Battery Let MIT Solve The Energy Storage Issue

The electric company built a huge battery about 45 miles south of me, about 40 years ago. Don't know how many megawatts capacity it can store but I wager it's a lot. Used to be recharged with coal but now they use wind.

There's no electrodes to wear out or electrolyte to catch fire. Just water pumped up hill by wind and when they need more juice let it run downhill through the turbines.
