Turbine Design

Combining the Darrieus and Savonius vertical axis wind turbines constitutes for an effective, efficient and aesthetically pleasing model, capable of capturing urban and rural winds.

Our Model

The drag force of the overlapping (S-type) Savonius rotors provides an efficient self-start as low as 3 m/s, which is then enhanced by the natural lift force and momentum of the outer Darrieus rotors. 

Benefits of Darrieus-Savonius design

  • Captures omnidirectional winds
  • Begins operations at lower wind speeds
  • Operates at lower RPM
  • Minimal vibration levels
  • Minimal noise levels
  • Three-blade Darrieus design for maximum efficiency
  • Two-Blade Savonius design allows for a quicker self-start and effectiveness in low winds
  • Simple maintenance – no frictional drums or pads to wear out rotor bearings
  • Smaller operating footprint
  • Less Intrusive than other Vertical Axis Wind Turbines (VAWT) and Horizontal Axis Wind Turbines (HAWT)
  • Easy to install
  • Integration onto buildings or any viable location.
  • Anodised Aluminium for strength and longevity
  • A thoroughly engineered and tested design
  • A unique and attractive design
  • Reliable and consistent performance

*Solar panel can be installed with solo turbines upon request

 

Why small-scale?

The small-scale turbine market is forecast to grow.

Renewable power generation is crucial to clean growth, having undertaken thorough research into the market area, there exists a need to provide an efficient and cost-effective small-scale turbine for urban and rural application. Through smart and intelligent engineering, the barriers and deficiencies that have been associated with small scale wind turbines have been minimalised.

Our vertical axis turbines capture the turbulent winds often associated with cities in an effective, silent and safe manner whilst also providing sufficient power.


What is a Vertical Axis Wind Turbine?

A Vertical axis Wind Turbine’s (VAWT) rotating blades sit perpendicular to the wind direction. This enables them to capture wind from any direction and can run at lower wind speeds. A Horizontal axis Wind Turbine’s (HAWT) blades are parallel to the wind.
