Claim Text:
1. An apparatus for extracting power comprising: a track comprising first and second elongate sections, wherein the first elongate section is positioned above the second elongate section, and wherein a terminal connects the first elongate section to the second elongate section; an airfoil comprising a suction surface and a pressure surface, wherein the airfoil is coupled to the track so that the pressure surface lies between the suction surface and the track when the airfoil is alternately coupled to the first elongate section, the second elongate section, and the terminal, wherein the airfoil is moveable in opposite directions when alternately coupled to the first elongate section and second elongate section, and wherein a distance from a start to an end of the terminal is shorter than a distance from a start to an end the first elongate section and shorter than a distance from a start to an end the second elongate section; and a power generator to harvest power from an atmospheric wind through the movement of the airfoil.
