Wally Tyner Seminar Seminar on Nov. 18, 2011
November 19, 2011
The Energy Center was pleased that Wally Tyner, Co-Chair of the National Academy of Sciences Committee on Economic and Environmental Impacts of Increasing Biofuels Production, agreed to provide a seminar on this important study on Friday, November 18, 2011 at noon in Pfendler Hall. Maureen McCann, Director of the Energy Center, introduced him to a "standing room only" crowd.
Wally provided an informative summary of the major findings from the study released by the National Research Council of the National Academy of Sciences in October of 2011. Perhaps the most controversial finding was that the U.S. is unlikely to meet the Renewable Fuel Standard (RFS) for 2022 for cellulosic biofuels. Wally will provide a description of the data and analysis underlying this conclusion. Another controversial finding was that the RFS may not be an effective way to reduce GHG emissions. The background for this finding will be reviewed as well. In addition, he reviewed the committee’s assessment of impacts on food and feed prices, land values, government budget, environmental impacts, and other areas. He closed after 45 minutes and fielded several questions from the audience.
If you were unable to attend the lecture, you may download his presentation at the following link: presentation. A video of his presentation will be posted soon.
The full report is available online at no charge in pdf format. Site registration is required. Additional information regarding the study and its release in Washington, DC last month, may be found in the Purdue news story.

The recent recall of hoverboards because of exploding lithium-ion batteries highlights the danger of overheating batteries. Amy Marconnet, an assistant professor of mechanical engineering, can speak about the effects of excessive heating in batteries. Marconnet (pronounced mar-co-nay) founded the Marconnet Thermal and Energy Conversion Lab, where researchers are dissecting the batteries and testing materials making up electrodes and a critical component called a separator. (A video is available at https://www.youtube.com/watch?v=qCTMA8sxZO0) Battery failures have been reported in products ranging from commercial airliners and laptops to hoverboards and cellphones. Chemical reactions in the batteries generate heat while discharging and charging. The separator is a layer of material between the positive and negative electrodes. When it fails due to high heat, the battery short-circuits and could explode.Read Full Story
