Electric-car start-up Better Place declared bankruptcy this week, joining a pile of broken EV dream companies that includes Fisker Automotive, among many others.

In this video, Fool contributor John Rosevear looks at why Better Place and other EV pioneers have failed -- and at why Tesla Motors (TSLA -1.92%) has been the one shining exception to the trend.
