An apparatus for extracting power includes a track and an airfoil coupled to the track. The track includes first and second elongate sections, where the first elongate section is positioned above the second elongate section. The airfoil includes a suction surface lying between a pressure surface and the track, and is moveable in opposite directions when alternately coupled to the first elongate section and second elongate section.
