In the report Fog Collection by Mimicking Nature, published in the 2010 Journal of Biomimetics, Biomaterials and Tissue Engineering, Ahmad and other co-writers describe how the beetle travels to the top of sand dunes laden with early morning fog. The fog water droplets are attracted to the top of micro bumps on the exoskeleton of the beetle, and the drops then roll down to the waxy troughs, delivering very small amounts of water at a time. The micro bumps are hydrophilic, which means they readily absorb water and the troughs are hydrophobic; that is, they repel water. These troughs are filled with nanopores, micro fluid channels and nano wax crystallites. Droplets with 15-20 micrometer diameters are attracted by the micro bumps and roll down the troughs on the beetle‘s back. These rolling drops eventually fall into the beetle‘s mouth as it pushes its mouth backward to obtain water. ―The design of our fog collector is based on creating a nano-micro hybrid surface structure, which mimics the skin of the desert beetle,‖ Ahmad explains. He added that as soon as the fog comes in contact with the stainless steel meshed net, water droplets start to form and roll down the drainage channel and collect in a water tank down the slope of the sand dunes. Underground PTFE water storage tanks with hand pumps are recommended to prevent contamination by dust and sand. The water is then filtered through rubber tire powder, making it pathogen free and suitable for human consumption. He said this method, although initially costly, offers a sustainable fog collecting system that can be adopted for arid and semi-arid regions of Pakistan and similar areas. ―Pakistan Researchers Use Nanotechnology to Make Water From Fog ―, 01/08/<strong>2012</strong>, online at: http://www.ooskanews.com/daily-water-briefing/pakistan-researchers-use-nanotechnology-make-water-fog_23660 BACK TO TOP Page 67
China Water Signs Joint Venture With Henan Province BEIJING (China Daily) — China Water Affairs Group Ltd, a provider of water and sewage treatment, has agreed to establish a joint venture that will be involved in water-related investments and construction in Henan province and nearby provinces. Jianghe Water Affairs Co, a unit of China Water, plans to invest $21.2 million USD and own a 45 percent stake in the venture. The remaining portion of the company will be held by Henan Water Resources Construction Investment Co and Huanghe Water Affairs Co, China Water said in a Hong Kong Stock Exchange filing. "The potential for the water business in Henan province and adjacent areas is booming," the Beijing company said on Monday. Projects related to water resources are now under way in the Yellow River basin, as is the South-North Water Diversion project. ―China Water Signs Joint Venture With Henan Province‖, 02/08/<strong>2012</strong>, online at: http://www.ooskanews.com/dailywater-briefing/china-water-signs-joint-venture-henan-province_23685 BACK TO TOP Page 68
