Abstract
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.
Claims20
An apparatus for extracting power comprising:
- a track comprising first and second sections and a terminal connecting the first and second sections;
- an airfoil moveable in opposite directions when alternately coupled to the first section and second section, wherein the airfoil pitches or yaws as it travels along the terminal;
- and
- a power generator to harvest power from a fluid through the movement of the airfoil.

An method of extracting power comprising:
- providing a track comprising first and second sections and a terminal connecting the first and second sections;
- coupling an airfoil to the track such that the airfoil pitches or yaws as it travels along the terminal;
- positioning the track so that the airfoil travels crosswind to a fluid flow;
- and
- harvesting power from the fluid flow through the movement of the airfoil.
