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 ...

Used early on in electrical generation and to power ships, turbines were bladed wheels that created rotary motion when high pressure steam was passed through them. The efficiency of large steam turbines was considerably better than the best compound engines, while also being much simpler, more reliable, smaller and lighter all at the same time ...

[1] [2] However, Vitruvius was the first to describe this appliance in his De architectura (c. 30-20 BC). [3] The aeolipile is considered to be the first recorded steam engine or reaction steam turbine, but it is neither a practical source of power nor a direct predecessor of the type of steam engine invented during the Industrial Revolution. [4]
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.
Steam turbines, dairy machinery, and the de Laval nozzle for rocket engines Signature Karl Gustaf Patrik de Laval ( Swedish pronunciation: [ˈɡɵ̂sːtav dɛ laˈvalː] ⓘ ; 9 May 1845 – 2 February 1913) was a Swedish engineer and inventor who made important contributions to the design of steam turbines and centrifugal separation machinery ...
