Solar Powered Water Distillation Device
  • Eric Frasch, Mike Santorella, Mikio Yanagisawa,
    Stephen Coffrin

Advisor Professor Mohammed Taslim
2
Problem Statement
  • Over 1 billion people without access to clean
    water worldwide
  • 26.8 in Africa
  • Clean water essential to stop spread of disease
    improve overall health
  • Solar energy untapped resource

3
Project Statement
  • Design low cost, solar powered water distillation
    device for coastal areas of Africa without access
    to clean drinking water

4
Project Goals
  • Solar powered
  • Affordable
  • 2-4 gallons per day
  • Practical
  • Efficient
  • Easy to clean

5
Water Distillation
  • Process that removes impurities contaminants
  • How?
  • Heat water to point of vaporization
  • Water vapor condenses on cooler surfaces
  • Condensate runs off into collection bin

6
Patent Periodical Research Results
  • Beneficial Ideas
  • Troughs
  • Water height lt 2 cm
  • Mirrors
  • Beneficial Information
  • Asymmetrical superior to other designs
  • 30 more efficient

Project
The Water Cone
  • Unit Cost - 479.00
  • Estimated cost 400-600
  • Built supplied by aid organization
  • Not currently in production
  • Very low output

8
Thermal Circuit
  • Energy balance at water, glass, and air inside
  • Spreadsheet program developed
  • Inputs ? Output temperatures
  • Results 2 gallon output requires 1 m2

9
Thermal Circuit Validation

Importance of Solar Power
  • UN Climate Change Conference (Indonesia)
  • Attempting to agree to curb the amount of
    greenhouse gas emissions
  • The Earth's atmosphere is being changed at an
    unprecedented rate by pollutants resulting from
    wasteful fossil fuel use ... These changes
    represent a major threat to international
    security and are already having harmful
    consequences over many parts of the globe.... it
    is imperative to act now.
  • Emphasizes the importance of using renewable
    resources
