Scientists, Environmentalists Spar Over Nanotechnology: "Like biotechnology before it, nanotechnology is stirring up opposition from environmentalists concerned about the unintended consequences -- on the Earth and in our bodies -- of setting loose molecule-sized machines and devices."  11:15:36 PM  permalink  

Nanotechnology May Aid Environment: "The National Science has been cutting its timetable for the release of nanotech-fueled products from five or 10 years to two or three years, said Mihail Roco, NSF's senior adviser on nanotechnology. Roco envisions a $1 trillion yearly market in products that carry nano-components, including all computer chips, half of pharmaceuticals and half of chemical catalysts. The current state of nanotechnology mirrors the level of development in the field of polymers and plastics in the 1930s, when it was in its infancy, said Kevin Ausman, director of the Rice University Center for Biological and Environmental Nanotechnology. ..

For scientists who study it, nanotechnology is considered a clean technology — perhaps even the key to solving some current environmental ills. .. for instance, filter systems for drinking or waste water, natural gas pipelines and smokestacks can be designed at the molecular level, to remove even the most minuscule of impurities... Nanoparticles are also being examined for use as sensors to monitor air or drinking water for the presence of toxins. .. Pollution-absorbing nanoparticles that can be used to clean up tainted water or soil is another concept under study, Roco said. And the entire concept of nanotechnology — building devices at the molecular level — means that products will be smaller. There is less waste in the production process and in the trash, when nano-devices are discarded at the end of their lives, Roco said. "
