There are strong currents at work in the strait of Gibraltar. Would be interesting to harness their energy in some way.

Agreed. There's a tidal turbine off Orkney, the most powerful in the world, that just went live: https://www.orkney.com/news/orbital-grid It's powering 2,000 homes and an electrolyzer creating green hydrogen. A few of those - or a few arrays of them- in the Strait might do wonders.

Japan is apparently going to give it a shot: https://www.inputmag.com/tech/japan-kairyu-ocean-turbine-dee...

Looks like Scotland’s is a roaring success: https://www.bbc.com/news/uk-scotland-north-east-orkney-shetl...

No need to evaporate the sea.

This also draws energy out of the sea, a net positive for climate change mitigation.
