Abstract
Abstract A device for storage and release of energy having a body rotatably connected to a center shaft and two fins pivotably connected to the body. The pins have arms which each have an inertia block on an end of the respective arm. The arms are connected to the body by springs. A hood connected to the center shaft deflects an air stream toward the fins and the fins are pivoted rearwardly, radially displacing the inertia arms by centrifugal force. When the force of the air stream decreases, the springs urge the inertia blocks to return and stored energy is released, sustaining the rotation of the body.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
233 words
A device for storage and release of energy using centrifugal force, the device comprising: a body rotatably connected to a center shaft, a hood connected to the center shaft and extending forwardly of the body, a directional tail fin connected to the center shaft and extending rearwardly of the body, a pair of fins pivotably connected to the body, the fins being mounted diametrically opposed to one another and extending outwardly from the body, each fin being connected to an arm at approximately a right angle thereto, each arm having an end oriented toward the hood, two inertia blocks, one connected to the end of each arm, two springs, each spring connecting a respective arm to the body, wherein, an air stream directed toward the device is deflected by the hood toward the fins, the directional tail fin maintaining the body facing toward the air stream, the air stream engaging both fins and forcing the fins to pivot rearwardly toward the directional tail fin and thereby rotating the body about the center shaft, the inertia blocks being displaced radially by centrifugal force from an at rest position adjacent to the body, the springs thereby being extended and storing energy therein, and wherein, when the air stream force decreases, the springs urging the inertia blocks to return toward the at rest position, thereby releasing the stored energy and sustaining the rotation of the body.
Claim 2
Independent Claim
233 words
A device for storage and release of energy using centrifugal force, the device comprising: a body rotatably connected to a center shaft, a hood connected to the center shaft and extending forwardly of the body, a directional tail fin connected to the center shaft and extending rearwardly of the body, a pair of fins pivotably connected to the body, the fins being mounted diametrically opposed to one another and extending outwardly from the body, each fin being connected to an arm at approximately a right angle thereto, each arm having an end oriented toward the hood, two inertia blocks, one connected to the end of each arm, two springs, each spring connecting a respective arm to the body, wherein, an air stream directed toward the device is deflected by the hood toward the fins, the directional tail fin maintaining the body facing toward the air stream, the air stream engaging both fins and forcing the fins to pivot rearwardly toward the directional tail fin and thereby rotating the body about the center shaft, the inertia blocks being displaced radially by centrifugal force from an at rest position adjacent to the body, the springs thereby being extended and storing energy therein, and wherein, when the air stream force decreases, the springs urging the inertia blocks to return toward the at rest position, thereby releasing the stored energy and sustaining the rotation of the body.
Claim 3
Dependent Claim
17 words
The device of claim 1, wherein the springs are connected to respective arms near the inertia block.
Claim 4
Dependent Claim
35 words
The device of claim 1, wherein the respective arms each have a second end, the second ends extending rearwardly toward the directional tail fin, the springs being connected near the second end of each arm.
