Energy Storage Solutions

[RE]

New thread for energy storage, focusing on methods OTHER than batteries, particularly Li-I, since we all know about the pollution problems and resource scarcity issues attached to heavy dependence on this chemistry.

I really like this one because it's fundamentally very low tech and doesn't require microprocessors or complex systems.  Basically just a big spinning wheel with high mass and low friction which allow it to  keep spinning until you put a load on it to generate electricity.  Along with gravity systems like stored hydro, it's a great way to balance the load with intermittent generating systems like solar and wind.
