But with solar you only have maybe 10 hours of generation per day at best, so you need to store the energy ( which has inefficiencies) or a grid that can cover many timezones. Using stored water for potential energy means it can be turned on and used as needed, and rated for an average use. In Australia there are plans for more stored energy systems using pumps and generators, probably fed by solar and wind.
- usrusr 9y agoStored hydro isn't the realm of vortex turbines because they cannot be reversed, and because they excel at high volume/low drop. Pumped storage prefers high drop/low volume because losses from evaporation and seepage don't scale with height. Vortex turbines are for tapping a creek or the canals left behind by a pre-steam ways mill that would otherwise be uneconomical to harvest, or where ecological impact of other installations would be too high.
