  Water extraction from air humidity revisited – did we find the Holy Grail?

  Let me start with facts that some of you are already familiar with.
  
  Robert Nelson published a pretty good research of methods for recovery of atmospheric humidity (http://www.rexresearch.com/airwells/airwells.htm), in which he also describes the atmospheric rivers that distribute water and have a determinant influence on the location of rainfall.
  
  Approximately 13,000km3 of water are in the atmosphere at any given time: 98% in the form of vapors and only 2% as clouds. Nature continually recharges the atmosphere with moisture by evaporation from the world’s oceans, seas and fresh water bodies. But this potential life-giving huge water reservoir is virtually untapped – except for the natural (and inadequately distributed) phenomenon of precipitations.
  
  The methods described by Nelson have not gained widespread use for various reasons – complexity, cost, usability, efficiency, etc...
  
  A novel breakthrough and cost effective process, based on the dry adsorption of atmospheric humidity and the use of heat, enables to extract large amounts of potable water from the air, even in arid zones. Furthermore, since the main energy required is heat, renewable energy sources such as waste incineration or solar collectors are offered to power a sustainable water and energy cycle. As for the environmental impact of the process, the air coming out of the system is slightly warmer than the ambient air, and naturally flows upwards to be replaced by “fresh” air. This can be considered as very targeted and practical rain supplement, for areas where the climate does not produce enough rain and where other water sources are lacking.
  
  This might sound like the Holy Grail, yet it is real and already operating and producing water in over 50 sites. Consider the following parameters: Production cost of about $0.50 per cubic meter (1000 litres); Production capacity of up to 1000 cubic meters per day (largest plant); Operational in very dry climates (20% relative humidity and upwards); Temperature range of 4c to 45c; Low capital investment; Simple and mostly unattended operation; Robust and resilient construction that withstands harsh environments.
  
  Interested? Intrigued? I’d like to hear from you.

  Re: Water extraction from air humidity revisited – did we find the Holy Grail?

  Rather interesting post! I moved to tha Baja California Peninsula in Mexico where water is treasured. Most of the water supply comes from the underground reservoirs and they are already proven to be insufficient for the constantly growing population. The government is starting plans for a desalination plant, but both bueaucracy and high costs have made this a slow venture. My question would be: is the humidity extraction method more expensive than the desalination one? Solar power sounds great as a sustainable energy source, for we have sunny days almost al year long. Thank you for sharing!!!!!

  Actually this technology produces water at about the same cost as desalination, but without the waste (brine) resulting from desalination nor the infrastructure. If you have a concrete interest or access to potetial users, add me as a direct contact and I'll send you an overview.
