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.

Combine salt and water to create electricity to power a desalination plant that removes salt from water. I am sure there is more to it, but the article sounds like it’s one of those mad perpetual free energy schemes that defy the laws of physics.

    They are just re-capturing some of the energy the system spent turning salt water into fresh. Because that results in extremely salty brine water waste, you can get some energy as it gets diluted back down to sea water concentration.

    There no “new” energy in the system, it’s just wasting less.
