Introduction

Today’s civilization will be forced to develop alternative energy source. Our current rate of fossil fuel usage will lead to energy crises in this century. In order to avoid energy crises many companies in the energy industry are inventing new ways of extracting energy from renewable resources.
Wind energy is basically the kinetic energy of moving wind. It is renewable source & thus having far reaching economic value. The use of wind energy as an auxiliary source of energy is the at most need of modern society. Wind energy is harnessed by wind turbines which may be horizontal axis turbine or vertical axis turbine.

Objective

The main objective is to develop a technique relates generally to electricity generation system along
It achieves this by using at least two races one race is stationary and the other is attached to the rotating assembly. As one of the bearing races rotates it will cause the balls to rotate. Because the balls are rolling, they have a much lower coefficient of friction than that of two surfaces sliding against each other. Fig.9. Diagram of ball bearing
Turbine: Turbine is a mechanical device that extracts energy from a fluid and converts it into work as output. A turbine is a rotor assembly, which having shaft with blades attached.
A device that can harness the wind created by running trains as they pass the turbine overhead with speed. This wind turbine power generator device is installed between railroad ties and placed half-underground so as to not interface with normal train operation. When train passes overhead, the large wind flow spins the turbine inside the device to generate electricity. When such a pressurized wind comes in contact with turbine, it need an immense requirement of new design of turbine, so as to capture maximum wind energy produced by moving train.
It’s almost using helix form of turbine blade in different ways. This turbine is coupled to shaft to transfer the motion. Fig.10. Turbine
CONCLUSION

Best way to recover waste energy by the generating power which is primary need of metro cities
By using of this technology with low initial investment we can generate more power
The technology is expected to reduce carbon emissions and also help to country to improve its economic power
Generated Power can easily transferred to local areas
It can be easily maintained by using sensors
