Hydrogen Road Tour
August 11, 2008
US Dept of Transportation: August 11, 2008: America Gets New Glimpse of Hydrogen Powered Future During Historic Two Week Road Tour Across the United States -- Americans will have a unique opportunity to see what the future holds for hydrogen in the United States with the launch of an historic two-week, cross country trek of a fleet of clean, efficient hydrogen vehicles.
Nine auto manufacturers, the U.S. Department of Energy, California Fuel Cell Partnership, National Hydrogen Association, and U.S. DOT are sponsoring the Hydrogen Road Tour to show that hydrogen vehicle and fueling technologies are approaching commercial availability, even as new research and development breakthroughs continue.

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
