PowerConeTM

A turbine retrofit that unlocks wind power’s true potential  

 

You can’t create wind, but you can make the most of what’s blowing

The PowerCone is a turbine retrofit that channels incoming wind onto the blades to address root leakage. The result is not just more power, but power from a place where no bigger blade or smarter software can find it.

Natural Flow

At the core of wind turbines is a problem that robs them of power. Root leakage draws potential power away from the blades and generates turbulence. 

Root leakage is essentially a problem of airflow. To solve it, we turned to two of the natural world’s most effective ways of moving through fluids: the kingfisher and the maple seed. 

 
 

Cutting Through

The kingfisher owes its reputation to how its beak allows it to plunge through the water with barely a ripple — in effect moving the fluid around itself at a precise rate. The PowerCone draws on these principles, directing wind from the root to outer spans of the blade and channeling it smoothly onto its surface.

Unlocking Time

As a maple seed falls to the ground, it moves through the air with a pattern of least resistance. The PowerCone's blades follow the seed's elegant cues: relying on the same principles of time-dependant energy efficiency, it absorbs gusts and channels wind along its blades — increasing torque, decreasing cut-in speeds, and increasing the turbine's capacity factor.

The power of Evolved Design

 

Most turbine retrofits only play at the margins. The PowerCone cuts to the heart of the issue in every way, redistributing wind to enhance existing turbines.

The PowerCone attaches directly to the hub of the turbine and co-rotates with the rotor, helping it to capture more of the wind that’s already blowing.

More Power

The PowerCone doesn’t just capture more of the available wind — it lowers cut-in speeds, increases torque and ultimately makes the turbine more effective and efficient.

Reduced Loads

The PowerCone smooths incoming gusts and aligns the airflow with the turbine blades. This reduces turbulence, vibration, and the associated loads on the turbine blades and drivetrain.

 

Less Noise

The PowerCone’s efficiency helps your turbine reach rated power sooner, reducing both blade pitch angle and sound output.
