7. James Watt James Watt was born in 19 January 1736 and died in 1819 at the age of 83. He was a Scottish inventor and mechanical engineer, who made great improvements to the steam engine. James Watt started of as an instrument maker at the Glasgow University. Watt soon became interested in steam engines and joined another scientist named Mathew Boulton. He realised that current designs at that time wasted a great deal of energy by repeatedly cooling and re-heating the cylinder Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines.

16. Basically, a steam engine is able to harness the energy of steam to move machinery. It is a fairly clean source of energy. Steam engines were used to great effect to run locomotives and steamships. The steam engine was central to the industrial revolution. Only through providing a convenient source of energy could major forms of transportation grow and prosper. Steam engines are still used today to help run nuclear power plants. The Watt - a unit of power familiar today when dealing with light bulbs - was named after James Watt.
17. James Watt was born in Greenock on the 18 th Of January 1736. His father was a prosperous shipwright. Watt initially worked as a maker of mathematical instruments, but soon became interested in steam engines. Watt’s partner and backer was the inventor John Roebuck. In 1775, Roebuck’s interest was taken over by Matthew Boulton who owned an engineering works in Birmingham. Together he and Watt began to manufacture steam engines. Boulton and Watt became the most important engineering firm in the country, meeting considerable demand. Initially this came from Cornish mine owners, but extended to paper, flour, cotton and iron mills, as well as distilleries, canals and waterworks. In 1785, Watt and Boulton were elected fellows of the Royal Society. By 1790, Watt was a wealthy man and in 1800 he retired and devoted himself entirely to research work. He patented several other important inventions including the rotary engine, the double-action engine and the steam indicator, which records the steam pressure inside the engine. Watt died on the 19 th Of August 1819. A unit of measurement of electrical and mechanical power - the watt – is named in his honour.
23. 1. The Watt was named after James Watt. 2. James Watt came up with the term 'horsepower' as a way to help explain how much work his steam engines could do for a potential buyer. 3. Steam engines are still used today to help run nuclear power plants and are also used for tourists on the Frestiniog railway in Porthmadog! 4. Thomas Savery in 1679 was the first person who invented the steam engine for work in mines. 5. The Rocket – the first steam train travelled at an average 12 mph but could reach 25!
30. Steam Engine Facts. 1. The idea of using boiling water to produce mechanical motion has a long history, going back about 2,000 years. Early devices were not practical power producers, but more advanced designs producing usable power have become major source of mechanical power over the last 300 years. 2. In general usage, the term 'steam engine' can refer to integrated steam plants such as railway steam locomotors and portable engines, or may refer to the machinery alone, as in the beam engine and stationary steam engine. Specialized devices such as steam hammers and steam pile drivers are dependent on steam supplied from a separate boiler. 3. The steam engine was a critical component of the Industrial Revolution, providing the power source to propel modern mass-production manufacturing methods. Modern steam turbines generate about 90% of the electric power in the United States using a variety of heat sources.
31. 4. The history of the steam engine stretches back as far as the 1st century AD; the first recorded rudimentary steam engine. Over a millennium after Hero's (or "Heron's") experiments, a number of steam-powered devices were experimented with or proposed, but it was not until 1712 that a commercially successful steam engine was finally developed. 5. During the industrial revolution, steam engines became the dominant source of power and remained so into the early decades of the 20th century. James Watt Facts. 1. James Watt, (19 January 1736 – 25 August 1819) was a Scottish inventor and mechanical engineer whose improvements to the new steam engine were fundamental to the changes brought by the Industrial Revolution in both the united Kingdom and the world. 2. While working as an instrument maker at the University of Glasgow, Watt became interested in the technology of steam engines. He realized that contemporary engine designs wasted a great deal of energy by repeatedly cooling and re-heating the cylinder. Watt introduced a design enhancement, the separate condenser, which avoided this waste of energy and radically improved the power, efficiency, and cost-effectiveness of steam engines. He developed the concept of horsepower. The SI unit of power, the watt, was named after him.
32. 3. Watt attempted to commercialize his invention, but experienced great financial difficulties until in 1775 he entered a partnership with Matthew Boulton. The new firm of Boulton and Watt was eventually highly successful and Watt became a wealthy man. In retirement, Watt continued to develop new inventions though none were as significant as his steam engine work. He died in 1819 at the age of 83. Watt has been described as one of the most influential figures in human history. 4 . James Watt was born on 19 January 1736 in Greenock, Renfrewshire, a seaport on the Firth of Clyde. His father was a shipwright, ship owner and contractor, and served as the town's chief Baillie, while his mother, Agnes Muirhead, came from a distinguished family and was well educated. Both were Presbyterians and strong Covenanters. Watt's grandfather, Thomas Watt, was a mathematics teacher and Baillie to the Baron of Cartsburn. 5 . Watt did not attend school regularly; initially he was mostly schooled at home by his mother but later he attended Greenock grammar school. He exhibited great manual dexterity, engineering skills and an aptitude for mathematics, while Latin and Greek failed to interest him. When he was eighteen, his mother died and his father's health began to fail.

34. The model Newcomen engine upon which Watt experimented. James Watt , was given the job in 1763 of repairing a model Newcomen engine for the University of Glasgow , and noted how inefficient it was. James watt learned the trade of a mathematical-instrument maker. James watt had a partner for the manufacture of his steam engine first John roebuck and then Mathew Boulton. By Tommy.
35. In 1755 Watt was granted a patent for his steam engine. In 1781 Watt produced a rotary motion steam engine. Watt became a member of the lunar society of Birmingham. Watt died on the 25 of august 1819. By Tommy.
