Described herein is a novel and useful cross fluid-flow axis turbine (CFAT) that converts the energy of a flowing fluid to rotational energy. The invention includes an axle rotatably mounted on a frame. In one embodiment a plurality of arms extending outwardly from the axle. Each arm has at least one beam that supports at least one outer foil and an inner foil, the inner foil being positioned between the inner most outer foil and the axle. The upper surfaces of the foils face toward the direction of rotation of the axle so that lift generated by the foils contributes to the rotation of the axle. The foils are oriented and aligned so that fluid flowing into the turbine is redirected by the inner foils to the leading edge of the outer foils. The flow of fluid through the center of the turbine can be restricted by a baffle or by placing the inner edge of the inner foils sufficiently close to the axle. The CFAT can be used as a wind turbine or a water turbine through simple modification of the frame and support structure.
