2. Solar still - Wikipedia

   en.wikipedia.org/wiki/Solar_still

   A pit still may be too inefficient as a survival still, because of the energy/water required for construction. [9] In desert environments water needs can exceed 3.8 litres (1 US gal) per day for a person at rest, while still production may average only 240 millilitres (8 US fl oz).

3. Slingshot (water vapor distillation system) - Wikipedia

   en.wikipedia.org/wiki/Slingshot_(water_vapor...

   Slingshot is a water purification device created by inventor Dean Kamen. [1] Powered by a Stirling engine running on a combustible fuel source, it claims to be able to produce drinking water from almost any source [2] by means of vapor compression distillation, [3] requires no filters, and can operate using cow dung as fuel.

4. Solar desalination - Wikipedia

   en.wikipedia.org/wiki/Solar_desalination

   Solar stills of this type are described in survival guides, provided in marine survival kits, and employed in many small desalination and distillation plants. Water production is proportional to the area of the solar surface and solar incidence angle and has an average estimated value of 3–4 litres per square metre (0.074–0.098 US gal/sq ft ...

5. Solar-powered desalination unit - Wikipedia

   en.wikipedia.org/wiki/Solar-powered_desalination...

   Indirect solar desalination systems comprise two sub-systems: a solar collection system and a desalination system. The solar collection system is used, either to collect heat using solar collectors and supply it via a heat exchanger to a thermal desalination process, or to convert electromagnetic solar radiation to electricity using photovoltaic cells to power an electricity-driven ...

6. Multiple-effect distillation - Wikipedia

   en.wikipedia.org/wiki/Multiple-effect_distillation

   Multiple-effect distillation or multi-effect distillation (MED) is a distillation process often used for sea water desalination. It consists of multiple stages or "effects". In each stage the feed water is heated by steam in tubes, usually by spraying saline water onto them.

7. Atmospheric water generator - Wikipedia

   en.wikipedia.org/wiki/Atmospheric_water_generator

   State-of-the-art AWG for home use. An atmospheric water generator (AWG), is a device that extracts water from humid ambient air, producing potable water. Water vapor in the air can be extracted either by condensation - cooling the air below its dew point, exposing the air to desiccants, using membranes that only pass water vapor, collecting fog, [1] or pressurizing the air.
