Isn't that called a dehumidifier?

And haven't these drinking water dehumidifier things been around for years?

Got one running in my house right now.  The collected water is really clean, but I usually just water the plants with it.

Yep. During the summers, mine will put out a few gallons a day. Water for plants.

Regular dehumidifier water is not safe to drink. Lead and tin from the condenser fins.

The system produces 250-800 liters (65-210 gallons) of potable water a day depending on temperature and humidity conditions and Kohavi says it uses two cents' worth of electricity to produce a liter of water.

Wow so I can  get 65 gallons of water for about $5....  Maybe some areas that might be cost effective but most not so much.

Actually, it appears out of thick air much better than thin air.

skozlaw: Actually, it appears out of thick air much better than thin air.


Actually, no. Humid air is less dense than dry air.

From the Wikipedia entry on humidity:

Humid air is less dense than dry air because a molecule of water (M ≈ 18 u ) is less massive than either a molecule of nitrogen (M ≈ 28) or a molecule of oxygen (M ≈ 32). About 78% of the molecules in dry air are nitrogen (N2). Another 21% of the molecules in dry air are oxygen (O2). The final 1% of dry air is a mixture of other gases.

Good. Ordinary dehumidifiers don't produce potable water.

Two cents where, exactly? Two cents of Israeli power, or two cents of Sudanese power? Because there's a huge difference. If the places that need water had access to reliable cheap electricity then they wouldn't need water because there are other ways to get it.

Also, there are consequences to taking water out of the air at one point instead of letting it fall out of the air at another point. Maybe with global warming freeing up some more water and making the air capable of carrying more water this will be a good idea though?

Why not?  Is there something in most dehumidifiers that taints the water?  I can see a filter causing problems, or the units being prone to mold, but the water it pulls shouldn't have any issues (anything in the vapor is being breathed anyway).

The water condenses on metals, mainly tin/lead, as stated earlier. Copper is safe, but too heavy/expensive for the cheap dehumidifiers you can buy in a store.
 
2014-04-28 02:10:37 PM  
It's not that they made a condenser, which no one had made before. It's that they made one more efficient, and one that produces CLEAN water (as opposed to just "water" of dubious potability).

And to those asking, imagine Southern California's water shortages affecting 7+ million people, most of whom do not have anywhere near the kind of money or political clout of Southern Californians.

// there's also the problem of backwoods farmers in the region insisting on using flood irrigation, which wastes lots of the water they do see

the air handler for my house AC is located in the attic, so I attached the drain pipe for the condensation pan to a 55 gallon food grade drum.

yep, use the water for the garden.. it'll make up to 5 gallons a day easily during the Virginia summers.

The CLEAN bit isn't new either (2001 article). Maybe this one has better efficiency, but more likely it's just a corporate press release being copy/pasted as "news".

Certainly a possibility.

Photo looks shopped (or it's the way it's compressed for Fark) but basically a dew collector. Water drips out the bottom in to some form of collection system (jar, etc.).

Um... This is exactly how some of the commercial disaster recovery dehumidifiers work, including pre-treating the air before running it through the coils.

If this company's glorified dehumidifier is sooooo efficient, how come we're not seeing them selling it in the dehumidifier market?  My guess is that it's a bunch of bull.

It's a WarkaTower.

They don't work in regions without fog or humidity, but if you've got those you can get several litres of condensation gathered per day.  They would work quite well in the coastal areas of Namibia or the Atacama Desert in Chile.

That could make a difference. I've known a couple of people who have filled their fish tanks with tap water, but would let it sit for a week or two with no lid to let the chlorine and other chemicals evaporate.
