"For electric vehicles to go mainstream, charging will need to be widely accessible and convenient.
For now, most electric car owners plug in their vehicles at home and charge overnight"

"Wind turbines work on a simple principle: instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity."

Instead of the ram air system forcing air into the motor, the air would be used to spin turbines to recharge the batteries. Every time the automobile is in foward motion, the turbines would be spinning and recharging the batteries. If the batteries reach full charge, the turbines would stop spinning.
The faster the road speed, the faster the turbines would potentially spin. Slow road speed would be the equivalent of low wind speed, while higher road speeds would equate to higher wind speeds.
"Wind turbines generate electricity by using wind power to drive an electrical generator.
When the wind passes over the blades, it exerts a turning force. The rotating blades make a shaft turn inside the nacelle, which goes into a gearbox.
Next, the gearbox speeds up the rotation to an appropriate level for the generator, which uses magnetic fields to convert the rotational energy into electricity."

"How fast do wind turbines spin? The speed of the wind turbine depends on how fast the wind is blowing"
