Which category does this fall into?:

  - Fraud
  - Incompetence / misunderstanding that wasn't cleared up prior to publishing an article
  - Neither; this works as expected

So my vote is for working as expected.

so its making a shot of water ever couple days, provided its not too dry?

you need to scale way way up, not down

So uh, how do they get the salt out of the nanostructure? This design seems amazing but it seems like many of these designs have issues with salts accumulating and clogging up parts thereby requiring some manual maintenance or replacement parts

    How do I protect my recipe?
    A mere listing of ingredients is not protected under copyright law. However, where a recipe or formula is accompanied by substantial literary expression in the form of an explanation or directions, or when there is a collection of recipes as in a cookbook, there may be a basis for copyright protection. Note that if you have secret ingredients to a recipe that you do not wish to be revealed, you should not submit your recipe for registration, because applications and deposit copies are public records. See Works Not Protected by Copyright (Circular 33) (PDF, 113 KB), section "Names, Titles, Short Phrases."

Typo, “interesting”; “interneting” also works.

> write the first 6 paragraphs of an imaginary news article that starts with a one paragraph hook and then has 4 paragraphs of a preamble story that has nothing to do with the premise. The last paragraph should somehow bring it back tangentially to the original point

and this is what it came back with. This is what reading a lot of articles feels like: padding word count with "flavor":

> TOKYO — A catastrophic logic failure in the global banking network has permanently erased all digital financial debts worldwide, throwing international markets into immediate, unprecedented chaos.

> Deep within the tranquil countryside of Wiltshire, Arthur Pendelton adjusted his favorite tweed cap against a surprisingly brisk autumn breeze. The 72-year-old retired carpenter had spent the better part of his morning inspecting a stubborn patch of moss creeping across his garden wall. For Arthur, the slow, predictable rhythm of rural life provided a comforting contrast to the frantic pace of the modern world he happily left behind. He noted with mild satisfaction that his prize-winning marigolds were finally showing signs of recovery after an unusually dry summer.

> Across the English Channel, Marie Dubois hurried through the cobblestone streets of Lyon, her mind entirely occupied by a sudden shortage of Madagascar vanilla. As the head pastry chef at a bustling neighborhood bakery, Marie knew that a Saturday crowd would tolerate many things, but a subpar crème brûlée was absolutely not one of them. She waved a brief, distracted greeting to the local florist who was busy setting out fresh buckets of lavender. A stray tabby cat darted out from beneath a café awning, briefly disrupting her frantic mental calculations regarding flour ratios.

> Meanwhile, on a remote research vessel drifting through the choppy waters of the South Pacific, Dr. Aris Thorne stared intently at a series of sonar readings. His team had been tracking the migration patterns of a specific pod of humpback whales for nearly six weeks with very little success. The ocean was uncharacteristically quiet that morning, save for the rhythmic thrum of the ship’s diesel engine and the occasional cry of a wandering albatross. Aris sighed, rubbing his tired eyes, and reached for a lukewarm mug of black coffee that had long since lost its appeal.

> High above them all, in a climate-controlled laboratory in Tokyo, a prototype cleaning robot named Sparky spun in a slow, confused circle. A minor programming glitch had caused the machine to perceive a perfectly clean linoleum floor as a vast field of hazardous debris. Its small rubber wheels squeaked rhythmically against the polished surface as it repeatedly attempted to sweep an invisible pile of dust into its containment bin. Two interns sat nearby on a break bench, completely ignoring the robot while they debated the merits of various local ramen shops.

> It was this exact, minor programming glitch in Tokyo that a central bank AI subroutine mistakenly flagged as a critical system override code. Within seconds, the error spiraled out of the lab, flooded the global financial mainframe, and executed the irreversible command that wiped clean the world's ledger books.

It sounds easy, but eventually you can heat up whatever you use as heat sink and then you have to wait for that to cool.

Plus, you know, completely ruining thermoregulation by preventing heat loss through evaporation.

   Oh I'm a leavin' on a Shai-hulud
   Don't know when I'll be back again..

Maybe not for 3500 years, but look what world WWII brought after it ended. We need that millennia-spanning perspective.

Interviewer: But it must be somewhere… Well what’s out there?

Senator Collins: Nothing’s out there!

Interviewer: Well there must be something out there.

Senator Collins: There is nothing out there - all there is is sea, and birds, and fish.

Interviewer: And?

Senator Collins: And 20,000 tons of crude oil.

Interviewer: And what else?

Senator Collins: And fire

Wouldn't want to be drinking whatever this produces in the GTA though lol

If they were externally powered you might get the numbers to balance, but they are explicitly presented in the book as powered by the human inside, which subtracts even more time from how long you're going to last in the desert before you die.

You can build a larger thing that recovers your water and cools you via some other method that uses external power, but I think you'd be hard pressed to ever beat just bringing more water with you. It won't be long before you're spec'ing a vehicle and not a suit... and then that vehicle should probably just bring more water, too.

On the more positive front, there is an interesting technology for potentially cooling the Fremen in the middle of the desert that could be based on something real: Paint that cools you by dumping your heat directly into space. Here's a video of it in action and what you might call a prototype of a "suit" that works like this: https://www.youtube.com/watch?v=FnKNOPlR2Yo While that YouTube video shows off someone using that paint on clothes, it seems pretty likely that that would not last very long. Paint on clothes is exactly as silly as it sounds for a long-term approach. But hypothesizing that someone could make clothing or suits based on this approach has the advantage of not being thermodynamically impossible, as evidenced by the fact that at least one substance with these properties actually exists. On Earth, that suit won't work in cloudy weather, but on Arrakis that's not a problem. Tapping the local human power to drive some circulation of either air or a bit of liquid cooling attached to some lightweight fins or some other sort of surface area on your back or something and you might just get a suit that could hugely extend your ability to loiter in a hot desert environment. You'd still need water, but much much less, or, the same amount could take you much farther.

A big step towards a stillsuit anyways ;)

A reductive assessment (to a specific feature) of a novel idea, does not make it less interesting.

Then again, why would you want to wear your dehumidifier (ok ok water harvester)? Is it for excursions into damp areas, so that you can then return to your dry home to extract water?

Then, I believe everything in this video still applies.
