I was reading an article in the latest Water World Magazine and wanted to pass along to you.  A group of engineers at the University of Arizona in conjunction with Apex Applied Technology converted an old School Bus into a Desalination Plant for an off-the grid school in the water-scarce Navajo community.  The title of the article is  Solar Desalination Bus Delivers Drinking Water to Navajo Community.
