Water distillation can be used to obtain safe water to drink using solar energy. Often this involves removing the salt from seawater, which makes up over 95% of the water on the planet, but is also useful in removing contaminants and disease-causing organisms. Most approaches use an evaporation technique. The water is first evaporated, it then condenses and is recaptured as fresh water. Several systems are now using the sun's energy for the evaporation.
Eliodomestico Solar Still
A compact solar still example, is the Eliodomestico Solar Still.
The still heats either salty or dirty water in the upper chamber, steam is created, and fresh water condenses and collects in the lower chamber of the Eliodomestico Solar Still.

Watercone solar still
A simple inexpensive, and mobile device for solar potable water generation from sea water or brackish water based on condensation. With a base diameter of 80 cm (31.5 in), the still is reported to be able to condense roughly one liter of water per day. Read more...
