How James Watt Influenced Our Nation's Economic GrowthJames Watt made many contributions to this country during the Industrial Revolution. He made numerous improvements to the Newcome steam engine, invented the term horse power, and designed the Sun and Planet wheel. He has contributed much of his life to making the lives of others easier and helping them prosper and grow. In 1763 John Anderson asked Watt to repair one of his steam engines which was an early version of a Newcome steam engine. This engine wasted a lot of time and fuel, so it was economically inefficient. The reason for the inefficiency was that the cylinder had to be heated when steam was admitted and then slowly cooled again to condense the steam. This process wasted a lot of time, energy and steam. While wandering around Glasgow Green an idea came to him that would revolutionize the steam engine. This idea was "that to make best use of the steam it was necessary that firstly the cylinder always remain as hot as the steam entering it; secondly that when the steam condensed, the water of which it is composed, and the the injection itself, should be cooled to 100 degrees, or less, where possible." This method did not work at first, but in 1765 he discovered "that if a communication were opened between a cylinder containing steam and another container, which was exhausted of air and other fluids, the steam, as an elastic fluid, would immediately pour into the container empty, and continue to do so until an equilibrium is established 'water and air that escaped from the spent vessel by adding a pump to extract both air and water This is Watt's great contribution to the Newcome steam engine which would now run faster, cleaner, safer and more economically efficient.This made the steam engine a useful source of economical energy that for over a hundred years remained exactly the same without alteration. Watt charged his customers for using his steam engines. To justify this he compared his car to a horse. Watt calculated that a horse exerted a force of 180 pounds, so when he built a machine, he described its power in relation to a horse.
