I HAVE had a thought regarding propulsion by environmentally-friendly means.

I am thinking of a car with no traditional piston engine at all but with dynamos in the hub of the wheels be it four wheels or two. Of course, it would have a battery for the initial take off then, thereafter, the dynamos would be engaged for the journey.

I am not an engineer myself and I would welcome being shot down by an expert engineer as to why this is not practical. I look forward to any comments.
