2. 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.

3. Kelvin water dropper - Wikipedia

   en.wikipedia.org/wiki/Kelvin_water_dropper

   The Kelvin water dropper, invented by Scottish scientist William Thomson (Lord Kelvin) in 1867, [1] is a type of electrostatic generator. Kelvin referred to the device as his water-dropping condenser. The apparatus is variously called the Kelvin hydroelectric generator, the Kelvin electrostatic generator, or Lord Kelvin's thunderstorm.

4. Watermaker - Wikipedia

   en.wikipedia.org/wiki/Watermaker

   A watermaker is a device used to obtain potable water by reverse osmosis of seawater. In boating and yachting circles, desalinators are often referred to as "watermakers".. The devices can be expensive to acquire and maintain, but are quite valuable because they reduce the need for large water tanks for a long passage.

5. Dehumidifier - Wikipedia

   en.wikipedia.org/wiki/Dehumidifier

   Unlike in distilled water production, the water is not boiled, which would kill pathogens (including bacteria). As with distilled water, beneficial minerals are largely absent. Food-grade dehumidifiers, also called atmospheric water generators, are specifically designed to avoid toxic metal contamination and to keep all water contact surfaces ...

6. Thermoelectric generator - Wikipedia

   en.wikipedia.org/wiki/Thermoelectric_generator

   In motor vehicle applications a supplementary radiator is sometimes used for improved heat removal, though the use of an electric water pump to circulate a coolant adds parasitic loss to total generator output power. Water cooling the thermoelectric generator's cold side, as when generating thermoelectric power from the hot crankcase of an ...

7. 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.

8. Water heat recycling - Wikipedia

   en.wikipedia.org/wiki/Water_heat_recycling

   Installation of a double-walled copper-on-copper heat exchanger in a vertical section of the master drain line in a Canadian home (2007) Water heat recycling (also known as drain water heat recovery, waste water heat recovery, greywater heat recovery, [citation needed] or sometimes shower water heat recovery [citation needed]) is the use of a heat exchanger to recover energy and reuse heat ...

9. Boiler (power generation) - Wikipedia

   en.wikipedia.org/wiki/Boiler_(power_generation)

   A boiler or steam generator is a device used to create steam by applying heat energy to water. Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi ) but, at pressures above this, it is more usual to speak of a ...
