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, a phenomenon known as Time-Dependant-Energy-Transfer. The PowerCone draws on these principles, directing wind from the central root section to outer radial spans of the blade and channeling it smoothly onto its surface. Further, its presence causes a local area of high pressure, nudging wind to bend radially outwards upwind of the rotor.
As a maple seed falls to the ground, it moves through the air with a pattern of least resistance, following its coning angle. This allows the maple seed to deal with turbulent air by interacting with the flow over a longer time-span, at some acute angle to the incoming flow. The PowerCone’s blades follow the seed’s elegant cues: relying on the same principles of Time-Dependant-Energy-Transfer, absorbing gusts and reducing loads. This geometry also allows the PowerCone to increase the effective flow velocity on the blade by wrapping around the wind turbine’s blades — increasing torque, decreasing cut-in speeds, and increasing the turbine’s capacity factor.
