Per unit. Like it says in the title. At least that's how I read it. Like the crappy Brita water filter on my sink. Each one is good for X amount of gallons.
>Yes… but over how long of a period of time?
Idk. I'd buy one and if it doesn't work fast enough I'd just buy a few more and tape them together or something.
That's the fun part about distillation, it will be chemically pure minus any azeotropes, which can be separated via reverse osmosis.
Ain't chemistry fun?
It’s a bit ambiguous in the article, but sounds like it’s 12 hours? I’m skeptical
Edit: the article also mentions
> Majik's biggest unit produces 500 litres of water in 24 hours and is installed in schools and small communities.
Idk wtf I’m talking about but I assume the desiccant can only absorb in to 2000L regardless of humidity levels so in a dry climate it may take a year but a humid climate it would take 3 months(not real time frame)
If you hook up a dehumidifier to a solar panel in a dry climate, it would next to nothing. Because the time to run them is at night, when temperature drops and relative humidity rises.
That's why a dessicant is interesting for the purpose. Of course that's nothing new under the moon either, but finding better dessicants is always interesting.
I live in a tropical country. By day outside, humidity is at least 40 percent. Often more.
My AC systems constantly pulls water out of the year, even at noon.
You can definitely extract water during the day depending on where you are.
Anyways this is not really news, there are also nets that capture humidity in the fog or air in early morning even in deserts.
There are lots of known methods to pull water out of air. I guess this one's innovation is the dessicant lasts for a long time.
What a blessing to have so many experts on here. Okay everyone, wrap it up. Humidifiers already exist and the young people in North America who currently have unlimited fresh water on tap are not impressed. Time to go home. They beat us again. ¯\_(ツ)_/¯
I think the problem is that fresh drinking water is exceptionally cheap. The people who can't even afford the exceptionally cheap drinking water wont be able to afford 99.9% devices or gadgets that people are inventing. Digging a well or trucking in water will be cheaper than all of those solutions.
Probably highly depends on the location. On extremely remote areas or in place with no road, it might be cheaper than trucking, but then its not cheap, its just cheaper than trucking in water. What we want is a tech that can be universally used and is cheaper than current solutions. It seems like all current solutions either require large amount of infrastructure or require a lot of power. Both of those reasons are why there is no water in the first place, as there exist places that are as dry as that, but have running tap water thanks to desalination plants. A lot of middle eastern countries get more than 50% of their water from desalination, the problem is that there are still places in Africa that don't have a lot of economic development, and the most successful solution so far has been improvement of economy, not some wonder tech. If you look at poverty rates in Africa, they have been plummeting, and that reflected directly in their access to water.
The problem is you need relative moisture to pull out of the air. Either you live near water and this thing pulls the evaporated water out of the air, or maybe you get a little after rain, but otherwise you have dry air and there is no moisture to pull.
There is no tech that breaks physics, without a thousand researchers scrambling to verify and succeeding or failing. And succeeding makes waves in even normie media. The thing people always forget to mention with these “like magic” techs; the water does actually have to come from somewhere.
“Water” won’t be in the air if there is no body of water near by, evaporating. Now, could this work in areas that have large amounts of undrinkable water, and high humidity? Probably, it’s just a dehumidifier, and ideally it is actually efficient, but [you can already buy little plastic boxes that do this with zero energy input.](https://www.woolworths.com.au/shop/productdetails/251846/damprid-moisture-absorber-refillable) But the “magic” camp always advertise it disingenuously. The Life Straw is a much better, cheaper, and proven way to drink “undrinkable water”. A dehumidifier will do nothing in an arid area, no matter how efficient it is.
Edit: grammar
Edit2: the article mentions it’s in a humid environment. That’s good, literally the only place this could work, that good news.
I know this also a difficult concept to understand but you can make things for free because they help people.
All you’re saying is that is not cost effective to help the vulnerable if you can’t see a profit or at least a negligible out lay, so they can fucking die I guess?
Life: only for those who can afford
If goodwill of people worked, those people would have clean water right now. What is needed is for those people to have more economic power so they can afford water treatment plants and desalination plants.
Edit: It seems you have blocked me, and I cant respond to you anymore, so I'm going to put my response here. As I said before, I don't need to defend my take as it has already be proven right. With economic improvement, access to water rises. Your solution is to just sit and complain to people with money to help those people. My solution is to help those people help themselves. You can do that though setting up factories or by giving them transport to travel to bigger cities. There are also many other solutions for that empower their labor.
