The system can function in air with 20% humidity or less. But these 1,000 liter a day machines are not small, at around shipping container size.
Here’s a back-up, science paper on MOF from Nature with measured numbers. 8 liters per KG per day isn’t 1000 gallons until you get to 2 tons … but it’s about 200 liters per out of 25 KG … easily carried.

"The effects of temperature, relative humidity, and powder bed thickness on the adsorption-desorption process are explored for achieving optimal operational parameters. We found that Zr-MOF-808 can produce up to 8.66 LH2O kg−1MOF day−1, an extraordinary finding that outperforms any previously reported values for MOF-based systems… "
I’m always extremely skeptical of stuff like this
As you should be
Until the device is deployed in at least a few real live locations
sorry but isn’t that just a good dehumidifier? Is there something new?
And how much power does it use?
This thing works self-contained and off grid - using materials that have huge surfaces to condense the water. It is mentioned that there are powered versions too, but the principle itself does not need extra power, the Sun drives the condensation.
Cool!
Sun: no more free power for you click
Every living thing as eternal darkness consumes us: AAAAAAAHHHHHHHHHHHH
That’s still embodied energy, so the question becomes; “How much energy does it take to actually make these materials?”
In particular, the device is packed with Metal-Organic Frameworks (MOFs), which are synthetic porous materials engineered at the molecular level to have huge surface areas. A few grams of an MOF can have a surface area equivalent to a football arena, according to the source.
That sounds pretty energy-intensive to me.
This guy got his Nobel prize for molecular sponges that can bind and release water.
Yaghi’s mechanism can do this without a power source. It uses the wind and air for water input, then the sun to drive condensation and evaporative action.
Really interesting. This could totally transform many places on Earth.

We need to harness Desert Power!
Came here to say this but knew in my heart that it had already been brought in.
Finally, I can achieve my dreams of becoming a moisture farmer.
Peaceful living as a smoldering skeleton
Where’s my blue milk?
Tosche station
Hope you enjoy a whiny nephew
What
You know the kid with the unhealthy obsession with womp rats
His name is Wormie.
Little psychopath just bull’s-eyeing 'em all day long in his T-16
In Star Wars, Luke Skywalker was raised by Anakin’s step brother, Owen Lars, who was a moisture farmer on Tatooine. That made him Luke’s step uncle. We’re all referencing Star Wars quotes.
He gets it from his father
I swear to god if that kid brings up the academy one more time, just kill me
But crying about not getting to go to Tashii station is okay?
power converters over there are pretty mediocre anyway
Shut the FUCK up we have a shed literally full of power converters, your friends are absolute trash anyway and come on what kind of name even is “Biggs Darklighter” it sounds like his parents were from a Flash Gordon ripoff
Not the power converters we were looking for. https://www.youtube.com/watch?v=rpUkokRx3-k
That water was in its way to somewhere, though. What is that other area gonna look like now that this device intercepts the water?
Eventually all that dry air will end up above the ocean and absorb more water to balance the system. I don’t think it’s really an issue, we weren’t getting rain clouds from the Sahara anyway.
Sounds like that other area needs to pull up on those bootstraps and make a water machine for its needs then.
This comment is brought to you by the sigma water machine, buy yours today and lock your grindset on hydration!
(Hopefully obvious but /s)
Are you on the Temu or the Amazon so that I can get some good boot straps and choke myself to ejaculation?
Dooooom
Someone is going to drink it then sweat it back into the air. I doubt its going to get bottled and shipped somewhere else.
same could be said about every shower you take and every toilet you flush
🎶And every bond you break, every step you take
I’ll be watching you!!🎵
They won’t probably export the water to europe or something.
I mean it’s not Nestle.
shipping container size
That’s far smaller than I expected. I also don’t imagine it will be cheap. If they manage to make it less than $100,000 then I’ll be baffled. Less than $500,000 and I’ll be excited for the possibilities in my lifetime.
$500,001
“booooring”
Considering the amount of water it ptoduces, I imagine it would be a community rather than an individual that buys it.
Frankly, I was imagining ultra-wealthy preppers. 1000 liters is less than the average household uses per day in the US, according to the most commonly repeated stat. That feels wildly inflated, but I have nothing to dispute it with other than my own household usage, which is far lower.
Yea it seems like a lot! But I assume it would be for communities that are already in the desert, they’re manageing with water, but barely, and one or two of these machines would help rounding things.

