do the math on the Alternator in series with the losses on the electric brush motor.
they are both very wasteful, and in series they are pathetic.
start with a drop of gasoline can work that to the spinning blade (you will not err)

if your car is in Arizona and you drive in bumper to bumper traffic. for hours.
it is ,in fact ,wasting way more energy, then a simple direct drive flex fan.

so consider where you live too. and driving predominance's.

but thinking one is better than another , well that depends.
for MPG , then one that works best is the one that works the least.
and for many , its working full time all summer long.

all engineering is a compromise.

cheers
