The present invention is related generally to power generation, and more particularly, to an apparatus for generating power from wind energy by accelerating winds captured by a wind catcher module. According to a first aspect, a wind energy system comprises a wind turbine and a wind catch opening, in which there is a pressure-gradient force that accelerates the movement of air into the wind catch opening and onto the wind turbine. According to another aspect, a wind energy system comprises a wind turbine and a wind catch module that redirects wind from outside the wind energy system to the wind turbine in a direction substantially perpendicular to the wind turbine. According to yet another aspect, a wind energy system comprises a wind turbine, where the moving parts of the wind turbine are not exposed to humans, birds or other similar sized wildlife during normal operation.

What is claimed is: 1. A wind energy system comprising: a wind catch opening through which air enters the wind energy system; and a wind turbine; wherein air entering the wind catch opening is accelerated by a pressure-gradient force to the wind turbine, the wind energy system further comprising: an inlet through which air enters the wind energy system; an outlet through which air exits the wind energy system; and a cone-shaped structure located below the wind turbine, wherein a top opening of the cone-shaped structure that receives air flowing from the wind turbine is larger than a bottom opening of the cone-shaped structure; wherein the air received from the wind turbine and flowing from the top opening of the cone-shaped structure to the bottom opening of the cone-shaped structure is mixed with air that entered through the inlet before the mixed flows of air exit through the outlet. 2. A wind energy system according to claim 1, wherein the wind turbine is in a substantially horizontal plane. 3. A wind energy system according to claim 1, further comprising: a wind flow conduit that conducts air from the wind catch opening to the wind turbine, wherein an opening of the wind flow conduit near the wind catch opening is larger than an opening of the wind flow conduit near the wind turbine. 4. A wind energy system according to claim 1, wherein: air flowing from the top opening of the cone-shaped structure to the bottom opening of the cone-shaped structure is accelerated by the Venturi effect. 5. A wind energy system according to claim 4, wherein air is sucked through the wind turbine and into the cone-shaped structure. 6. A wind energy system according to claim 1, wherein: a surface area of an opening of the outlet is equal to or larger than a surface area of the wind catch opening at an entrance of the wind energy system. 7. A wind energy system according to claim 1, further comprising a wind catch module that comprises the wind catch opening, the wind catch module redirecting moving air outside the wind energy system to the wind turbine inside the wind energy system such that the redirected moving air moves substantially perpendicularly with respect to the wind turbine. 8. A wind energy system according to claim 1, wherein the wind turbine is enclosed such that moving parts of the wind turbine are not exposed to humans, birds or similar sized and larger wildlife during normal operation of the wind energy system. 9. A wind energy system according to claim 8, wherein blades of the wind turbine are located within a contained enclosure. 10. A wind energy system according to claim 1, further comprising a wind flow conduit that conducts air to the wind turbine such that the conducted air initially strikes only a portion of a blade in the wind turbine. 11. A wind energy system according to claim 1, further comprising a generator that converts mechanical energy generated by the wind turbine into electricity, wherein the wind turbine starts and brakes with the generator such that an increase in power drawn from the generator leads to an increase in torque demanded from the wind turbine. 12. A wind energy system comprising: a wind turbine; and a wind catch module that redirects moving air outside the wind energy system to the wind turbine inside the wind energy system such that the redirected moving air moves substantially perpendicularly with respect to the wind turbine, wherein: the wind catch module comprises a wind catch opening through which air enters the wind energy system; and air entering the wind catch opening is accelerated by a pressure-gradient force to the wind turbine, the wind energy system further comprising: an inlet through which air enters the wind energy system; an outlet through which air exits the wind energy system; and a cone-shaped structure located below the wind turbine, wherein a top opening of the cone-shaped structure is larger than a bottom opening of the cone-shaped structure; wherein the air that is received from the wind turbine and flowing from the top opening of the cone-shaped structure to the bottom opening of the cone-shaped structure is mixed with air that entered through the inlet before the mixed flows of air exit through the outlet. 13. A wind energy system according to claim 12, wherein the wind catch module comprises a wind guide that redirects moving air outside the wind energy system to the wind turbine inside the wind energy system such that the redirected moving air moves substantially perpendicularly with respect to the wind turbine, the wind guide being constructed of a flexible material that is substantially impermeable to the moving air. 14. A wind energy system according to claim 12, wherein the wind turbine is in a substantially horizontal plane. 15. A wind energy system according to claim 12, further comprising: a wind flow conduit that conducts air from the wind catch opening to the wind turbine, wherein the opening of the wind flow conduit near the wind catch opening is larger than the opening of the wind flow conduit near the wind turbine. 16. A wind energy system according to claim 12, wherein a surface area of an opening of the outlet is larger than a surface area of the wind catch opening at an entrance of the wind energy system.