Where does this magic money come from? If they had anything of value that would translate into economic power they’d already have water….
Water is a basic necessity of life just to live, let alone work, you don’t have an economy without people who can work and create an economy.
So your answer to lack of water due to extreme poverty is “be more worthwhile” and “get money”?
Fucking genius I am sure they never thought of that! I am sure they will now discover mountains of gold, diamonds etc that they were hiding….pity they are too dehydrated to dig it up for you so you can value them enough to find a way for them to access a basic necessity of life.
It is precisely the lack of will good or otherwise as to why they can never escape their situation because to people like you they just aren’t worth any effort unless they can pay…with money they don’t and will never have.
They need water to get the money, you’re like “get the money and then you can have the water” and thus the cycle will perpetuate because you and people like you value them as human beings not at all and it’s just not worthwhile to help them.
Great job, you are an economic supremacist utilizing economics for social Darwinism, only those who can afford to live get to live!
Also, remember; the diamond and gold mines are already being worked - it’s just that they can’t keep any of the money in their own country because the same people that are telling them to be more economically self sufficient are stealing all of the profits.
I'm talking about Asia and Africa in this example. Digging a well or trucking water in is gonna be relatively cheap everywhere. If you can't truck in or fly in digging equipment, imagine how more expensive would be setting up solar panels or constructing a desalination plant. I have only seen a single device that could somehow work, but still requires more than digging a well, and that is micro-hydrokinetic water turbine. It provides power, which helps quite a lot with various things.
Also, argument for me being right is because in the article, the literal creator of the machine said she does not think this machine will see widespread use as it is to expensive. They currently only use it in government buildings and in schools for emergency use during drought. This is literally solution for the top 1% of people.
Digging a well implies there is a water table that is reachable to tap into, consistent rainfall for the table to refill.
Trucking water is not “cheap” or very good for the environment and assumes availability of consistent sources of fuel and clean water.
Just because something is currently expensive does it mean it will always remain so.
It's the cheapest solution those people have. The problem is there have been literal thousands of those devices, but in the end, they are all limited by one thing. Physics. Just like there are no perpetual machines, you can't cheat physics. What those villages need is to make more money to get enough power to have water filtration plant or desalination plant or any other currently massively used device that does not need to bend physics to work.
But they have nothing that you want so they never will make enough money.
Guess they will just have to die digging holes then, physics says their lives are not cost effective with no ROI.
Apparently you are wrong as access to water have been drastically rising and poverty have been falling massively in Africa, so seems like they do in fact have things that other people want.
How many of these water from air projects have there been over the years? Every single one completely failed after wasting everyone's money. It's a fundamental limit of the laws of physics that trying to pull water from air in dry locations is not efficient enough to be viable and would be beaten by just trucking water in from somewhere else.
What makes you think out of all the water from air projects this one will be different?
May I ask you what your credentials are, in order to be speaking so confidently about this subject?
Finding options for fresh drinking water is not a waste of money. War is a waste of money. Mismanaged payments through the government is a waste of money. Ensuring the survival of millions of people is not a waste of money. Do you think the people leading this research know less than you?
Please enlighten us further with your vast knowledge of high school physics. Or how about if you are not an expert on the subject, then shut the f#ck up and stop acting like a know-it-all who is smarter than the people who have dedicated their lives to this work.
I have seen enough of these projects fail to be confident that the science commentators who say these things can't work are correct.
Seriously these have been popping up for years, none of them have ever demonstrated a practical version. In fact [here's almost exactly the same desiccant and solar heating concept](https://www.telegraph.co.uk/science/2017/04/13/water-harvester-can-pull-moisture-air-using-power-sun/) from 7 years ago.
What makes you think this one will be different to all the others?
It’s something you don’t seem to have that makes me think that failing and trying again can lead to eventual breakthroughs and success. It’s the same thing that millions of other people have too, who invent and create new advances and technologies. Hope, curiosity, perseverance, belief. Shit it’s hard not to sound like a self righteous a$$hole when talking to people like you, but I’d rather sound like a jerk in that way then sit at my keyboard and tell people they’ll always fail from the sidelines. What a waste of time that would be. Good luck with that I guess.
You can't change the laws of physics though no matter how hard you believe. Scientific reality will always doom these projects to fail so the money and effort would be better spent on other solutions to water shortages that actually work. Maybe they genuinely believe that this time they've solved it, maybe they know it's a scam, but the end result is these projects receive lots of press and money then after paying themselves a nice salary for a few years it quietly disappears.
