If you can solve any of these, you can be rich! Fog harvesting is an interesting possible solution, depending on conditions. The writeup I just looked at claimed 3 liters of water per day from a 1 meter section of fog harvester. The fog harvester is basically a piece of landscaping fabric held between posts "blocking" any prevailing wind. The fog condenses on the fabric and drips off the bottom of the fabric into a trough. 30 seconds of research left me with 2 older but interesting articles. http://www.idrc.ca/reports/read_article_english.cfm?article_num=284 http://www.unep.or.jp/ietc/Publications/TechPublications/TechPub-8c/fog.asp I read something about fog harvesting in a recent periodical, I of course forget what magazine, which used a fine wire set up in a mesh similar to a large spider web, as the fog harvester. kirk *************************************************************************** PaddleWise Paddling Mailing List - Any opinions or suggestions expressed here are solely those of the writer(s).
