Default GE proposes to use artificial sink to generate 500 MW of power inSouthern AZ

I have to look at it from a conservation-of-energy standpoint. Where is the energy that is converted to electricity coming from?
The only answer I see is from the heat of the ambient air that transfers to the water droplets to evaporate the water, thus cooling the air, making it more dense. etc.
I'd be amazed if that is more energy than it takes to pump if up 2200 feet,(much less desalinate and pump from 50 miles away)!
Also, when the air passes through those turbines at the bottom, that's going extract energy from the air, and probably re-condense a lot of that water.. Are they going to collect and pump that water back to the top? The more they can, the less water they have to desalinate and pump from the ocean.

2250 foot high evaporative cooling towers to be used to generate power.
