These dehumidifiers produce half a liter a day and need around 72 watt which is maybe 1€ per liter drinking water for my area The tech is cool but not really new or a solution to all water problems, the energy cost is relatively high.

AC does it as a side-effect of cooling the interior, but it's still a miserly amount not worth capturing.

Dehumidifiers come in a variety of capacities. Extraction of 4-8L per day with a 400W power consumption is typical, more if humidity is high. Larger communal units would be more efficient. If you have abundant power literally coming from the sky, why not use some of it to make clean water? https://www.amazon.com/s?k=dehumidifiers+for+home https://www.amazon.com/s?k=dehumidifiers+for+home

  They are far from an abundant source of water, like you said. Taking 400W *24/7 is quite a lot of energy, and I'm not really believing the 4-8L output. At 17° Celsius and 38% humidity, you get 0.008g of water out of 1L of air. There are physical limits to this, of course. The dude in the video does the calculations, and it's far from "no problem to make water out of air". It would be better to use the energy for something else. If it was so easy to do, there would be no problems with water shortages around the globe (and soon maybe "water wars") just take it out of the air with solar.
