Liquidate the Sahara

That thing has to go!

Off the coast of Libya, install a series of nuclear reactors. Don't tell anyone. This has to be done at night.

Across the straits of gibralter, install a hydroelectric dam. This may take a bit longer, you will need to distract the population with another game of thrones series.

Initially the tides, then a later drop in water levels, will provided electric power. Drop underwater lines to the nuclear reactors to provide backup power for cooling and regulatory systems.

At each reactor, is a pump and a nozzle that can shoot water throughout the troposphere.The prevailing winds in this area are northeasterly; the winds will distribute the atomized spray and fish-based nutrients across the western sahara.

Once this runs for 25-50 years, turn it off, dismantle the nuclear reactors, and retire to the lush jungles of Tamdjert, letting the refilling of the Mediterranean keep your lights on at night.

I suppose there’s more than one way to do it https://en.wikipedia.org/wiki/Sahara_Sea

       //atomized spray and fish-based nutrients // ... and salt.   

       Good luck growing lush jungles in salt.

       much easier to tow icebergs. and quite likely to be needed

       If you were to dig all the sand out and take it away the water would just flow in naturally under gravity, no need for the spraying thing.

       But where would you put it all? The sand.

       // where would you put it all? The sand. //   

       The Walrus and the Carpenter
Were walking close at hand;
They wept like anything to see
Such quantities of sand:
If this were only cleared away,
They said, it would be grand!
  

       If seven maids with seven mops
Swept it for half a year,
Do you suppose,the Walrus said,
That they could get it clear?
I doubt it, said the Carpenter,
And shed a bitter tear.

       I don't see why there is a problem where to put the sand. Think about it logically. A grain of sand is very tiny. If you go to the beach and come home with a grain of sand on your shoe and it falls off onto your carpet, it vanishes because it is so small.

       Ah but that sand grain doesn’t vanish. After a protracted series of unlikely events, it ends up in your stomach where it gradually turns into a type of pearl over many years. Jeff Bezos collects these human stomach pearls and has a long corridor with hundreds of them mounted in brightly lit glass cases.

       Don't tell me that, tell [whatrock], they were the one with the bee in their bonnet about what to do with individual grains of sand.   

       Anyway it strikes me that if there is such a demand for them from wealthy people the entire process (of digging all the sand out from the Sahara) could be cost-neutral or even turn a profit.

       You may be interested in Las Gaviotas, Colombia. Read up on it or just check it out on a map. They reforested a patch of desert.

       That was very interesting. Maybe terraforming does need a gentler hand then dumping a sea of water on sand.   

       Certainly the Salton Sea isn't the loveliest place.
