One way to think about this is if you took the turbine off the car, put it in your yard, and used it to charge batteries. That would work, wouldn't it? So why wouldn't it work with the turbine on the car? Of course efficiency is another matter :-)

How do you separate it from the drag induced by said wind? Even if the turbine is 100% efficient, that nets 0 gain.
