Vertical axis Wind turbine (VAWT)

The images here are provided for a point of reference only and represent a vertical axis wind turbine design that is similar in nature. The proprietary design of the actual Comerton wind turbine is currently under development and our engineering team will be releasing it soon.The Comerton Wind Turbine will include of a number of proprietary design enhancements, improvements and the inclusion of the ABT Technology.

VAWT's vs. traditional horizontal-axis wind turbines (HAWTs):

  • ABTThey are omni-directional and do not need to track the wind. This means they don't require a complex mechanism and motors to yaw the rotor and pitch the blades.
  • ABTAbility to take advantage of turbulent and gusty winds. Such winds are not harvested by HAWTs, and in fact cause accelerated fatigue for HAWTs.
  • ABTThe gearbox of a VAWT takes much less fatigue than that of a HAWT. Should it be required, replacement is less costly and simpler, as the gearbox is easily accessible at ground level. This means that a crane or other large equipment is not needed at the site, reducing cost and impact on the environment. Motor and gearbox failures generally increase the operational and maintenance costs of HAWT wind farms both on and offshore.
  • ABTSome VAWTs can use a screw pile foundation, allowing a huge reduction in the carbon cost of an installation as well as a reduction in road transport of concrete during installation. They can be fully recycled at the end of their life.
  • ABTCan be grouped more closely in wind farms, increasing the generated power per unit of land area.
  • ABTCan be installed on a wind farm below the existing HAWTs; this will improve the efficiency (power output) of the existing farm.
  • ABTResearch at Caltech has also shown that a carefully designed wind farm using VAWTs can have an output power ten times that of a HAWT wind farm of the same size.

Clean, Green Energy

Wind turbines provide a clean energy source, emitting no greenhouse gases and no waste product. Over 1,500 tons of carbon dioxide per year can be eliminated by using a one megawatt turbine instead of one megawatt of energy from a fossil fuel. Being environmentally friendly and green is a large advantage of wind turbines.

Why Our VAWT Design is Better:

  • ABTEasier to Maintain & Service.
  • ABTNot Harmful to Birds & Bats
  • ABTLonger Warranty.
  • ABTLess Ice and Debris build up
  • ABTSignificant Reduction in Vibration
  • ABTLess Heat Build Up
  • ABTLighter Components
  • ABTProduces Power both at Low & High Wind Speeds
  • ABTAbility to Control Wind Source Speed
  • ABTCan be combined with Solar
  • ABTLower Manufacturing Costs
  • ABTLess Downtime
  • ABTCustomized Mobile App

VAWT Advantages

Vertical-axis wind turbines (VAWTs) have the main rotor shaft arranged vertically. One advantage of this arrangement is that the turbine does not need to be pointed into the wind to be effective, which is an advantage on a site where the wind direction is highly variable.

Wind turbines are generally inexpensive. They will produce electricity at between two and six cents per kilowatt hour, which is one of the lowest-priced renewable energy sources. And as technology needed for wind turbines continues to improve, the prices will decrease as well.

In addition, there is no competitive market for wind energy, as it does not cost money to get ahold of wind.

 The main cost of wind turbines are the installation process. The average cost is between $48,000 and $65,000 to install. However, the energy harvested from the turbine will offset the installation cost, as well as provide virtually free energy for years after.
