Savonius Wind Turbine At A Glance

Wind power is one of the best options to our current power crisis. One method to harness the winds power is through a device called wind generator. A typical horizontal axis windmill demands a place for at least an acre and blowing wind speed of not less than eleven miles per hour; a prerequisite most area doesn’t usually meet. Even the device itself can be costly since conventional wind generator demands tall towers to operate. One of the best alternatives to typical wind generator is the savonius wind generator.

The savonius wind generator was invented by a Finnish engineer named Sigurd J. Savonius in the 1920′s. During that time, horizontal axis windmills were already widely used. But early conventional windmill designs were quite sophisticated and expensive to arrange and maintain. The savonius wind generator became an ideal option. The system was adapted for applications such as water pumping and grain grinding.

The savonius design has several advantages over convention horizontal axis wind generator. The design patented by Sigurd J. Savonius was one of the few vertical axis windmill; also known as VAWT’s. Due to its vertical axis, the system can operate even at varying wind direction; a feature you won’t obtain from conventional horizontal axis generators. Because the savonius design is effective even with low blowing wind situation, the system doesn’t require a tower or other costly structure to hold it in place which greatly reduces its initial setup cost. And since the system is close to the ground, maintenance may be accomplished effortlessly.

Because of the ease of the design, any DIY and alternative power lover can create their own savonius wind generator at home. The material frequently used to produce the scoops is made up of a single oil barrel cut lengthwise. The two halves are then joined on one side to create an “S” shape when viewed from the top. Because the design uses scoops instead of rotor blades, the system can operate silently without waking up the neighbors. And due to the lack of long rotor blades, it is harmless for birds that would pass near the system.

However, as a result of lack of rotor blades of the savonius wind generator is also its disadvantage. The scoop system it uses to harness the winds power has only half the efficiency of conventional generator resulting to much less energy generation. Although the system is short on efficiency, it still provides some fascinating feature such as the low profile style making it durable even with very strong winds. Above all, it allows you to enjoy the benefits of the winds free power all at a much less cost.
