The modern steam turbine was invented in 1884 by Charles Parsons, whose first model was connected to a dynamo that generated 7.5 kilowatts (10.1 hp) of electricity. [12] The invention of Parsons' steam turbine made cheap and plentiful electricity possible and revolutionized marine transport and naval warfare. [13] Parsons' design was a reaction ...
During the Industrial Revolution, steam engines started to replace water and wind power, and eventually became the dominant source of power in the late 19th century and remaining so into the early decades of the 20th century, when the more efficient steam turbine and the internal combustion engine resulted in the rapid replacement of the steam ...
1862 (): The steam engine indicator is exhibited at the London Exhibition. Developed for Charles Porter by Charles Richard, the steam engine indicator traces on paper the pressure in the cylinder throughout the cycle, which can be used to spot various problems and to optimize efficiency.
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.
In 1912 Zoelly was awarded an honorary degree from the ETH Zurich, partly thanks to his work in turbine development. Since Zoelly was convinced of the superiority of the steam turbine to the steam piston engine, in 1913 Escher Wyss & Cie. abandoned the production of steam engines and concentrated fully on turbines.
Coupled with a Parsons turbine, the output of a Ljungström turbine can be increased to about 50 MW. Since more modern steam power plants have a significantly higher performance, the Ljungström turbine is generally no longer utilised today. The largest ship ever built, the ULCC supertanker Seawise Giant, was powered by this type of engine. [7]

Curtis' turbine reached a lower efficiency than the Parsons' turbine. It was, however, much smaller and simpler in design, thus making it suitable for simple applications and mobile use (e.g.on steamships). Curtis spoke to various companies about his turbines, but met no interest until he met Edwin W. Rice of General Electric.
