Earlier this week, I received a phone call from a site visitor with connections to Kenya. He inquired whether water-from-air machines might be suitable for producing drinking water for livestock in drought-stricken NE Kenya. I had a general idea that the atmosphere in this region contains a lot of moisture, even during droughts, but wanted to quantify my response as much as possible. So I proceeded to use a mathematical model I've developed to quantify the amount of water a water-from-air machine with 40 Tons of refrigeration capacity* could produce each day in the drought region. In NE Kenya, about 2000-2500 L per day could be produced with fairly steady production through the year. Now my site visitor has to decide whether or not the capital and operating costs of water-from-air are competitive with the few remaining water source alternatives in the region. Interesting and exciting possibilities for helping people and their livestock manage through a very serious drought situation... * Such machines are available through my related company Canadian Dew Technologies Inc.; www.candew.ca CommentsLeave a Reply | Roland Wahlgren
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. ArchivesApril 2012 CategoriesAll   |
