| 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 airborne with the body such that the vanes, when acted upon by
a wind force perpendicular to the axis, are operable to cause rotation about the axis, each vane comprising a horizontal blade
panel attached to and extending along the body;
one or more tethers coupled to anchor the body to a third point; and
one or more electrical generators airborne with the body to convert rotational energy produced by the rotation about the axis
into electrical energy,
wherein the blade panel is attached to the body along a first horizontal edge and
wherein the blade panel is detachably attached to the body along the first horizontal edge.
