Water poured into his system would, in theory, turn a wheel that would power a pump that would cause the water to flow back over the wheel that would power the pump, and so on.

Like its bigger competitor, General Electric, Westinghouse spraddles the entire field of electrical equipment. At its tremendous East Pittsburgh works it can make anything from waterwheel generators for Boulder Dam to complete power and control apparatus for steel rolling mills. At Derry, Pa. and Emeryville, Calif, it fabricates porcelain insulators. The Chicopee Falls (Mass.) plant turns out radio equipment. The Newark (N. J.) plant manufactures metres. Power transformers and transmission equipment are produced at Sharon, Pa. Diesel-electric units, steam turbines, marine reducing gears emerge from the South Philadelphia works. A Long Island City (N. Y.) plant specializes...
...impounding 530,000,000,000 gal. of water and having a 700-mile shore line. The bits and bridles to govern so much potential power were told about last week by the General Electric Co. at Schenectady, N. Y.: three electric generators, each driven by a 45,000-h.p. waterwheel turbine. Alabama industry will point proudly to the largest power units in the South, the second largest* in the country...
