Frank Herbert's Moisture Traps May Be a Reality
Omomyid writes "In the seminal science fiction book 'Dune,' Frank Herbert envisioned the Fremen collecting water from the air via moisture traps and dew collectors. Science Daily reprints a press release from the Fraunhofer Institute in Stuttgart, where scientists working with colleagues from Logos Innovationen have developed a closed-loop and self-sustaining method, no external power required, for teasing the humidity out of desert air and into potable water."
If you extract moisture from already very dry are do you not create a dead zone down wind?
There is life everywhere in the desert, most of which is tuned to live on very little water, but all of which need water from some source occasionally.
Pushing humans into these areas where the only source of water is minimally moist seems rather pointless and ill advised.
Would it work on mars?

Walk without rythm, fellow travelers.
What I really need is a droid that understands the binary language of moisture vaporators.
I'm glad that people are focusing on answers for people in underprivileged parts of the world, but it's not some sort of magical discovery.
You must have read the wrong article. They never claimed it was magic.
P.S. Claiming you haven't read the article doesn't absolve you if you make a mistake.

Clearly, this is on a larger scale and far more impressive than what you did when you were 12.
Seriously, just because you did something which is conceptually similar, doesn't mean that this isn't an advance. Conceptually, flight hasn't changed since the Wright Brothers. Practically, it obviously has.

Thanks for clearing that up. I thought you meant he would suddenly notice Solid Snake sneaking around his desalinization plant.
Given the state of scientific knowledge in 1965 (when dune was published) it's a lot harder SF than some people seem to realise.
Herbert did some serious background research for Dune IMO.
Sure bits of it seem *now* to us as absurd as Doc Smith's diesel-engined spacecraft, but in 1965, 12 years after the discover of DNA, 17 years after the initial formalisation of classical information theory, when computers were still mostly small-room-sized, the idea the genetic code could pass down memories wasn't all that outlandish a hypothesis - in fact it seemed pretty reasonable. If you were writing now you'd probably come up with people being genetically engineered to add informational appendicies to germ line DNA rather than the ability being built-in by evolution, but there's nothing impossible about it. And if you pay attention to the books, you'll note that being able to "see the future" doesn't work in a naive way either, it's clearly been modelled on "quantum collapse" and "many fingered time" that any passing 1960s physicists would have talked the ear off Herbert about.
And with very powerful figures *right now* calling for the Death of the Internet, is a ban on computing devices really that outlandish? Sure, the chances of them winning are slim in practice, but still.
Do you know why it's illegal to collect rainwater in a barrel in Utah and Colorado? If there is only a gallon of water in the air over an acre of land, removing a quart does in fact change the balance of things.
That's a load of pseudoscience, backing up a law that exists only for revenue, cronyism, and political control. If you store water off your roof or that falls from the sky, and then use it in your home or for irrigation, you're returning that water right back into the water table...in fact, use in the home returns it more effectively, because it is reintroduced a few feet under the soil by your septic system. You're not 'stealing' water- it doesn't go anywhere.
If you want to know the real reason laws like that exist, read The Milagro Beanfield War (annoyingly, that link is about the movie, not the book.) I read it in middle school, and it gave me great insight into how big business pushes citizens around.
Also, you can take a look at what the Israelis are doing to all of the rivers that feed into or border Palestine for a great example of how water is controlled for racial oppression and political power.
Please help metamoderate.
A large pile of rocks will do the same thing, pretty much.

Same end effect, with no tech. Much cheaper, I'd bet. :)
