That's it? Nothing else. Seems half written.

I saw these as well. I wonder what it does to arid areas by pulling the moisture from the air. Concrete blocks runoff so it evaporates on the city. Could it be viable? I wish I had $2k for one of these.

Yeah, but first you have to work them down with like three electric types because their HP pool is so big.

Aww. I was going to Toshi Station to pick up some power converters...

Across the region, temperatures are rising and droughts are getting more severe, and in the coming decades the West will struggle to supply the water its residents and businesses demand.

You know this is eventually going to lead to ice piracy...

No, humans also need food and air.  Water has zero calories.

My dehumidifier does a good job and I got it for $30 at Walmart. I'm not drinking the water that comes off of it without boiling it, though.

No. You're going to need a little oxygen every now and then that isn't bound with hydrogen.

Yeah. But next thing you know a Kwisatz Haderach comes along and there goes the neighborhood.

Oh, it's germs your worried about... Go the extra distance and distill it. On second thought, forget about the water and distill fermented corn mash instead... To achieve maximum antibiotic properties in a fluid, of course.

I figure I could brew some beer with the water it produces with no boiling. If I get alcohol, we're good.

How do you brew beer without boiling?

Just checked this out from my library. Haven't seen it in probably 30 years. Yet another movie my wife will look askance at me and wonder how I liked it.

You boil the ingredients together and then you ferment. But, you're not boiling and recovering anything like you do with distillation. ("Distilled spirits")

I think that was an ad. Where's the farking pictures of the rig in the truck? It doesn't exist yet, they're setting up for more Kickstarter fraud.

Elsewhere I read that the Israelis (possibly others) can desalinate water for less per gallon than I pay in the middle of a non-desert.

With fractional distillation you do not want to boil your liquid.

There is a way to slow the amount of infections down.

I would like to see an independent performance study, or at least an energy balance, on these panels.  Seems to me they violate conservation of energy.  Scam alarm has been triggered.

Vaporizing. Boiling. They're exactly the same except for all the differences. And now (where I am, YMM(unfortunately)V) it's time for booze brought to you by fractional distillation.

/You are right. And I am wrong.

Am I the only one who has no sympathy for people living in the desert? It's an inhospitable place that takes an excess of energy to cool and hydrate. The green lawns of Phoenix are a great example of exactly how wasteful we are, then start pointing fingers at politicians and energy companies. I mean they're partly to blame, but no more than a geezer in the desert that gets their water from hundreds or thousands of miles away to water their farking lawn.

I'd dabble in the idea of running sea water through two sets of evacuated solar collection tubes. After the first set, separate the vapor from brine, run through the second set to run a turbine, then cool in a heat exchanger with sea water.

Depends... If people were to work with the environment, it can be a very interesting thing to see - xero-culture landscaping, use of the earth to heat sink, water collection and recycling...

But places like Phoenix or Las Vegas? No sympathy.

Coober Pedy FTW.

Although I've yet to visit... But it would be an interesting gardening challenge...

Seems like a promising technology.  Yes, I see all the fark engineering PhD naysayers are here.  But still, promising.

I think what they're doing is using a hygroscopic material like silica gel at ambient temperature to adsorb water vapor from the air, then heating up that material with solar energy to release then condense that collected water.

Makes sense, but the condensing part would need to rely on cool overnight temperatures.  So, no workie, unless things cool off at night.
