Simply the best in class, designed by experts.


Barely audible above ambient wind noise.


Blades are encapsulated by the diffuser.

Additional Information

We have invested more than 4 years of product research and development, including extensive computational simulations, wind tunnel testing, and field testing. Our technology is proven and leverages over 20 years of research expertise at the University of Newcastle.

Our blades have been precision engineered from carbon fibre composites and key structural components are machined from aluminium and stainless steel. The electronics have been developed by control engineers, experienced with small-scale wind. We have carefully designed our turbine and chosen materials to result in a long operational life.

Besides our market-leading efficiency, our turbine is also features a plug-and-play electrical system for 48 VDC systems, provides improved safety and reduced noise during operation, while being compact in size to facilitate retrofit on existing towers.
