Somehow there is an assumtion that the normal streamlining of a vehicle
produces more drag than your rotor does even while extracting energy. That
is hard to believe especially when you realize that most of the vehicle is
still there and still produces drag when the rotor is added. The sum of the
rotor plus the streamlined car has to be greater than the streamlined car
alone, right? If not, why not? What we need (or you need) are actual numbers
calculated or measured that illustrate your point.

What is the drag of a normal car? What is the power required to move that
car at 65MPH? What is the drag of the rotor plus the car at the same speed
and what total power is required to move it at that speed? How much power is
extracted from the engine to drive the alternator? How much additional drag
does the rotor create when developing that alternator power?

I believe that if you use actual numbers, the rotor scheme will be found to
consume much more total power than any automotive system without it,
including the alternator, under the same conditions. Your system violates
the free lunch law.
