Desalination of seawater

  1. 1. Desalination of Seawater<br />By: Dan Gauvreau<br />John Morrison<br />Matt Owens<br />
  2. 2. Design Brief<br />Develop a process to desalinate sea-water using 75% recycled materials.<br />Create a reflective structure to focus sunlight on a water containment device in order to separate salt from the water through evaporation.<br />
  3. 3. Research<br />Average Temperature-26 Celsius.<br />Over 20 days without rain in July and August on average.<br />Most of the water in Samoa is polluted.<br />Population is located on the coast mostly.<br />People need 2 liters of water a day to be healthy.<br />
  4. 4. Brainstorming Ideas<br />Panel Cooker<br />Parabolic Cooker<br />Box Cooker<br />Panel<br />Parabolic<br />Box<br />
  5. 5. Parabolic Cooker<br />Would be built out of an umbrella covered in aluminum foil with a 2 liter bottle attached to the shaft.<br />Needs to be adjusted to face the sun every ten minutes.<br />Would be fairly simple to make.<br />http://www.google.com/imgres?imgurl=http://upload.wikimedia.org/wikipedia/commons/4/4c/SOLAR_COOKER_001.JPG&imgrefurl<br />
  6. 6. Panel Cooker<br />Consists of panels of cardboard covered in aluminum foil.<br />Does not need to be adjusted to<br /> face the sun often.<br />Would take more time to make<br /> than the box or the parabolic.<br />
  7. 7. Box Cooker<br />Built out of 2 cardboard boxes and a lid covered in aluminum foil.<br />Does not need to be adjusted to face the sun often.<br />Would not take long to make<br /> and is very simple.<br />
  8. 8. Containment Device<br />After the water from the 2 liter bottle is boiled is would condense on plastic wrap above it.<br />It would then fall into a aluminum tin that would be next to the bottle.<br />
