Patent number: 7997059Abstract: A propulsion system for use in a liquid or gas fluid is provided including an axially-extending funnel-shaped conduit, a flow generator, a power source, and, optionally, an airfoil-shaped wing. The funnel-shaped conduit has outer walls forming an inner fluid passageway, an upper edge defining a fluid inlet, and a lower edge defining a fluid outlet. The optional airfoil-shaped wing is connected to and circumferentially surrounds the funnel-shaped conduit upper edge. The flow generator is rotatably mounted about the axis of the funnel-shaped conduit and is configured to force the fluid from the fluid inlet rearward through the fluid outlet.
