ABSTRACT:POWER CRISIS is being one of the major topics to be discussed. The possible solution for this is to provide considerable amount of power using adaptable renewable resources. Among these resources, human population is the only abundant and perennial resource that has not been utilized. If a suitable method is available, expected amount of power can be tapped out from this resource.we have presented the idea to utilize human locomotion power to produce electricity and also we have designed a method named FOOT STEP POWER GENERATION, a large scale project that consists of number of similar mechanical setups under a special flooring system. When people walk over the platform, electricity is generated in this system utilizing the pressure due to weight of the person walking on the platform and stored using dry batteries.This method will have an efficient outcome if installed in countries where population is more. By using such principle the energy can be utilized in the whole area where the mechanical energy is Being converted to electrical energy CONTENTS Page NoABSTRACT 3contents 4CHAPTER : 1.

CHAPTER 1:1. INTRODUCTION

Man has needed and used energy at an increasing rate for his sustenance and wellbeingever since he came onthe eartha few million years ago.Primitive man required energyprimarily in the form of food.He derived this by eatingplants oranimals, 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 workfor 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 forsailing ships and for driving windmills, and the force of falling water to turn waterwheels.Till this time, itwould not be wrong to saythat the sun was supplyingall the energy needs of man either directly or indirectly and that man was using only renewable sources of energy.

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 iscomposed of standard parts that areeasily 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 electricitygeneration.

1.1. Seminar overview: 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 andmillions 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 crowded countries. 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 farmswill be useful for nearby applications.

CHAPTER 3: HARDWARE DESCRIPTION 3.1 Foot step arrangement:WORKING OF FOOT STEP GENERATOR:Step1: when force is applied on the plate by virtue on stamping on the plate the force spring gets compressedStep2: the rack here moves vertically down Step3: The pinion meshed with the rack gear results in circular motion of the pinion gearStep4: for one full compression the pinion Moves 1semicircleStep5: when the force applied on the plate released the pinion reverses and moves another semi-circleStep6: the generator attached to the pinion hence results in the sinusoidal waveform (for single Generator)3.2 Rack And Pinion and chain sprocket arrangement: Arack and pinionis a type oflinear actuatorthat comprises a pair ofgearswhich convert rotational motion into linear motion. The circularpinionengages teeth on a linear "gear" bartherack.Rotationalmotion applied to the pinion will cause the rack to move to the side, up to the limit of its travel.

CHAIN SPROCKET:

Asprocketis a profiledwheelwith teeth that meshes with achain,trackor other perforated or indented material. It is distinguished from agearin that sprockets are never meshed together directly, and differs from apulleyin that sprockets have teeth and pulleys are smooth. Here 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.

3.3. PMDC Generator

Working:The commutator rotates with the loop of wire just as the slip rings do with the rotor of an AC generator. Each half of the commutator ring is called a commutator segment and is insulated from the other half. Each end of the rotating loop of wire is connected to a commutator segment. Two carbon brushes connected to the outside circuit rest against the rotating commutator. One brush conducts the current out of the generator, and the other brush feeds it in. The commutator is designed so that, no matter how the current in the loop alternates, the commutator segment containing the outward-going current is always against the "out" brush at the proper time. The armature in a large DC generator has many coils of wire and commutator segments. Because of the commutator, engineers have found it necessary to have the armature serve as the rotor(the rotating part of an apparatus) and the field structure as the stator (a stationary portion enclosing rotating parts)

3.4. Battery RECHARGEBLE BATTERIES: Arechargeablebatteryorstorage batteryis a group of one or moreelectrochemical cells. They are known assecondary cellsbecause theirelectrochemical reactionsare electrically reversible. Rechargeable batteries come in many different shapes and sizes, ranging anything from abutton cellto megawatt systems connected tostabilizean electrical distribution network. Several different combinations of chemicals are commonly used, including:lead-acid,nickel cadmium(NiCad),nickel metal hydride(Nigh),lithium ion(Li-ion), andlithium ion polymer(Li-ion polymer).

3.5. InverterAninverteris an electrical device that convertsdirect current(DC) toalternating current(AC); the converted AC can be at any required voltage and frequency with the use of appropriatetransformers, switching, and control circuits. Solid-state inverters have no moving parts and are used in a wide range of applications, from smallswitching power suppliesin computers, to largeelectric utilityhigh-voltage direct currentapplications that transport bulk power. Inverters are commonly used to supply AC power from DC sources such assolar panelsorbatteries. Fig 2.26: Inverter There are two main types of inverter. The output of amodified sine waveinverter is similar to asquare waveoutput except that the output goes to zero volts for a time before switching positive or negative. It is simple and low cost (~$0.10USD/Watt) and is compatible with most electronic devices, except for sensitive or specialized equipment, for example certainlaser printers. Apure sine waveinverter produces a nearly perfect sine wave output (