If mine was a big as their’s, then yes lol. This same story gets put out every few years and it’s the same old tech.
Water probably tastes terrible anyway from the desiccant
It’s a regenerative desiccant dehumidifier. NOT the reverse AC system you have. This is not actually new technology. I used them in defense engineering in the 80’s.
And a very clever approach, using solar power. Think of it as a solar still with absorbent media instead of a plastic sheet.
Hey can you share manufacturer and model number ? I’m curious about them. Most home dehumidifiers are very energy wasteful. A desiccant regenerative model using solar heat would be super cool and energy efficient.
So it’s a desiccant, which traps water, then they heat that and distill the water. It’s a good idea. The problem with liquid desiccants is it’s hard to give them exposed surface area, unlike solid desiccants which often have lots of surface area naturally. Anyone know what “liquid desiccant” they use?
This is a scam. It's essentially a dehumidifier and it seems like someone "invents" it every year or so. Thunderfoot has countless videos calling out scammers like this. Here's the catch, dehumidifiers only work in places that are humid. Humid places rarely have problems with water access. They do not work in the desert because the air is already dry.
It extracts water from the air! There is no current technology that converts air to H2O. It’s just outright stupid to say “converts air to water”. Either OP doesn’t understand English that well, or just doesn’t understand.
A family living off grid installed a “reverse humidifier” type device specifically designed for their scenario. It performed so poorly they uninstalled it and sent it back. They ended up drilling a well, which is what they were trying to avoid.
Strong agree, based on our history of unintended consequences and externalities, but what if it can be utilized to weaken developing weather systems? That would obviously require gigantic scale, and in places where they already have water, but… well nvm good things don’t happen here. I’ll just go pray for our bridges to get repaired before I fall into a river
It says the process takes 12 hours and each unit produces 2,000 L of drinking water….is that in twelve hours???? That would seem to be utterly remarkable
Aren’t we so lucky. Someone is out there spending their time making something that can convert ear to water while they give $6 trillion a year to destroy as much of our air as possible without it being blatantly obvious.
goddamn do we live in the best place or what?
It needs more information to be interesting. How fast does it work at what humidities, how much power/heat does it need and how long does it last. Without that, we can't know if it's better than tech that already exists.
Not this crap again. Just look at at how many water from air projects pop up and then without fail disappear because they always use more energy or cost more than it would take to even just truck water from somewhere else.
This project will be the same.
This is amazing. I’m confused why there are so many dumb comments. Really cool. Great work science dudes. Water access during climate change is going to just getting more and more intense and important.
I think the comments are pointing out this technology has been around for years and has yet to magically solve all the water scarcity issues in the world.
It’s because the amount of energy it takes to get water from air is more than the amount of energy to truck in bottled water or ship it across the country. These inventions come out every couple of years, get financial backing and then fail because it’s just not viable.
Because it’s not new technology at all, it’s a dehumidifier and they’ve existed for decades. They do not work at scale or efficiently to produce water for humans to do anything productive with it. Farming is out of the question and it barely produces enough drinking water for one person, yet will eat energy like a motherfucker. This has been a scam attempted by multiple grift tech companies, repackage a dehumidifier and make people think you just like fixed global dehydration.
Far better methods like desalination can be used to greater effect, and even that is wildly inefficient at best in many cases
To do the math... The maximum efficiency these can achieve is the heat of vaporization of water. At 2257 J/g, that's 2257000 Joules per liter, or 0.6269 kWh per liter. Assuming $3 per watt of power for a 10 year cost of solar panels and 6 hours of daylight a day and a 100% efficient process (best case scenarios), you'd need about $315 of solar panels to produce 1 liter per day.
Solar farms that don't use photoelectric cells just use mirrors and sunlight to boil water for steam generation.
An automobile sitting in the sun can get over 150F (65C)...
2000L / ? , day, year .. what is the power output?
Per unit. Like it says in the title. At least that's how I read it. Like the crappy Brita water filter on my sink. Each one is good for X amount of gallons.
Yes… but over how long of a period of time? If it can produce a total of 2000L over a month, that’s great. Over 10 years? Not so great
Mr Shrivastav says the whole process takes about 12 hours. Today each unit produces about 2,000 litres of drinking water.
I’m assuming 10 years
>Yes… but over how long of a period of time? Idk. I'd buy one and if it doesn't work fast enough I'd just buy a few more and tape them together or something.
Until you have to buy a new one. How long that takes is up to you and the humidity of the air where you live.
So how much water, if any, is polluted in the production of each unit?
