Wind Turbine Plans
Are you looking for a good wind turbine plans? Building a wind turbine requires a thorough understanding of how wind turbines work. Wind can be defined as a movement of air between high and low pressure regions in the environment, caused due to the irregular heating of the earth by the sun. When the air above the earth surface is heated it gets light and rises up creating a low pressure zone. Finally the air surrounding the higher pressure zones flows through the low pressure area, creating wind.
The exhaustion of fossil fuel resources combined with mounting pollution affecting the environment has turned the focus on using alternative energy resources. Especially the resources which do not harm the atmosphere, wind energy is reliable and economical resource which provides a considerably large portion of power requirement around the world. Wind turbines are a practical way to convert kinetic energy into either mechanical or electrical energy. They can be used for different applications like pumping water and generating electricity. The wind turbines are being used for centuries now; many parts of the world still use them for pumping water and grinding grain.
The most efficient way of converting wind energy into mechanical or electrical energy is through wind turbines that operate as a lifting device. Wind turbines are generally classified into two categories:
- Horizontal Axis Wind Turbines (HAWT)
- Vertical Axis Wind Turbines (VAWT)
Horizontal Axis Wind Turbines capture kinetic energy with a propeller type rotor, their rotational axis is parallel to the direction of wind. These propeller type turbines are more popular as compared to Vertical Axis Wind Turbines.
Vertical Axis Wind Turbines use curved or straight bladed rotors with rotating axis perpendicular to the wind direction. These turbines can capture wind from any direction. Vertical Axis Wind Turbines are again classified according the mechanical and aerodynamic characteristics, lifting surfaces, or the movement of the blades along a path in a horizontal plane.
Today there are four types of VAWT:
- Giromill
- Savonius
- Musgrove
- Darrieus
Wind Turbines are used for many reasons be it economical, environment or even philosophical. In order to use wind successfully an individual must have a good site and the aptitude to select the right machine. A wind turbine of any type and size is not cheap. It represents an investment in the future provided the right efforts are made in the build-up. The knowledge that a person is saving money or even earning it is more than sufficient reward for using wind energy. By generating clean electrical energy, the environment of the surrounding become effectively less polluted and at the long run helps in rejuvenating it.
