OK, now what?

I don't follow your point that the resistance from the machine will cost more in gas than it will ever produce.

First, there's no gas in a fully electric car such as I am discussing.

The "machine" would be tucked where the engine normally is so there'd be no air resistance.

I don't understand why, if properly engineered, it could not be used to continuously charge the battery while the car is in motion.

So long as the car is moving you'd generate power to charge the battery / run the vehicle.

I thought my first answer about the perpetual motion machine was enough. I will go down several grades for you. Both the car and the wind generator will have friction losses. Making the generator turn will take power away from moving the vehicle down the road. To account for these losses the wind generator would need to generate more power than the motor of the car uses. Physics tells us that is impossible since power in must equal power out. If you only ever drove down hill you could add enough energy from gravity to make it work.

How is it that "making the generator turn will take power away from moving the vehicle down the road" when the air would otherwise be meeting resistance anyway when it hits the car body?

The presence of moving air is a given.

Whatever, no need for you to deign to respond: I'll consult outside sources of information.

The generator is attached to the vehicle and being dragged through the air. Do you not think a large sail attached to the vehicle would not slow down the vehicle? The car manufacturers spend millions making cars as aerodynamic possible do you really think the wind generator doesn't effect the aerodynamics of the vehicle.

I believe you over-estimate the effect of drag in the scenario I posit, where the generator is tucked in the engine bay behind where the radiator would be.

The air is rushing through there anyway, why not take advantage of it?

Why do dragsters release parachutes to slow down?

It is the same reason you cannot have an EV driven by the front wheels being recharged by the turning of the rear wheels.

Is there more tension in the spring of a wound up grandfather clock then there was in the effort taken to wind the clock up, or did it take more energy to wind the clock than is stored in the wound up mainspring. It takes a certain amount of energy to set a bear trap, but it seems like there is far more energy in the set trap than the energy used to set it.

The setting of the bear trap takes a longer time than the release of the bear trap. The faster the stored energy is released the greater the power. 1 watt is a release of 1 joule/sec. Faster the release the more watts of power created even if the joules of energy don't increase.

A quick google shows there is currently a wind powered EV on the road.

At this point the wind power only adds ten percent to its range, but the tech is new, crude, and fertile for development and refinement.

It's real, and it's here now.

I read what else I could find about it. I have to say, I couldn't figure out exactly why it is suppose to work. The closest explanation I could find, is someone said it "proved our theory". which doesn't tell me what the theory is.

I mean I know they say a turbine charges the battery.

One possibility, is the design with the turbine somehow reduces air turbulence. Or maybe it has something to do with Bernoulli's principle.

I'll wait for some outside entity to test it. Maybe it doesn't work.

It does not matter where the resistance is. One of the issues on aerodynamics is the underside of the car. Things hanging down can cause as much drag as a roof rack or side view mirrors. No matter where you put it the drag will happen.
