ENERGY SPEED BUMPyou hit it, you lit it

Energy speed bump is an energy harvestingsystem that generates electricity fromkinetic energy. It resembles a speed bumpand is able to generate electrical energywhen vehicles pass over it, without the needto reduce their speed.

Scope

A portable electricity-generating speed bumpthat does not reduce the speed of vehicles

when they pass over it

Novelty

Introduction

to be placed beneath the road function with the force exerted onto it amount of electricity generated depends

on mass and speed electricity generated will then be directed

to street lamps or even signboard It can also be used at the door mate, grand

entrance, stairs and toll plaza.

Significance of the project To reduce the burden of the government Reduce environmental pollution Enhance the current safety level of roads

As an alternative source of energy which iscleaner and greener to generate electricity

The motor shaft attached

to the free wheel is also

rotated.

Fly wheel increase the

rotations of motor shaft

Motor shaft transfers the

rotation force to the gears

attach to the dynamo

Inside the dynamo , inducedcurrent is produced by

Results and discussion

Relationship between mass

of the load and the voltageproduced.

To study this relationship, a load ofmass 5, 10, 15, 20 and 25 kg is raisedat height 10 cm and released on thebump. The reading of the voltage istaken.

Relationship between speed

and the voltage produced.To study this relationship, a load ofmass 5 kg is raised at a height of 5cm and then released on the bump.The reading of the voltage is taken.The experiment is repeated by usingheight 10, 15, 20 and 25 cm.Velocity, v, of the load is measuredby using the formula

gh = v2

where g = 10 ms-2 , h = height.
