FOOT STEP ELECTRICITY GENERATION SYSTEM

Synopsis

POWER CRISIS is being one of the major topics to be discussed. The

possible solution for this is to provide considerable amount of poer using

adaptable reneable resources. !mong these resources" human population is the

onl# abundant and perennial resource that has not been utili$ed. If a suitable

method is available" e%pected amount of poer can be tapped out from this

resource. e have presented the idea to utili$e human locomotion poer to

produce electricit# and also e have designed a method named POWER

PRO&'CI() P*!T+OR," a large scale project that consists of number of similar

mechanical setups under a special flooring s#stem. When people al- over the

platform" electricit# is generated in this s#stem utili$ing the pressure due to eight

of the person al-ing on the platform and stored using dr# batteries. This method

ill have an efficient outcome if installed in countries here population is more.

!s per this strateg#" this method is ell suited for our countr# and a large poer

can be tapped out The objective of this project is to generate the electric poer

through the fabrication of foot step arrangement. (o da#s poer demand is

increased" so this project is used to generate the electrical poer in order to

compensate the electric poer demand. The hole human/ bio0energ# being

asted if can be made possible for utili$ation it ill be great indentation and crod

energ# frames ill be ver# useful energ# in croded countries.

In this project the conversion of the force energ# in to electrical energ#. The

control mechanism carries the pie$o electric sensor" !.C ripples neutrali$er"

unidirectional current controller and 123" 1.4!mp lead acid &C rechargeable

batter# and an inverter is used to drive !C/&C loads. The batter# is connected to

the inverter. This inverter is used to convert the 12 volt &.C to 245 volt !.C. this

245 volt !.C voltage is used to activate the loads. We are using conventional

batter# charging unit also for giving suppl# to circuitr#.

INTRODUCTION

Proposal for the utili$ation of aste energ# of foot poer ith human

locomotion is ver# much relevant and important for highl# populated countries li-e

India and China here mobilit# of its masses ill turn into boon in generating

electricit# from its footsteps.

In India" places li-e roads" raila# stations" bus stands" are all over croded

and millions of people move round the cloc-. !s a result large amount of poer can be obtained ith the use of this promising technolog#.

This process involves number of simple setup that are installed under the

al-ing platform. When people al- on this platform their bod# eight

compresses the setup hich rotates a d#namo or San#o coil and current produced

is stored in dr# batter#. To reduce the e%ternal compression" a responsive sub0

flooring s#stem is installed. !nd hile the poer producing platform is over

croded ith moving population" energ# is produced at larger levels. Greater

movement o peop!e "i!! #enerate more ener#y.

This hole human energ# being asted if can be made possible for utili$ation

it ill be great invention and poer producing platform ill be ver# useful energ#

sources in croded countries.

PRINCIPLE$

This setup or-s on the principle of converting the linear motion due to

pressure of foot steps into rotar# motion. This rotar# motion is utili$ed to rotate a

poer generating device6d#namo or San#o coil7. The poer generated is stored

using dr# batter#. The amount of rotation depends upon the eight of the personal-ing over the platform and the tension of the spring used. &epending upon the

poer generator used" the poer output can be increased.

! responsive flooring s#stem made up of bloc-s that depress slightl# under the

force of human steps ould be installed. The flooring s#stem depresses to a little

e%tent as people al- over them hich in turn depresses the mechanical setup

installed immediatel# beneath it. This simple mechanical setup consists of a

compressible top platform and a immovable bottom platform. Other components of

this s#stem are" four primar# springs" a lever assembl#" a shaft fitted ith to free

heel bearings" a large pulle#" a smaller pulle#" poer generator6d#namo or san#o

coil7" and a brea- arrangement. The compression of the top la#er is provided b#

the springs installed in four corners. Then it consists of a lever assembl#" to

freeheel bearings fitted to a shaft" a large pulle# attached to the shaft and a

smaller pulle# connected ith the large pulle#. The small pulle# is coupled ith

the d#namo hich rotates hen the small pulle# is rotated. There is a secondar#

spring arrangement and a brea- s#stem to provide additional rotations to the small

pulle#.

