Bloomberg Businessweek throws out a little bad news, which President Obama will of course completely ignore during his health-care victory lap: “Abound Solar Inc., a U.S. solar manufacturer that was awarded a $400 million U.S. loan guarantee, is closing its doors and filing for bankruptcy, according to the U.S. Energy Department.”

Abound Solar was based in Colorado. The Denver Post adds some details about the failure of its business model: “Abound has been struggling with the falling price of solar panels. The company’s technology made a solar cell out of a piece of glass by applying a thin film of chemical to it. It was supposed to be cheaper than traditional silicon panels, but since 2009 the price of those panels has dropped from $2.79 a watt to less than $1, according to industry consultant Solarbuzz.”
