What is Solar water distillation?

"Solar water distillation is the process of using energy from the sunlight to separate freshwater from salts or other contaminants."

"Solar distillation units can be used to remove salts from water. The basic design consists of a shallow, covered trough. The water evaporates from the brine and condenses on a plate over the collecting trough. For a high-efficiency solar still one should have high solar radiation, high air temperature, low wind velocity, and a small condenser surface (Daniels, 1975)."

"NMSU Assoc. Professor Kenny Stevens talks about homemade solar water distillers, which use evaporation and condensation to purify water."

"Passive solar water distillation is an inexpensive, low-tech alternative for pure drinking water without bottles, including types of distillers, cost comparisons, going automatic or electric."

"Solar distillation is a means of converting contaminated or brackish water into potable water. According to the World Health Organization, nearly 1 billion people lack access to safe drinking water"

"Distillation is a simple process, although it can be difficult to accomplish in quantity. It consists of heating the water to the point where it evaporates quickly or steam forms. Then, that water vapor is captured and cooled, allowing it to condense back to water.

The really great thing about distillation is that nothing else evaporates with the water."

"Solar distillation is the use of solar energy to evaporate water and collect its condensate within the same closed system. Unlike other forms of water purification it can turn salt or brackish water into fresh drinking water (i.e. desalination)."
