Surely there is a more efficient way of storing excess electric power than this?! Even pumping water up into reservoirs and then dropping again through turbines (like the UK national grid does in wales http://www.fhc.co.uk/ffestiniog.htm ) must be more efficient? Wont work very well in the Great Plains but most other places should have some hilly bits. MW
