CR VAWT wind turbines reimagined - Manufacturing

Manufacturing advantages:

Being able to manufacture all the main components and assemble on-shore in Darwin gives a huge financial advantage to CR VAWT! We can then tow or ship these massive structures globally.

A key cost of wind turbines are  the blades which account for 25% of HAWT costs as they are very labour intensive (below left). Because of this complexity MOST HAWT blade failures can be traced back to a manufacturing error.

Our CR VAWT blades are a constant NACA0018 blade profile cross section and can be manufactured using our patented mechanised pultrusion process (below right) which provides industry leading quality control with labour and weight savings.

Gearboxes: Typically represent 13% to 15% of wind turbine costs and adds complexity and maintenance issues. The Farste Drive and CR VAWT doesn’t require any gearboxes. 

 Columns: By manufacturing the columns on-site using our own patented system, we are able minimise transport and inventory costs.

The most significant remaining components are control systems such as pitch and yaw systems which are not required in CR VAWTs.
