Wind-powered Electric Cars
Windmill-powered electric cars
Electric cars with retractable windmills could recharge themselves.
An electric car could produce it's own electric power if it were equipped with a retractable windmill. The windmill would normally be stored inside the trunk of the car,so the car would have a conventional appearance, it would look like an ordinary car. When the car's batteries were running low on power, you would have to park the car, and extend the windmill. The windmill would extend automatically, when you pushed a button on the dashboard. When the windmill has extended to full height above the car, the windmill blades would automatically unfold. The car must remain parked like this for several hours, or several days, to fully recharge the car's batteries. Whenever the wind blows, the windmill blades spin, and the windmill produces electricity. The electricity produced by the windmill is stored in the car's batteries. When the car's batteries are fully charged, the windmill can be put back into storage. To put the windmill into storage. you push a button on the dashboard, and the windmill blades automatically fold up, then the entire windmill retracts and goes into storage in the car's trunk. Finally the trunk lid automatically closes. After the windmill is stored, the car is ready to drive.
There is no guarantee that the wind will blow every day, so this car may not replace a gasoline-powered car, in most commuting applications. Instead, it is intended for people who don't drive very often, for example, a retired man or woman who no longer has to drive to work every day. After retirement, the need to drive is usually reduced, and a retired person may drive only two or three times per week, for example, to go shopping or to visit friends and relatives. The windmill-powered car may also have practical applications in third-world countries where fuel is scarce or expensive. Windmill-powered electric cars do not require fuel, they do not pollute the air, and they do not contribute to global warming.
