Now this is very interesting and Gault like. About time genius appears...

These guys are making a claim of a physical performance of a specific material, adn said they had confirmed the performance in testing, they also say:
This proof of concept harvester leaves much room for improvement, Yaghi said. The current MOF can absorb only 20 percent of its weight in water, but other MOF materials could possibly absorb 40 percent or more. The material can also be tweaked to be more effective at higher or lower humidity levels."
The water is being released by the materiel, then condensed, the condensation being done at ambient, which would certainly limit performance.
Just remember, in the 20 years before the Wright Brothers, numerous "scientists" and "experts" debunked and pilloried the idea of flight. It took a fundamental breakthrough in the application of power to weight (their little engine) plus an efficient wing design, to get the Wright Flyer off the ground.
The fundamental science is the hard part, the rest is just engineering.

Well done, blarman!
Not that there is anything wrong with that.

So the device will not work on dry air as the title state, their example is from 20-30% air humidity. They claim 2.8l in 12 hrs, assuming 30% humidity and I will assume 30°C since nothing else is stated and lower is worse. They would need to extract 100% of the water from 311 cubic meters of air assuming 100% efficiency, and this in 12 hrs. I know for a fact this is not possible by the device in the picture, and they do not say how much energy it used doing this. If we had just too much energy we could simply convert salt water to fresh water way more efficiently then this device would be able to extract fresh water from air, we don't do that today because it's inefficient.

For example, you could put something like this in the desert where there is little water. There is so little humidity, that you'd better spend the energy created bringing in water from somewhere else. Or, like Sam Kinison said: https://www.youtube.com/watch?v=P0q4o... .
A water harvester that uses only ambient sunlight to pull liters of water out of the air each day in conditions as low as 20 percent humidity, a level common in arid areas.
The prototype, under conditions of 20-30 percent humidity, was able to pull 2.8 liters (3 quarts) of water from the air over a 12-hour period, using one kilogram (2.2 pounds) of MOF.
Total amount of water in the air is based on Temperature. 20% relative humidity at freezing temperatures contains 1/8th the amount of water 20% relative humidity does at 100 degrees (F). For 2.8 liters of water at room temperature, the system would need to filter 50X shipping containers of air at normal efficiencies to achieve this. And to power this in the time claimed, you'd basically need 15 square meters of solar panels to do it. And that's assuming everything is perfect (perfect sunlight, perfect weather...).
There's no such thing as a free lunch...
Successful testing.
Thanks for the post. With regard to the table of cash, One can only imagine how the heads are spinning trying to figure an effective tax and the global warming effect we will be causing by lowering the humidity . Sarcastically , with out humor but as a prophesy. Alas the last thing the environazi's want is for a lot of people to have fresh water.
