The "Water Seer" came to mind the minute I saw this too, the amount of energy required to cool water in gas form down enough to transition it through to liquid form is immense, Just look at how long it can take a DE-Humidifier to extract a couple of liters from a room, and this is powered and also forcing air over a condenser

Thermal energy will pass from the hot to the cold side, you're also not cooling the cold side where the water is to condense, you need to create the scenario where the differential is enough to cross the dew point

This definitely smells the same as "Water Seer", the science will not add up. Can it get water from the Air, quite probably but 3 liters a day every day, and when there is only 20% humidity to begin with, that's a whole other story.

and how is the "Hot" air created by the black side going to travel Down hill to get to the colder side of the device? the black would need to be up top in order to get the sun, also by heating up the air, you will change its relative humidity (That's why its relative) and then when it is cooled again, it will go back to where it was

The Magic dust would have to be pretty special to overcome the conservation of energy laws!

The science is good, we just need to see if the technology scales and supports a cost effective implementation.

The approach is similar to a wind trap idea, where you move air with moisture through a structure where there is an enhanced environment for water droplet formation.

If you set the device up next to a good source of evaporating sea water, you could greatly improve its collection capability.

There's some sort of con going on here - what are the unexplained thick wires and heatpipes doing ?

These are not mentioned in the video or in your explanation.
