In the present scenario energy crisis is the biggest problem faced by mankind.

India is a country, which suffers a lot due to the lack of sufficient power generation.

In India, Conventional fossil fuels are the main sources for power generation, but there is a fear that

they will get exhausted eventually by the next few decades.

Therefore, This new system is invented to produce electricity without using any commercial fossil

fuels. This latest technology uses the potential energy of automobiles for production of power.

INTRODUCTION

ENVIRONMENTAL IMPACT OF CONVENTIONAL METHODS OF ENERGY PRODUCTION.

The increase in usage of fossil fuels increases causes

depletion of resources.

Increase in ATMOSPHERIC POLLUTION.

Emission of harmful and carcinogenic substances into the

atmosphere

Methods of mining of fossil fuels can be highly

destructive.

Not sustainable etc.

WHY DO WE NEED THIS PROJECT..???

This project puts a relief to the growing consumer demands.

This project enables low budget power production.

Energy can be produced throughout the year.

Simple Construction.

No Manual labour required during generation.

Maintenance is easy.

Pollution free power generation.

Does not consume any non-renewable resources.

CONSRUCTIONAL DETAILS

The most important parts used are

Rack and Pinion.

Spur Gear.

Springs

Ball Bearings.

Electrical Generator (or) Dynamo.

RACK AND PINION

A rack and pinion is a type of linear actuator that

comprises a pair of gears which convert rotational motion

into linear motion or vice versa.

In this setup, The rack is welded to the base of a dome

shaped plate which represents the speed Breaker.

The pinion is mounted on a platform. The ball bearing

provides easy and efficient motion of the pinion wheel.

SPUR GEAR

Spur gears or straight-cut gears are the simplest type

of gear.

Here, spur gear is responsible for converting the small

movement of pinion into larger motion (by choosing

effective gear ratio)

The spur gear is placed on a parallel shaft which is

connected to the dynamo.

Correct meshing of gears is necessary for effective

power production.

SPRINGS

A spring plays the most important role in this

experimental arrangement.

It is the compression of springs that enables the motion

of the rack and pinion.

The springs are placed in between the two steel

platforms.

BEARINGS

A bearing is a machine element, which

supports another machine element. It permits

a relative motion between the contact

surfaces, while carrying the load.

Bearings are placed between each gears and

shaft in order to reduce friction and provide

easy motion

ELECTRICAL GENERATOR (OR) DYNAMO

The dynamo uses rotating coils of wire and magnetic

fields to convert mechanical rotation into a pulsing direct

electric current through Faraday's law.

The dynamo is directly connected to the spur gear with

the help of a small shaft.

The Dynamo is responsible for converting the mechanical

energy produced in gear drives into electrical energy.

This electrical energy can be given to a battery and

stored for future use

CONSTRUCTION

WORKING PRINCIPLE

It utilizes both mechanical and electrical techniques for the power generation and its

storage.

It consists of a dome shape which represents the speed breaker

Whenever the vehicle passes over the dome, the speed breaker moves downwards

due to the action of the mass of the vehicle on the springs.

Since the rack is welded on to the base of the dome, the compression of the spring

causes linear motion of the rack and pinion and arrangement.

Small motion in the larger pinion can cause high rotation in the smaller pinion.

Since the dynamo and gear are connected, the rotation of gear becomes the source of

mechanical energy for the dynamo.

The dynamo converts the mechanical energy into electrical energy.

This output energy can be amplified and stored using electrical devices.

RESULTS AND ANALYSIS

It has been found that the energy produced by the speed breaker depends on two main

factors

1. Mass of the vehicle

2. Speed of the vehicle

VARIATION OF CURRENT PRODUCED DUE TO CHANGE IN MASS

VARIATION OF VOLTAGE PRODUCED DUE TO CHANGE IN SPEED

DISADVANTAGES

We have to check mechanism from time to time.

It can get rusted in rainy season.

It will not work with light weight vehicle

Spring tension might reduce over time and hence it needs replacement after a

while.

APPLICATIONS

This power can be used in the following:

Street Lights.

Road Signals.

Sign boards on the roads.

Lighting Of the bus stops.

Lighting of the check post on the highways etc.

CONCLUSION

Now, vehicular traffic in big cities is more, causing a problem to human being. But this

vehicular traffic can also be utilized for power generation by this unique technique.

As it does not utilize any external source, and traffic will never be reduced, these power humps

are more reliable, and have more life than any other power source.

If it is placed in heavy traffic roads, the weight and kinetic energy of the vehicles can be used

to produce mechanical power in shafts and this mechanical power is once again converted into

electrical energy.
