I think this idea ranks up there with putting an alternator in an electric vehicle to charge the batteries as you drive.  |
*The mechanical efficiency of the turbine would around 80%.
*The mechanical efficiency of the generator might be 98%.
*Combined,for every 746-Watts of power extracted,you'd have to overcome 964-Watts of drag for the turbine alone,then add in the drag of the nacelle,supporting strut,interference drag at the attachment interface,plus you'd be driving in the turbulent wake of the turbine; of which it's kinetic energy could never be converted back to useful pressure,disturbing local body airflow,increasing the car's overall aerodynamic drag.
*Think of a side-view mirror the size of the rotating disc of the turbine!
*It could be the poster child for Entropy.
