UA Science Cafe at Borderlands Brewing – 'Water Desalination Using High Concentration Photovoltaics'
Series topic: Aquifers to Zika: Biotic and Abiotic Issues in Conservation
Environmental conservation encompasses a wide range of concerns, from preventing epidemics to establishing sustainable water sources, from animal conservation to predicting climate change. In this series four Carson scholars will examine how genomics, entomology, photovoltaics, and citizen science can be used to address the wide breadth of environmental challenges that our world faces today.
Talk: "Water Desalination Using High Concentration Photovoltaics: Water, Energy and Food Security for Underserved Populations in the Most Arid Regions of the World"
Presenter: Rodolfo Peon, Ph.D. student, Arid Lands Resource Sciences
Talk description: By the year 2030, about half of world's population will be living in areas of high water stress. Being agriculture the largest water consumer, food production will be extremely challenging in the future. Taking the Navajo Nation as a case study, it is shown that treatment of saline aquifers with small-scale solar desalination technologies can provide end users with sufficient water and energy to meet their needs and grow food all year round.
