Turbine comparison

​

While HAWTs are the most efficient type of turbines in open areas where flows are constant and laminar, they underperform in turbulent flows such as those typically encountered in the built environment. They also require a yawing mechanism to face the wind direction. In the built environment where wind flows vary a lot, a great amount of power is lost as they constantly need to adjust to the change in wind direction.

​

Darrieus-type turbines do not self-start. They require electrical start-up by turning temporarily their generator into a motor, thereby consuming energy to reach their operational rotational speed so that they can start producing power. In some instances, their energy usage can be higher than their production.

​

Yawing and start-up mechanisms increase the risk of failure and require additional maintenance.

Capabilities

 

  • Provides viable commercial volume power to grid-connected and off-grid energy users.

 

  • Is a clean and reliable source of energy that provides customers with certainty of energy costs.

 

  • Produces energy even in turbulent flows and low wind velocity sites, allowing for massive distributed power uptake.

 

  • Smoothes out costly power spikes associated with traditional energy supply by electricity grids.

 

  • Combines with solar and energy storage to provide hybrid power solutions.

 

  • Has application in marine energy and offshore wind energy extraction.

 

Discriminators

 

  • Patented and innovative technology that is uniquely suited to the built environment where it operates efficiently, safely, silently and blends in architecturally.

 

  • Provides compelling economics by being the lowest cost commercial quality turbine and providing customers with up to 335 per cent returns.

 

  • Turbines are mass-produced, modular and stackable units, allowing for minimal installation costs, limited downtime and quick and easy replacement if a unit fails.

 

  • Turbines can be ducted which increases power output by up to three times.

 

  • Turbines potentially produces up to 9 times more power than a solar installation of the same footprint.​
