  9. 9. A plan for India
  10. 10. Complete protecting system for earth</li></li></ul><li>Why solar energy??<br /><ul><li>India is fastest growing economy with home of 1.5 billion people .
  11. 11. Largely depended on conventional sources of energy & imported oil .
  12. 12. Sun- The only source of energy to the earth.
  13. 13. Geographical conditions of India.</li></li></ul><li>What is wireless energy transmission?? <br /><ul><li>Possible – by magnetic field or electromagnetic field.
  14. 14. One form of energy is converted into another transmissible form and again into usable form.
  15. 15. Our interest lies in transmission via LASER.</li></li></ul><li>Why to use wireless energy transmission via LASER for solar energy??<br />Solar power intensity is just- 137mW/cm2<br /><ul><li>Long distance transmission possible.
  16. 16. Solar energy- Not a concentrated source of energy.
  17. 17. Losses due to scattering of light.
  18. 18. Presently only 3% of solar energy is being utilized.
  19. 19. To increase efficiency of power station.
  20. 20. Reduce the size of power plants.
  21. 21. Increase power generation capacity of power plant.</li></li></ul><li>A quick view to intelligent power system with the help of WET!<br />
  22. 22. How to build smart power system with the help of WET??<br /><ul><li>Huge solar tower to be set up to set up at geostationary orbit.
  23. 23. Structure of solar tower- Huge tower attach with directly pumped solar LASER diodes , mirrors , lens ,controlling system for beam.
  24. 24. Receiving power stations all over India.
  25. 25. Power station – array of high efficiency high power solar cell.
  26. 26. Controlling station.
  27. 27. So energy conversion –solar energy to concentrated light energy – electrical energy. </li></li></ul><li>Directly pumped solar LASER<br /><ul><li>P-N junction diode operating in forward direction
  28. 28. Uses electron hole pair as exciting material.
  29. 29. Directly exited by solar energy.
  30. 30. GaAs LASER best material for Lasing action.
  31. 31. High efficiency about 50% to 75%.
  32. 32. Inherently light weight.
  33. 33. Output wavelength -800 to 900 nm close to peak response wavelength of today's solar cells.
  34. 34. Need of mirror or lens for concentrating light for population inversion. </li></li></ul><li>How the power system will work?<br /><ul><li>The huge solar towers directly convert solar energy into concentrated LASER beam.
  35. 35. LASER beam will be concentrated on receiving power station.
  36. 36. Highly efficient solar cells or rectenna will convert it into electric energy.
  37. 37. This station will supply power to nearby area.
  38. 38. With this technology it is expected 1GW of power can be generated. </li></li></ul><li>How it will increase the efficiency of power plants??<br /><ul><li>More energy will be concentrated on small area.
  39. 39. Receiving energy will lie in useful energy band in spectrum.
  40. 40. High efficiency of LASER diode.
  41. 41. Input to panels will be sunlight+ concentrated beam.
  42. 42. Improve losses due to transmission via wires.
  43. 43. Efficiency of system will be 35% to 40% much more than present plants. </li></li></ul><li>Sunlight + Laser-PV WPT = ~ Power RequirementPhoto-Voltaic (PV) Power Station Receives Both<br />Total Power at PV Receiver<br />PV Power from WPT-Light<br />PV Power from Sunlight<br />1.2<br />1.0<br />0.8<br />+<br />=<br />Normalized Power / Area<br />0.6<br />0.4<br />0.2<br />0.0<br />6<br />12<br />18<br />24/0<br />6<br />12<br />18<br />24<br />0<br />6<br />12<br />18<br />24/0<br />Time (Hours)<br />Time (Hours)<br />Time (Hours)<br />Electrical Power Demand<br />Normalized Output from SPS<br />(Non-Tracking Arrays)<br />Normalized Output from Sun<br />Normalized Total Output<br />Typical Electricity Demand<br />
  44. 44. A plan for India <br />
  45. 45. A plan for India <br /><ul><li>Can be used as mobile power station
  46. 46. A controlling station for satellite on the earth.
  47. 47. Receiving power stations in each state.
  48. 48. Specially remote areas like lakhshwadeep Andmaan Nicobar islands, North Eastern region military areas,Jammu Kashmir.
  49. 49. Power should be supplied to these station periodically.
  50. 50. If any region suffers from power shortage beam should be directed to that region.
  51. 51. Power can be supplied to neighboring countries. </li></li></ul><li>Complete protecting system for earth<br />Celestial body<br />
