- Westinghouse Transformer, Used by Rensselaer Polytechnical Institute, 1886-1889 - 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.

- Burden Water Wheel, circa 1900 - Henry Burden (1791-1871) built this water wheel in 1851 to power his Troy, New York, iron works. Situated on Wynantskill Creek, the massive, 62-foot water wheel powered machinery that created mass-produced horseshoes and railroad spikes. This image shows the wheel around 1900, after it was abandoned in the 1890s. Many still consider Burden's water wheel the most powerful vertical water wheel in history.

- Oldsmobile Motometer, circa 1925 - Automobiles often came without temperature gauges before the early 1930s, so enterprising manufacturers sold aftermarket motometers. Mounted on a car's radiator, these devices measured and displayed coolant water vapor temperature, notifying drivers if their automobiles were in danger of overheating. Moto-Meter Co. Inc. dominated the American market, producing the popular Boyce motometer and others featuring an automotive manufacturer's name or logo.
