Introduction
Template:Stub Solar distillation is the use of solar energy to evaporate water, then collecting the recondensed water vapor.
Often a shallow trough, painted black, and flooded. A slanted pane of glass covering, allowing condensed water vapor to slide down into an output channel. Expect 1 gallon per day per square meter of glass.
In 1999, the average American used 60 gallons of water per day (http://www.aquacraft.com/Publications/resident.htm)
