In this system we are generating electrical
power as non-conventional method by simply
walking or running on the foot step. Non-
conventional energy system is very
essential at this time to our nation.
Nonconventional energy using foot step is
converting mechanical energy into the electrical
RACK AND PINION
COMPONENTS OF FOOT STEP
A lever is a machine consisting of a
beam or rigid rod pivoted at a fixed
It is the simplest machine which is
basically used to reduce the human
2.RACK AND PINION
Rack and pinion is used to
convert linear motion to
In foot step energy generator
generally pinion consists of 12
teeth and pitch circle diameter
is 1 inch.
Rack is 45.2 cm long and
consists of 50 teeth.
Shaft is a mechanical component for
transmitting torque and rotation.
In foot step energy generator pinion and
ratchet gear are mounted on the same
The purpose of ball bearing
is to reduce rotational
friction and support radial
and axial loads.
The diameter of inner ring is
A ratchet gear a mechanical device
that allows continuous linear or rotary
motion in only one direction while
preventing motion in the opposite
A flywheel is a rotating
mechanical device that is
used to store rotational
In foot step energy generator
flywheel is used to drive the
DC generator which produces
the electrical energy.
It is an electrical device which is used
to convert mechanical energy into
30 volt DC generator has been used in
foot step energy generator.
Mild steel is a type of steel that contains small
amount of carbon and other elements. It is
softer and more easily shaped than higher
carbon steels. It also bends a long way
instead of breaking because it is ductile.
Mild steel is a carbon steel which contains
• The complete diagram of the foot step power generation is
given below. The pushing power is converted into electrical
energy by proper driving arrangement. The rack & pinion,
spring arrangement is fixed at the inclined step. The spring
is used to return the inclined step in same position by
releasing the load.
• The generator is used here, is permanent magnet D.C
Stepper Motor. The generated voltage is 12 Volt D.C. This
voltage is further amplified using DC-DC convertor and is
stored to the Lead-acid 12 Volt battery.
The battery is connected to the inverter.
This inverter is used to convert the 12 Volt
D.C to the 230 Volt A.C.
This 230 Volt A.C voltage is used to activate
the light, fan and etc. By increasing the
capacity of battery and inverter circuit, the
power rating is increased. This
arrangement is fitted in shopping complex,
college and wherever the large people
walking on the foot steps simultaneously.
•Reliable, Economical, Eco-Friendly.
•No need of fuel input.
•This is a non-conventional system.
•Battery is used to store the
Power generation using foot step can be
used in most of the places such as:-
• Cinema theatres,
• Shopping complex
• Railway stations
• Bus stand, etc.
•Foot step energy generator is suitable for
small amount of power generation such
as charging cell phones, door lightnining
and hoarding street lamps.
•For efficient working it should be used
where people walk frequently such as
malls, foot paths, railway stations, etc.
