VAWT Advantages:

VAWTs offer a number of advantages over traditional horizontal-axis wind turbines (HAWTs):

  • Being omni-directional, some forms do not need to track the wind. 
  • VAWTs generally function better than HAWTs in turbulent and gusty winds. HAWTs cannot efficiently harvest such winds, which also cause accelerated fatigue.
  • the gearbox of a VAWT takes much less fatigue than that of a HAWT.
  • In VAWTs, gearbox replacement and maintenance are simpler and more efficient, as the gearbox is accessible at ground level, so that that no cranes or other large equipment are needed on-site. This reduces costs and impact on the environment. Motor and gearbox failures generally are significant considerations in the operation and maintenance of HAWTs both on and offshore.

    VAWT Advantages

    These turbines have fewer parts than those that orient the rotary mechanism and blades horizontally. That means fewer components to wear out and break down. Also, the supporting strength of the tower doesn’t need to be as much, because the gearbox and generator are near the ground. Parts for controlling pitch and yaw aren’t needed either.

    The turbine doesn’t have to be facing the right wind direction either. In a vertical system, air flowing from any direction or speed can rotate the blades. Therefore, the system can be used to generate power in gusty winds and when they’re blowing steadily.

    VAWTs are:

    • Cheaper to produce than horizontal axis turbines.
    • More easily installed compared to other wind turbine types.
    • Transportable from one location to another.
    • Equipped with low-speed blades, lessening the risk to people and birds.
    • Function in extreme weather, with variable winds and even mountain conditions.
    • Permissible where taller structures are prohibited.
    • Quieter to operate, so they don’t disturb people in residential neighborhoods.

    Disadvantages of VAWTs

    Not all of the blades produce torque at the same time, which limits the efficiency of vertical systems in producing energy. Other blades are simply pushed along. There is also more drag on the blades when they rotate. Although a turbine can work in gusty winds, that is not always the case; the low starting torque and dynamic stability problems can limit functionality in conditions the turbine wasn’t specifically designed for.

    Since the wind turbines are lower to the ground, they do not harness the higher wind speeds often found at higher levels. If installers prefer to erect the structure on a tower, these are more difficult to install in such a way. However, it is more practical to install a vertical system on a level base, such as the ground or the top of a building.

    Vibration can be an issue at times, and even increase the noise produced by the turbine. Air flow at ground level can increase turbulence, thereby increasing vibration. This can wear out the bearing. At times, this can result in more maintenance and therefore more costs associated with it. In earlier models, blades were prone to bending and cracking, causing the turbine to fail. Small units atop buildings or other structures may be subject to jostling forces, which add lateral stress that warrants ongoing maintenance and the use of stronger, more sturdy materials.

How can we eliminate or control the vibrations that is produced?

Is there a way to apply brakes or any other mechanisms to prevent destruction of turbine in the strong wind? Or the shape of airfoil is preventing high speeds? Please advise.

With this design you could use the coils as a very effective break. You need to connect the 3 phases coming out of the generator to a rotary selector position switch that would normally forward them to the stabilizer, controller etc. behind, but when changed, it would shorten them altogether.

I'm curious how much power this produces because I wanted to make some Vertical windmills at my house to constantly power some appliances and perhaps find a way to push that in conjunction with solar panels to overpower my household. This design looks nice so I figured I would ask what its capabilities are.
