A study compares centralized desalination from the Sea of Cortez with atmospheric water harvesting for Arizona's water supply. Desalination focuses on transporting treated seawater over long distances, while atmospheric systems capture moisture from the air, potentially providing localized water sources.
Each method has unique challenges in energy requirements and environmental impact; desalination requires significant power for reverse osmosis and transport, whereas atmospheric systems demand energy for air processing. The decision hinges on a balance between the scale of production, energy efficiency, and governance implications. Arizona may benefit from a hybrid approach that integrates various water sources to enhance resilience and security.
