ABSTRACTThe Gravitational force or Body weight is used to

generate electricity with the help of Rack & Pinion, Gears,

Chain drive, Sprocket, PMC Generator, Battery andinverter!

By si"ply stepping on the "echanis" the electricity is

generated without any production of har"ful gases or any

other #y product! $t is a #io%friendly "echanis" whichreduces the usage of conventional energy resources



e"and of power supply in

$ndia•The energy policy of $ndia is largely

defined #y the countrys

#urgeoning energy deficit and

increased focus ondeveloping alternative sources of

energy, particularly

nuclear, solar and wind energy!

•'#out ()* of $ndias energy

generation capacity is fro" fossil

fuels, with coal accounting for +)* of

$ndias total energy consu"ption

followed #y crude oil and natural

gas at -* and .* respectively!



$ndia is largely dependent on fossil fuel i"ports to "eet its

energy de"ands / #y )0), $ndias dependence on energyi"ports is e1pected to e1ceed 20* of the countrys total energy

consu"ption!

$n ))3%4), the country i"ported 423!. "illion tonnes of

crude oil which a"ounts to -)* of its do"estic crude oilconsu"ption and 04* of the countrys total i"ports are oil

i"ports!

The growth of electricity generation in $ndia has #een

hindered #y do"estic coal shortages and as a conse5uence,

$ndias coal i"ports for electricity generation increased #y 4-*

already e1ist #y pie7o%electric effect !

6or pie7o%electric%effect output is very s"all and"ore nu"#er of crystal is re5uired to increase to get

sufficient output !

But in our "ethod electrical power is produced with

no e1tra energy or attention is re5uired, only hu"an

#ody weight due to gravitational force is used here as

the fuel!



$n this we are generating electrical power as non%

conventional "ethod #y si"ply walking or running on thefoot step!

8on%conventional energy using foot step is converting

"echanical energy into electrical energy #y

9FARADAY’S LAW OF ELECTROMAGNETICINDUCTION”!

6oot step generator can #e used everywhere, where

hu"an traffic is very "uch like shopping "alls , cine"a

hall , general "arkets, railway station , #us stand, su# way, park and any housing co"ple1 entrance , etc!



:orking Principle

:hen force is applied on the plate #y virtue on sta"ping

on the plate the force spring gets co"pressed

The rack here "oves vertically down

The pinion "eshed with the rack gear results in circular

"otion of the pinion gear

6or one full co"pression the pinion Moves 4se"icircle

:hen the force applied on the plate released the pinionreverses and "oves another se"i%circle

The generator attached to the pinion hence results in the

sinusoidal wavefor" ;for single Generator<

6ro" the a#ove ta#le we can infer that the voltage

produced #y the PMC generator varies according to the

weight of the person stepping on it! So voltage is directly

proportional to the weight of the person! More the weight

of the person "ore the a"ount of voltage produced! Morevoltage can #e produce #y increasing the trans"ission

ratio and gear ratio!



ConclusionThe proKect )FOOT STEP POWER GENERATION

FOR RURAL ENERGY APPLICATION TO RUN

A*C* AND D*C* LOADS” is successfully tested and

i"ple"ented which is the #est econo"ical, afforda#le

energy solution to co""on people! This can #e used for

"any applications in rural areas where power availa#ility

is less or totally a#sence! 's $ndia is a developing country

where energy "anage"ent is a #ig challenge for huge

population! By using this proKect we can drive #oth 'C as

well as !C loads according to the force!
