According to some embodiments, systems and methods for tethered wind turbines may be provided. In some embodiments, a system may comprise an airborne body extending horizontally along an axis between a first point and a second point, wherein the body is at least partially filled with a gas. The system may further comprise, for example, two or more vanes coupled to the body such that the vanes, when acted upon by a wind force perpendicular to the axis are operable to cause the body to rotate about the axis to generate a Magnus effect lifting force. According to some embodiments, the system may comprise one or more tethers coupled to anchor the body to a third point.

What is claimed is: 1. A system, comprising: an airborne body extending horizontally along an axis between a first point and a second point, wherein the body is at least partially filled with a gas; two or more vanes coupled to the body such that the vanes, when acted upon by a wind force perpendicular to the axis are operable to cause the body to rotate about the axis to generate a Magnus effect lifting force; one or more tethers coupled to anchor the body to a third point; and one or more electrical generators mounted on the airborne body to convert rotational energy produced by the body rotating about the axis into electrical energy. 2. The system of claim 1, wherein the body is primarily held aloft by the Magnus effect lifting force. 3. The system of claim 1, wherein the body defines an envelope pressurized with the gas. 4. The system of claim 3, further comprising: a ballonet disposed within the envelope to regulate the pressure of the gas. 5. The system of claim 1, wherein the one or more tethers comprise one or more electrical cables to transfer the electrical energy toward the third point. 6. The system of claim 1, further comprising: one or more stabilizers coupled to facilitate orientation of the axis perpendicular to a prevailing wind force. 7. The system of claim 6, wherein the one or more stabilizers comprise a stabilizer integral to the body. 8. The system of claim 7, wherein the integral stabilizer defines a portion of an envelope pressurized with the gas. 9. The system of claim 8, wherein the integral stabilizer is inflatable. 10. The system of claim 1, further comprising: an end plate coupled to the body at each of the first and second points on the axis, wherein each of the end plates comprises a securing point disposed on the inner surface of the end plate. 11. The system of claim 10, further comprising: a structural member extending substantially along the axis and coupled to each of the securing points of the end plates. 12. The system of claim 1, further comprising: a Darrieus-type rotor coupled to the first and second points and operable to rotate about the axis and around the body when acted upon by the wind force perpendicular to the axis. 13. A system, comprising: a tethered wind turbine including an airborne body extending horizontally along an axis between a first point and a second point, wherein the body is at least partially filled with a gas; two or more vanes coupled to the body such that the vanes, when acted upon by a wind force perpendicular to the axis are operable to cause the body to rotate about the axis to generate a Magnus effect lifting force; and one or more tethers coupled to anchor the body to a third point; a ground station, receiving electrical energy from the tethered wind turbine and transmitting the electrical energy for use in powering one or more electrical devices, wherein said tethers are coupled to at least one of said body, a projection, or a generator. 14. The system of claim 13, the ground station further operable to convert the electrical energy into a different form prior to transmitting the electrical energy for use. 15. The system of claim 13, wherein the tethered wind turbine is primarily held aloft by the Magnus effect lifting force. 16.
