Steam turbine steam jacks. In 1672 an impulse steam turbine driven car was designed by Ferdinand Verbiest. A more modern version of this car was produced some time in the late 18th century by an unknown German mechanic. In 1775 at Soho James Watt designed a reaction turbine that was put to work there. In 1827 the Frenchmen Real and Pichon patented and constructed a compound impulse turbine. The modern steam turbine was invented in 1884 by Sir Charles Parsons, whose first model was connected to a dynamo that generated 7.5 kW (10 hp) of electricity. The invention of Parsons' steam turbine
George Rennie (engineer) Croydon Railway. Many orders for foreign governments were executed, and the firm were employed by the Admiralty in making engines for the Royal Navy. He was much interested in the screw-propeller, and his firm built the engines for , the world's first propeller-driven steamship. Subsequently, in 1840, the firm built for the Admiralty the "Dwarf", the first vessel in the British navy propelled by a screw. Roe (1916) discusses Rennie's contributions to the development of the planer. In 1822 he was elected Fellow of the Royal Society, and contributed papers to the Transactions in 1829 on the friction of metals
