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.
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.
The compression is mechanically powered by something such as a compression turbine. As vapor is generated, it is passed over to a heat exchanging condenser which returns the vapor to water. The resulting fresh water is moved to storage while the heat removed during condensation is transmitted to the remaining feedstock.
Water vapor, water vapour or aqueous vapor is the gaseous phase of water. It is one state of water within the hydrosphere. Water vapor can be produced from the evaporation or boiling of liquid water or from the sublimation of ice. Water vapor is transparent, like most constituents of the atmosphere. [1]
A vacuum coffee maker. Industrial design-classic by Abram Games. A vacuum coffee maker brews coffee using two chambers where vapor pressure and gravity produce coffee.This type of coffee maker is also known as vac pot, siphon or syphon coffee maker, and was invented by Loeff of Berlin in the 1830s.
The water vapor is continuously evacuated from the VIM, compressed, and fed into a condenser due to the special construction of the centrifugal compressor. A standard water chiller supplies cooling water at 5 °C in order to condense the water vapor. The liquid-ice mixture is pumped out from the freezing volume to the ice concentrator in which ...
At this pressure, the condensation temperature of the water vapor at the heat exchanger will be 390 K. Taking into account the boiling point elevation of the salt water we wish to evaporate (8 K for a saturated salt solution), this leaves a temperature difference of less than 8 K at the heat exchanger. A small ∆T leads to slow heat transfer ...
A fog machine, fog generator, or smoke machine is a device that emits a dense vapor that appears similar to fog or smoke.This artificial fog is most commonly used in professional entertainment applications, but smaller, more affordable fog machines are becoming common for personal use.
