Detailed explanation-1: -Did James Watt invent the steam engine? James Watt did not invent the steam engine. He did, however, improve the engine apparatus. In 1764 Watt observed a flaw in the Newcomen steam engine: it wasted a lot of steam.
Detailed explanation-2: -While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. He realised that contemporary engine designs wasted a great deal of energy by repeatedly cooling and reheating the cylinder.
Detailed explanation-3: -James Watt (1736-1819) was a prolific inventor, surveyor, instrument maker and engineer. His engines dramatically increased the power that could be generated through steam.
Detailed explanation-4: -In 1698 Thomas Savery patented a pump with hand-operated valves to raise water from mines by suction produced by condensing steam. In about 1712 another Englishman, Thomas Newcomen, developed a more efficient steam engine with a piston separating the condensing steam from the water.
