Yes, even though they are not optimized for it, and often handle the produced condensate in ways that make drinking unlikely, refrigerators and AC units can produce condensate that might be filtered, or otherwise treated, and drunk.

uh, since you are unlikely to have power if you don't have water, how are AC or frig going to help?

yep, that sort of attitude is EXACTLY why the world is overpopulated. Everyone considers THEIR genes to be oh so special.

My fallible interpretation of the thread is what can you do when cities begin to run out of water, as well as when cities have run out of water.

Out of water does not necessarily mean out of power.

Just as you may want to plan to be able to generate water, you may want to plan to be able to generate power.

If you have power, it might be useful to know how to get water-from-air using your existing technology.

of course one = the other. Without water, people will have left the area, so who will be generating the power, hmm?

I suspect that when water shortage really begin to crimp places like LA, Tucson, and Las Vegas, you will see conditions developing akin to those we see in the Rust Belt cities of the northest, most notably Detroit. In this scenario, there will be a gradual decline in population, not a catastrophic, Mad Max rush for the exits.

One of the advantages of Detroit is that the area possesses abundant water. So if you are really thinking ahead.....

I really doubt water shortages are going to change anything in the near term. Probably not in my lifetime. LA doesn't have much natural water. But it is a population and profit center and it has both the wealth and political power to have water channeled to it. Which is a major reason it became a large megalopolis.

Las Vegas is another city that has water issues. It has essentially no natural water. Hasn't seemed to matter because the money and political power deigned that it would have plenty of water, cheap. Fact being that Las Vegas flaunts the incongruity of its existence. It is like there was a bet made that a person could build a prosperous city in the least likely place imaginable. A place with no water, not really along a well traveled route, a place where no food is grown, and there are no jobs or natural resources to exploit for jobs. Fact being that the place has absolutely nothing going for it. So they built a city. Just to prove they could.

As water gets more scarce and prices rise there will be increased pressure for conservation. There are a lot of places to save water. Especially considering that about 20%, by some calculations, of water use is wasted in leaks. Then there are lawns and golf courses. But there are people still harping about how their ten-gallon-a-flush toilet and high-flow shower head is a God-given right. That low-flow toilets and shower heads are infringements on their civil rights.

The history of money, population and politics all tell you that LA and Las Vegas will get what they need, as long as the money holds out. Massive water projects allowed both places to thrive. Does anyone doubt they can/will not do it again?

LOVE IT!

What would be really interesting (since I'm not there) is what would happen to those two megalopolises if the water got turned off really fast, as by terrorists or an earthquake.

I imagine they will, so long as money is enough. If/when the reservoir drys up and the water simply doesn't exist, or can't be routed there for any sane amount of money...well, then things will get interesting real fast. smirk