%OR&ING8

When people al- on the floor" the floor press on the mechanical setup. The

setup depresses due to the spring action and pulls the lever assembl# hich rotates

one of the freeheel bearing fitted to the shaft. The shaft then rotates the large

pulle# hich is connected to the smaller pulle# through a 30belt. This smaller

pulle# acts as a reducer hich provides more rotations corresponding to one

rotation of the large pulle#. This smaller pulle# coupled ith the d#namo 6or san#o

coil7" a device that converts the energ# of motion into electric current and poer is

obtained.

This process depends on to factors" primar# spring tension and t#pe of

generator used. The primar# spring tension is determined b# 'a!'(!atin# t)e

avera#e "ei#)t over a !o'omotive area. To get more poer output" t#pe of

generator is considered as the main factor. When the pressure is applied through a

foot step" ninet#0five percent of the pressure applied is converted into energ# in

this method.

A*ERAGE %EIG+T OF LOCOMOTI*E AREA$

This parameter is used to determining the primar# spring tension of the setup.

+or e%ample" if the project is installed in a higher secondar# school" the spring

tension must be able to ithstand the loads of different students almost in same age

group" staffs etc. This gives the average eight of 9: to ;5 -g. So the spring

tension must ithstand : -g less and more to average eight. The hole eight

ill not be acting on the spring tension alone but on the hinges of the flooring

s#stem also. This parameter also has an influence over the hinge arrangement of

flooring s#stem.

uired compression to eight group of ;5-g to ?5-g and considerable

compression to eight group belo ;5-g and ould able to ithstand the eight

group of above ?5-g. This average eight varies from place to place.

PO%ER GENERATOR$

We have used to 93 !C d#namo as the poer generator for this project. The

main advantage this provided as the small rated speed re>uired to produce poer of 9 atts and a current of 1! in each of the d#namo.

The total current accounted for the to d#namo as 2! and this as rectified and

stored in a 9W dr# batter#. This batter# ill get charged full# ithin 4 hours hen

charged using poer producing platform. This time ill be considerabl# reduced

hen e use number of d#namos to charge a single 9W dr# batter#. ! single

poer producing platform can accommodate @ d#namos and hen the batter# is

charged using all the current from these @ d#namos" time ta-en to charge

completel# reduces belo 2 hours. The batter# can be used to suppl# the

re>uirement as from then and there or it can be ported to place of re>uirement. +or e%ample if this project is used in raila# platform" all the batteries poered b#

several setups in the da#time can be used to suppl# the a# lights across the

platform during the night time.

Instead of d#namo san#o coils are used to produce poer. San#o coil is also

similar to d#namo. The d#namo accommodates thic- copper coils hereas san#o

coil uses ver# thin aluminium coils. Single san#o coil produces 2@ volts hereas

a d#namo can produce onl# 93 or 123.

This increases the efficienc# of the project to greater e%tent hence e prefer san#ocoil to d#namo. ,ore than one batter# can be charged using one setup hen san#o

coils are installed in it. !part from this" e can also use generators having less

rated speed to increase the efficienc# of the project.

SECONDARY SPRING$


5/9

There is a secondar# spring arrangement hich consists of a spring and a brea-

s#stem. This arrangement is used to produce additional rotation time to the

generator. When the setup is compressed continuousl#" this spring gets ound on

the shaft slol#. The reverse rotation of the shaft under the tension of the spring is

prevented b# the brea- s#stem and second freeheel bearing that is fitted to the

shaft until the spring attains its ma%imum tension. uirement to solve poer crisis.

!s ever# bloc- over the setup is connected to one another using hinge

arrangement" the compression ill not be felt as the eight of the person al-ing

over that ill be distributed. uired to compress the setup ill

be conve#ed as the persons eight acts on the particular setup onl#

&epending upon the average eight over a locomotive area" the strength and

number of hinges are used.

+or the area here average eight is more" the numbers of the hinges are

increased. This along ith the primar# spring provides the re>uired compression

for the setup.

This hinge arrangement distributes the eight of the person and prevents them

from feeling the compression.
