Described herein is a novel and useful cross fluid-flow axis turbine (CFAT) that converts the energy of a flowing fluid, wind or water, 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 compnses at least one outer foil and an inner foil, the inner foil being positioned between the inner most outer foil and the axle. The foils are shaped 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
