There's discussion of something to stir both reservoirs to keep the mineral particles from settling. Which seems rather energy-intensive and wasteful. There's no specification for what kind of minerals or surfactant, or what kind of properties they'd need to have. No discussion of how to pump an abrasive mixture without lots of expensive maintenance. It, frankly, sounds like they're saying "sand!" What happens if the surfactant leaks or there's a dam break? The scale of disaster from something like this is pretty insane; they're proposing what amounts to a ready-made mudslide behind a dam. There's also discussion of using the water to cool the generators, like that's somehow novel...and for some strange reason, heat pumps and geothermal heatsinking? This feels like patent trolling. It reminds me of crazy-board-of-string-and-photos meme guy. "OK, so we have a hydropower plant! BUT, BUT, we put SAND in the water! And and we need some things to stir the water to keep the sand in suspension. We can tack on this geothermal well! And cool the pumps with the water!"
