t going to experience a measurable drop in humidity, calling it a dehumidifier didn’t seem precise enough. I hope you can see what I mean. Maybe I’m wrong. 🤷🏼♂️
Dry areas seems to beget moisture. Dry air draws moisture in from wetter regions. Wetter regions becoming dry causes more water to evaporate. It is not like it would cause a global disaster. If it were truly bad people in winter or deserts would die from chronically chapped skin, not dehydration. The only area that I might be concerned about would be the Atacama as that desert is locked due to climate inversion. That area would make for an interesting case study. It is raised where something like Death Valley is below see level. The North African deserts were created from the land rising but I doubt they have problems pulling moisture in for a minimum amount of relative humidity. But what do I know?
Charon C. Before you call someone an idiot how about you do some research yourself? Do you really think an aluminum box is going to dry out 1000s of miles of air, and that evaporation is just going to stop all of a sudden? Go back to school kid.
@@lordx4641 i was always under the assumption that water vapour in the air was necessary for us to breathe properly as it moistens the airways as we breathe in and out, wouldnt the air be dry and rough to breath without the water vapour there?
@@hfjtrytry9216 yes u r right moisture is important infact without moisturised air there won't be any rain and aswell plants will die out just because some country miles away did large scale water extraction from the air it will influence the global climate for sure this time nd in worst possible case unfortuantely u cannot underestimate human innovation when it comes to destruction but I would be more pleased if we could someone filter sea water but I still doubt sea can fullfil human greed even if I hand over this cosmos their greed won't be filled
Incorrect the air we breath contains the necessary ingredients needed for moisture. The thing with a desert is that its too dry for moisture to actually be created usually. The machine is able to get around this creating water from that air. Essentially the Water traps and Moisture Vaporators from DUNE and star wars respectively.
@@Quetzalcoatl_Feathered_Serpent it converts water from air by extracting that tiny percentage of moisture from air. And the desert air can hold easily moisture but because of climatic patterns it cannot for eg their is a rain shadow region to such extent that rain doesn't occur there then it won't rain bcuz air is not moisturised air picks up moisture even dry air has but very little
Yeah its called dehumidifier. And guess what? It works only in humid areas.... Which dont have water problem. Dissapointed that you would report this...
@@KrKrp0n3 And I wonder how many papers the entire team on this channel have published in science journals compared to Thunderf00t? Perhaps you should stick to listening to music if you think making RU-vid videos is science. The information found on this channel is not the most reliable.
@@attilathenun It's Thunderf00t's moronic fanbase. What did you expect? They only read the video title without actually watching the video and are already calling this debunked. lmao.
@@Teddylandclub Doesn't matter how well or how little energy you need to put into a system to extract water from the environment.... It still doesn't take into account that places where water is scarce, there is a lot less water in the air so less to extract. Literally, the only environment these water extraction machines are good in is ones that don't need it or it would still be cheaper to just Truck In fresh water from somewhere it is abundant. The problem you have here, is people that have never watched a Thunderf00t video and understood what he is saying and is just being some dufus on the internet trying to be the edgy counter argument.
The Xiarthos I watched the video, and found it to be lacking on details. No mention of what the relative humidity was when the test was connected, or exactly how the water was harvested once it was, “collected” by said materials. I’m hopeful it works as good as they seem to make it out in this video, but, like everything else that sounds too good to be true...well, I guess we’ll just have to wait to see.
Oh hey look someone's wrong on the internet. Did thunderf00t teach you that being a skeptic meant not watching videos and leaping to assumptions? Dgmw, he was right about using standard dehumidifiers but tell me how this is the same thing, and ill tell you how you're wrong using only info i got from actually watching the video. Lets rumba, spooky.
You can turn Lead into gold too -.- It will just cost much more than market price of gold... It is funny that you are not talking about price of this tech. I'm 100% positive it would be cheaper to bring water in cisterns...
It's all fun and games until you scale this up and realize the annual rainfall is no longer 25cm or nearby micro climates begin to show signs of interference from artificial condensation. Imagine we extracted all the available Oxygen from the spaces between water molecules..the fish would die because that's what they breathe. What else survives on that moisture in desert climates..guess we'll find out ! =P
This is using water in Air , not air itself. And there is set amount of water vapor. They would need some extreme turbines to move millions of m3 of air to get few hundred litters of water , and if they lets say get 50% of water,another 50% will need 4 times more energy to get out , and last 25% will need 8 times more , last 12,5 % will need 16 times more.... At certain point it would be cheaper to lunch water with spaceX than make it on desert...
