The old Edison and Tesla battle for AC or DC current!My Grandpas son in law Was a PE for PG&E on the project for the lake and Turbine method of energy storage. Among other things for PG&E...
The Chinese have extensive experience running battery farms alng with Solar and wind arrays.... I was reading on them just recently... One of those batteries can supply a grid of homes...
