Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 241 words
A wind-powered generator comprising concentrator means for concentrating and focusing a fluid flow, the concentrator means having a flow chamber which defines a fluid flow path, a flared mouth which is located at one end of the flow chamber, a focusing surface which is located at the opposite end of the flow chamber, and a coupling port, the focusing surface having a focus located within the flow chamber; a turbine housing having an inlet and an exhaust port, the turbine housing being positioned within the flow chamber so that the inlet opens to the focusing surface focus, the focusing surface and the turbine housing inlet being positioned relative to one another so that the focusing surface receives the fluid flow from the fluid flow path of the flow chamber and focuses the fluid flow into the turbine housing inlet; an exhaust tube, open at both ends, extending from the exhaust port and through the coupling port to the exterior of the concentrator, the exhaust tube being communicatively coupled to the exhaust port so that the fluid flowing into the inlet is exhausted from the turbine housing to the exterior of the concentrator; a first turbine positioned in the inlet for rotation in response to fluid flowing into the inlet; and generator means for converting rotational motion into electrical energy, the generator means being communicatively coupled to the first turbine so that the rotation of the turbine is converted into electrical energy.
Claim 2
Dependent Claim 241 words
A wind-powered generator comprising concentrator means for concentrating and focusing a fluid flow, the concentrator means having a flow chamber which defines a fluid flow path, a flared mouth which is located at one end of the flow chamber, a focusing surface which is located at the opposite end of the flow chamber, and a coupling port, the focusing surface having a focus located within the flow chamber; a turbine housing having an inlet and an exhaust port, the turbine housing being positioned within the flow chamber so that the inlet opens to the focusing surface focus, the focusing surface and the turbine housing inlet being positioned relative to one another so that the focusing surface receives the fluid flow from the fluid flow path of the flow chamber and focuses the fluid flow into the turbine housing inlet; an exhaust tube, open at both ends, extending from the exhaust port and through the coupling port to the exterior of the concentrator, the exhaust tube being communicatively coupled to the exhaust port so that the fluid flowing into the inlet is exhausted from the turbine housing to the exterior of the concentrator; a first turbine positioned in the inlet for rotation in response to fluid flowing into the inlet; and generator means for converting rotational motion into electrical energy, the generator means being communicatively coupled to the first turbine so that the rotation of the turbine is converted into electrical energy.
Claim 3
Dependent Claim 23 words
The wind-powered generator as recited in claim 1 wherein the focusing surface is concave to the flow chamber and is parabolic in shape.
Claim 4
Dependent Claim 55 words
The wind-powered generator as recited in claim 1, wherein the turbine housing has a substantially ellipsoid shape, the housing having a major and a minor axis of rotation so that the inlet is positioned at one end and coaxially with the major axis, and further wherein the major axis lies along the fluid flow path.
Claim 5
Dependent Claim 17 words
The wind-powered generator as recited in claim 1 wherein the concentrator is mounted to a rotatable platform.
Claim 6
Dependent Claim 83 words
The wind-powered generator as recited in claim 1 further including a second turbine positioned in the exhaust tube for rotation in response to the fluid flowing through the exhaust tube; a first shaft for communicatively coupling the first turbine to the generator means, the first shaft extending from the first turbine and through the focusing surface; and a second shaft for communicatively coupling the second turbine to the generator means, the second shaft extending from the second turbine and through the generator means.
Claim 7
Dependent Claim 24 words
The wind-powered generator as recited in claim 1 wherein the generator means comprise a high-speed, high-torque electric generator; and a low-speed, low-torque electric generator.
