The system can function in air with 20% humidity or less. But these 1,000 liter a day machines are not small, at around shipping container size.
It’s a Fremen wind trap.

I wonder, if that was done, how much energy would be transferred from the atmosphere (condensing water vapor transfers a huge amount of energy as heat), and what impact that might have on climate instability. I also wonder if there’s a way to transfer the heat energy to somewhere “safer”, like underground.
And if these could be used in places that aren’t as bone dry, even better. I mean all the big powerful storms have been bigger and more powerful because of all the extra moisture in the air.. if we could throw these everywhere, pull some of that moisture out, and use it to supply portable water instead of drawing from reservoirs, that seems like it might be a many-win option.

I would guess there would be no heat impact on the climate. The same heat was already in the climate, it’ll be expelled in a similar way.
Fossils fuels extract stored energy and burn it, but it’s not the heat they create that warms the climate. It’s the CO2 they release that reduces the rate at which heat is expelled from the planet causing additional energy to be retained.
This type of technology may reduce climate change if it’s used instead of desalination powered by fossils fuels. Or if the heat that was generated was captured and used for heating homes instead of fossils.
The amount of energy we get from the sun far exceeds how much energy we can produce. We can’t really impact the climate by cooling and warming the planet directly. It’s leveraging effect of greenhouse gasses insulating the planet which causes climate change.

In other words, a dehumidifier.
There’s no such thing as a free lunch. To condense water fro air, you need a lot of energy, considering how little humidity there is in a desert, it would be better to just use that energy to bring the watter from somewhere else rather than running the dehumidifier.
What pisses me off, is that we’re willing to build thousands of kilometres of pipe to transport dinossaur juice but not watter.
Fuck this capitalist system.

A passive water harvester based on MOF-303 has been designed and configured to achieve the highest efficiency among passive designs. A water harvesting capacity of 285 g H~2~O per kilogram of MOF-303 per day with only ambient sunlight and no power or other energy input was achieved. The MOF cartridge design and the condenser surface treatments were key features in achieving high water harvesting efficiency especially when tested in the field (Death Valley National Park).
It’d be really nice if people actually read the article instead of just assuming they already know everything.

This system does not require a power source.

Water has only one T. One of the many things wrong with your argument. Read the article.

This is only the umpteenth such device this past decade. I’ll believe it when I see it deployed and used in real life scenarios.

Giant heat pump?
You can’t fool the laws of thermodynamics.

No need to fool the laws of thermodynamics, it’s enough to fool investors

The article explains that the system doesn’t use power or any type of refrigerant, instead it uses a new type of material with large surface areas in a small package to capture/condense the water out of the air while utlizing wind and the sun to help accomplish its goal.
I would agree that up until now the only viable technology was a dehumidifier which takes great amounts of fossil fuel energy, but this isn’t the case here.
