Wind Oscillator for Power Generation


Detailed Technology Description

A wind-powered electricity generator has been developed that utilizes wings to efficiently capture the energy of low or high speed winds. The wings are positioned horizontally and oscillate around a central axis. This wind-powered generator provides numerous advantages in manufacturing, operation and efficiency in comparison to the wind, turbine generators presently favored for electrical generation.



Government and industry have aggressively pushed the development of wind turbine technology. Horizontal-axis wind turbines (HAWT) have been widely adopted for commercial power generation, while there are numerous issues that decrease the cost-efficiency of medium and large size HAWT. Because aerodynamic force is proportional to the wing area of a blade, it is difficult to maximize the effective wing area of a rotating blade as the size of the blade increases. The turbine blades must be long and slender, particularly near their tips to reduce centrifugal force and maintain structural integrity. This limits the effective wing area near the tip of the blade, where a considerable amount of aerodynamic torque is normally generated. Installation of long slender blades on a large-sized HAWT is particularly difficult, and requires special equipment that may not be easily operated in certain terrain. Contamination from dead bugs and birds near the leading edges of blades can reduce their aerodynamic efficiency by 50%, and cleaning the blades is not an easy task.
