Is this type of tech a hoax or it is really thing that was not considered enough for the upcoming water crisis around the world?

I think it's all about energy efficiency. Places with no access to clean water often also have no access to reliable energy sources.

Your gut is right. After a quick search, it seems that the power consumption of a seawater desalination process is less than three kilowatt hours per meter squared for a large-scale plant.
However, the downside of desalination plant will be the cost of the infrastructure and the time it might take to have it up and running. With the "water extraction from air" machine, the cost is lower(I assume) and the size is smaller(Height: 259 cm, Width: 610 cm and Length: 224 cm). Seems like it might be quick to have this MoP up and running faster than the desalination plant while costing a ton of energy in the long run.

After checking this dude's website, it needs 475 Kwh/m3 in a desert condition which is a lot of energy.
With this in mind, using the data within this website, to achieve a daily 100 kWh electricity output, the people interested in this device will require 50 to 52 solar panels, each rated at 400 Watts. Now, if we multiply this times 5, they might 250 solar panels to deliver that kind of power.
In a hypothetic scenario, what could be done to make this practical?
Unfortunately, nothing really. The thermodynamics are just severely unfavourable. Water is an amazing coolant, by far one of the best. It takes up an insane amount of energy to vapourise. That Unfortunately also means it takes up a lot of energy to turn it back.
It would make more sense to focus on developing conventional technologies and reforestation in the Sahara. That path is a lot more viable
