LARGER MERCURY VAPOR ELECTRIC GENERATING UNIT BEING BUILT

A new and larger turbine electric generator that will use mercury vapor instead of steam and will consume less fuel than corresponding modern steam plants is being constructed in the General Electric Company plant at Schenectady, N.Y.

This 20,000-kilowatt turbine will have twice the output of the mercury vapor engine and generator that General Electric engineers claim has already proved its superior efficiency over steam turbines during a years test at Hartford, Conn.
