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?

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
