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.

DIG, BABY, DIG!!!



Arkansas is notoriously lax with Environmental Protection, so I expect the Strip Miners will have a field day with the Caterpillar Back Hoes and Front End Loaders digging through all the topsoil in this region to get at the Lithium.

Of course, they still need the Diesel to power the Caterpillar heavy equipment.
