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.
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 ...
An 80 US gal (300 L; 67 imp gal) electric storage tank water heater was able to have a minimum energy factor of 86% under the pre-2015 standard, while under the 2015 standard, the minimum energy factor for an 80-gallon electric storage tank water heater is now 197%, which is only possible with heat pump technology. This rating measures ...
The device was detailed in a study, titled ‘A solar-driven atmospheric water extractor for off-grid freshwater generation and irrigation’, which was published in the journal Nature Communications.
The first type of lithium bromide absorption heat pump unit is a high-temperature heat source (steam, high-temperature hot water, fuel oil, gas) as the driving heat source, lithium bromide solution as the absorbent, and water as the refrigerant, and the low-temperature heat source (such as waste hot water) is recycled and used.

A bioactive compound is a compound that has an effect on a living organism, tissue or cell, usually demonstrated by basic research in vitro or in vivo in the laboratory. While dietary nutrients are essential to life, bioactive compounds have not been proved to be essential – as the body can function without them – or because their actions are obscured by nutrients fulfilling the function.
Solar heat is clean and renewable. This is the most modern system. Increasingly, solar powered water heaters are being used. Their solar thermal collectors are installed outside dwellings, typically on the roof or walls or nearby, and the potable hot water storage tank is typically a pre-existing or new conventional water heater, or a water heater specifically designed for solar thermal.
Solid state fermentation uses culture substrates with low water levels (reduced water activity), which is particularly appropriate for mould. The methods used to grow filamentous fungi using solid state fermentation allow the best reproduction of their natural environment. The medium is saturated with water but little of it is free-flowing.