Relax, if there's one thing industrialization has taught us it's that no amount of monkeying with the environment will ever cause a problem for us, as humans, here on Earth. (Chanting.....,"Manifest Destiny, Manifest Destiny, Manife.....) /s
Plus water vapour accounts for around 3/4 of the greenhouse effect so lowering the amount of water vapour would also reduce temperatures(though only by a small amount with the tiny percentage of total water in the atmosphere being removed). Would be interesting to see if the can scale it up enough to keep dams full in places like California and Australia where poor planning and rapid growth has led to yearly water restrictions.
I doubt this could cause dramatic climate crissies, but the Atacama would be an interesting case study. Dry areas seems to beget moisture. Dry air draws moisture in from wetter regions. Wetter regions becoming dry causes more water to evaporate. It is not like it would cause a global disaster.

This is been possible for decades. They’re called dehumidifiers and it is not an efficient way to obtain water. Regardless of the technique, you can’t get around the Thermo dynamics of condensing water from the air. This is something that anyone has taken an undergraduate chemistry course knows immediately.
People be talking about Thunderf00t, but I think his videos were pointing out the law of conservation of energy, and how condensation of water by thermal/cooling means is rather impractical. When he debunked the last iteration of MOF technology in his video, he said that it looked like a peltier device, and then debunked peltier device-based water condensation (which is infeasible, as he has pointed out multiple times). This device seems to be taking a different approach than condensation by cooling. It seems to simply gather water vapor out of the air. This gathering allows the water to have a saturation which would allow for condensation (because water can exist in liquid form at room temperature). So, assuming MOF technology is capable of this gathering of water molecules, the approach is able to bypass the energy requirements that are normally required of condensation by cooling. The input of energy from the sun could be the necessary energy to carry on this process, and seems plausible (especially considering passive processes like the drinking bird, or water transportation in xylems). Given that we have 1 PhD against (Thunderf00t, who didn't address this MOF idea), but multiple PhDs in support of this technology (Univeristy of Berkley and MIT, in addition to peer review), I will place my bets on the greater collection of PhDs until more compelling evidence proves otherwise.
I was a freshman in community College about idk 12 years ago or so and one of my teachers told the class about this. He was like it could change everything because now wars will have and endless supply of water on tap
Exactly that is a really bad idea because in certain dry areas the water will accumulate in areas with low pressure. People should know don't mess with cycles because you will probably disrupt it and you will break the system. Why can't they just use desalinated water. That will not interfere as much with weather system. At least the place is not getting drier probably wetter.
@@user-pg5re1cg7d because most of these desert regions are thousands of miles away from the ocean. The cost of desalination is also pretty high on large scales.
@@MrObveous777 most people that life in a desert life in close proximity to the ocean. I don't know what would be more expensive this or desalination plant by the cost per liter.
Akia Athallah I don’t really know for sure but I think it would not have much of an effect because all the water captured would eventually evaporate back into the atmosphere of the region after being consumed. (E.g. through urine and sweat.) Animals are basically walking water bags, yes, but it is not permanently retained as it might in an airtight container-they cycle water like a water filter through their organs and release the rest as waste, the non-solid parts which then evaporate. There are also technologies to purify the waste water of a toilet on location in a small unit. Less new water would need to be used if that were also implemented.
What takes no energy to collect takes energy to release. So how does the math check out with releasing the water efficiently in terms of energy expendituure?
That sounds awesome that they can make water like that hopefully it's safe to drink and it would be even better if they could make a desert into an oasis
And there is a reason that sensible people don't use them as a water source. Especially in environments where there is very little moisture in the air anyway.
Whenever theres a weird scientific breakthrough thats barely gaining any traction except on “science” based channels and always have the “here’s how” at the end, expect it to be complete dog shit and never see the light of day
You wouldnt want it to anyway. This is yet more short sighted nonsense from ego stroking researchers looking to rush to fame. If our species actually relied on this to maintain our consumption of water, and with current growth rates, we would alter the entire weather pattern of the planet by sucking so much moisture out of it.
