It looks like the paper is paywalled and not yet on scihub but i did find 38 pages of supplemental information with more details than the article.

Or maybe the product just isn’t for you, but for people who pay significantly more for, or possibly don’t have access to drinkable tap water at all.

It’s a solar distillation machine. The compact size is useful but there are dozens of ways to do this for almost free as long as you were within reach of an ocean. You can dig a hole in the sand put a piece of clear plastic over and a catch basin in the center and do the same thing. It’s interesting but not really earth-shattering.
You can’t “just do this” because you live by the ocean. You’re over simplifying it because you aren’t impressed.
For coastal people of impoverished or war-ridden locations with tainted or unavailable groundwater supplies, this is amazing if it becomes reality.
Your normal isn’t most people’s reality. Clean drinking water is not ubiquitous.
Are you telling me you can’t make a solar still out of a sheet of plastic a bowl and a hole in the sand at the beach? Because if you don’t think that works we have no further need to communicate.
Hope much drinkable water are you generating with your sand hole and plastic? This thing can allegedly generate liters per hour. Enough to sustain a decent sized group of people.
The numbers provided are qualified with “if they can scale it” up. So they don’t even actually know that they’ll get that rate.
Edit: MythBusters did it They pulled a about a half cup an hour out of a 6-ft wide hole. Best case if you are engineering this you could put a frenzel lens in front of a pan of salt water your energy conversion would be like 99%. For using sunpower, The amount of water you’re going to extract is directly related to how much energy you can collect.
I’ll believe their numbers when they actually bother to scale it.
The big one being “if it could be scaled up to a size of a suitcase”
That’s not very lofty, which makes me all the more skeptical.
“If” seems like a weird word to use for something the size of a suitcase.
Yeah, it doesn’t instill confidence. Like how small is their proof of concept, if they even have one? Assuming this isn’t all theoretical and nothing has been built.
I have family that can’t drink their tap water because it’s practically brackish (is was entirely brackish when someone pierced the aquifer boundary and created a hole that filled the underground reservoir with the nearby sea water, that lasted about 18 months, the entire community was on water that was being trucked in while a new well was discovered and drilled), their water is insanely subsidized, and still pretty expensive. The community is about 200 houses, each with access to Ocean/River inlet water, I don’t know a single one of them that wouldn’t go for this option. Their water is so heavily mineralized that filters lifetimes are hours to days. And then maybe they can allow the aquifers to refill, and maybe their houses wouldn’t be sinking as quickly…

Your tap water is expensive! Is that a typical rate? Its $551 for me for the 5l/hr for 5 years. $0.0075 per gallon. This is in UK. Its billed at £1.98/1000l.

5 gallons per.hour? The article says 4-6 litres - a little over a gallon.
