Magenn Air Rotor System - US20060251505

This patent application was submitted in 2005. If accepted it will expire by 2025.
The patent application by Fred Ferguson of Magenn Power Inc. describes this invention as a "tethered wind turbine".

"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."

Magenn Power Inc. is one of a new breed of Kite 2.0 companies with kite-based technology.
