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

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

By opening and closing the door, the rack will rotate the pinion. 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.

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. 

 To design a low cost working prototype that can harvest the energy from the movement of the door.

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 [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
