I sounds more like it makes electricity out of fresh water, destroying it in the process (turning it into saltwater through osmosis/dilution). Sure… if there is some crazy salty water you have, and want to turn it into “still salty, but maybe less so”, you can indeed gather a tiny little fraction of the power.

But given that fresh water is also a precious resource in many places, this seems relatively niche.

Presumably they do what Visa/Mastercard should have done, and tell them to shove it. It’s just a bunch of uppity idiots from Australia, no one HAS to listen to them…
