So, the bottle thing is based on a construct with a limited power supply available, and promises made of performance.

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.

I saw this topic and brought it to Phil's attention. He tweeted he will be debunking this as well. It does claim to be different from a Pelletier collector, but is still violates thermodynamics to work as they claim.

Not surprised but still a really cool concept. Maybe the technology from these MOF's could be used to actually create one.

Awesome, now someone needs to invent the droids for real...Starwars actually does reflect future technology just as Star Trek did....

Love Metropolis...although the coupling with Hel may be problematic, as it is rumored that CP3O may be gay.

Not that there is anything wrong with that.

George Lucas was very careful to identify Metropolis as a source for some of his droid designs:

I already assumed 100% efficiency in my estimations. It doesn't change the amount of air the device would have to deal with.

It's right out of Atlas Shrugged!

"Not likely" Please explain your reasoning.
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.

Yes, as it is currently configured, but SoKal does have most of that. Tweaked and refined, they might provide independent sources in 10-20 years.

Hi Nickursis,
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.

Kalifornnia alone will be able to great amounts from it as their coastal humidity is twice what they tested for.
