This is the largest single-shaft turbo-generator in the world, recently installed in the Richmond Station of the Philadelphia Electric Company, Philadelphia, Pa.

It was developed by engineers of the Westinghouse Electric & Manufacturing Company, and manufactured in plants in East Pittsburgh and South Philadelphia.

The generator is driven by a steam turbine, the middle section of the machine.

The two U-shaped pipes carry steam into the turbine, which is simply a powerful steam-windmill with many blades.

The generator proper is at the right end. It produces 165,000 kilowatts; enough power to light simultaneously 6,600,000 ordinary 25-watt electric lamps, or one in every fourth home in the United States.
