Introduction:-Introduction:- Is anyone happy with current situation of

electricity in India??? So, this is our small step to try to improve

this situation by our project. First of all what does electricity mean to

us??? Electricity- Secondary source of energy i.e.

Converted from other sources. We need it for every small thing, still notice

it’s importance only during load sheading.

Objective:-Objective:-

In our country there is too much short fall of electricity and we try to overcome this problem by non-conventional source of electricity.

One of the non-conventional source of enegy is our project.

The objective of our project is to produce electricity by very low price.

multiplexes, malls,toll booths, signals,etc.

Basic principle:Basic principle:• Simple energy conversion from Mechanical to Electrical.• To generate electricity using the vehicle weight(potential energy) as input.• Possible using 3 different mechanisms:I. crank-shaft mechanismII. Roller mechanismIII.Rack-pinion mechanism

Why Rack-pinion Why Rack-pinion Mechanism????????Mechanism????????

Crank-shafts are required to be mounted on bearings which creates balancing problems leading to mechanical vibrations which in turn damage the bearings.

Secondly as bearings are of sliding type, any occurrence of variable load(which is bit obvious in case of vehicles!!)leads to balancing problem.

Roller mechanism has some different disadvantages .

Maintenance will be very difficult

Might cause collision.

What we did???Rack-pinion assembly gives good

mounting convenienceMaximum gear losses 3 to 5%Efficiency -95%

Initial experiments-PMDC motor as Generator

How is electricity generated????

Basic principle of generation of electricity.

What we did???

Construction of Construction of generator:generator:

Challenges we are Challenges we are faced:faced:

Selecting suitable generator

Selection of springs

Achieving proper balance of speed and torque

What we achieved??What we achieved??We LEARNT a lot.Constructed our own generator by

applying the basic principle.Although we got less electrical

output, we have successfully explained our idea of generating electricity from speed breaker.

Such speed breakers can be designed for heavy vehicles, thus increasing input torque and ultimately output of generator.

More suitable and compact mechanisms to enhance efficiency.

Future scope:Future scope:

AdvantagesAdvantages

Pollution free power generation.Simple construction , mature

technology , and easy maintenance.

No manual work necessary during generation.

Energy available all year round.

Conclusion:-Conclusion:-The existing source of energy such as

coal, oil etc., may not be adequate to meet the ever increasing. These conventional sources at energy also depilating and may be exhausted.

It is an non conventional type of producing the energy. This project is a one step to path of exploring the possibilities of energy from several non- conventional

energy sources.
