Steam Engine

Inventor : Thomas Newcomen

Type : Heat Engine

Invent date : 1712

application : In 1781 James Watt patented a steam engine that produced continuous rotative motion. Watt's ten-horsepower engines enabled a wide range of manufacturing machinery to be powered. The engines could be sited anywhere that water and coal or wood fuel could be obtained. By 1883, engines that could provide 10,000 hp had become feasible. Steam engines could also be applied to vehicles such as traction engines and the railway locomotives. The stationary steam engine was a key component of the Industrial Revolution, allowing factories to locate where water power was unavailable.
