Abstract
A wind-powered machine system includes a base station including a fluid-powered machine for performing work and a crankshaft operatively coupled to the machine. The rotation of the crankshaft drives the machine to perform work. The system further includes a first and a second airfoil operatively coupled to the crankshaft and a system controller configured to selectively alter at least one of the altitude and in-flight orientation of the first and second airfoils. In a first stage, a wind-driven movement of the first airfoil in a first direction away from the base station causes the crankshaft to rotate. The rotation of the crankshaft causes a movement of the second airfoil in a second direction generally opposite to the first direction and toward the base station. In a second stage, a wind-driven movement of the second airfoil in the first direction away from the base station causes the crankshaft to rotate. The rotation of the crankshaft causes a movement of the first airfoil in the second direction toward the base station.
