Abstract

A fluid driven electrical generation system with most of the electrical generation components in an inner hollow of a housing that is driven to rotate by trapper structures that trap energy from the fluid.

Claims (5)

1. A device for generating electrical power from fluid flow energy comprising:

a housing that rotates, said housing having an interior hollow;

trappers on the housing that rotate the housing by capturing fluid flow energy,

an electrical generator contained in the interior hollow of the housing and configured

with rotating rotor within the interior hollow that rotates with rotation of the housing, wherein the housing rotates about an axis and a stationary stator is disposed not on the axis and the rotor is mounted on the axis to rotate in a spinning motion adjacent to the stationary stator, further wherein the rotor and the stator are contained within a stationary generator casing with the stator attached to the casing, further wherein the rotor is attached to a rotating shaft and the stator is attached to a stationary shaft, and the rotating and stationary shafts are constructed such that one shaft is hollow with the other shaft passing through its interior.