And sippin’ blue milk.Not a drop to split
Not a drop to SPIT
WTF, it was right there!!
cmon…
Don’t let Sam Altman know about this, his data centers about to have some upgrades /s
When I looked at condensers in the past, they weren’t incredibly energy-efficient. I suspect that it’s cheaper in the long run to do desalination and build a pipeline to wherever inland you want freshwater, unless you have very limited-in-scale need.
This (seemingly) solves some issues in places like Africa where warlords block or destroy delivery systems to remote villages. Also fixes disaster recovery where pipes are destroyed or water systems are contaminated
Dewcatchers, dewcatchers everywhere…
Yet again, nobody seems to be giving a thought what this means to organisms that are living in the desert. This water is necessary for life and we’re taking it.
You can’t really consume water especially if you take it out of the air. Worst case you temporarily barrow it till it evaporates again it’s not like the water is suddenly gonna be pumped out to the ocean or something.
Do you think they are condensing 1000L of water to then just splash it on the ground where it was farmed? That water is going to people (or more likely companies) that are going to leave the ecosystem.
Yes, they are going to fly away in a penis shaped rocket with all the water on board.
Well the damage is done and now we need that water.
If you plan on drinking the water, or cooking with the water, it’s going right back into the air after you pee or sweat and the water evaporates. Literally no damage done.
You cannot make the water actually disappear unless you use it in some kind of chemical reaction, and even then it may end up returning to water eventually.
…Science?
A WITCH! A WITCH!
BURN THE WITCH!
I would think that ripping 1000L of water out of an environment in a day is going to have more immediate impacts than you eventually pissing on a cactus is going to fix…
Sure, the water isn’t “destroyed”, but it is being removed from an ecosystem that has evolved to use every last bit of water it can find to survive. It may not be immediately obvious, but it sounds just as damaging as removing 1000L of water a day from a lake and thinking the ecosystem will be fine because you’re going to sweat next to the dry lakebed.

Well… It all depends on what you do with the water. Are you sequestering it in some way or are you releasing it? I mean, if the community drank 1000 liters of water, then their next piss is 100% going to fix it. Even watering crops is just releasing the water.

Again, if you’re going to sweat 1000 liters, then go for it, I fully endorse this plan. Use as much water as you want, it’s fine unless you’re shipping it out.
As someone who has thought about it, could you provide the data that you used to come to the conclusion that the amount of water being extracted from the air has any appreciable effect on local life?
From my thinking…
Death Valley covers 7800km^2.. Atmospheric moisture is typically contained in the first 10km of air. So there is somewhere around 2.5 quadrillion cubic feet of air containing 114 billion gallons of water.
The average Atmospheric Water Vapour Residence Time is around 8 days The median is 5 days and Death Valley’s topography is a valley which would trap more moisture, but we’ll use the average instead.
This represents a moisture turnover rate of about 625,000 Liters/second (or 1.45x10^10 gallons/day).
So, one of these devices would consume .000185% of the moisture that enters Death Valley every day.

Given enough people and time, we have a track record of messing stuff up.
ground water is a completely different beast. This device harvests moisture from the air.
You are assuming that there will only be one device used by a careful and considerate individual.
I can think of many companies that would 100000% set up a moisture farming complex if it was financially feasible. Who gives a fuck about the environment? It’s basically free water from nothing, right?
Nobody is deploying these at scale to harvest water to sell, it’s way too expensive. Probably even more so than desalination.
These kinds of devices would be useful in areas where they didn’t have access to preexisting infrastructure. There the comparison would be between operating one of these devices or air lifting water in by helicopter. The fact that it’s expensive isn’t as much a concern when the alternative is to pay for airlift delivery.
This could be interesting for a mars settlement.
One problem maybe kinda hypothetically down. Ten thousand more to go.

Bruh.
I was researching ai before llms for a gen ed class, this isn’t the sensationalized type of ai, ai in medicine and sht is pretty cool. Hospitality ai is getting too good too fast tho. Robot hotels and restaurants would not be suprising.

This is likely not the Generative AI, LLM-slop type of AI you’re thinking of.
I hate generative AI. But other forms of AI and machine learning have been used for much longer and haven’t facilitated the building of ecologically harmful datacenters.
For example, AlphaFold, which is an AI program that can predict how proteins fold and is an incredibly useful tool.
I expect that the use of AI here would be similar: something trained for a specific purpose, not just generic generative AI tech like ChatGPT
Reading that felt like my brain was trying to chew glue
