Water Filters Rely on Nanotech: Report from the October 2004 NanoWater conference. "A slow, methodical transformation of the $400-billion-a-year water-management industry is currently in progress, and nanotechnology appears to be leading the way. .. Two products incorporating nanotechnology are going to hit the market within the next year and are already being tested in developing nations. .. Matrikx water filters will be on store shelves within the next year after already having experienced success in 50 pilot programs throughout central Asia.  Argonide's president, Fred Tepper, is trying to get his product in the hands of consumers in the next 60 to 90 days, he said, having recently secured a distribution deal with a European company ..

Though these breakthroughs seem cutting-edge, the technology is not terribly new. Water-treatment plants have been using nanofiltration and ultrafiltration membranes to separate good water from bad for more than five years. And already the technology is becoming the industry standard. .. The same technology is allowing desalination -- the process of removing salts from fresh or sea water -- to occur at a much greater rate. The largest desalination plant in the world will begin operating in Ashkelon, Israel, in March 2005."

Argonide Nanomaterials has an interesting history of collaborations with US govt labs, Russian institutes active in nanotechnology, and others in Italy, Japan, and Singapore.

Development Through Enterprise: New web site, NextBillion.Net, with multiple author blogs. "Our goal is to identify and discuss sustainable business models that address the needs of the world's poorest citizens."  High quality content, looks like a good model for collaborative blog/infohub.  12:11:50 PM  permalink  

Soros funds mesh nets: "The Champaign-Urbana Community Wireless Network (CUWiN) has been awarded a $200,000 grant from the Open Society Institute, funded by the Soros Foundation, to develop wireless technology to be used around the globe, with a focus on developing nations. The result will be the most advanced community wireless technology in the world. "  OJC Technologies is doing the implementation under contract.  CUWIN has released an open source beta: "Imagine a free wireless networking system that any municipality, company, or group of neighbors could easily set up themselves. Over the past half-decade, the Champaign-Urbana Community Wireless Network (CUWiN) has been developing an open source, turnkey wireless networking solution that exceeds the functionality of many proprietary systems. CUWiN's vision is ubiquitous, extremely high-speed, low-cost networking for every community and constituency."  More background: "To set up a CUWiN network, you burn a CD with the 0.5.5 software later this week and use it to boot a computer with a supported wireless card. The system finds nearby nodes, creates tables, and establishes itself as part of the network. The software is free and open source. "  8:21:32 AM  permalink
