CR VAWT wind turbines reimagined - manufacturing

Manufacturing advantages:

Establishing a manufacturing facility in Darwin has many advantages including:

1.      creating local jobs and training;

2.      providing a cost effective process for local manufacture of main components and assembly of the products;

3.      ease of shipping for national and international markets; and

4.      protecting valuable intellectual property for competitive advantage around the world.

The semi submersible base of the arrays are critical to longevity. As such we have chosen concrete caissons as the prefered material, such as advocated by Construction Technologies & Engineering Inc.  https://www.slipform.us/applications/offshore/

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 manufactured using our patented mechanised pultrusion process (below right). This provides industry leading quality control which is less labour intensive and produces light weight blades that are efficient and save on material costs.

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.

By manufacturing the columns on-site using our own patented system, we bring down transport and inventory costs.

In relation to HAWTs, components including large mechanical parts such as pitch and yaw systems provide additional costs, complication, and maintenance and reliability concerns. Such mechanical parts are not required on the CR VAWTs due to its omnidirectional capabilities.
