Abstract

A wind power generating system is disclosed. The wind power generating system comprises a plurality of blades to capture wind energy; a shaft coupled to the plurality of blades, and a power extractor for extracting power from the rotation of the plurality of blades. A rotation of the plurality of blades occurs in response to the captured wind energy, and a lift force is generated from the captured wind energy by the plurality of blades that is substantially along the shaft.

Claims (18)

1. A wind power generating system comprising:

a shaft, wherein the shaft is inflated;

a blade to capture wind energy, wherein a rotation of the blade occurs in response to the captured wind energy and wherein a lift force is generated from the captured wind energy by the blade that is substantially along the shaft; and

a generator coupled to the blade, wherein a propeller is directly coupled to the generator enabling the generator to generate electricity by capturing wind energy.

2. A wind power generating system as in claim 1 , wherein the blade is one of a plurality of blades.

3. A wind power generating system as in claim 1 , wherein the generator is one of a plurality of generators coupled to the blade.

4. A wind power generating system as in claim 1 , wherein the blade is inflated, and wherein the blade is comprised of a flexible material.

5. A wind power generating system as in claim 1 , wherein the shaft is comprised of a flexible material.

6. A wind power generating system as in claim 1 , wherein the propeller is used to control the rotation of the blade around the shaft, by controlling the power output of the generators that are coupled to the propeller.

7. A wind power generating method comprising:

inflating a shaft, wherein the shaft is inflated;

capturing wind energy using a blade, wherein a rotation of the blade occurs in response to the captured wind energy and wherein a lift force is generated from the captured wind energy by the blade that is substantially along the shaft, and wherein the blade is comprised of a flexible material; and

generating electricity by capturing wind energy using a generator, wherein the generator is coupled to the blade, wherein a propeller is directly coupled to the generator enabling the generator to generate electricity by capturing wind energy.

8. A wind power generating method as in claim 7 , wherein the blade is one of a plurality of blades.

9. A wind power generating method as in claim 7 , wherein the generator is one of a plurality of generators coupled to the blade.

10. A wind power generating method as in claim 7 , wherein the blade is inflated, and wherein the blade is comprised of a flexible material.

11. A wind power generating method as in claim 7 , wherein the shaft is comprised of a flexible material.

12. A wind power generating method as in claim 7 , wherein the propeller is used to control the rotation of the blade around the shaft.
