This is recent; but now very new. I saw it a while back like 2 month ago.
Israel plan to build this Sneh Aero-Electric Power tower in desert. They pump water, any water including sea water, to top of tower and mist them out, cool the hot/dry desert air and cause down draft. Cool air exits out at bottom tunnels and turns windturbines on the way out to create power.

Again, I am not sure where I read it, maybe here; I did search here but come out empty.
