A steam engine is a heat engine that performs mechanical work using steam as its working fluid. Steam engines have a long history, going back almost two thousand years. Early devices were not practical power producers, but more advanced designs became a major source of mechanical power during the industrial revolution. Modern steam turbines generate about half of the electric power in the world.

"High volumes of steam were pumped into the hollow sphere. The steam would then escape through the many evenly spaced arms around the center of the sphere thus causing the engine to rotate." —Quackenbos 1859

An illustration of Newcomen atmospheric steam engine. The boiler heats the water to build up steam in the piston. While the steam lever closes, the water is let in, and the piston compresses the steam to generate energy. The compressed steam turns to liquid, and opens the steam valve.

"This term is applied indiscriminately to evaporators with steam-pipe, whether arranged in the form of a coil, or, as more commonly used, in a rectangular series, In some the steam is admitted through a main pipe, from which others lead off at right angles, terminating in a similar main, which receives and carries off the condensed water of all...Still another, and the most convenient plan, thought not without some objectives, consists in admitting the steam at one end of the coil allowing it to ass progressively through the whole, driving the condensed water, which it will do, though imperfectly, before it." -Commissioner, 1865

"Turbine is, in mechanics, a term formerly confined to horizontal water wheels, the revolution of which is due to the pressure derived from falling water, but now applied generally to any wheel driven by water escaping through small orifices subject to such pressure. The turbine was invented by Fourneyron in 1823, and the first one was made in 1827. Air and steam turbines are also in use, air and steam being used instead of water to drive the impulse wheel."—(Charles Leonard-Stuart, 1911)
