I'd never go in on a looting because I'd be the guy robbing Nordstrom's who gets away with a piece of carry-on luggage. 

Yeah he might have used it to carry stuff but it looked pretty light.

Actually, decades ago Arizona realised that there was more economic advantage per megalitre of water in cities than in cotton. So they shifted their policy to favour expansion of Phoenix into the monstrosity it now is. Actually, I liked visiting Phoenix but it should be about 1/4 the size.


Loved it. Came back there in the early 90's. Travel-guides from Europe were already asking the question then, no holds barred. Gulf courses and all. Lush green parks... sprinklers at night in front of bars, restaurants... (120 degrees, musta been a hot day) every house, apartment-complex having their own pool in the middle of a desert, AC's burning to their limits, etc.

Which reminds me of the Fire Department, banging on my doors, late one night... 
Me opening the door (somewhat scared), and the men telling me, my car in the parking lot be leaking gas.
However, they'd fixed it (my leaking gas tank) with a sort of chewing gum. (My dad had loved it as a first-aide from US GI's as a kid.)

To my great relief it worked, and I kept my '73 Pontiac Catalina SW until I had to leave (not without exchanging the gas tank later), and finally selling it way under-priced. Taking it home to G would have been a road to hell, financially, which I've started doubting during latter days, due to a hype of old-timers, but hey...

Dealing with the brine is a huge issue for all desalination units, and it compounds over time. It's fine for tiny applications, but even at household size it's difficult.

In warm wet air, appalling. In warm dry air, even more appalling. In cold dry air, not even feasible.

I've worked on two such systems, one commercial (for household use) and one military. The military unit came on a trailer and used a desiccant approach (like a large HVAC dehumidifier) which extended its operating range but it was still a huge energy pig.

For some situations you can justify it: remote military operations in dry country or disaster relief. The military looked at it like this: it cost them about the same to truck a gallon of water as a gallon of diesel. If you can make more than a gallon of water from a gallon of diesel it made sense to just truck one kind of fluid.

For solar applications you can sort of kinda justify it as long as the solar power has no other use. It takes a lot of area of solar panels to make significant amounts of water, and this precludes running at night when they're more efficient.

There have been lots of demonstration projects that made a trickle of water out of a lot of energy. The commercial product I worked on (turn of the century) and all its contemporary competitors are all out of business. This idea just won't die, much as it deserves to.

There are niche applications where it does make sense. As you noted: solar. Solar is difficult because you have to build for peak load, but you often don't use it, so you have excess that can be routed to things like this. The model we are working on runs on about 20 amps of 240 most of the time, so 5KW. with losses conversion ect.  call it a 7.5KW array (most run time will be in full sun). But the system is going to have 10KW of array, and it's a storage system (battery), so depending on conditions we can kick it on at 4:30 AM when conditions are prime and run it for a couple of hours until the sun starts to make up power. Then we shut the water system off at noon to allow AC loads and battery charging, then depending on loads we bring it back online in the afternoon.  It's not going to meet the needs of a city, but it can meet the needs of a household. The solar footprint is 28 panels that are ~4x8, but placed on an angle, so well under 1000 ft^2 with mounts/rigging/walkways, and most of this will be on an unused rooftop (so it shades the roof as well).

That does sound like a lot. If i recall correctly, a typical panel produces between 200 -500 watts?
Thanks.


Panels come in all kinds of sizes, but optimal right now is about 400Watts and cost is ~ $0.50 - $0.65 per watt. 

I grabbed the wrong line on my spreadsheet before (mid coffee, sorry), it's actually 15-20KWhr/ 40 gallons.  There are different sizes and you can play around with scale and run time depending on your application. We are trying to get something that will run on excess solar production during the day to make enough water to sustain a household. Problem is at peak production for both water and solar, you want to run air conditioning in the house, so it's a balancing act of finding the margins.
