MIT engineers and collaborators developed a solar-powered device that avoids salt-clogging issues of other designs.

Desalination can be as easy as evaporation. But the volume over time is abysmal.
The faster you clean it the faster you build up the salt.
Like everything, problems appear at scale that aren’t even a concern at the individual level.
Big box with pipe pointing up in the middle that exits the box through the bottom to reach a collection tank
Fill with salt water without going past the pipe opening
Add transparent lid with a slope towards the middle so the water condenses and drops in the pipe
Go do whatever you want all day, you’ve got a passive drinking water creator and nothing to clog since solids just accumulate at the bottom and can be scooped out as needed.
Bet Nestle shuts this shit down somehow…
Edit: damn I can’t spell for shit
Cheaper than tap but at a 500% markup for CoNvEnIeNcE! You know that if it’s cheap, the large black scarf buckets (c*pitalists) will come in and force the prices to go up until nobody can afford it.

With my (admittedly limited) understanding of the topic, extracting the water from ocean water is a relatively simple process.
The problem is what do you do with the brine afterwards. The process featured in the article makes it harder for the brine to clog the system, which is admittedly an important step. But you can’t put the brine back into the ocean without risking killing local wildlife.
And I’m not under the impression that there are any practical uses for brine, at least not at that scale.
Something like this, I’d bet! https://www.youtube.com/watch?v=Ejvvou7d-kg
It is the same thing.
Yet somehow makes me less interested than the article.
It’s a solar still with running water. That’s it.
How tf did it take MIT engineers to figure that out?
It is explained in the link.
A hint, just after the title: “MIT engineers and collaborators developed a solar-powered device that avoids salt-clogging issues of other designs.”
Yeah, they developed a solar still with running water. That’s it. It’s a solar still that uses moving water to get rid of the salt.
