ABSTRACT
• In this project we are generating electrical power as non-conventional
method by simply walking or running on the foot step
• Non-conventional energy using foot step is converting mechanical energy
into the electrical energy.
• This project using simple drive mechanism such as rack and pinion assemble
and chain drive mechanism.
• For this project the conversion of the force energy in to electrical energy.
The control mechanism carries the rack & pinion, D.C generator, battery
and inverter control.
• The D.C generator used in this project is Permanent Magnet D.C generator.
• The Generator is coupled to the Ply wheel Shaft with the help of Spur Gear
Mechanism.
• The Output of the generator is 12 Volts. This 12 Volt is stored in a 7 Amp-
Hour Battery.
• The battery type is Lead-Acid battery
• The battery is connected to the inverter which is used to convert the D.C 12
• Volt to the 230 Volt A.C.
INTRODUCTION
MOTIVATION:
Man has needed and used energy at an increasing rate for his sustenance and well being ever since he came on the earth a few million years ago. Primitive man required energy primarily in the form of food. He derived this by eating plants or animals, which he hunted.
With the passage of time, man started to cultivate land for agriculture. He added a new dimension to the use of energy by domesticating and training animals to work for him. With further demand for energy, man began to use the wind for sailing ships and for driving windmills, and the force of falling water to turn water for sailing ships and for driving windmills, and the force of falling water to turn water wheels. Till this time, it would not be wrong to say that the sun was supplying all the energy needs of man either directly or indirectly and that man was using only renewable sources of energy.
EXISTNG SYSTEM
Other people have developed piezo-electric (mechanical-to-electrical) surfaces in
the past, but the Crowd Farm has the potential to redefine urban space by adding a
sense of fluidity and encouraging people to activate spaces with their movement.
The Crowd Farm floor is composed of standard parts that are easily replicated but
it is expensive to produce at this stage. This technology would facilitate the future
creation of new urban landscapes athletic fields with a spectator area, music halls,
theatres, nightclubs and a large gathering space for rallies, demonstrations and
celebrations, railway stations, bus stands, subways, airports etc. like capable of
harnessing human locomotion for electricity generation.
NEED FOR THE SYSTEM:
Proposal for the utilization of waste energy of foot power with
human locomotion is very much relevant and important for highly populated
countries like India and China where the roads, railway stations, bus stands,
temples, etc. are all over crowded and millions of people move around the clock.
This whole human/bioenergy being wasted if can be made possible for utilization
it will be great invention and crowd energy farms will be very useful energy
sources in crowdedcountries. Walking across a "Crowd Farm," floor, then,will be
a fun for idle people who can improve their health by exercising in such farms
with earning. The electrical energy generated at such farms will be useful for near
by applications.
WORKING PRINCIPLE:
• The complete diagram of the foot step power generation is given above.
• Only one step is inclined in certain small angle which is used to generate the power.
• 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 pinion shaft is connected to the supported by end bearings as shown in fig.
• The larger sprocket also coupled with the pinion shaft, so that it is running the same speed of pinion.
• The larger sprocket is coupled to the small cycle sprocket with the help of chain (cycle).
• This larger sprocket is used to transfer the rotation force to the smaller sprocket.
• The smaller sprocket is running same direction for the forward and reverse direction of rotational movement of the larger sprocket.
• This action locks like a cycle pedaling action. The fly wheel and gear wheel is also coupled to the smaller sprocket shaft.
