SUMMARY
In this paper our effective approach is to harness electrical energy from the highway by using of vertical axis wind turbine. The smart windmill consists of a stationary shaft which is mounted on the ball bearing on the top and bottom end of the shaft The curvy darrieus blades are connected to the two ends of bearing which is able to rotate on its own axis. The dynamo is connected to the either upper part or lower part of the wind turbine which works on Flemings left hand rule of Electromagnetic induction. In highway both at day as well as at night time vehicles will be moving at very high speed. By this method the overall cost per unit of energy produces is less than the cost of new coal, natural gas and its installation. So the implementation can be made easier than any other methods.
