Parsons' steam turbine generator, 1884.

Parsons' steam turbine-generator, 1884.
Parsons' original Steam Turbine generator with spare guide ring and fan 1884. Made by Clarke, Chapman, Parsons & Co. This machine is the forerunner of the turbo-generators that today provide most of the world's electricity. It is the first experimental prototype produced by Charles Parsons, who promoted the turbine as a smaller and more efficient alternative to the steam reciprocating engine. In the turbine, the expanding steam works continuously as it passes through many turbine stages. This gives far higher efficiency than was possible with the steam engine. The turbine combines freedom from vibration with high speed (in this case, 18,000 revolutions per minute) suited to electrical generators. The turbine was also employed in marine propulsion. In 1894 Parsons launched his first turbine-powered boat, the SS Turbinia, which reached previously-unattainable speeds of up to 34 knots.
