That’s the best thing I’ve read this year.
in the future they will use the oceans and transform it to clean drinking water cheaply i think this is a step in that direction
Sounds nice. Will be interesting to see how long the finely engineered surface lasts and any toxicity resulting from it wearing down.
Given the research paper, the only next *best* thing these people can do is open-source their entire method.
Don’t be greedy. The money will come. Open-source the method, and help save the world.
Phew! Data Centers everywhere won’t go thirsty.
Praise it!

Can anyone say how much energy it uses compared to the current state of the art (desalination plants I’m guessing?). They claim it’s more energy efficient but don’t give any numbers in the press release or from a quick skim of the paper.
Or is it less wasteful in generating salt? It sounds like it produces solid salts which need further processing.
I’m struggling to see how this is better than previous techniques.
Yes, but it makes pinking water, greening water, and bluing water as a side effect
It’s funny how every week we come up with a new solution to desalinization but yet the problem still exists…

>Our ABF-STIC is used to purify actual ocean water from Pacific, Atlantic, and Indian oceans and operates continuously over weeks without maintenance, achieving an average evaporation rate of 1.76 ± 0.04 kg m−2 h−1and salt harvesting rate of 61.74 ± 2.46 g m−2 h−1 under one sun, corresponding to ~74% evaporation efficiency based on the bulk water vaporization enthalpy and nearly 100% salt extraction
That’s pretty good. For reference, current desal plants usually hit 10+ kgm2h. Scaling this could be hard given the nano-precise construction but at least the materials are cheap
So how much fresh water can one of these panels produce per day?
This could be huge if it scales, seems like the etched wicking metal wouldn’t have to be constantly replaced like desalinization filters do. This technology might make a lot more areas habitable.
This is great. I don’t expect the AI war to end super soon, so we really need this.
Question to the actual scientists here: will something like this be able to offset the adverse effects of Thwaites‘ Glacier as it melts? From what I know, the glacier can make sea levels rise up to two feet. If something like this were to be put on a larger scale, would we be able to use enough sea water to reduce the sea level rise caused by the glacier?
Without waste? If they are not taking anything out, they are not making it drinking water.
is this how we beat ocean risings?

Fig 6 includes a prototype condenser that recovers fresh water. The salt cake is a by product that has to go somewhere.
Very nice! A lot of People see desalination powered by Solar energy as a handy solution but you have a problem with all the brine.
You get fresh water from the seawater and also some very strong brine which you shouldn’t just dump into the sea because everything around your outlet pipe will die due to the salt content in the water going from normal ocean to dead sea.
I made fresh water from salt water every day when I lived on my sail boat. We used a reverse osmosis watermaker system. Most live aboard sailors have them. They don’t use too much power (depends on the size of your system) and the byproduct is really salty water.
