Water-Gen, an Israeli company, has developed a new Atmospheric Water-Generation Unit using its “GENius” heat exchanger to chill air and condense water vapor. The clean air enters their GENius heat exchanger system where it is dehumidified, removing the water from the air and directing it to a collection tank inside the unit. The water is then passed through a water filtration system which cleans it from possible chemical and microbiological contamination.  What sets this water generator apart from others on the market is that it is more energy efficient than others by using the cooled air created by the unit to chill incoming air. The system produces 250-800 liters (65-210 gallons) of potable water a day depending on temperature and humidity conditions and is reported to use two cents’ worth of electricity to produce a liter of water. This is equivalent to 1.5 Rupees, as opposed to 15 Rupees for a liter of bottled water. I read some comments to this article mentioning that if the electricity could be generated using solar power this unit could be extremely useful.
