By the late 19th century, America's Industrial Revolution was moving full steam ahead. This hall follows the development of the increasingly efficient power machinery that helped the United States become a world leader in industrial production during this time. Full-size engines and models illustrate attempts to harness atmospheric force (1660-1700), the early age of steam power (1700-1770), the development of high-pressure and high-speed engines (1800-1920). The exhibition also shows the evolution of steam boilers and the steam turbine and progress in the techniques of harnessing water power. A number of pumps, waterwheels, and historic internal combustion engines are also on view.
