  • That is amazing tour of history of wind mill. Wind energy is one of good and clean energy source which is largely used, adapted by the various countries for power generation. http://www.bharatbook.com/market-research-report/Wind-Power.html

History of Wind Power

  1. 1. The History <br />Wind Power<br />of<br />
  2. 2. Wind energy conversion is a spellbinding field to study, if only because its past has been so checkered and its exact future is so vague. <br />
  3. 3. But unlike many of these other industries, wind energy has been around for thousands of years and it's a technology that has been reinvented many times.<br />
  4. 4. Have you ever wondered…<br />
  5. 5. WHERE and WHEN did Wind Energy start?<br />
  6. 6.
  7. 7. LET’S GO ON A QUICK JOURNEY<br />
  8. 8. HISTORY<br />OF<br />WIND POWER<br />
  9. 9. 500 B.C.<br />
  10. 10. 500 B.C.<br />The development of sail boats led directly to the development of the first recorded wind powered device in Persia (the Middle East)…<br />
  11. 11. 500 B.C.<br />Sails were used to drive a mill stone for the grinding of grain. These were seen first in Persia, 500 BC. <br />
  12. 12. 500 B.C.<br /> Some versions were also used to pump water for drinking water and for simple irrigation of agricultural land.<br />
  13. 13. 1000 A.D.<br />
  14. 14. 1000 A.D.<br />As sails developed, wind powered devices became even more powerful. <br />
  15. 15. 1000 A.D.<br />The device on the left was very common around this time.<br />
  16. 16. 1000 A.D.<br />In Cyprus and Greece, similar machines can be seen, even today.<br />
  17. 17. 1000 A.D.<br />They are still used to pump water for agricultural use.<br />
  18. 18. 1300 - 1850 A.D.<br />
  19. 19. 1300 – 1850 A.D.<br />This type of windmill design became familiar in Europe between 1300 and 1850 AD. <br />
  20. 20. 1300 – 1850 A.D.<br />The windmill design is much more like the traditional windmills we see even today.<br />
  21. 21. 1300 – 1850 A.D.<br />It was designed particularly for the large scale milling of grain.<br />
  22. 22. 19th Century<br />
  23. 23. 19th Century<br />In the USA wind powered devices like the one shown in the illustration were developed to pump water.<br />
  24. 24. 19th Century<br />These were especially functional in bone-dry areas where deep wells were essential to find drinking water<br />
  25. 25. 19th Century<br />In the 1800s, the Halladay windmill was very trendy with thousands made.<br />
  26. 26. 19th Century<br />This basic design was reliable and was used even up to the 1940s.<br />
  27. 27. 19th Century<br />A large version of this design had rotors (propellers) of 18 meters in length. <br />
  28. 28. 20th Century (USA)<br />
  29. 29. 20th Century (USA)<br />First Use of Wind for Large-Scale Generation of Electricity<br />
  30. 30. 20th Century (USA)<br />With the development of electrical power, scientists and technologists developed ways of producing electricity through the use of wind generators <br />(also known as turbines).<br />
  31. 31. 20th Century (USA)<br />In the 1930s one of the largest experimental machines, called the Palmer-Putman machine was first used.<br />
  32. 32. 20th Century (USA)<br />This was capable of producing 1.25 megawatts of electricity.<br />
  33. 33. 20th Century (USA)<br />However, due to the materials available at the time, its effectiveness was reduced to a great extent and made the machine hard to maintain. <br />
  34. 34. 20th Century (USA)<br />It had 50 meter rotors which were large compared to other designs.<br />
  35. 35. 20th Century (Denmark)<br />
  36. 36. 20th Century (Denmark)<br />After the Second World War the hunt for efficient wind power generators (turbines) restarted.<br />
  37. 37. 20th Century (Denmark)<br />In Denmark the “Gedser Wind Turbine” was created and operated until the mid 1960s. This was 200 Kilowatt machine.<br />
  38. 38. 20th Century (Denmark)<br />The rotors had a set pitch (angle) to catch the wind more efficiently. <br />
  39. 39. 20th Century (Denmark)<br />The main body of the device was built in a similar way to that of the body of an airplane.<br />
  40. 40. 20th Century (Denmark)<br />Airplane technology was applied successfully to the device making it the most efficient device of its time.<br />
  41. 41. 20th Century (Denmark)<br />However, progress in the generation of electricity through wind power was sluggish in the 1950s and 1960s. <br />
  42. 42. 20th Century (Denmark)<br />This was because fossil fuels were relatively cheap.<br />
  43. 43. European Development<br />
  44. 44. European Development<br />Throughout the 1960s, Professor Ulrich Hutter, a German technologist, designed a number of wind generators that used modern materials such as fiberglass and plastic.<br />
  45. 45. European Development<br />The lighter materials meant that the device could operate in lighter winds, generating electricity. <br />
  46. 46. European Development<br />Slowly but surely, wind powered turbines were beginning to look economic to build and maintain.<br />
  47. 47. Due mainly to the fast rise in oil prices throughout the late 1970s and 1980s,<br />
  48. 48. AND<br />
  49. 49. the fact that using fossil fuels to produce electricity causes pollution,<br />
  50. 50. which can damage the environment and cause global warming,<br />
  51. 51. The development of wind generators (turbines)…<br />
  52. 52. ACCELERATED!!!<br />
  53. 53. THE RISE OF MODERN<br />WIND TURBINES<br />
  54. 54. Modern wind turbine generators are robust, sophisticated high-tech machines designed to convert the power of the wind into electricity.<br />
  55. 55. They generally consist of a rotor with three blades.<br />
  56. 56. A nacelle, which typically contains a gear box, generator, brake, yaw motor, and yaw drive.<br />
  57. 57. And an anemometer for measuring wind speed.<br />
  58. 58. This is how it looks like …<br />
