US Patent 9446670 Energy generating system

An energy generating system may comprise a plurality of airfoils rotating about an axis that is perpendicular to an axis along a flow of air, the airfoils being staggered in multiple rows perpendicular to the axis along the flow of air and across a top surface of a vehicle, and a plurality of generators each comprising a rotor and a stator, each stator configured to channel the airflow along the leading edge of the airfoils, each rotor connected to each of the plurality of airfoils, the rotor configured to generate energy by rotating around the axis, the energy converted into electrical power.
