3. Need of projects
 Increasing energy demand
 encouragement cogeneration and reduce bourdon on
conventional energy sources.
 mechanical moving object for the power generation
and utilization to production of energy.
 Non-Renewable energy sources expired 2-4 decades.
 Focus on reducing wastage of energy in various forms
and production of the free energy.
 Cheap source of energy producing by rotating part of
the moving object.

4. Introduction
 The moving object which produce a mechanical
energy by utilization of the rotation of the moving
object generate an electrical energy.
 The rotational moving object the emf will induced in
the coil and generate the electricity.

5. Block Diagram

6. Working principal
 Faradays first law :when the conductor cuts the rate of
change of flux an emf will induced in it.
 Faradays second law: the magnitude of induced in a
coil is directly proportional to rate of change flux
linkage.

7. Actual implementation

8. Component
 Acrylic sheet
 Magnet
 Copper coil
 Rectifier
 Rechargeable battery

9. Advantages
 Simple construction
 Light weight
 Reliable
 Less maintenance
