    • The Transportation Solution of the Future SPA Kahului’s Transportation Future
    • 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
    •  
    • Community
      • Kahului
      • It is our home; our aina
      • It is also small enough to be a good place to test our system .
      Our Community
    • Why is it important to find alternate and renewable fuel sources for our COMMUNITY?
      • FOSSIL FUELS ARE:
        • Limited, Demand is increasing, Cost is increasing, Creates pollution
      • THE ALTERNATIVE ENERGY WE ARE LOOKING AT ARE:
        • UNLIMITED, FREE, AND IS POLLUTION FREE
    • Problems with Cars
      • Cost
      • Efficiency
      • Safety
    • Why Did We Choose Solar/Wind Powered Golf Carts?
      • First we thought of using biomass as fuel, but the conversion plants did not seem practical.
      • 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.
    • Why Did We Choose Solar/Wind Powered Golf Carts?
      • We also had a golf cart ready for us to convert
      • The solar technology to convert golf carts is available
    • Solutions to Charge
      • Used solar & wind energy to run and power our system
      • Chose solar and wind energy because Maui is usually sunny and has trade winds
      • Free energy resources
      • Creating and storing energy during the day
      • Using Maui Electric Company’s grid
      • “ deposit & withdraw” energy
      Net Metering= "Energy Bank"
    • Photovoltaic cells
      • Changes sunlight to energy
      • -absorbs energy from the sun to semiconductor
      • -then, electrons move around, which is called a current
      • -when metal is put near this current you can pull current or energy out of the PV cell
    • Vertical Wind Turbines
      • Using vertical instead of horizontal to save more space
      • More vertical wind turbines around the stations to create more energy
      • They are also much quieter.
    • Positives of SPA System
      • 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.
      • Convenient locations for charging and eventually Kahului residents will purchase their own.
    • Assorted Sizes
      • Multiple sizes to accommodate all groups.
    •  
    • Actual Outcome of our Project
      • Sunetric sponsored us so we were actually able to create a prototype of the SPA.
      • They are also going to install a PV system on our school, which will make us more eco-friendly and save us money.
    • Actual Outcome of our Project
      • We will also have meters that we can use to run all kinds of solar related science projects….
      • how exciting!
      • We were able to share our SPA solution with the community at our SCC night and our presentation to Mayor Tavares.
      Another Benefit...
