solar still

A solar still is a device that uses the Sun's energy to convert saltwater into drinkable water. It mimics the Earth's natural water cycle. In a simple solar still, saltwater is heated by the sun, turning into water vapor. This vapor rises, condenses on a cool surface, and collects as fresh water, leaving the salt behind. This process is effective for purification but produces a limited amount of water daily, making it suitable for small-scale needs. Indirect solar desalination combines solar energy with other methods like reverse osmosis for larger-scale production. Solar energy is a renewable resource, but its use in desalination is dependent on weather conditions.123
