Air powered electrical generator (APEG) motive parts are mounted on an axle carrying bilateral air turbines and two intermediate rotor subassemblies. Circular rotor blade plates have scalene triangularly shaped cavities with long leading edge sides receiving compressed air flow, short trailing edge sides and an open peripheral air portal. Adjacently mounted blades are offset such that one air portal then another air portal is presented to compressed air flow from nozzles during rotation. Each turbine shroud has a manifold feeding compressed air to the nozzle, as a venturi, due alternating presented air portals. Each rotor carries permanent magnets on its radially outboard segments. Bilateral stationary stators are transversely fixedly mounted outboard of the rotating rotor subassemblies. Electrical outputs carry power from the stators when the rotor subassemblies rotate.

The present invention provides a vortex dynamic power generation structure that consists of the cylindrical cavity, the driving mechanism and the power generating mechanism. The vertical cylindrical cavity has plural fluid inlets at side and the fluid outlet at the center of the top surface. The driving mechanism consists of the permeable blade set and the rotating axis is installed at the center of the cylindrical cavity. The character of present invention is as the following. The external fluid flows into the cylindrical cavity tangentially to form the vortex, and the vortex continue accelerates automatically as the tornado does. The vortex thrusts the driving mechanism to rotate, and the permeable blades allow the vortex maintain its spiral route. The permeable blades feedback rotating energy to further accelerate the vortex. The center part of the vortex flows along the axis of the cylindrical cavity to the outlet and exits. The power generating mechanism is connected to and driven by the driving mechanism to generate electricity.

Disclosed is a method of adaptively adjusting lift and drag on an airfoil-shaped sail. The method includes: (1) mounting at least one airfoil-shaped sail body having an airfoil-shaped cross section; (2) defining a Y-shaped air jet channel in the airfoil-shaped sail body; (3) arranging a flow regulating gate in the Y-shaped air jet channel; (4) adjusting the flow regulating gate to automatically adjust the gate opening extent and the cross section opening or closing extent in response to an oncoming flow with a varying direction and speed, to regulate the airflow within the air jet channel and accordingly change the angle of attack, so that the lift and drag on the sail body can be automatically adjusted as the wind speed changes. Further disclosed are an airfoil-shaped sail implementing the above method as well as a vertical-axis wind turbine employing the airfoil-shaped sail.
