The windmill will generate power as the car moves and air blows into it. This power will be used to charge the car’s battery. Can you improve car battery efficiency by attaching the windmill to the top of your electric car?

We see that the windmill is attached on top of the car. This means that when the car will move then the windmill will get winds so its blades can move. When these blades will move, it will produce electrical energy. ... So it can help in charging battery of car.

Hope it's helps you :)

Well, this is indeed a correct query. Windmill will have some weight and provide drag on car which will increase overall weight of car and thus car will feel more resistance (drag) from air to move freely

Hope its helpful
