solar I agree with. But we're weighing the effiency of a belt driven alternator with the efficiency oooof...
...the transmission driven tires to the tire driven vehicle to the vehicle created airflow to the airflow created propeller to the propeller driven alternator.
as for the chain of efficiency losses, just the tires at speed have a bigger loss than the alternator belt.
