Problem Statement Clean drinkable water, the main source of life, is becoming a scarce resource. Currently, 50% of communities in the developing world are exposed to polluted water sources. Coastal communities have an abundant source of water in the ocean. However, this great source is not commonly utilized for the production clean, consumable water.

Project Description Low cost, easy to reproduce device that uses solar energy to desalinate and purify water using the ocean as the primary source. Target Market: Coastal communities in Peru.
