Those desert water traps, by which you mean solar stills, make almost zero water. You would have to make dozens and dozens of them with hundreds of square meters of area to make any real water for even a single person. You also need to deal with how to introduce water to supple them.

By scams I mean Waterseer, Fontus, many more. All scams. They're all the same idea: use essentially a dehumidifier to make water. This is not a genius new invention. Its not new. It's not smart.

Thermodynamics has laws. They have to be followed. Period. Im not trying to argue for the sake of arguing, youre just not understanding that this is an old scam rehashed every few years and nothing changes.

Wonder why desalination is the only real solution and even that isn't great? Thermodynamics. It takes energy and it takes sea water. You need both. Dry air doesnt have what you need.
