I'm a bit irked that a technology of this significance has no videos or demos or actual use cases, just a PR blurb. Is it confidentiality, or is it too early stage? Otherwise X Prize becomes another congratulatory event. This feeling seems to run through the entire site as I click around.

Do you have a source for that?

The company itself has a website at http://www.skysource.org/
You know, there are places where water falls out of the air on its own, and if you don't spoil the hell out of the landscape you can even drink it. Give it a rest, humans.
From what I can glean online, the 150 gal/day unit costs $18k usd + $150-$300 in electricity a month if run 24/7 at $0.10Kwh. Ignoring electrical costs, it would take 1581 days to reach $0.02/liter. In that time you would use up $7.5-15k in electricity.
The best estimate I could find is that the average US household uses 240 gal a day.
A friend of mine had to drill a 980 ft well through bedrock. A well this deep requires a much stronger pump and more electricity. They are on their 2nd pump. I should ask them what that all cost.

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.
I'm not endorsing it, just posting, i have not yet see the video.
2 cents a liter is not close to feasible for any sort of agricultural or industrial use and is an order of magnitude more expensive than residential tap water. Seems like cool tech, but I can't see how this is a solution to any type of water shortage.
Does anyone have any details about their actual technical implementation? I'm sure it is interesting. I imagine it doesn't look too similar to a Tatooine moisture farm.
1. They’re in Hawaii. It’s a little humid there. So... yea. Dehumidifiers will collect quite a bit of water in a water abundant area.
2. The places that need clean water typically have low humidity as well. To pull water from air, there needs to be water in it.
Think of this as all those folks that claim they can run their car on water as a fuel. The thing they fail to mention was they were using a battery to split out the hydrogen from the water to use that as fuel. Which is not more efficient than just using the straight up battery.
This is a publicity stunt scam. A real shame too. That money would have been better spent on education or better water infrastructure in places of need.