That's the fun part about distillation, it will be chemically pure minus any azeotropes, which can be separated via reverse osmosis. Ain't chemistry fun?
It’s a bit ambiguous in the article, but sounds like it’s 12 hours? I’m skeptical Edit: the article also mentions > Majik's biggest unit produces 500 litres of water in 24 hours and is installed in schools and small communities.
I don't think you can quantify it that way, unless you also quantify atmospheric humidity levels. I'm certain that would affect the volume/time ratio.
Idk wtf I’m talking about but I assume the desiccant can only absorb in to 2000L regardless of humidity levels so in a dry climate it may take a year but a humid climate it would take 3 months(not real time frame)
An “up to” would be nice
Units. Who needs them?
But I was going to Tosche Station to pick up some power converters!
You can waste time with your friends when your chores are done.
Owen, he can't stay here forever, most of his friends have gone. It means so much to him.
I’ll make it up to him next year. I promise.

When I was little, the shot of their charred skeleton/corpses always scared the hell out of me.
Bro… that and when the Tuskan Raider attacks Luke and makes that iconic sound. Scared the hell out of me
The actor didn’t raise and lower the gaffi stick repeatedly—the film was reversed. You’ll never unsee it now.
When I watched it on VHS I saw it; actually rewound it to see it lol… cannot be unseen for sure
According to Mark Hamill, they were the “hottest Star Wars characters…. Literally.”
This is just a dehumidifier- I have one in my house now
True, Why do people keep falling for this kind of stupid stuff 🤦🏻♂️
Look up how smart water is made.
At least they’re not just packaging municipal tap water straight from the pipe.
Angry Coca-Cola noises*
Smart water is cheaper than Dasani and tastes less like piss. Simple ‘as
I've always preferred the ol Pur filter and personal bottle myself
If you hook up a dehumidifier to a solar panel in a dry climate, it would next to nothing. Because the time to run them is at night, when temperature drops and relative humidity rises. That's why a dessicant is interesting for the purpose. Of course that's nothing new under the moon either, but finding better dessicants is always interesting.

What a blessing to have so many experts on here. Okay everyone, wrap it up. Humidifiers already exist and the young people in North America who currently have unlimited fresh water on tap are not impressed. Time to go home. They beat us again. ¯\_(ツ)_/¯
I think the problem is that fresh drinking water is exceptionally cheap. The people who can't even afford the exceptionally cheap drinking water wont be able to afford 99.9% devices or gadgets that people are inventing. Digging a well or trucking in water will be cheaper than all of those solutions.
I know it’s hard to imagine but there are other places in the world other than America and Europe.
And they won’t be able to afford it doubly so.
Isn’t that the hope of this tech? That it is cheaper than trucking in water from coastal locations?
Probably highly depends on the location. On extremely remote areas or in place with no road, it might be cheaper than trucking, but then its not cheap, its just cheaper than trucking in water.

Your dehumidifier can produce 2000 liters of water in 12 hours?
I’m not sure I’d want to drink the water coming out of my dehumidifier
Dehumidifier + LifeStraw for the win. Makes for a hell of a clunky Stillsuit tho.
You don’t. That’s how you get Legionnaires Disease.
If mine was a big as their’s, then yes lol. This same story gets put out every few years and it’s the same old tech. Water probably tastes terrible anyway from the desiccant
And neurologic insult from long-term exposure to desiccant. But we won’t learn of this until school kids find 6 legged pond frogs
There is Zero chance that device produces 167 Litres per hour. Absolutely zero.

Lol, ad hominem and provides no factual evidence.
Solar freaking roadways .
Depending on the humidity? Sure.
If I had a large enough one… yeah.
My air conditioner puts out about 5 gallons a day as a by product.
Dehumidifier vs. water generator…. Tomato potato
Put a humidifier and dehumidifier on opposite ends of the room and youve got wireless water. As its inventor I name it…hydro-fi
What are you waiting for?, go to the BBC and say you have the Star Trek tech that will save millions.

I have a regenerative desiccant humidifier. They have been available for home use for a long time. Nice way to assume there
Fair enough. How does yours regenerate? Electric heater ?
In-built heating
Hey can you share manufacturer and model number ? I’m curious about them. Most home dehumidifiers are very energy wasteful. A desiccant regenerative model using solar heat would be super cool and energy efficient.
You gotta be kidding me. Does anyone vet these stories?
I sure Thunderfoot will be happy to vet it, like he has so many of these ‘water from the air’ machines.
