Edit: loads of gullible people here wanting to buy a bridge! Please invest your money and I'll wait for the inevitable "how could we have known this was a scam, nobody told us!!"
Yeah I'm sorry but I'm right out of the gate calling this a scam.
I'm not saying it is a scam but I've seen so SO many "free drinkable water!!" scams built by scamming absolutele idiots, that I'm first assuming this is bullshit until I've seen the actual designs and products for real
Again, not having read the article: if this is something with "please fund us, we will make it awesome" then you better close that wallet fast as you're about to be scammed.
It doesn't matter if it's university backed or not, even Stanford and MIT backed scam projects that first graders could have identified as a scam and turned up nothing
Unless they have a fully functioning system that produces at least 5000 liters of drinkable water per day, every day, this is a scam. I'll read the article after and update.
Having said all that, depending on where you are that can support a village or a single village idiot.
Edit: having read the article, I'm still staying on the "scam" part. For one: "In addition, unlike other systems, this one does not require batteries to store energy nor does it depend on an external electrical grid." is bullshit. If you want it to run at night you either need batteries, the power grid or a little garden gnome furiously cycling to power a generator. As said before: that it's backed by MIT says little to nothing
Your calling it a scam right out the gate. But you're not saying it's a scam. And you're not reading the article.
10/10
And you didn't read what I wrote.
I said most of these revolutionary techs are scam, because I quite literally see new scams like this on a near weekly basis. I've literally seen dozens of these revolutionary drinkable water miracle machines over the past decade and so far 100% of it was a scam so pardon me for being at least skeptical.
Arguments like "but MIT is involved, MIT!!" hold no water either because MIT and Standford have been involved in similar scams before, lending their name and credence to it.
Also, again, you didn't read what I wrote. I did read the article and sorry, it's not convincing.
Maybe YOU didn't read what you wrote.
Before waxing philosophical you should learn effective communication skills. And I'm not the only one who thought your opening lines were nonsensical.
Tell that to the Nature journal and the thousands of scientists who've read a paper on this specific system design since its submission and then its publishing in October 2024.
Simple: It doesn't run at night, as mentioned in the article. Also mentioned is this is actually more efficient than having a battery to also run at night.
It looks like it's just a test/demo of plumbing reverse osmosis desalination directly into solar power. I'm guessing there is mechanical energy buffering in the system, meaning that batteries aren't required to smooth power flow out.
For me, the question of how innovative it is comes down to kW input per gallon output. Doesn't matter to me if the power in is coming from solar, coal, nuclear, or hamsters in generator wheels, the efficiency of the system still comes down to power input and space required.
