Ah thanks, I misread that. I get that these types of storages are inefficient, that's the point I was trying to emphasize, a solution like this looks interesting, but it's not a serious competitor to nuclear power, or even pumped hydro (it's basically pumped hydro, but with a human made reservoir). |

How can you say that off-hand without knowing what the costs are? It's not at all obvious to me that building 3000 concrete spheres with turbines and a bunch of PV panels is any harder or more expensive than building giant nuclear power plants.
