I've see one application that actually worked and wasn't 100% hype. It was pretty specific conditions, some political. I'm sure their might be two locations is works, these BBC examples are not them.
This always goes to Dune and generic removal of water from the air, Thunderf00t talks on youtube about actual physics involved around collection of water from the atmosphere and how it's not possible if you're interested why this can't happen.
It only can happen around the ocean where it's pretty much rain, but it doesn't rain and the saltwater contaminates the water supply and you own rich sea side housing but can't pipe it in from a near by town.
If there is a working application of fog nets feel free to post a link with actual photos and number of litres recovered. That would be a big deal to leave the "we want money stage" and supply real water. So there will be studies if it's real, that we can read.
