This new device generates clean water vapour from salty or dirty water using sunlight and a light-absorbing material that does not require contact with water. Instead of heating water directly, the material heats black paint that produces infrared light. Water beneath the device absorbs the infrared light, heats, and vaporizes. The no-contact system avoids contamination and cleans water for longer operating times.
