  7. 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.
  8. 8. The Steam Engine <ul><li>It is called the Watt Steam Engine is also known as the Boulton and Watt steam engine. </li></ul><ul><li>It was the first type of steam engine to make use of steam at a pressure just above atmospheric to drive the piston helped by a partial vacuum. </li></ul><ul><li>Improving on the design of the 1712 Newcomen engine the Watt steam engine </li></ul><ul><li>It quickly developed from 1763 to 1775, was the next great step in the development of the steam engine. </li></ul><ul><li>Offering a dramatic increase in the new design replaced Newcomen engines in areas where coal was expensive, and then went on to be used in the place of most natural power sources such as wind and water. </li></ul>

  10. 10. Steam Engines: 3 things about <ul><li>A steam engine is an engine which operates by using steam from hot water. They were created circa 1776. It's creation is attributed to James Watt, but he didn't invent it. I will be talking about him later. </li></ul><ul><li>  </li></ul>
  11. 11. Steam Engines: 3 things about <ul><li>Stream engines succeeded horses, windmills and watermills to operate machines in factories. They were also used for mines to move pumps. Later smaller engines were built that could move steam trains and boats. </li></ul><ul><li>  </li></ul>
  12. 12. Steam Engines: 3 things about <ul><li>The steam that it operates with is made in a boiler, which heats water so that the particles move further apart and float more, making it a gas. To boil it, fuels are used, like coal, wood or oil. The steam coming out of the boiler puts the force on a piston or turbine. The movements on the piston or turbines power the engine, so that the wheels are turned. </li></ul><ul><li>  </li></ul>
  13. 13. James Watt: Two things about <ul><li>James Watt (January 19, 1736 - August 19, 1819) was a Scottish engineer and mathematician.  He modified the first steam engine to improve it. He is falsly attributed as the inventor of the steam engine, but that is not true. His most famous work is in developing the modern form of the steam engine. </li></ul><ul><li>  </li></ul>
  14. 14. James Watt: Two things about <ul><li>His father was a shipwright, ship owner and the town's chief baillie, while his mother came from a well educated family. He was home educated most of the time, but he went to real school as well. He had an aptitude for maths and was also a mathmatician. The electrical measurement watt is named after him. </li></ul><ul><li>  </li></ul>

  16. 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. 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.
  18. 18. The steam engine. <ul><li>The term ‘Watts’ which is used in electricity is named after the famous Scotsman who invented the steam engine, James Watt (1736-1819). </li></ul><ul><li>James Watt didn’t actually invent the steam engine, he only just made the first fully functional and reliable one. </li></ul><ul><li>James Watt was part of a society called the Lunar Society. This was a group of scientists and inventors who had meetings and had a very important part in the industrial revolution in Britain. </li></ul><ul><li>The first actual steam powered locomotive was built by Richard Trevithick in 1804. </li></ul><ul><li>Steam power is still used to help run nuclear power plants! </li></ul>By Guilhem
  19. 19. <ul><li>In 1712 Thomas Newcomen invented the first steam engine. </li></ul><ul><li>The steam engine was developed further by James Watt in 1775. This led to the invention of the steam locomotive. </li></ul><ul><li>A unit power familiar with today’s light bulbs, the Watt, was named after James Watt. </li></ul><ul><li>Newcomen’s steam engine was a cylindrical piston which moved up and down. As it rose it was condensed by a spray of water which allowed air pressure to force the piston downwards. </li></ul><ul><li>A much later development was the steam turbine which still powers ships and generators in power stations today. </li></ul>By Kat

  30. 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. 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 &quot;Heron's&quot;) 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. 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.  
  33. 33. Steam Engines and James Watt They used Coal to create steam, Steam engines were the first engine type to see widespread use, They ­powered all early locomotives, steam boats and factories. James Watt…. James Watt was born in Greenock on 18 January 1736. His father was a prosperous shipwright. Watt initially worked as a maker of mathematical instruments, but soon became interested in steam engines. By Scarlet Hayes
  34. 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. 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.

  37. 37. 2 James watt made steam engines to pump coal from mines like this:
  38. 38. <ul><li>3 James Watt was born in 1736 in Scotland </li></ul><ul><li>4 He invented a condenser to stop the waste of energy in steam engines which made them more efficient </li></ul><ul><li>5 Watt’s steam engines did not use high pressure because the boilers used to explode, so he only ever made ones that were at close to atmospheric pressure </li></ul>
  39. 39. By Will <ul><li>James Watt’s early work: </li></ul><ul><li>In 1776, the first engines were installed and working in commercial enterprises. These first engines were used to power pumps and produced only reciprocating motion to move the pump rods at the bottom of the shaft. The design was commercially successful, and for the next five years Watt was very busy installing more engines, mostly in Cornwall for pumping water out of mines. </li></ul>
  40. 40. By Will <ul><li>Early Steam engine: </li></ul><ul><li>Before 1780 there was no good method for making copies of letters or drawings. The only method sometimes used was a mechanical one using linked multiple pens. Watt at first experimented with improving this method, but soon gave up on this approach because it was so cumbersome. He instead decided to try to physically transfer some ink from the original to another sheet of paper which was thin enough for the ink to go through to the other side, thus reproducing the writing exactly. </li></ul>
