Transcript

  • 1. Desalination of Seawater
    By: Dan Gauvreau
    John Morrison
    Matt Owens
  • 2. Design Brief
    Develop a process to desalinate sea-water using 75% recycled materials.
    Create a reflective structure to focus sunlight on a water containment device in order to separate salt from the water through evaporation.
  • 3. Research
    Average Temperature-26 Celsius.
    Over 20 days without rain in July and August on average.
    Most of the water in Samoa is polluted.
    Population is located on the coast mostly.
    People need 2 liters of water a day to be healthy.
  • 4. Brainstorming Ideas
    Panel Cooker
    Parabolic Cooker
    Box Cooker
    Panel
    Parabolic
    Box
  • 5. Parabolic Cooker
    Would be built out of an umbrella covered in aluminum foil with a 2 liter bottle attached to the shaft.
    Needs to be adjusted to face the sun every ten minutes.
    Would be fairly simple to make.

  • 6. Panel Cooker
    Consists of panels of cardboard covered in aluminum foil.
    Does not need to be adjusted to
    face the sun often.
    Would take more time to make
    than the box or the parabolic.
  • 7. Box Cooker
    Built out of 2 cardboard boxes and a lid covered in aluminum foil.
    Does not need to be adjusted to face the sun often.
    Would not take long to make
    and is very simple.
  • 8. Containment Device
    After the water from the 2 liter bottle is boiled is would condense on plastic wrap above it.
    It would then fall into a aluminum tin that would be next to the bottle.
