After 18 months of not building any vehicles, plug-in vehicle company Fisker finally threw in the Chapter 11 towel today, filing for bankruptcy protection. The Department of Energy sold its Fisker assets to Hybrid Tech Holdings LLC for $25 million, at a reported $139-million loss. Other reports say the DOE invested $192 million in Fisker, and only got around $53 million back. The DOE put Fisker up for auction last month. Fisker also apparently owes creditors up to a billion dollars. Whatever the exact figures, the point is that the Fisker saga now enters a new phase.
