Windsurf (WS133)

Our flagship project, encompassing over ten years research & development.

The Windsurf utilises a vertical axis and blades that rapidly adapt to conditions using our pioneering algorithms created via Computational Fluid Dynamics (CFD).

The vertical axis and efficient harvesting make this a much more versatile turbine that’s fully at home in urban settings.

The modular structure sees the Windsurf classified as “mobile” and therefore can be deployed promptly without the need for planning permission.

It has minimum impact on the environment as it is capable of self-starting and is viewed by birds and wildlife as a solid object that is instinctively avoided.

The Windsurf is proving popular across a number of industries though it lends itself particularly well to Telecoms.  

Technology & Benefits

  • Conventional turbines (HAWTs) have trouble harvesting in turbulence as they are too slow to react. The Windsurf is a Vertical Axis machine (VAWTs) which performs better in turbulence as it is omnidirectional.

  • CFD facilitated the development of algorithms / look-up tables for the controller that enable the blade angle to be set based on factors including wind speed and direction (measured at the top of the turbine) as well as the position of the blade in its rotation around the central shaft. Ultimately this ensures continuously optimised efficiency.

  • The Windsurf can be fully installed, integrated, retrofitted or stand alone.

  • Using a Container based approach, a hybrid system comprising the high efficiency Windsurf WS133 turbine, PV panels, battery storage and small backup generator can be quickly and easily deployed to remote or difficult locations.

  • The relatively small footprint of the Windsurf along with its inherent ability to cope with turbulent wind conditions and reduced windspeeds means that installation in the urban area is seen as a promising opportunity for this technology class.

FAQs

  • During research phases we identified that planning permission often delays the deployment of standard turbines. We therefore designed the Windsurf to be modular and mobile to overcome this. Its modular design combined with its size and flexibility means it can be up and running in a very short time-frame with limited bureaucratic hinderance.

  • No, it is self-starting. We use a non-cogging generator which reduces resistance and permits easier starting.

  • No, the Windsurf appears as a solid object to birds. In our trials we recorded no fatalities. Also, as the Windsurf is self-starting there is no requirement for diesel powered starting equipment.

  • No. The Windsurf uses a non-cogging generator which reduces both noise and vibration.

  • Whilst a typical wind turbine would not be viable in an urban area, the Windsurf is. This is due to the Windsurfs size and efficiency even with low windspeed and turbulence.

  • Absolutely, we quickly recognised that one of the drawbacks of traditional wind turbines was their permanence. The windsurf has a modular design which means it can be disassembled relatively easily and moved.
