Do readers remember Arthur Clarke's "Fountains of Paradise"
where a protagonist builds a bridge over Gibraltar?

Would it be a good idea to empty the Mediterranean Sea to have more land
Only inflows from the Atlantic keep the Mediterranean from drying up. If
you could actually build the fifteen kilometer long dam needed to plug
up the flow at the Straits of Gibraltar, it would only take a thousand
years to dry up the entire basin, and while waiting for it to dry out,
you can use the dam to generate gigawatts of electricity.
(It seems to me, that's a NO, if you are generating energy by
allowing water flow, you are not dyring it up!)
(The Nazis wanted to do it. But then they were also slightly nuts)
Not that the extra land would do you a lot of good, since the previous
drying of the basin left salt beds up to a kilometer thick at some
points, making it unsuitable for mass agriculture without a lot of soil
engineering. Which, honestly, would be better applied to non-arable land
that is already dry… and safe from biblical flooding. Because there is a
very real danger of tectonic movement destroying the Dam (Isthmus?) of
Gibraltar. And if you lift nearly four million gigatons of water off
that basin, you are damn well assured that those plates are going to
In the meantime, having all that water dry up and leave the basin
semi-permanently would lower precipitation (rain) around the basin,
further hurting agriculture. Not to mention the huge loss of fishing
stock. And the pesky issue of having global sea levels rise several
meters or so. (that water has to go somewhere….). Which means even less
liveable space for humanity, over all.
But hey, we’d be getting all that salt…