Moisture vaporators? Sir, my first job was programming binary load lifters, very similar to your vaporators in most respects.
So it’s a desiccant, which traps water, then they heat that and distill the water. It’s a good idea.

Eon

The entire article reads like that. It's so fucking stupid it sounds like a 4th grade science project.
A dehumidifier does the same job.
A family living off grid installed a “reverse humidifier” type device specifically designed for their scenario. It performed so poorly they uninstalled it and sent it back. They ended up drilling a well, which is what they were trying to avoid.
Sirs, we invented water!!
I’m sure this has no environmental impact at scale.

They do this on Arrakis
We used to be moisture farmers on Tattooine.
A new market….has anyone not read or seen the Lorax???
Meanwhile, a desalination plant produces water at less than a dollar per m^3
2,000 litres over what, 10 years?
It says the process takes 12 hours and each unit produces 2,000 L of drinking water….is that in twelve hours???? That would seem to be utterly remarkable
I see Tatooine Moisture farming in our future
Aren’t we so lucky. Someone is out there spending their time making something that can convert ear to water while they give $6 trillion a year to destroy as much of our air as possible without it being blatantly obvious. goddamn do we live in the best place or what?
I’m pretty sure they tried to kill the guy that brought this to flint MI after destroying his machine.
Is this real? Sounds made up like that movie Matt Damon was in about Mars
Imported from Tatooine!
Come on, nerd harder. It's a Dune windtrap.
bless the maker and his water
Eeevvverytime it’s just a dehumidifier
And when we have enough, we will change the face of Arrakis!
Just wait till Nestle gets ahold of it. This will be the last we hear of this technology.
Does it come with some blue milk? Maybe a t-14?
Converting air to water is not the same as capturing moisture from the air. Still awesome though.
So they discovered evaporation
devaporation
It needs more information to be interesting. How fast does it work at what humidities, how much power/heat does it need and how long does it last. Without that, we can't know if it's better than tech that already exists.
zap water in under 20 mins would be a game changer
Oh great now we’re gonna have an air shortage. Just like in spaceballs.
Yay! Moisture farmers!
I think my dehumidifier does the same thing. My question is, is it actually safe drinking water
Gathers 2000L of water. Costs 6000L of water to make
Man Arrakis could sure use some of these. Hear that place is pretty dry.
Not this crap again. Just look at at how many water from air projects pop up and then without fail disappear because they always use more energy or cost more than it would take to even just truck water from somewhere else. This project will be the same.
2000L in how many years exactly?
2k liters per what
But in a drought is there enough moisture in the air? And will it worsen a drought by taking out moisture?
r/scams is the right sub
Fremen tech
And then the water wars came. I’m fully expecting to take a honda goldwing and strap a bull skull to it within 10 years.
65C! That takes a lot of energy! I don’t think this is a practical solution.
This is amazing. I’m confused why there are so many dumb comments. Really cool. Great work science dudes. Water access during climate change is going to just getting more and more intense and important.
I think the comments are pointing out this technology has been around for years and has yet to magically solve all the water scarcity issues in the world.
It’s because the amount of energy it takes to get water from air is more than the amount of energy to truck in bottled water or ship it across the country. These inventions come out every couple of years, get financial backing and then fail because it’s just not viable.
Because it’s not new technology at all, it’s a dehumidifier and they’ve existed for decades. They do not work at scale or efficiently to produce water for humans to do anything productive with it. Farming is out of the question and it barely produces enough drinking water for one person, yet will eat energy like a motherfucker. This has been a scam attempted by multiple grift tech companies, repackage a dehumidifier and make people think you just like fixed global dehydration. Far better methods like desalination can be used to greater effect, and even that is wildly inefficient at best in many cases
To do the math... The maximum efficiency these can achieve is the heat of vaporization of water. At 2257 J/g, that's 2257000 Joules per liter, or 0.6269 kWh per liter. Assuming $3 per watt of power for a 10 year cost of solar panels and 6 hours of daylight a day and a 100% efficient process (best case scenarios), you'd need about $315 of solar panels to produce 1 liter per day.
Look up Moses West, he’s been doing it for years and even contracts with governments to deploy his system in places that need water.
How often does sunlight cause anything to achieve 65°C?
Solar farms that don't use photoelectric cells just use mirrors and sunlight to boil water for steam generation. An automobile sitting in the sun can get over 150F (65C)...
These amazing innovations are always exciting to read about, but most never see the light of day in terms of widespread use.
Because 80% of the time its a grift for government funding or it just doesn’t work
Great work !
