A steam engine is a heat engine that performs mechanical work using steam as its working fluid. The steam engine uses the force produced by steam pressure to push a piston back and forth inside a cylinder. This pushing force can be transformed by a connecting rod and crank into rotational force for work.

When liquid water becomes steam, it increases in volume by 1,700 times at standard temperature and pressure; this change in volume can be converted into mechanical work by steam engines such as reciprocating piston type engines and steam turbines, which are a sub-group of steam engines. Piston type steam engines played a central role in the ...
1790 (): Nathan Read invented the tubular boiler and improved cylinder, devising the high-pressure steam engine. 1791 (): Edward Bull makes a seemingly obvious design change by inverting the steam engine directly above the mine pumps, eliminating the large beam used since Newcomen's designs. About 10 of his engines are built in Cornwall.
