That video is about a show car, and it says the technology will show up in he 2010 model year. But it didn't happen. Electric cars face big challenges in terms of cost and weight; I expect that a design like this, which increases both, is far, far away. The Tesla cars, which cost a huge amount of money, don't do things this way. The Toyota hybrid system, probably the most developed in the world at the moment, doesn't do things this way. The people who designed those things were smart people.
