BBC News: Molten metal batteries for the grid

[fgentges at mindspring.com]

There is another water based system in Missouri.  It is the Taum Sauk 
Hydroelectric power station.  It was built in 1963 by Union Electric in 
St Louis. It suffered a major failure from a hurricane.  More 
information on this is at:

Another project by Union Electric is Bagnell dam which was built in 
1929-1931 prior to the TVA project.  It created Lake of the Ozarks, a 
favorite recreational area.

Both were done on private money by Union Electric.
