of course
the Zenn motor company which did make an electric car, and then quit and invested in a new battery tech development is still trying to get that straight. Scientists can talk talk talk but sometimes don't deliver and string it out painfullly long, could be what has happened to Zenn. Everybody is working on the invention of longer more powerful battery...one that holds charges much much longer....it would be great but you know what they will charge a lot for them won't they?!
