Our Engr215 Introduction to Design class from Humboldt State University was divided into seven teams, each consisting of four members. Each team was given one of three assignments:
- Create a smaller version of the UNS to be marketed in the US in order to fund FBP's efforts abroad.
- Find a way to make a UNS out of cheaper, lighter and more sustainable materials for the countries of West Africa.
- Find a way to make molds out of recycled plastic bags for the working parts of the UNS using extremely limited resources in Haiti.
Our team worked on the first of these assignments by redesigning the UNS to be marketable in the United States.

The Earth's water moves constantly through a cycle of evaporation and transpiration (evapotranspiration), precipitation, and runoff, usually reaching the sea. Over land, evaporation and transpiration contribute to the precipitation over land - thus deforestation and other changes to land can have wide and long-lasting effects through their impact on the water cycle. Some observers estimate that by 2025 more than half of the world population will be vulnerable to a lack of water. Appropriate water supply and water purification technologies can help. |
