I'm a total newbie at climatology and geoengineering, so please, no judgement.

I had a simple idea when thinking about how awesome it would be if we could terraform the Sahara desert (or just some parts of it). It consists of a long pipe going down into the Sahara's large aquifers. With a water pump, the water would be pulled upwards and heated over boiling point, then, the steam would be expelled, go up the atmosfere and form clouds. If it rains, the rain would seep into the ground and refill the aquifers.

The problems I can detect are the possibility of the steam being carried out of reach by the wind or not even condensing at all.

Would this work? The fact that I've never seen this idea floating around before makes me think that it wouldn't.
