Vertical-axis wind machines are among the oldest forms of wind technology, with documented examples dating back more than a thousand years. Modern VAWT development accelerated in the 20th century with the work of Georges Darrieus, yet challenges around efficiency, self-starting and control have remained.
Maarten, Eric and Rob believed that modern engineering, combined with a novel approach to blade control and turbine architecture, could address those longstanding challenges. That belief became Flag Turbines.
Their ambition was simple: to develop a new form of wind energy that could operate efficiently at relatively low height, respond to wind from any direction and generate power close to where it is consumed. It also had to be scalable, straightforward to install and maintain, and suitable for locations ranging from farms and businesses to remote and off-grid communities.
Sustainability had to extend beyond the electricity being generated. The turbine was therefore designed around the principles of using fewer materials, avoiding complex composite materials wherever possible, maximizing recyclability and minimizing its environmental impact throughout its life.
Low rotational speed, limited visual impact and quiet operation were also fundamental to the design, allowing the turbine to work alongside people, wildlife and the surrounding environment.
To turn that vision into reality, the team formed BLOwN and brought together engineers and scientists to develop a new approach to wind generation. Years of design, modelling, prototyping and testing have resulted in Flag Turbines’ cycloidal vertical axis wind turbine technology, combining automatic variable blade control with a fundamentally different approach to capturing energy from the wind.
The objective remains the same as it was at the beginning: to make clean, locally generated energy available in more places, to more people.
