J. Bonasia of Investorโs Business Daily gives a variety of nanotech perspectives from the Foresight Conference:
โFor now, green advocates appear to be cautiously optimistic about the technology. Many see it as a way to cut pollution and relieve human suffering. But they want to carefully assess nanotechnology as it evolves. โNanotech is not understood by most Americans,โ said Adam Werbach, former president of the Sierra Club, at an event hosted by the Foresight Nanotech Institute. โThis is the critical moment to encourage social debateโโฆ
โThe stakes are high enough that nanotech firms should take extra steps to safeguard their work, warns Randy Hayes, head of the Rainforest Action Network. The rapid rise of nanotech could outpace government efforts to protect public health, he says. โWe cannot afford to have slow solutions to fast problems,โ Hayes said. He noted the risks created by past use of asbestos, lead and the pesticide DDTโฆ
โThe Foresight Nanotech Institute, based in Palo Alto, Calif., looks to keep nanotech on the right track. That includes reducing โnanotoxicsโ and other health threats, says Scott Mize, president of the group. โLike all technology throughout history, we need to understand the risks,โ he said. โWe canโt eliminate them completely, but we can reduce them through responsible actionโโฆ
โAnd researchers are reviewing the impact of products throughout their life cycle. That means they check everything from development to disposal, says Shannon Lloyd of First Environments, a consulting firm in Washington, D.Cโฆ
โResearchers are watching for โnanotoxicologyโ โ a term coined this year. The idea is to avoid nano materials that could be harmful. By steering clear of these substances, labs can better focus their research. โThis is a screening tool to reduce the potential for unforeseen impacts,โ said Jo Anne Shatkin, a principal with the Cadmus Group, a consulting firm that studies nanotech risks.
โMeanwhile, many startup firms are using creative nanotech methods to help the environment. For instance, HelioVolt of Austin, Texas, puts nanotech solar panels directly into the walls of buildings for structural support. In this way, builders can conserve materials while generating local power, says B.J. Stanbery, chief executive of HelioVolt. โThis cuts down on the use of traditional building products,โ he said. โThe solar panel becomes the actual building material.โ โ
