Reinventing
Small Wind Energy
The QW-DAWT is a counter-rotating, diffuser-augmented wind turbine that generates up to 6x more power than conventional systems of the same rotor size.
Small Wind Has Been
Underperforming for Decades
Despite growing demand for distributed renewable energy, small wind turbines have remained fundamentally unchanged. The physics of conventional horizontal-axis designs impose hard limits on power extraction at small scales.
Low Power Density
Conventional small turbines produce only 9.1W at 5 m/s with a 700mm rotor — insufficient for meaningful applications.
High Cost Per Watt
Small wind systems cost $5.00–$8.00/W, making them 3–5x more expensive than residential solar per watt installed.
Poor Low-Wind Performance
Most small turbines require 3.5+ m/s to start generating, missing the majority of available wind hours in urban environments.

Three Multiplicative
Innovations
Each innovation independently boosts performance. Combined, they multiply: 3 × 2 × 1.3 ≈ 7.8x theoretical maximum.
Diffuser Augmentation
Hourglass-shaped diffuser captures wind from an area 4x larger than the rotor, accelerating flow to 1.6x at the throat.
Counter-Rotating Rotors
Dual 5+7 blade rotors spinning in opposite directions double the relative RPM seen by the generator, recovering wake energy.
Optimized Aerodynamics
Hybrid S1223/SG6043/SD7037 airfoils with Gurney flaps, winglets, and vortex generators achieve a Cp of 0.47.
