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