A jacket that harvests drinking water from the air

erelong•18 minutes ago

I've heard of collecting water with tarps and assume this is like a vest form of that:

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.

This reminds me of Dune. Does this really work tho?

Incredible innovation.

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

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:

So my vote is for working as expected.

Many thanks for your link to the article, it was a very interesting read; fascinating to learn how glycerol interacts with lithium salts...

Makes sense since we're speedrunning the other parts of the Butlerian jihad

I don't know about the rest of you, but if somebody spots Shai-hulud out in the Sahara I'm outta here.

At the end of Dune.... Chani is heartbroken... Needing to get away...

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

Out of here to where?

Outside of the environment?

Honestly, bring on Leto II. Fuck it.

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•about 2 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.

keithnz•about 1 hour ago

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

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

Seconded. I wonder which would taste better though.

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

g-b-r•about 3 hours ago

Just wear it in reverse ;)

A big step towards a stillsuit anyways ;)

I wonder if it has microplastics, but probably depends what kind of fabric was used

Vaporware has never tasted so good or been so refreshing.

Vaporwear*

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•about 2 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.

jojobas•about 2 hours ago

So a dehumidifier with extra steps.

Supermancho•about 2 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.
