a car that runs on a battery that never needs to get charged

A dynamo produces electricity when it is turned and batteries gives energy to motors to turn a wheel.while the wheel is turning we can use this energy to turn the dynamo and produce electricity that charges the battery at the same time the car is moving.Of course we will need a huge battery but by nano technology we can minimize the size by using nano-batteries.
