Here’s some of the discussion in the article:
Two-thirds of the world’s population is experiencing water shortages (1). The water in the form of vapor and droplets in the atmosphere, estimated to be about 13 thousand trillion liters (2), is a natural resource that could address the global water problem. Although there has been interest in dewing (3–6) from moist air and fog capture (7–9), these processes require either the frequent presence of 100% relative humidity (RH) or a large amount of energy and thus are not viable solutions for the capture of water from air. Ideally, a water-harvesting system should operate with a material that can take up and release water with minimum energy requirements and that is powered by low-grade energy sources, such as sunlight, in order to potentially allow its deployment in households, especially those located in sunny regions. Here, we demonstrate water harvesting by vapor adsorption using a porous metal-organic framework {microcrystalline powder form of MOF-801, [Zr6O4(OH)4(fumarate)6]} (10) in ambient air with low RH typical of the levels found in most dry regions of the world (down to a RH of 20%). We also report a device based on this MOF that can harvest and deliver water (2.8 liters of water per kilogram of MOF per day at 20% RH) under a nonconcentrated solar flux less than 1 sun (1 kW m–2), requiring no additional power input for producing water at ambient temperature outdoors. Porous materials, such as zeolites, silica gels, and MOFs, can harvest water from air by adsorption over a wide range of humidity values (11–13). However, conventional adsorbents (e.g., zeolites and silica gels) suffer from either low uptake of water or requiring high energy consumption to release water. Although MOFs have already been considered in numerous applications—including gas storage, separation, and catalysis (14–16); heat pumps (17, 18); and dehumidification (19)—the use of MOFs for water harvesting has only recently been proposed (10). The flexibility (20–22) with which MOFs can be made and modified at the molecular level, coupled with their ultrahigh porosity, makes them ideally suited for overcoming the challenges mentioned above.


This is a bit more serious than the old, frequently-debunked “dehumidifier in the desert” stuff, because it doesn’t depend on cooling the air to get the water out, but using a molecular sponge. If you pump enough air over that, you’ll eventually fill it up, and you can drive the water out by heating it up.
The guy behind this is a serious organic chemist, and his Nobel prize was actually for pioneering and developing these molecules, so it’s not a case of “Nobel prize winner does daft stuff about a subject he’s not an expert in”, either.
I’m still reserving judgement on whether this will be economically sensible, but I’m not dismissing it immediately, either.


This guy got his Nobel prize for molecular sponges that can bind and release water.


I’m currently an Ubuntu user, and the thought of using a GUI for package management is so foreign to me.


I’ve had a few issues along the years. Linux user since 1997

I didn’t know that was even legal.


The Belgarion novels by David Eddings. It would have done well as a trilogy, but the initial five-book series was OK as well. And then came The Malloreon, or The Quest for More Money. I finished it because I’ve got a bit of a completionist streak, but not because it was good.
And then I found out what kind of person Eddings was.


All tumours, no exception, contain dihydrogen monoxide.


The most common pushback on the car wash test: “Humans would fail this too.”
Fair point. We didn’t have data either way. So we partnered with Rapidata to find out. They ran the exact same question with the same forced choice between “drive” and “walk,” no additional context, past 10,000 real people through their human feedback platform.
71.5% said drive.
So people do better than most AI models. Yay. But seriously, almost 3 in 10 people get this wrong‽‽


Yeah, think about that while fingering A minor or picking a G-string.


I must have been living under a rock, because I didn’t even know that codeberg existed. I’ve just created an account there, added my ssh key, and successfully pushed a project there. Will be migrating as much as possible (focusing on code that might actually be interesting to others) over the weekend. Thanks!


It happened to me quite a few times before I realised what was going on. You click the time and then click “go”. It takes less than a second.


I’m about to replace a once year old phone because I can’t flash the ROM, and I hate Xiaomi’s native apps and don’t trust them anymore.


My previous phone was a Xiaomi on which I installed LineageOS. I was very happy with it, but my GF’s son had a very very old phone, so I changed it after only 3 years and replaced it with another Xiaomi. I’m deeply unhappy this time because they’ve made it practically impossible to unlock the bootloader without using dodgy unverified tools. It’s only a year old and now I’m replacing it with a second hand Pixel.
Before the first Xiaomi, I had a OnePlus that I kept for six years.


Ah, good old aposematism!


But you’re foolish to believe the Bin Laden raid into Pakistan was any less internationally criminal than the attack into Caracas.
There’s a big difference between kidnapping the president of a country and kidnapping somebody who is internationally wanted and who the country in question denies harbouring.
Sure, both are violations of international law, but one is easy more serious than the other.
