The technology behind the VertAx wind turbine design is a culmination of contributions from universities and privately funded research carried out by the founders over many years. It includes a combination of older technology re-visited with new design knowledge as well as substantial innovation, incorporating state of the art materials and modern manufacturing techniques. Much of the technology has been taken from other industrial sectors and then improved upon and adapted for the application of an off-shore wind turbine generator. This approach means that there are few aspects pertaining to the individual components that remain unproven, albeit in other industrial applications.

The primary goal driving the technology development was to provide a stepped reduction in the cost of electrical power generation from off-shore wind. By designing a machine that is modular and has few moving parts, VertAx Wind Ltd and its technology partners believe they now have the makings of a design that will enable them to achieve their stated objectives.
