100 Mile Per Gallon Plug-In Hybrid Van 

A spinoff from the Rocky Mountain Institute, Bright Automotive, has developed a 100-miles-per-gallon plug-in hybrid.

Last week, Bright Automotive, a startup based in Anderson, IN, unveiled a plug-in hybrid utility van designed to travel 50 miles on half a gallon of gasoline. The company plans to start producing the Idea vehicle in large volume by the end of 2012, and it hopes to sell 50,000 a year starting in 2013.
