I have been installing similar technology for our community extension projects. . .
Researchers at Ulsan National Institute of Science & Technology have created a novel solar desalination system that converts seawater into freshwater using sunlight and advanced materials—without needing grid electricity or batteries. At the heart of the system is a photothermal perovskite material that efficiently heats water, while a cleverly designed flow path directs salt crystals to the edges, preventing buildup and maintaining high efficiency. The system has achieved an evaporation rate of approximately 3.4 kg of water per square meter per hour with solutions at 20% salinity—far higher than typical seawater.
The breakthrough lies not just in using solar energy for evaporation but in the salt-rejection design, which addresses a major challenge in long-term desalination systems. By combining the advanced material with an inverse-L shaped water wicking path, the system sustains performance without frequent cleaning or maintenance. Researchers describe it as both practical and scalable, offering potential solutions for regions facing water scarcity and unreliable electricity.
Though still experimental, this technology shows promise for low-cost, off-grid freshwater generation in remote or arid areas. Future efforts will focus on scaling the system, testing durability in real-world conditions, and assessing full lifecycle costs for widespread deployment.
It shifts your focus away from anxious or looping thoughts.
