Another problem is that the water doesn't taste great.

Also, I was about to post a concern about distilled water possibly leaching nutrients from the body, but a quick google reveals the opposite may be true: https://www.nutriteam.com/distilledleach/
Or in other words, this thing only makes water when you probably don't need water.
Blow some nice 90 deg F 20% humid air past those coils, and you'll be blowing out a lot of 80 deg F 25% humid air out on the other side, getting bupkis for actual produced water, but sucking down plenty of juice. Slow down your intake fan to almost zero, and now your water produced goes up from zero, but the slowest of trickles.
Gotta love all that ozone generator carbon filter garbage on the business end. It's all just bells and whistles to put lipstick on a three-legged pig.
I might be way off base here but is that Jim Mason - Founder of All Power Labs? In that case it hints that gasification could be part of the solution.
As I understand it, it is basically the skysource water extraction device hooked to an all-power labs gassifier, which produces electricity from gassifying organic material. Allpower's product uses the gassifier output in a conventional engine, in turn using that to power a generator. The great part here is - uses locally generated biomass, and produces a waste stream of biochar, which can be used for argiculture, es…

I think the approach is a bit more novel than normal dehumidifiers. Instead of just collecting water dripping of the condenser coils, they use the cooler air to make a "rain chamber". The website talks about "maintaining a dew point within a condensation chamber".
This sounds like Persian Wind Catchers. https://en.m.wikipedia.org/wiki/Windcatcher There's a similar type of building which uses temperature difference to generate condensation within a building, creating a pool of water. The name escapes me at the moment.

That's a pretty apples-and-oranges comparison. That's a company making ridiculous promises (look ma, no external power input!) and without any third-party verification. This is a company that makes realistic claims (i.e. has actual numbers for power input per liter of water) and whose performance has been verified by the prize-awarding organization.
> has actual numbers for power input per liter of water Where did you find that? All I could find is "0.8-1.8kW/hr" for a machine with capacity with a capacity of "30gal/day". This is complete nonsense, "kW/hr" is neither energy nor power nor energy per volume of product. And if it's power, why does it vary? I'm going to read it as 1.8kW, with a capacity of 30 US gallons (113l) per day. My dehumidifier from the hardw…
It varies, as does output, because (as the numbers mention) this all varies wildly by atmospheric temperature and humidity.
(By the way, running the numbers I'm seeing it as 62.77L/kW vs. 50L/kW, which is a 25% improvement, though at much larger scale.)

They have commercial models for sale that produce half the competition amounts, and have pretty detailed specs online: http://www.skysource.org/products/
Those specs mention producing half the competition's amount in optimal conditions, which I assume means 99% humidity. They don't actually say at what humidity level and temperature their product can deliver that much. They don't give any specific numbers at any specific temperature, only the machine's operating conditions and the upper limit on what it can produce.
It’s an overpriced dehumidifier. Pulling humidity out of the air. It’s not magic. It’s not new. There is water vapor in the air, every middle schooler knows this. They are in Hawaii. An outdoor dehumidifier will work great in a water abundant area. How well do you think a dehumidifier will work in a low humidity area? The places that need water the most. It’s not making water, it’s pulling out the humidity. This is s…
The ignorance in your comment is truly astounding.

the wind traps, from Dune?
Is this another one of those dehumidifier machines that promises it can deliver gallons when using a tarp, rope, and a bucket to catch rain water collects more water per year?
RTFA, especially before snarky dismissals: "meeting the competition parameters of extracting a minimum of 2,000 liters of water per day from the atmosphere using 100 percent renewable energy, at a cost of no more than two cents per liter"

I think the key difference is that "Skywater machines use a patented Adiabatic Distillation Process, where water vapor is reduced to liquid without a gain or loss of heat." so it's a little different than just a regular dehumidifier. It also seems to be able to pull a lot more water than a normal dehumifiier? "Skywater machines are ranging from Skywater 30 (up to 30 gallons of water each day) to Skywater 300 (up to 3…
The prize requirements limits costs to two cents a gallon, it looked like, so can't be all that bad in the energy front.
