Ultrasonic foggers would also increase the amount of salt in the air, so you’d have to run them far out in the sea.

Instead, flood Death Valley with ocean water:

1. Massive evaporative potential. 2. Moisture trapped by tall mountains replenishing the aquifer and making lush surroundings. 3. Massive hydro potential 4. Displaced species not seriously harmed since the moisture gradient would be large (are P. 2) 5. You could harvest the salt prolonging the suitability of the project (anyway measured in centuries if not millennia)

Basically you’d have the lushness of the surroundings of Salt Lake City (compared to the desert anyway). Except there would be a lot more moisture (lower salinity wrt it Salt Lake, moisture better trapped)

You could do the same thing in Egypt at the Qatara depression, except with potentially global benefits. Here the half of the Sahara could be turned into productive farm land.
