Southeast of San Francisco, on the way out to California's Central Valley, thousands of wind turbines dot the landscape of Altamont Pass. Mounted both in rows and individually, machines with large propellers catch the wind, turning round and round at different speeds. Learn how wind energy is generated and stored for use in this most peculiar area, and its impact on living things both near and far. Julia Moore and Evan Michelson of the Woodrow Wilson International Center for Scholars talk about nanotechnology products they’ve found for sale in a variety of stores. Should these products have some sort of special label? Journalist Philip Ball also weighs in on the controversy. Dr. Jim Tour, a chemist at Rice University, builds the world’s smallest vehicles. He calls them “nanocars,” and he thinks these tiny vehicles might lead to nano-sized factories. We’ll also hear from University of Florida graduate student Diane Hickey, who will tell us some of the interesting reactions she’s run into when explaining nanotechnology. Join us as we speak with IBM Fellow Dr. Don Eigler, who first used a scanning tunneling microscope to demonstrate the ability to build structures at the atomic level by spelling “I-B-M” with individual atoms. Also, meet Tom Rockwell, Director of Public Exhibition at the Exploratorium, who describes, in an audio essay, how he imagines the land of the very small.
