I appreciate this style of writing. Straight to the point. No 12 paragraphs about someone's grandmother falling in love in Italy with a plastic bag.

You're probably talking about cooking/recipe blogs? I need those 12 paragraphs and all the ads to get to the recipe. It's dopamine.

Nearly all passive water-from-air devices described in articles are based on false claims. Peltier-based, desiccant/absorption/adsorption based, etc. All end up not working, or not existing. This has been common for ~10 years.
Which category does this fall into?:
- Fraud
- Incompetence / misunderstanding that wasn't cleared up prior to publishing an article
- Neither; this works as expected

The design seems reasonable. It seems like a scaled down version of this MIT one that uses similar principles:
> Over this period, the device worked across a range of humidities, from 21 to 88 percent, and produced between 57 and 161.5 milliliters of drinking water per day. Even in the driest conditions, the device harvested more water than other passive and some actively powered designs.
so its making a shot of water ever couple days, provided its not too dry?
you need to scale way way up, not down

Many thanks for your link to the article, it was a very interesting read; fascinating to learn how glycerol interacts with lithium salts...
sciencejerk 16 minutes ago [-]
The team’s new design significantly limits salt leakage. Within the hydrogel itself, they included an extra ingredient: glycerol, a liquid compound that naturally stabilizes salt, keeping it within the gel rather than letting it crystallize and leak out with the water. The hydrogel itself has a microstructure that lacks nanoscale pores, which further prevents salt from escaping the material. The salt levels in the water they collected were below the standard threshold for safe drinking water, and significantly below the levels produced by many other hydrogel-based designs.
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

It is a dessicant dehumidifier, useless for the same reason as this MIT/Berkley thing from 9 years ago.
Collecting water with tarps is just strategic collection of condensation/dew. Clothing has the issue of often being warmer than ambient because people are warm blooded, so it's unlikely water would condense from the air(though it can condense on the inside from evaporated sweat).

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

MIT came up with a device that harvests water from air few years back. What happened to that project?

depending on actual conditions you are in, it could potentially double (or more) the time before you die of thirst if it was your only source of water.
brewdad 3 hours ago [-]
I do wonder about the tradeoff between excess perspiration due to wearing heavier materials versus the ability to collect water, especially on the days where replenishing fluids is most crucial.

from what I can tell, you dont have to wear it?

Assuming it's an "all-weather" jacket I think it would be cool for it to spout out umbrellas when it starts raining, batman style, to catch rain water as well and drop it into pouches. Mp3 player would be great as well.

My first thought was “yay a stillsuit” - but this grabs moisture from the air, not the wearer’s body. So no. No stillsuit yet.

Would you want it? I thought you were supposed to urinate and defecate in the suit so as to maximally retain moisture.

A big step towards a stillsuit anyways ;)

This sort of thing can't work as it would break basic laws of thermodynamics. Best case it's a dehumidifier with extra steps.
donkers 3 hours ago [-]
Why would it break the laws? Per the article it uses the heat from sunlight to do some of its work, it's not some kind of magic fabric.

So a dehumidifier with extra steps.
Supermancho 3 hours ago [-]
"extra steps" meaning wearable dehumidifier. Are there other wearable dehumidifiers to produce drinking water? I don't think so.
A reductive assessment (to a specific feature) of a novel idea, does not make it less interesting.
jojobas 2 hours ago [-]
You can wear silica gel since about 1918 - only needs some heat to get the water out and cold to condense it.
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.
Which category does this fall into?:
https://news.mit.edu/2025/window-sized-device-taps-air-safe-...
So my vote is for working as expected.
