Wind is a very popular source of alternative energy. Unlike solar, a properly setup wind turbine will generate electricity throughout the day, day and night for years to come. You can save at least 80% of your energy bill with a wind power system. But if you are a victim of the myths created around generating residential wind power, you might end up losing money instead of saving. 5 Biggest myths associated with residential wind power are listed below. Before you start your project check whether you are a victim of any of these myths. Otherwise it will be too late.
Helical wind turbine is a type of vertical axis wind turbines (VAWT). Main feature of this type is its helically shaped wind blades which can turn the turbine even in small winds. Its ability to run even in small winds, and its ability to place relatively in a lower position, makes it the ideal solution for residential wind power. When placed on a roof top helical turbine can produce nice amount of electricity. Helical wind turbines are gaining in popularity worldwide. Read More… (Click on the Title)
The Darrieus Turbine dates back to 1927, when French aeronautical engineer Georges Jean Marie Darrieus patented this innovative turbine design. The Darrieus Wind Turbine resembles a gigantic eggbeater and has two main advantages. The first main advantage is that the equipment including the gear box and the generator can be placed close to the ground. The second advantage to this type of wind turbine is that you don't need a new mechanism to turn the rotor against the wind
Savonius is a type of Vertical Axis Wind Turbine (VAWT). This is characterized by its “S” Shaped rotor. Rotor will be pushed by the wind and will make the turbine to spin. Main drawback when compared with the Darrieus type of wind turbine is, in Savonius maximum speed it can achieve is limited by the speed of the wind making it to produce less electricity. But this is less complicated design and well suited for domestic use.
