Fll Slide Show Revision 117

  1. 1. The Transportation Solution of the Future SPA Kahului’s Transportation Future
  2. 2. Community: Kahului Transportation: Cars Solution: SPA System—Solar Powered Automobiles (Solar Powered Golf Carts) to replace all fossil fuel dependant cars Charging stations for the SPA system Will Have: -Photovoltaic Cells on roof -Vertical wind turbines
  3. 4. Community <ul><li>Kahului </li></ul><ul><li>It is our home; our aina </li></ul><ul><li>It is also small enough to be a good place to test our system . </li></ul>Our Community
  4. 5. Why is it important to find alternate and renewable fuel sources for our COMMUNITY? <ul><li>FOSSIL FUELS ARE: </li></ul><ul><ul><li>Limited, Demand is increasing, Cost is increasing, Creates pollution </li></ul></ul><ul><li>THE ALTERNATIVE ENERGY WE ARE LOOKING AT ARE: </li></ul><ul><ul><li>UNLIMITED, FREE, AND IS POLLUTION FREE </li></ul></ul>
  5. 6. Problems with Cars <ul><li>Cost </li></ul><ul><li>Efficiency </li></ul><ul><li>Safety </li></ul>
  6. 7. Why Did We Choose Solar/Wind Powered Golf Carts? <ul><li>First we thought of using biomass as fuel, but the conversion plants did not seem practical. </li></ul><ul><li>Then we thought of pedal powered or assisted energy, but the conversion of the available golf cart was mechanically too complex to complete in time. </li></ul>
  7. 8. Why Did We Choose Solar/Wind Powered Golf Carts? <ul><li>We also had a golf cart ready for us to convert </li></ul><ul><li>The solar technology to convert golf carts is available </li></ul>
  8. 9. Solutions to Charge <ul><li>Used solar & wind energy to run and power our system </li></ul><ul><li>Chose solar and wind energy because Maui is usually sunny and has trade winds </li></ul><ul><li>Free energy resources </li></ul>
  9. 10. <ul><li>Creating and storing energy during the day </li></ul><ul><li>Using Maui Electric Company’s grid </li></ul><ul><li>“ deposit & withdraw” energy </li></ul>Net Metering= &quot;Energy Bank&quot;
  10. 11. Photovoltaic cells <ul><li>Changes sunlight to energy </li></ul><ul><li>-absorbs energy from the sun to semiconductor </li></ul><ul><li>-then, electrons move around, which is called a current </li></ul><ul><li>-when metal is put near this current you can pull current or energy out of the PV cell </li></ul>
  11. 12. Vertical Wind Turbines <ul><li>Using vertical instead of horizontal to save more space </li></ul><ul><li>More vertical wind turbines around the stations to create more energy </li></ul><ul><li>They are also much quieter. </li></ul>
  12. 13. Positives of SPA System <ul><li>Equipment is expensive. For instance, a finished SPA would cost from 8 to 10 thousand dollars, BUT it’s cheaper than maintaining a gasoline car. </li></ul><ul><li>Convenient locations for charging and eventually Kahului residents will purchase their own. </li></ul>
  13. 14. Assorted Sizes <ul><li>Multiple sizes to accommodate all groups. </li></ul>
  14. 16. Actual Outcome of our Project <ul><li>Sunetric sponsored us so we were actually able to create a prototype of the SPA. </li></ul><ul><li>They are also going to install a PV system on our school, which will make us more eco-friendly and save us money. </li></ul>
  15. 17. Actual Outcome of our Project <ul><li>We will also have meters that we can use to run all kinds of solar related science projects…. </li></ul><ul><li>how exciting! </li></ul>
  16. 18. <ul><li>We were able to share our SPA solution with the community at our SCC night and our presentation to Mayor Tavares. </li></ul>Another Benefit...
  17. 20. Solar Wind Powered Transportation SPA Systems
