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
Rim-driven thruster Rim-driven thruster Rim-Driven Thruster is a novel type of propulsion unit which was presented at the Shipbuilding, Machinery & Marine Technology 2010 trade fair (SMM) by the companies "Voith" and "Van der Velden". The Rim-driven thruster is a marine propeller which does not need a hub for transmission of the driving torque. Conventional propellers need a shaft line which is driven by a turbine, a diesel engine or an electric motor. The more recent podded drives consist of a conventional propeller which is arranged together with a conventional electric motor into an azimuthable gondola under water. The blades of the
