How a Solar Still Works - Clean Water from Sunlight #3310656 (License: Personal Use)

This line-art diagram depicts a basic solar still, where ambient or solar energy heats impure water in a basin, causing evaporation. The resulting water vapor rises, contacts the cooler angled transparent cover, condenses into liquid, and flows down channels into a clean collection area. The design is passive, requiring no electricity, making it valuable in remote or disaster-affected regions.

Used on educational, sustainability, and prepping websites to explain water purification methods; matches user intent for learning about off-grid water solutions, survival techniques, or renewable desalination.
