Abstract

An apparatus comprising: a traveler connected to an elongate track; a stator comprising an elongate conductor spaced from the elongate track, a first ferromagnetic unit, and a second ferromagnetic spaced from the first ferromagnetic unit, wherein each ferromagnetic unit comprises a first end proximal to the conductor and a second end distal to the conductor; and a translator coupled to the traveler comprising a base partially surrounding the conductor and extensions positioned on either side of a sequence of ferromagnetic units.

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 is moveable in opposite directions when alternately coupled to the first elongate section and second elongate section.

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 pressure surface lying between a suction surface and the track, and is moveable in opposite directions when alternately coupled to the first elongate section and second elongate section.
