The configuration of the device allows water to circulate in swirling eddies, in a manner similar to the much larger “thermohaline” circulation of the ocean. This circulation, combined with the sun’s heat, drives water to evaporate, leaving salt behind. The resulting water vapor can then be condensed and collected as pure, drinkable water. In the meantime, the leftover salt continues to circulate through and out of the device, rather than accumulating and clogging the system.
The new system has a higher water-production rate and a higher salt-rejection rate than all other passive solar desalination concepts currently being tested.
The researchers estimate that if the system is scaled up to the size of a small suitcase, it could produce about 4 to 6 liters of drinking water per hour and last several years before requiring replacement parts. At this scale and performance, the system could produce drinking water at a rate and price that is cheaper than tap water.
I think the main keyword here is could, unfortunately. I live in a first world country and could benefit from it, which means there’s very little chance nobody will snatch it up and abuse it.
Came here to say this, but i see you have it covered. I get sooooo tired of the “coulds” ,“woulds” and “shoulds” we see in article titles like this. What is more likely to happen… a promising new technology that’s cheap to produce, maintain, and reduces prices for the delivery of the worlds most needed resource is universally embraced by ALL…or Companies like Nestle, who’s massive water profiteering is threatened by this innovation, either buys out all the patents and sweeps it under the rug , and/or launches a campaign of legal litigation against it’s developers so that it never gets funded nor ever gets to the practical production stage.
I know what kind of world we’re living in… and it’s not one that favors the hope and needs of the many over the greed of the few.
It’s really awkward to see multiple reactions critical of the article, yet zero downvotes (well only mind now). Why?
Because this instance doesn’t use downvotes. The default interface doesn’t show downvoting, and attempts to downvote through another interface are literally discarded by the server.

You’re living in a world where some very rich countries such as Saudi Arabia are absolutely desperate for desalination capacity.
Of course, and That’s fine so long as it benefits everyone there equally. But Would you wager me the Saudi Government (or any goverment) is going to be that fair about it ?
Either way we have to wait and see where the Chinese developers take this to next.
we removed responsibility from groups of humans and called it incorporation. then we distilled pure human greed into what is now called the stock market, built on a lack of responsibility.
it is so gross… the rich are addicted to profit, the poor cannot see past their next paycheck.
we are all fucked
Jeeze you guys are so cynical 😂It’s true that many innovations from academic research fail to be commercialized or scaled. But it’s also true that many many successful technological innovations come out of academic research and impact the lives of millions.
The biggest barrier here will most likely be whether it can scale, not patent litigation.
You underestimate the greed of the .01 % …my cynicism comes from seeing them getting their way the great majority of the time because money.
