PRESENTATION OUTLINE

INTRODUCTION LITERATURE REVIEW METHODOLOGY PROJECT PLANNING AND COST RESULT AND DISCUSSION CONCLUSION AND RECOMMENDATION

INTRODUCTION Energy Harvesting Door is a

device created to harvest and store electrical energy from the movement of opening and closing of a door

PROJECT BACKGROUND

The pinion, which is attached to hollow bar, will rotate the magnet. This will generate

electromagnetic flux.

Electromagnetic is induced and AC current is produced through the wires.

In the circuit, the AC current will be stored in the capacitor.

AC current is converted to DC current by the rectifier, resulting in the current flow in the circuit

to lighten up the LED.

PROBLEM STATEMENT

1. Non–renewable energy is energy which is taken from the sources that are available on the earth in limited quantity and eventually come to extinction.

2. From the movement of the door (open/close), this potential energy can be utilized and transform into other form of energy.

OBJECTIVES

To design a low cost working prototype that can

harvest the energy from the movement of the

door.

LITERATURE REVIEW / DATA GATHERING

Electromagnetic induction is a process where a conductor placed

in a changing magnetic field causes the production of a voltage

across the conductor and this is in turn, causes an electrical

current. Michael Faraday is generally credited with the discovery of

induction in 1831. [1]

Generally, the Energy Harvesting Door consists of several main components which play imperative role in generating electrical energy :

1) Door The door is the main component which the process takes place

in it. The movement of the door will initiate the process of

generating electricity.

2) Conversion of Energy Energy is conserved and converted throughout the process. Potential energy Kinetic energy Electrical energy

3) Electricity Electricity generated is distributed for domestic usage

especially for electrical appliances purpose. In the prototype, electricity generated due to current induced

from the movement of magnet in coil
