The illustrations above show a windmill-powered electric car. The top illustration shows the car with it's windmill retracted. This is what the car looks like when it's being driven. The illustration underneath shows the same car with it's windmill extended. This is what the car looks like when it is parked. Whenever the car is parked, the windmill can be extended so the car's batteries can be recharged with wind power. Power produced by the car's windmill is stored in the car's batteries. This type of car does not require any fuel, does not pollute the air, and does not contribute to global warming.
