Solar Tower

  1. 1. The Australian Solar Tower Project By Jayan Hewaparakrama duPont Manual High School March 23, 2009
  2. 2. <ul><li>Currently much of Earths non-renewable energy is being depleted by human consumption </li></ul><ul><ul><li>Petroleum </li></ul></ul><ul><ul><li>Natural Gas </li></ul></ul><ul><ul><li>Coal </li></ul></ul><ul><ul><li>Propane Gas </li></ul></ul><ul><ul><li>Nuclear Energy </li></ul></ul>Energy Crises
  3. 3. <ul><li>Renewable energy is basically energy that we can recycle and reuse </li></ul><ul><ul><li>Wind energy </li></ul></ul><ul><ul><li>Geothermal energy </li></ul></ul><ul><ul><li>Solar energy </li></ul></ul><ul><ul><li>Hydro energy </li></ul></ul>Renewable Energy
  4. 4. Solar Energy <ul><li>Energy (radiant light and heat) produced by the sun </li></ul><ul><ul><li>Captured by humans </li></ul></ul><ul><ul><ul><li>Solar cells </li></ul></ul></ul><ul><ul><ul><li>Solar heaters </li></ul></ul></ul><ul><ul><ul><li>parabolic dish </li></ul></ul></ul><ul><ul><ul><li>Solar towers </li></ul></ul></ul>
  5. 5. Overview of Solar Tower <ul><li>The Australian solar tower is still a proposed type of renewable energy. </li></ul><ul><li>Dimensions </li></ul><ul><ul><li>Base is 3.5 miles in diameter (30 million square yards) </li></ul></ul><ul><ul><li>The tower is 1000 meters high </li></ul></ul><ul><li>The solar tower contains </li></ul><ul><ul><li>collector area (glass/polycarbonate/plastic film)- is able to take in heat from the sun and heat the air molecules under the collector area. </li></ul></ul><ul><ul><li>The tower is made from concrete </li></ul></ul><ul><ul><li>As the heated air molecules tries to escape through the top of the tower, 32 wind turbines turn generating electricity . </li></ul></ul>
  6. 6. <ul><ul><li>A single 200 Mega Watt Solar Tower </li></ul></ul><ul><ul><ul><li>Provide enough electricity to power around 200,000 households. </li></ul></ul></ul><ul><ul><ul><ul><li>the number of homes in a city the size of Geelong (major suburb of metropolitan Victoria, Australia). </li></ul></ul></ul></ul><ul><li>The energy output will represent an annual saving of more than 900,000 tons of greenhouse gases from entering the environment. </li></ul>Overview of Solar Tower…..

  8. 8. Solar Tower Technology <ul><li>The sun's radiation is used to heat a large body of air under an expansive collector zone, </li></ul><ul><ul><li>According to the laws of physics, hot air rises </li></ul></ul><ul><ul><li>hot wind moves through large turbines to generate electricity. </li></ul></ul><ul><li>A Solar Tower power station will create the conditions to cause hot wind to flow continuously through 32 x 6.25MW pressure staged turbines to generate electricity. </li></ul><ul><li>During the night, the heated ground heats the air molecules </li></ul><ul><ul><li>1000 meters above the surface is much cooler, so air molecules continuously travel. </li></ul></ul>
  9. 9. How the Solar Tower Functions
  10. 10. Location of Solar Tower <ul><li>Australia is an excellent location for a Solar Tower </li></ul><ul><ul><li>vast areas of high solar radiation levels </li></ul></ul><ul><ul><li>geological stable and low land costs </li></ul></ul>Progress <ul><li>Project optimization (completed) </li></ul><ul><li>Pre-Feasibility Commercialization (completed) </li></ul><ul><li>Final Feasibility (underway) </li></ul><ul><li>Final Design and Construction </li></ul><ul><li>Construction </li></ul><ul><li>Commercial Operation </li></ul>
  11. 11. Pros/cons <ul><li>Renewable type of energy </li></ul><ul><li>Reduces Global Warming </li></ul><ul><li>Cost is too high </li></ul><ul><li>Needs a large area </li></ul><ul><li>Lot of maintenance work needs to be done in order for it to function properly </li></ul>
