Question from a car enthusiast: do you see potential in a car like the Volt but instead of using a gas engine to make more electricity, using a fuel cell once the on board batteries are depleted? I've been quite hopeful that range extended electic vehicles are an important part of the future, and while so far we've only seen gasoline powered generating stations, I can think of no limitations on using a fuel cell. I'm thinking of a 200miles range Tesla adding another 100 miles with a fuel cell.

The current problem with most production electric cars is not the drive, the handling or the capability...it's that you need a conventional car as a back up for emergencies unless you are driving a Volt. The Leaf is a fantastic little thing but most useful as a weekday runabout for errands.
