Clean drinking water from saltwater and sunlight

Eliodomestico

Salt water is poured into the top container, which then gets heated by the sun and converted to steam by solar energy. The increase in pressure forces the steam to travel through a tube to the lower container where it re-condenses. The clean drinking water gathers at the bottom of the lower container.
