Atlantropa was a gigantic engineering and colonisation idea from the 1920's. It involved building humongous hydroelectric dams and lowering the water level of the Mediterranean by something like 200 meters.
I want to ask whether that plan would have been possible, remotely feasible or just crazy.
Is this question suitable for any SE site at all?
What is the best site to ask it at? I have considered Earth Science and Engineering, but I'm not familiar with either site, so I'm not sure.
