Electricity Generation Using a Wind Turbine

Introduction

Wind turbines are machines built for generation of electricity . The electric power is generated by harnessing the wind speed to drive the shaft that connects to the gears assembled to amplify the amount of energy produced . Aside from wind power , other forces , like gravity and thermal energy , also affect the rotation of the blades , which in

turn affect the electricity generation process . This research is aimed at creating a simple wind turbine that is capable of generating electricity . The process will be explained using the principles found in physics such as the law of gravity , electromagnetism , thermodynamics and momentum

Materials and Method

The wind turbine setup was created using these devices : hub , three fan blades , metal box , two sets of gears , copper wire , a permanent magnet and volt meter , two rods of different sizes and couple heat sinks . These devices were then assembled to a working wind turbine . First , the blades were at an angle of 20 degrees . Then the gears were connected to the metal hub . The gears were then connected to a permanent magnet that was used to generate the electricity . The magnet was coiled with 80 turns of copper wire (about ? inch ) for generation of power . It was then spooled to a steel block which helped increase the voltage just like a transformer . Greased bushing was also set up between the two gears and the hub . The perforated cylindrical block was placed on both rods to serve as a heat sink . The second rod was bent at the tip to change cyclic motion to vertical motion to the magnet . Finally , the wind turbine was mounted on a 10 feet tall support above ground level and was observed

Discussion

The wind turbine was observed to see how it can generate electricity or if it can . As the wind blew on the blades , they turned along with the shaft . The shaft was connected to the gears that were also connected to the permanent magnet . When the magnet moved , the volt meter needle deflected which meant it detected electric power from the wind turbine The wind turbine was successfully set up and generated electricity

The process of converting wind energy into electric energy can be explained using some of the principles in physics : law of gravity electricity and magnetism , thermodynamics , and momentum . While the whole setup depends on wind movements , other types of forces also affect the generation of electricity such as gravity and friction

Newton 's first law of motion states that an object at rest will remain at rest while an object in motion will remain in motion ' This is also called the Law of Inertia or the resistance of an object to change its state of motion . Mass , being the property of matter , is used to measure the amount of inertia . This...
