More efficient water from air using high voltage

New video I found interesting.
The short synopsis: 2ft section produces 539ml of water per hour and consumes 40 watts.
 He compares that to standard dehumidifier that consumes about the same amount of power but produces only 60ml per hour.

Plus, this version is designed to be installed directly above row crops.  Pretty cool


Also, I'm thinking high-voltage wire also serves as a great deterrent for creatures attempting to eat said crops, so win-win when it comes to function stacking.

This and other similar methods like mist nets are only going to be worth the trouble in coastal deserts like the Namib and Atacama, where fog is common. No amount of high tech is going to wring any appreciable amount of condensation from air in inland regions like the Sahara, south and interior Asia, Australia, or the American West.

Another place where this could be useful is coastal regions that have a Mediterranean climate. Anywhere in California that sits under the marine layer might be a candidate.

A similar concept was planned for the city of Capetown in the 1940 s by Theodore Schumann to produce water n the mountains and use it to produce hydro power electric as well to part recover its energy requirements based on patents from Alvin M Marks, it was called a power fence ---but on a large scale and size----of course it never happened and Capetown still goes through droughts and water restrictions.

Hubby watched it and commented that he was using artificial heavy fog. Fog is actual droplets, whereas humidity is a gas. The 2 are not comparable.

We have dry summers and live right near an ocean, but rarely do we get fog in the summer. The places that have the perfect conditions, as Phil pointed out, may find it helpful, but fog is relatively brief in many places, so it still might not produce enough moisture to sustain many plants.

Now you're having  to keep the wire live all day, just to collect a bit of water in the morning. That's going to change the power to product ratio. It will also depend on what sort of critters you're trying to discourage.

In the desert I've lived in for 30 years (Indian Himalayas) there is rarely fog, except maybe during light rain, so maybe for a few hours on a couple days a year. And the air just isn't holding a lot of humidity that can be condensed out of it.
