How James Watt Affected Our Nation's Economic GrowthJames Watt made many contributions to this country during the Industrial Revolution. He made many improvements to the Newcome steam engine, coined the term horsepower, and designed the Sun and Planet wheel. He dedicated most of his life to making other people's lives easier and allowing them to 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 and was therefore economically inefficient. The reasons for this inefficiency were 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 walking around Glasgow Green he had an idea that would revolutionize the steam engine. This idea was “that to make the best use of steam, it was necessary that, firstly, the cylinder should always remain as hot as the steam entering it; secondly, that when the steam condensed, the water from which it was composed and 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 be opened between a cylinder containing steam and another container emptied of air and other fluids, the steam, as an elastic fluid, would immediately rush into the empty container, and continue to do so until it has established an equilibrium. If this container were kept dry and cool by injection, or otherwise, more steam would continue to enter until everything was condensed. He solved the problem of water and air coming out of the spent container by adding a pump to extract the air and water. This was 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 an economical and useful source of power that remained exactly the same without modification for over a hundred years. Watt charged his customers a price for the use of his steam engines. To justify himself, he compared his machine to a horse. Watt calculated that a horse exerted a pulling force of 180 pounds. Therefore, when he made a machine, he described its power in relation to that of a horse..
