Desalination of SeawaterBy: Dan Gauvreau

John MorrisonMatt Owens

Design BriefDevelop 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.

ResearchAverage 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 IdeasPanel CookerParabolic CookerBox Cooker

Parabolic

Panel

Box

Parabolic CookerWould 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 CookerConsists 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 CookerBuilt 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 DeviceAfter 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.
