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.

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.

That water was in its way to somewhere, though. What is that other area gonna look like now that this device intercepts the water?

[–] SweatyFireBalls@lemmy.world 55 points 1 month ago (1 children)

Sounds like that other area needs to pull up on those bootstraps and make a water machine for its needs then.

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.

[–] Steve@startrek.website 10 points 1 month ago (2 children)

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.

Atoco harnesses the power of AI to bridge the gap between scientific discovery and real-world implementation, transforming innovative research into scalable solutions. By integrating machine learning and AI with reticular chemistry, we dramatically reduce the time needed to develop, optimize and scale our novel nano-engineered reticular materials for carbon capture and atmospheric water harvesting.

Bruh.

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

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 has been debunked before. To get 1000liter of water out of the air, the air needs to hold that much water.

[–] Slashme@lemmy.world 35 points 1 month ago (2 children)

This is a bit more serious than the old, frequently-debunked "dehumidifier in the desert" stuff, because it doesn't depend on cooling the air to get the water out, but using a molecular sponge. If you pump enough air over that, you'll eventually fill it up, and you can drive the water out by heating it up.

The guy behind this is a serious organic chemist, and his Nobel prize was actually for pioneering and developing these molecules, so it's not a case of "Nobel prize winner does daft stuff about a subject he's not an expert in", either.

I'm still reserving judgement on whether this will be economically sensible, but I'm not dismissing it immediately, either.

I used to work for a company making a similar device, the chemistry behind the technology is actually a well researched topic, and there are many kinds of various chemistries that can achieve a similar effect. Silica gel packets are the most common, a cheap solution that extracts moisture from the air, but is non-reusable.

These MOF compounds are useful because they have a fundamentally different method of collecting the water molecules. The framework traps the molecules inside, which can be later released with heat. Thermal solar power is free, but does require careful management of the rest of the device such that the material can get hot enough (usually around 100c), which also providing another surface to condense the vapour. I spent alot of time designing and testing such panels. They do work! I can post pictures of fishtanks of water later.

There truly couldn't be much of a downside to these technologies. The real alternative is desalination, which produces hyper concentrated salt pools, or well water extraction, which is also bad...

The reason these technologies is usually due to the cost effectiveness to produce the material, and to build the enclosure around the material. The panels have to scale very large to get any reasonable about of solar power, plus the condensing and collecting mechanisms also add weight and cost. Water is not an expensive product, so at the end of the day, the economics don't always work out favourably.

Happy to answer any questions about the technology.

[–] Hi_ImSomeone@lemmy.world 12 points 1 month ago* (last edited 1 week ago)

Here's a picture of one of our tests generating water from air! We got 21kg from a large-ish panel.

I can't show much else but I can guarantee we did harvest the water from the air.

[–] PapaStevesy@lemmy.world 6 points 1 month ago (1 children)

There truly couldn’t be much of a downside to these technologies.

What you mean to say is "We don't know what the downside will be untill these technologies are implemented and used for a long time and then studied." Otherwise you sound like the well-intentioned-but-unhinged chemist that accidentally starts the zombie apocalypse at the beginning of the movie.

Well... There would also have to be water to actually collect from the air. Thunderfoot made a really good video about these dehumidifiers when yet another one popped up on Kickstarter claiming to end water shortages.

Oh no, the same scam again, when will people realize that putting dehumidifiers in the desert, where there is little to none humidity in the air does not produce significant quantities of water.

You can claim that your solution produces thousands of liters of water, but in practice its obvious that you cannot extract more water than what's already im the air, once you extract it, there is nothing left, it may work at first, but is not going to work continuously forever.

This is another example of a promised technology scam, pay me for the development and once it doesn't work, disappear with the money. People keep falling for it for some reason.

Well, unless he sells the patent to Nestle, it's COMMUNISM. Water is private property. /s

[–] Tattorack@lemmy.world 12 points 1 month ago

It's a dehumidifier. There's nothing to patent that hasn't already been patented.

[–] TigerAce@lemmy.dbzer0.com 19 points 1 month ago (2 children)

There have been so many of these devices promoted in Kickstarter, dragons den, etc.

I'm highly sceptical, as so far scientists have told me there simply isn't that much moist in the desert air to get even one liter of clean water per day. You simply cannot create water out of nothing.

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.

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.

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.

https://www.nature.com/articles/s41598-020-58405-9

"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.... "

If people keep reinventing the fucking dehumidifier I'm going to start beating these dipshits bloody. Or maybe I should just collect the old beater ones I see at estate and yard sales to make YouTube videos making fun of them. Regardless this is barely worth praise for an amateur engineering project let alone a nobel prize.

[–] pineapplelover@lemmy.dbzer0.com 6 points 1 month ago (1 children)

I wonder if these guys realize that if you suck up all moisture from the air, it will be pretty dry and you will need the same amount of water to replace the water you displaced

[–] Corkyskog@sh.itjust.works 12 points 1 month ago (1 children)

I am guessing they are aware how their machine works. Air isn't usually stagnant, if you have moving air that means moisture is replacing it.
