Provisional Patent Application Filed

The inventor has designed a fluid flow energy extraction system that requires no external rotor blades. The fundamental principle of the invention is to maximize the generation of high pressure potential in a passive structure. This is done through the design of a self-amplifying aerodynamic system consisting of two or more airfoils.  The inventor has developed several embodiments for this concept.

Market Applications:

• Wind Energy Systems

• Tidal Energy Systems

Features, Benefits & Advantages:

The placement of paired airfoils that take advantage of the acting aerodynamic pressures to produce a self-amplifying aerodynamic system.  The system can be implemented in wind energy extraction devices removing the need for the external rotor blades traditionally associated with wind turbines.

• No exterior moving parts in the wind energy system

• Reduces noise pollution in wind turbine systems

• Minimal environmental threat to wildlife

• Minimal building vibrations

• Can be more aesthetically integrated into buildings

Development Stage:

The initial design has been created but it has not been built and tested.
