- Operating a 100,000 Kilowatt Turbo-Generator at the Ford Rouge Plant Main Powerhouse, June 1934 - The powerhouse at Ford Motor Company's Rouge factory was readily identified by its eight tall smokestacks. Steam turbines, fueled by pulverized coal, generated electricity for the massive Rouge complex -- and for Ford's Highland Park and Flat Rock plants, and for Lincoln's Detroit plant. The Rouge sometimes generated surplus power that could be sold to Detroit Edison Company.

- 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.

- Westinghouse Type A Wattmeter, circa 1903 - In the late 1800s, companies that supplied electricity to consumers needed a way to measure how much customers used -- and then charge them accordingly. Inventive electrical engineers developed various methods to measure electric power. Induction meters that employed magnetic fields to rotate a disc or cylinder to register energy usage would become the standard. Continued improvements made these wattmeters more compact and reliable.
