A New Wind Turbine Architecture Designed to Reduce the Cost of Energy
DWTurbine is a patented bladeless wind turbine platform with the potential to improve efficiency, reduce complexity and lower LCOE in utility-scale wind.
Why A New Wind Turbine Architecture?
-
Wind is a $175B+ annual market
-
Turbine design hasn’t fundamentally changed in decades
-
Cost, complexity and installation constraints remain
-
DW Turbine addresses these structurally

A Shift In The Industry
Expected 30% CAPEX reduction
Lower O&M / higher reliability
TRL 2.5 to TRL 3 in progress
Creating $4.6m additional value for a machine* that costs $3m
* based on a 4MW onshore turbine
ONSHORE
Our Solution
Concealed Blades, Superior Performance
Structural Integrity
Neutral drag coefficient minimises the effect of wind speed on the mast bending load (Steady state condition)
Superior Energy Harvesting
Energy harvesting not limited to Betz limit. Limit is governed by the lift force that can be generated without flow detachment
Simple Design and Minimal Cyclic Forces
Multi-rotor designs are simple to implement allowing for a four-rotor harvester
Low Cost and Easy Transportation
Common low-cost material usage, common construction and transport suitability
Where are we today?
Technology Readiness Level: 2.5
Seeking strategic and financial partners
We are currently raising seed capital to advance the DW Turbine technology to TRL 5.
