Solar still design involves harnessing the sun’s energy to evaporate and condense water, producing purified water from saline sources. The design process considers factors such as the amount of sunlight, temperature, and the size and shape of the still, to optimize water production. Researchers, industry leaders, and academic institutions collaborate to advance solar still technologies, focusing on efficiency, scalability, and cost-effectiveness. These efforts aim to address global water scarcity and provide sustainable desalination solutions for communities in need.
