I don't know how much loss does it amount to on a sunny day.

- Tloewald 13y agoThis is in fact the entire principle of hydro-electric power (incidentally, a form of solar power since the water-cycle is driven by heat from the sun).

- kijin 13y agoMany pumped-storage plants just dam an existing valley to create the upper reservoir. Easier than trying to build a gigantic swimming pool on top of a mountain, and probably safer as well. Of course, in order to do this, you need some very rough terrain, so it's not suitable for flat countries.
