A gas or liquid foil propulsion system is disclosed with internal wings or flaps which are positioned within a looped device. The ambient fluid (e.g. water of a body of water) or gas (e.g. air) flows through this loop and past at least one foil or air foil which is the wing or flap. This creates lift in the entire device. In some embodiments, the air foils are preceded by guide vanes which direct the flow of the ambient fluid or gas. In some embodiments, the loop is bifurcated creating two different paths of flow with the wings/flaps only in the outer sections of the bifurcation. In some embodiments, vents are used to allow inflow of the ambient medium. The device can be made of modular units which connect to each other to form, for example, a rectangular, circular, square or other shaped flow path.
