Introduction

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.

we have presented the idea to utilize human

locomotion power to produce electricity and also we

have designed a method named POWER PRODUCING

PLATFORM, a large scale project that consists of

number of similar mechanical setups under a special

flooring system.

Description

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. We have discussed the

various applications and further extension also. So this project is

implemented to all road , the power generation is very high. The

initial cost of this arrangement is high.

Working Principle

The complete diagram of the foot step power generation is given

below. 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 supporter by

end bearings .

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.

PRINCIPLE:

This setup works on the principle of converting the linear

motion due to pressure of foot steps into rotary motion. This

rotary motion is utilized to rotate a power generating device

(dynamo or Sanyo coil).

The power generated is stored using dry battery. The

amount of rotation depends upon the weight of the person

walking over the platform and the tension of the spring used.

Depending upon the power generator used, the power

output can be increased.

WORKING:

When people walk on the floor, the floor press on the

mechanical setup. The setup depresses due to the spring

action and pulls the lever assembly which rotates one of the

freewheel bearing fitted to the shaft.

The shaft then rotates the large pulley which is connected

to the smaller pulley through a V-belt. This smaller pulley acts

as a reducer which provides more rotations corresponding to

one rotation of the large pulley. This smaller pulley coupled

with the dynamo (or sanyo coil), a device that converts the

energy of motion into electric current and power is obtained.

RESISTOR is a heat-dissipating element and in the electronic

circuits it is mostly used for either controlling the current in the

circuit or developing a voltage drop across it, which could be

utilized for many applications.

DC MOTOR is a mechanically commutated electric motor

powered from direct current(DC). The stator is stationary in

space by definition and therefore so is its current.

CAPACITORS

The fundamental relation for the

capacitance between two flat platesseparated by a dielectric material is given by:-

C=0.08854KA/D

Where: -C= capacitance in pf.

K= dielectric constant

A=Area per plate in square cm.D=Distance between two plates in cm

BATTERY is a device that converts chemical energy directly to

electrical energy It consists of a number of voltaic cells; each voltaic

cell consists of two half-cells connected in series by a conductive

electrolyte containing anions and cations.

CHAIN is a series of connected links which are typically made

of metal. A chain may consist of two or more links. Chains have

a surprising number of parts. The roller turns freely on the

bushing, which is attached on each end to the inner plate.

SPROCKET:

A sprocket or sprocket-wheel is a profiled wheel with

teeth, cogs, or even sprockets that mesh with a chain,

trackor other perforated or indented material. The name

'sprocket' applies generally to any wheel upon which are

radial projections that engage a chain passing over it. It is

distinguished from a gear in that sprockets are never

meshed together directly, and differs from a pulleyin that

sprockets have teeth and pulleys are smooth.

POWER INVERTER, or INVERTER, is an electrical power converter that

canghes direct current(DC) to alternating current(AC);the converted AC

can be at any required voltage and frequency with the use of

appropriate transformers, switching, and control circuits.
