betz &# 39 ; s law establishes an efficiency limit of 0 . 59 for wind turbines . increasing turbine output power requires making the blades larger thereby increasing the radius of the turbine , which increases power by that factor squared , or by increasing the velocity of the air which increases the power according to that factor cubed . it would be beneficial to provide a wind turbine that overcame some of the disadvantages of prior art horizontal and vertical turbines including but not limited to , installation infrastructure , operation in non - laminar flow environments , operation over a wider range of air velocities , operation in low air velocity that defines many regions of the world and continental united states , and capable of supporting installations over a wide range of instances from discrete residential / commercial installations to large wind farms as well as providing increased output power through increased air velocities generated within the turbines .
