ABSTRACT:
A method and device for collecting energy from wind includes an airfoil having an outer surface defining a leading edge, a central section of greatest breadth adjacent to which a Bernoulli effect reduced pressure region results as an air flow passes over the airfoil from the leading edge to a trailing edge, an air passage contained within the outer surface, and a plurality of edge nozzles penetrating the outer surface within the section of greatest breadth. The edge nozzles each have an outlet orifice oriented toward the trailing edge and an inlet orifice feeding into the air passage and being positioned to communicate between the air passage and the Bernoulli effect reduced pressure region. The airfoil is positioned in the wind with the leading edge facing substantially into the wind and with the wind passing over the edge nozzles. An airflow-driven turbine capable of converting an airflow into rotational mechanical energy is also provided, the turbine being in airflow communication with the air passage. A flow of air is drawn through the airflow-driven turbine, thence through the air passage and out through the edge nozzles into the Bernoulli effect reduced pressure region created as the wind passes over the edge nozzles. The flow of air through the airflow-driven turbine drives the turbine and converts the flow of air into rotational mechanical energy.
