The need for electrical energy nowadays is high. As technology becomes
advanced in certain areas, the ability to produce power has had to keep pace with the
increasing of demands. There is a tremendous amount of free energy in the air or
wind which is available for energy conversion. The use of wind machines to harness
the energy in the wind is not a new concept. The early machines were used for
pumping water for irrigation purposes and later developed as windmills for grinding
grain. The power in the wind at any moment is the result of a mass of air moving at
speed in a particular direction. Thus, the electric power generation technology these
days being highly develop. Since motorcycles are the main vehicle used in Malaysia,
a charging device is not available compare to cars which have a cigarette port as
charging port. Aware on free energy produced by air flow in the motorcycle exhaust,
it can be utilized to produce electricity. Having a concept of wind generator, this air
flow energy can be exploited. Therefore, the aim of this project is to generate
electricity through the conversion of wind energy to electrical energy. The methods
used are to develop a turbine for energy harvester, a DC generator for electrical
generation and an electrical circuit to boost the output produced by the generator.
The air flow is being converted into kinetic energy by the rotation of a turbine.
Attached to the turbine is the shaft and directly into the DC motor. Inside the motor,
there are two main components which are permanent magnet (stator) and winding
(rotor). The rotation of the shaft makes the rotor move and then the motor will react
as the generator. From these consequences, the generation of electricity energy can
be produced. Then, prototype being developed consists of the turbine, the casing of
the turbine, DC generator and electrical circuit. Several testing then being conducted
to see the performances and output of the prototype. By having a rechargeable
battery, electrical energy can be stored. Target of this prototype is to produce SV for
charging purpose. This electrical energy then can be used for any type of application,
such as charging the hand phone, mp3 player and even digital camera.
