The steam turbine was developed by Sir Charles Parsons in 1884. His first model was connected to a dynamo that generated 7.5 kW (10 hp) of electricity. The invention of Parson's steam turbine made cheap and plentiful electricity possible and revolutionized marine transport and naval warfare. By the time of Parson's death, his turbine had been adopted for all major world power stations. Unlike earlier steam engines, the turbine produced rotary power rather than reciprocating power which required a crank and heavy flywheel. The large number of stages of the turbine allowed for high efficiency and reduced size by 90%. The turbine's first application was in shipping followed by electric generation in 1903.
