Recent legislation in Mauritius demands hotels and "major hospitality centres" have desalination plants. Could water-from-air systems be considered as an alternative to desalination plants at some sites?
A news item about the company, Water Resources Group, expanding, "its licence relationship with Mandala Water to include The Republic of Mauritius,..." for desalination plants prompted me to produce a water-from-air resource chart for Port Louis, Mauritius. Annually, water vapour density ranges from a high of 20.4 grams per cubic metre in February to a low of 13.5 grams per cubic metre in July and August. Conditions are excellent for water-from-air production from November to May. Conditions are rated "good" for atmospheric water generator operation during the balance of the year. Details are available in the Port Louis chart.

How much interest is there in water-from-air technology? Wikipedia provides page view statistics for its articles. These statistics provided a crude estimate of interest from the English-reading, Internet-using public. Here is the table I assembled, with twenty-eight Wikipedia articles listed in order of page views in the last 30 days as of April 10, 2012. I started with the reference list in the Atmospheric water generator article. As I went from one referenced article to the other a point was reached when no new relevant references were found. The hierarchy of public interest in these related topics was made evident. The water cycle must be a popular topic in schools! The article Atmospheric water generator, with 4178 page views was of most interest because that terminology has become widely used to describe commercial machines that produce drinking water from the ambient air. The article, Desalination, had a much higher profile, attracting 10 times as many page views. For those of us seeking to raise the profile of water-from-air technology---we have a lot of work to do given only 100 to 150 people viewed the AWG article each day. How many read it is another matter! (By the way, I have not been a contributor to Wikipedia articles.) Table: Water-from-air relevant topics in Wikipedia

I have been researching and developing drinking-water-from-air technologies since 1984. As a physical geographer, I strive to contribute an accurate, scientific point-of-view to the field. Archives
