Savonius Wind Turbine - The Answer To Can We Make Home Wind Power Generators Efficient
There are an abundance of wind power turbine designs on the market at the present time and this document details the completely unique Savonius wind turbine. Unlike the more familiar horizontal turbine designs, the Savonius wind turbine is based on a upright architecture that relies on vertical vanes to rotate in the wind. This rotation is then exchanged through a vertical shaft to the generator for the generation of electricity. This wind turbine is the perfect selection for applications that call for minimal power, but extreme dependability The simplicity of the Savonius design makes it a popular choice among applications that require as little maintenance as possible.
In the realm of wind generated power there are a variety of designs of devices used to capture the power of the wind and convert it to electricity. Most of the designs follow the typical style of a windmill, or airplane style propeller that sits atop a tower and rotates to catch the wind. The Savonius wind turbine style is different in design because it is a vertical axis wind turbine (VAWT). This means that the real portion of the turbine that spins looks more like a spinning canister that fasten to a vertical shaft connected to the generator which is also mounted vertically near ground level. This vertical shaft then catches the wind, revolves the shaft to the generator to crank out the electrical current.
The initial design of this kind of turbine was finished in 1922 by Sigurd Savonius, a Finnish design engineer. This type of turbine is used often because of it's simple design and reliability. In addition, because it spins on a level axis, there is no need to have a directional apparatus to keep the unit aligned with the wind direction like other types. It can catch the wind in any direction and reacts at once to changes in wind direction. This type of turbine is considered a "drag style" turbine from an aerodynamic prospective.
It is based on the principle that because of the canisters shape, it experiences more drag when moving with the wind than against it and it takes advantage from the differential created and changes it to rotation. Because in general drag design turbines are not as efficient, it does not deliver as much power as the more conventional horizontal cousin, but can still have a wide range of applications. This design of wind turbine is used in many of the atmospheric monitoring stations around the world considering these tend to be located in isolated areas and the importance of reliability and low power consumption make the Savonius wind turbine a great choice.
They are also used on other distant locations like buoys far out in the ocean. They are also sometimes used to draw attention to advertising signs. In this use they are not used to produce any power, but have opposite sides painted contrasting colors to grab your attention as they spin. So, the Savonius home wind turbine is a very unique design that lends itself to many varied applications. Its simplicity and reliability make it the consummate choice for situations that require minimal power generation, dependable performance
