It’s not -a lot- of electricity … a couple of thousand kWh per day. It’s also used to de-salinate ocean water … of which there’s plenty.

If they’re mostly using electricity or even combustion to evaporate the water (as opposed to sunlight), there’s no chance that the concentrated saltwater creates more electricity than it costs - it’s only maybe useful if the saltwater is actually a waste product.
They’re using brine from a reverse osmosis plans and wastewater, so yes, that is indeed the case.
Far cry from “perpetual free energy scheme”, though.
I don’t think anyone claimed it was.
It seems like every other top level reply in this thread is people poking holes in it based on their personal speculation about the details.
It’s the misleading “generated” electricity headline. It just re-captures some of the spent energy to be slightly more efficient.
