    Desalination of seawater Desalination of seawater Presentation Transcript

    • Desalination of Seawater
      By: Dan Gauvreau
      John Morrison
      Matt Owens
    • 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.
    • 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.
    • Brainstorming Ideas
      Panel Cooker
      Parabolic Cooker
      Box Cooker
      Panel
      Parabolic
      Box
    • 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.

    • 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.
    • 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.
    • 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.
