Sunly Sweetwater

The Brazilian semiarid region has too much sun and too little water, part of it highly brackish, what if the sun could make it drinkable?

Long Description

“And the backlands are a fertile valley. It is a vast, unowned orchard.
Then this is all over. The torturous days are back; the suffocating atmosphere; the soil becoming stone; the nudity of flora; and at times when the seasons connect without one break for a rain… the haunting cramp of the drought.” This fragment of Rebellion in the Backlands written by the Brazilian author Euclides da Cunha sums up perfectly the reality of the Brazilian backlands, the most inhabited semiarid region on the planet. It is characterized by long periods of drought, and, over the years, these periods have been getting longer and more rigorous at the expense of climate change. Therefore, we, articulators of the local core of Feira de Santana of the NGO Engajamundo, an NGO that works with volunteers from all over Brazil about Climate Change, Biodiversity, Global Goals, Habitat and Gender, aim to implement an innovative, sustainable and easily maintained technology in the Brazilian semiarid Northeastern communities: a solar-powered desalinator. This device turns brackish water from underground wells into fresh drinking water, thus guaranteeing, for the first time in many communities, water security and providing social transformation, using the clean and renewable energy of the Brazilian Northeastern symbol, the Sun.
