The idea was to replace the reciprocating action of the original. James Watt was urged by Boulton to invent some form of rotary motion for his steam engines. So fast, in fact, that by 1776 two engines were installed and fully functional.Д«oulton and Watt Steam Engine Source : Ariadacapo/Wikimedia Commons Boulton spots new opportunities The financial support that Boulton provided allowed for the rapid progress of Watt's engine. The same year Boulton and Watt would form a more official partnership that would last for more than 25 years. James Watt's patent was extended by the British Parliament in 1775.

His partnership with Boulton would provide James with access to some of the best ironworkers in the world. Partly owing to his new partnership with Boulton, James moved to Birmingham in 1774. After eight years of land surveying, James would become jaded with the task. An English manufacturer and engineer Matthew Boulton who was also the manufacturer of the Soho Works in Birmingham took over Roebuck's shares in Watt's patent.

His partner Roebuck would sadly go bankrupt in 1772. This work severely ate his time and his work on his new steam engine was severely set back. The next eight years of his life was consumed marking out routes for canals in Scotland. The following year Watt took out the famousВ patentВ for вЂњA New Invented Method of Lessening theВ ConsumptionВ of Steam and Fuel in Fire Engines.вЂќ This was pursued at the great cost of capital. They were, therefore, unable to produce the components with high enough precision. Ironworkers at the time were more akin to blacksmiths that modern-day machinists. The engine's progress was stalled because of the difficulty in machining the piston and cylinder for his engine. The small cottage where Watt worked on his revolutionary steam engine. Arguably the birthplace of the Industrial Revolution. The cottages shell and a very large part of one of his experiments still exist today. Roebuck lived at Kinneil House, Bo'ness at the time and Watt would work in perfecting the engine in a small adjacent cottage to the house. His prototype was made possible by some loans from Joseph Black. James Watt and John would enter into a partnership together after he had made a small test engine. John was the founder of the Carron Works and it was he that encouraged James to make his own engine. James would later meet the British Physician, chemist, and inventor John Roebuck. This would produce a considerable increase in the availability of energy to perform useful work. This would mean that very little energy was absorbed by the cylinder every time it cycled. James also realized that the engine would need to maintain the temperature of the cylinder at the same temperature as the injected steam by surrounding it with a 'steam jacket.' He realized was to cause the steam to condense in a separate cylinder apart from the piston. Source: Andy Dingley/Wikimedia Commons James hits on an idea Watt's solution would have theВ condensation effected in a chamber distinct from the main cylinder but connected to it. This loss of latent heat was a huge defect with the Newcomen engine in James's opinion. Thus by repeatedly heating and cooling the cylinder, the engine wasted most of its thermal energy rather than converting it intoВ mechanical energy. This energy was wasted because later in the cycle cold water was injected into the cylinder to condense the steam to reduce its pressure. He continued to experiment with it and found that around three-quarters of the thermal energy of the engine were being consumed in heating the engine cylinder on every cycle.

James managed to repair the model but it hardly worked. The science of thermodynamics would not be formalized for at least another 100 years. At this time understanding of the steam engine was in a very primitive state. Watt had noticed that the problem with the Newcomen steam engine was its loss of latent heat. This was to be his first and greatest invention. James's idea was to provide the engine with a separate condenser. Its design had hardly changed in that time. The Newcomen engine had been in use for almost 50 years for pumping water from mines.
