That’s what Luke Skywalker did before running off to fight the empire.
Why do I see a Global Desiccation Crisis in our future?
It would have been a better article if the author would address if this item required energy input for operations.
This is what some arid regions have been doing for generations. If someone whats to dig them out, there are some images of a huge facility somewhere in the Mediterranean or off the coast of Africa.

Here is some computer graphics of the stuff. Interesting.
How much water do you have in your air?
Not much, too much hot air around me and coming from me.
This tech has been around for a while. Your air conditioner makes water out of thin air.
The writer lost me when he said that they collect dew from the air. Dew is a non scientific term for condensation that happens on humid mornings.
Sting likes it.
*snicker*
The structure can operate well enough using day/night variations. It would cool at night and collect dew in the morning as the air warms. No power requirement. It has to be very large to provide a significant amount of water.
As a kid when I was a boy scout they taught us how to set up something similar using your poncho & a hole to collect water overnight in survival situations. This is just an oversized version of that old technique.
But when I lived in Yemen, the 40°F temperature swings from day to night rarely produced dew clinging to any structure as there was next to no moisture in the air to collect. They may have done something to encourage the water molecule to cling to the material. Could be a similar concept to the mentos/diet coke formation of CO2 gas bubbles.
Beats wearing a stillsuit, Thufir!
If you are out at sea on a sailboat with no electricity (genuine purist) you might have rigged up a sheet of poly in that shape and got plenty of drinking water. It helps to be sitting over a large body of water. Probably wouldn’t be so effective in an arid inland region of dust and sand.
Isn’t this what the Boy Scouts teach when in survival training with a piece of plastic, four sticks and small rock? And this guy gets his PhD for it? Whoa!
Inspiration? I thought it relied on condensation!
I watched Survivorman do this very thing.
I remember reading about some pacific island years ago, where this sort of thing was the only source of water. Can’t remember the name.
