ABSTRACT:

Electrical energy plays a vital role in our day today life. A

nd now it has been seems to be oneo

f the basic needs of the human beings. As, the populatio

n keeps on increasing the demand on the

electrical energy is also increasing. The resources fort

he electrical energy generation are also depleting at a faster rate. So now it has been essential go for an alternative method to generate electricity. Under this situation, we have done a project in which we can generate electricity by walking on the staircase. This paper deals about this method of generation of electricity. It is a non- conventional method of electricity generation. Non-conventional energy system is very essential at this time to our nation.

1. INTRODUCTION:

The weight which acts on the staircase

is used to generate electrical energy. The mechanical energy (weight) is converted into electrical energy using drive mechanism such as rack and pinion assemble & chain drive mechanism.

When a person claims the

staircase, a force has been acted on the step which has been placed at a certain angle of inclination. Due to the force the steps moves downward and so the rack will moves down and so the pinion gear which has been connected to the rack will tends to rotate. This rotational speed has been increased using chain and sprocket drive.

This rotational movement of the shaft

is coupled to a D.C. generator with the help of Spur Gear. The D.C generator used in this project is Permanent Magnet D.C generator. Fly wheels is also used in order to have

continuous power generation.

The Output of the generator is 12

Volts. This 12 Volt is stored in a lead acid battery (7 Amp-Hour). The battery is connected to the inverter which is used to convert the D.C to A.C volts. By increasing the capacity of battery and inverter circuit, the power rating is increased. This power can be used to run a bulb or fan.

2. NEED FOR NON-CONVENTIONAL ENERGY:

In a survey it has been stated that by 2020 fuel

scarcity will be maximum and the countries

like India may not have the chance to use

petroleum product. India has only about 25

years of oil reserves and 75 100 years of coal

reserves. So we have to reduce the usage of

coal to generate electricity instead of that we

have to use other resources to generate

electricity. Since electrical energy is

considered to be the one of the fundamental

need for the survival of mankind. Since

increase in the standard of living is directly

proportional to energy consumption. The price

of the oil, gases is also increasing and also it

causes serious environmental problems. so we

have to go for the non conventional method of

energy generation.

3. HARDWARE REQUIREMENTS:

Staircase arrangement

Rack and pinion

Chain sprocket arrangement

Spur gear

D.C generator (Permanent magnet)

Battery (Lead-acid battery)

Inverter and its controls

Light load

4.1. Rack and Pinion Arrangement: Rack & pinion arrangement is used inorder t

o convert the linear motion of the inclined step to rotational movement of theshaft. The rack is

connected to the inclined step and pinion gear is connected to the shaft

through keys. Pinion the circular gear and rackis the linear gear.

Both this are made up of castiron.

4.2. Chain Sprocket Mechanisms: Chain sprocket mechanism is used to increase the speed of rotation of the shafts.

5. PROPOSED MODEL

6. OUTPUT VOTAGE WITH RESPECT

TO WEIGHT OF THE HUMAN:

7. CONCLUSION:

From the above result we can

conclude that, as the weight of the individual

who uses the staircase increases the output

voltage also increases. And also the power

generation will be higher if the staircase has

been used for more number of times. So if this

type of staircase is placed in the crowded

region more power generation will be there.

And also the power

region more power generation will be there.
