[modeleng] Re: Semi OT windmills / generation

Down near Chattanooga Tennessee, TVA hollowed out the top of Racoon Mountain 
and put turbines at the base.  When the demand for electricity is slack, they 
pump water to the top of the mountain.  When demand is heavy, they generate 
electricity by letting the water run back through the turbines.  That, plus 
their hydroelectric facilities, plus some gas turbines allows them to keep the 
nuclear and coal-burning steam power plants running full speed while helping 
meet peak demand loads.  Charles
