| | Steam engine - Wikipedia, the free encyclopedia |
 | | Steam engines were used as the prime mover in pumps, locomotives, steam ships and steam tractors, and were essential to the Industrial Revolution. |
 | | Steam turbines, technically a type of steam engine, are still widely used for generating electricity, but older types have been almost entirely replaced by internal combustion engines and electric motors. |
 | | One of the advantages of the steam engine is that any heat source can be used to raise steam in the boiler; but the most common is a fire fueled by wood, coal or oil or the utilisation of the heat energy generated in a nuclear reactor. |
