Abstract
Abstract A fluid flow accelerator structure which is substantially the shape of an interior section of a hollow toroid of general arbitrary cross-section in both vertical and horizontal planes, meaning that in both a vertical and horizontal plane a cross-section may be non-circular, and circumventing an axis central to said toroid, providing fluid flow channel means about the exterior periphery of said structure, and wherein fluid impact impellers are mounted within said fluid flow accelerator channel means in regions of optimum flow velocity for optimum energy recovery, and said fluid flow accelerator is further provided with partial shroud shell means on parts of its periphery and therewith completely circumventing projected actuator discs of said impact impellers, about an axis substantially perpendicular to said actuator discs, in complement with said peripheral channel means. The invention is contemplated for use in conjunction with electric generators or power generating systems in general capable of utilizing power output from said impact impellers operating on said fluid flow accelerator structure. The omnidirectional fluid flow accelerator referenced in the former application above shall hence forth be referred to as a Toroidal Accelerator Rotor Platform or TARP in acronym form.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
167 words
A power generating device comprising; fluid impact impellers for converting fluid flow energy into mechanical energy; a fluid flow accelerator structure being substantially the shape of an interior section of a hollow toroid of general arbitrary cross-section in both vertical and horizontal planes; meaning that in both a vertical and horizontal plane the cross-section may be other than circular, circumventing an axis central to said toroid, providing open fluid flow channel means and defining augmented flow velocity regions about the exterior periphery of said structure, and wherein rotatable fluid impact impellers are mounted in the augmented flow velocity regions within said peripheral channel means for maximum energy recovery; partial shroud shell means mounted to the fluid flow accelerator on part of its periphery to structurally complete circumventing each projected actuator disc of said impact impellers in complement with said peripheral channel means and about an axis substantially perpendicular to said projected actuator discs whereby additional energy output by said impact impellers via larger fluid streamtube capture occurs.
