Why does a solar-powered water still might be useful in a country where the drinking water contains bacteria that can cause diseases?

A solar-powered water still can effectively purify contaminated water by utilizing solar energy to evaporate water, leaving behind harmful bacteria and impurities. This process produces clean, distilled water that is safe for drinking, making it particularly beneficial in regions where access to clean water is limited. By using renewable energy, such systems also provide a sustainable solution, reducing dependence on fossil fuels and minimizing environmental impact. Overall, solar stills can enhance public health by providing a reliable source of safe drinking water.
