Purdue Research to Make Solar Energy in Indiana More Viable Option--WBAA
September 29, 2008
WEST LAFAYETTE, IN (2008-09-29) Indiana's expert on electricity consumption thinks solar energy has to be more cost-effective for it to compete with current fuel sources.
State Utility Forecasting Group Director Doug Gotham says it costs about twice as much to get electricity from solar power than coal. He made the comments during testimony to the state's Regulatory Flexibility Committee. Gotham says researchers at Purdue are examining how to make photovoltaic cells less expensive.

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
