Open sourcing a dehumidier isn't very exciting, mind you
I think it's very exciting. I'd love to have everything in/around my house open source.

People need DCs too, not just corporations.
Wait, what? What exactly is a data center by your definition? What individuals (that are entirely disconnected from corporations) need them? How many individuals have personal data centers of such a scale that they would need to produce liquid water on-site for their computing needs? I genuinely believe you’ve described an entirely theoretical person that doesn’t reside in this universe.
I need one to host successful blogs and my data hoarding.

#103It turns out they are very similar to binary loadlifters in most respects.
You're thinking of vaporators. Binary loadlifters are heavy-lifting droids, though the binary programming language of those droids was quite similar to that of moisture vaporators. Maybe that's what you meant.

#104If they’re giving it away for free, that must mean there is a fatal flaw they could never design around and are confident nobody else will either. What’s the point then? At least tell us why it’s a dead end.
Here's their summary blog post: https://x.company/blog/posts/sharing-project-h2e-with-the-wo... Allow me to snip a few quotes: "After three years of work, the team felt confident they could build a device that would produce water for $.10 per liter; however, it would have taken significant development work and iteration to prove feasibility at $.01 per liter. Additionally, the next phase of work for the project looke…
this is just standard boilerplate at X which really means "the team and/or the executive sponsoring the project got bored and/or realized things required more professional work, and/or the idea wasn't really that great in the first place and the exterior world realized that"

#105An open source dehumidifier ? Haven’t there been umpteen attempts at this? I thought there’s not that much water in the air. The volume of air to move must be crazy. Maybe I should read TFA
As far as I know every "water from air" is literally a dehumidifier and is going to produce dirty water at 1000x the cost of just driving water anywhere on earth.
This guy has done several busting videos on similar devices

#106Is it me or does this project have Dune vibes? Pity that it couldn't move forward.
That's because it's a fundamentally dumb idea and the promises made by proponents violate the laws of thermodynamics.

#107Check out Thunderf00t's videos cricising solar water collectors, e.g.:
- https://www.youtube.com/watch?v=vc7WqVMCABg - Zero Mass Water: BUSTED! "Honestly, it drives me crazy how many people have reinvented the dehumidifier, put a solar panel on it, and the media has danced around like theyve just saved the world!"
- https://www.youtube.com/watch?v=aPvXnmBIO7o - Self-filling water bottle: BUSTED! "The fact that its thermodynamically impossible seem to stop 'science communicators' from promoting this. The fact that its a really dumb, and not particularly inventive idea didnt stop the 'science communicators' from promoting this. Kinda depressing really."
Problems include:
- it's much cheaper to bring in a tanker of water from somewhere else, than for the electricity to do this.
- It's a dehumidifier; in places where the air is wet, it rains, and you don't need it. In places where you need it, you need it because there's not much water, so it doesn't work well.
- It's going to be prone to growing bacteria; warm and moist.
- It needs a vast volume of air; when water becomes steam it expands 1000x. Which means to go the other way you need at least 1000 litres of steam dragged through for a litre of water. Air can be around 4% water says Britannica.com, so 20,000 litres of humid air for a litre of water if it's perfectly efficient. Thunderf00t's estimate is 50,000 litres of air for 1 litre of water; And the air needs to be cooled. That needs big fans and lots of power (air is heavy to move).

#108The concept has been debunked over and over, e.g. by Thunderf00t. https://www.youtube.com/watch?v=LVsqIjAeeXw
Isn't the video you linked to a completely different concept? How does the debunking in that one apply to this one?
It is a very different concept, yes.
Considerations of efficiency and power consumption are relevant... but not much else. Generally such devices are either too expensive, too maintenance heavy, or utterly inefficient.
I'm not qualified to comment on, but I have found it interesting that it heats up the air (hotter air = can hold more moisture), passes the air through some material that's supposed to retain moisture, then cools it down with radiators. It seems that it would be more efficient in cold weather but would not perform nearly as well in a desert (where you need it to perform well as the moisture content is low during the day).
So maybe Mr. Thunderfoot will be able to debunk this too. If he can refrain from reusing Theranos and Boring Co footage.

I think you need more than just a YouTube video to "debunk" the nature paper that they have published and that is linked in their github. They seem to acknowledge that while there are some limitations it still is a viable source of water for a lot of regions. What is surprising is that thunderfoot didn't lose his habit of repeating himself over and over again. I'm counting 10 videos "debunking" the same idea of a bot…
> What is surprising is that thunderfoot didn't lose his habit of repeating himself over and over again
Yeap.
> Though to be fair, he's now more into into making misleading videos about SpaceX and obsessing over Elon Musk.
His videos are recursive.
You see, even videos having nothing to do with the subject at all, he will still find a way to include Hyperloop, Theranos and Boring Co. footage. Plus older videos. Like a house of mirrors.

Where do you put the left over salt? At those levels it’s both toxic for animals and toxic for plants. Even putting it back into the ocean isn’t simple. If you do it in one big batch, you would kill everything in that location for a while. If you do it slowly, that isn’t simple.
Sell it? Sea salt is an in demand product
There will be impurities, it won't be just NaCL.
