Wind Turbine Extracts Water From Air
An anonymous reader writes "Getting access to enough water to drink in a desert environment is a pretty tough proposition, but Eole Water may have solved the problem. It has created a wind turbine that can extract up to 1,000 liters of water per day from the air. All it requires is a 15mph wind to generate the 30kW's of power required for the process to happen. The end result is a tank full of purified water ready to drink at the base of each turbine."
Finally, we've developed the technology to colonize Arrakis!
There's no -1 for "I don't get it."
A Slashdot story from 2009 on the same idea. That one wasn't operational at the time, though (except as a research prototype), and this seems to be from a different group.
10 PRINT CHR$(205.5+RND(1)); : GOTO 10
Now the birds will get dry eyes.
Will you need a droid that understands the binary language of moisture vaporators?
But I was going down to the Toshi stations to pick up some power converters!!!
If you read the article you will see that an operational unit is already producing 800 liters a day consistently. I love this stuff, the energy and raw materials to sustain the human race are all around us, just waiting for the right technique to take advantage of them.
Soooo, that's arid area and probably fresh water shortages licked, what's up next.
Smaller tropical islands are very humid but often don't have enough rainfall to keep an adequate freshwater supply, and as a result use desalination plants.
A turbine like this would work quite well in such an environment.
retrorocket.o not found, launch anyway?
...Then the people consuming the electricity can chose to use it to run moisture water condensers, or make electricity for things like running air conditioning?
Or, win/win: Put up wind farms that generate electricity.
Run electricity to dwellings. Have the dwellings run air conditioning systems that also collect condensed water.
Uh, Linux geek since 1999.
I'd say it has about as much effect as wind turbines do on the wind, ie not much. Its only sucking moisture out of a very, very tiny level of the atmosphere, and only a very tiny cross-section of that. They just won't have any appreciable effect, no matter how many of them you install.
Many deserts are also relatively humid.
Remember that deserts are defined by precipitation, not humidity. Deserts next to coastal areas lacking sufficient mountains to extract the humidity (such as Abu Dabi, referenced in TFA) are prime candidates.
This wouldn't work nearly as well in, say, Phoenix Arizona which is not only a desert, but is also arid and dry in every sense of the word.
I have no problem with your religion until you decide it's reason to deprive others of the truth.
Whew quick update - a tenth of a cent per liter would be the target

so it would have to be running ~150 years to equal that kind of throughput. With that said there are plenty of places it would be useful which are not accessable to desal tech without major infrastructure investment, so I can see value, while it's not the answer to all questions on fresh water.
This would also be useful for areas such as rural parts of central Texas, where the water table is so low that drilling a reliable well is dicey, the humidity is high, and the wind is fairly constant for most of the year.
For a small farm that tries to be as off-grid as possible, other than the noise factor from windmills, this would be ideal. If the water yield is good enough, it would mean irrigation is taken care of regardless of drought conditions.
I just hope this technology doesn't just fade away as many others have in the past. There is definitely a use for this around the world, as usable fresh water becomes harder and harder to find.
You haven't been here in July or August, have you? Dewpoints are generally between 50 and 65 degrees F during those months (although, with an outdoor air temperature of 110F, the relative humidity is still low). Currently, we have a relative humidity of 9%, and a dewpoint of 25F, so it's pretty dry, but an evaporator operating below 25F will still condense water...
And the worms ate into his brain.
no matter how many of them you install
No snowflake in an avalanche ever feels responsible
One has to wonder about the impact of several million of these, though. - One car doesn't do much polluting, but Los Angeles sure does have a lot of smog.
But what about the 2? Is there enough 2 in the Martian atmosphere??

As far C-3PO knows, the binary load lifters story is true. Shortly after the conclusion of Episode III, C-3PO contracted the Tyrell Corporation to wipe its memory banks and implant the memories of another robot. C-3PO effectively has no recollection of Episodes I, II, or III. Lucky bastard.
But if you kill the sandworms, you'll also destroy the spice.

No, they've invented vaporators.
The problem will be finding translator droids who speak Bocce.
The issue with many desalination plants is not the disposal of salts/minerals but keeping the system clean from all those salts/minerals. The issue being that salts/minerals have a tenancy to build up inside the pipes causing the system to need lots of maintenance.
Doctor Flamond: You see, a year ago, I was close to perfecting the first magnetic desalinization process so revolutionary, it was capable of removing the salt from over 500 million gallons of seawater a day. Do you realize what that could mean to the starving nations of the earth?
Nick Rivers: Wow! They'd have enough salt to last forever!
