- Eickemeyer Dynamo, Used by the Haxton Canning Company, 1889 - Rudolf Eickemeyer developed his "ironclad" dynamo in the 1880s. The unique method of construction--its heavy iron field coil construction and iron sheathing--gave the dynamo its nickname. It was compact, rugged and efficient, though the ironclad design made it difficult to cool. This dynamo supplied power for the lighting system and small motors at the Haxton Canning Company in Oakfield, New York, for 15 years.

- General Electric Thomson Recording Wattmeter, circa 1903 - Elihu Thomson, engineer, inventor and cofounder of the Thomson-Houston Electric Company, developed a commutator-type wattmeter in the late 1880s. His recording watt-hour meter helped transform the nascent electric power industry. The sturdy device provided companies that supplied electricity to consumers a way to accurately track and bill electrical power use.

- Federal Electric Company Transformer, circa 1906 - Transformers increase or decrease voltage and are essential to alternating current (AC) power systems. In the late 1800s, with the help of transformers, AC power systems proved more efficient and economical than their direct current competitors. Transformers helped convert electricity to high voltage for transmission across long distances, then reduced it to lower, safer voltages for use in homes and factories.

- Short Circuited Rotor for Experimental Westinghouse Induction Motor, 1889-1893 - Nikola Tesla's name is inseparable from the development of alternating current electricity--particularly with regard to polyphase transmission, but especially with regard to the induction motor. His motor, patented in 1888, was the first practical AC motor. George Westinghouse licensed Tesla's motor patents that same year--enabling the Westinghouse AC lighting system to become a real competitor with direct current systems.
