  • Fossil fuels are not sustainable
  • Fossil fuels are not sustainable• Dwindling petroleum reserves
  • Fossil fuels are not sustainable• Dwindling petroleum reserves• CO2-caused global climate change
  • Fossil fuels are not sustainable• Dwindling petroleum reserves• CO2-caused global climate changeSustainable alternatives to fossil fuel are needed
  • Biofuels as a sustainablealternative to fossil fuel
  • Biofuels as a sustainable alternative to fossil fuel• Carbon neutral
  • Biofuels as a sustainable alternative to fossil fuel• Carbon neutral• Renewable
  • Biofuels as a sustainable alternative to fossil fuel• Carbon neutral• Renewable• Cheaper than fossil fuel
  • Types of biofuel• Traditional food-crop based -corn -sugar cane -soybean
  • Types of biofuel• Non-food biomass based -oil palm -switch grass -algae
  • Algae is a promising new biofuelThe Algae Projecthttp://greengineers.wikispaces.com/file/view/algae_smiley.jpg/115440023/algae_smiley.jpg

  • How is algae traditionally grown?Can algae be grown in an enclosed artificiallight system cost-effectively and morequickly than traditional methods?
  • What could make our enclosed artificial light system more efficient?
  • What could make our enclosed artificial light system more efficient?• Cheap, clean hydro-electricity
  • What could make our enclosed artificial light system more efficient?• Cheap, clean hydro-electricity• 24/7/365 growing period
  • What could make our enclosed artificial light system more efficient?• Cheap, clean hydro-electricity• 24/7/365 growing period• Efficient (9W usage) optimum- wavelength LEDs
  • Proposed Design • Mirror-lined box distributes light evenly
  • Proposed Design • Mirror-lined box distributes light evenly • CO2 promotes rapid growth
  • Proposed Design • Young, light- sensitive algae begin in top CO2 enriched tank
  • Proposed Design • Young, light- sensitive algae begin in top CO2 enriched tank • More mature algae are transferred to bottom light- intensive tank
