Patent ID: 7229029

Claim:
A propulsion system, comprising: a vehicle engine for selectively driving a stream of propulsion fluid, whereby said vehicle engine is adapted for mounting in a vehicle, the stream of propulsion fluid being composed of a fluid through which the vehicle is moving; a conduit connected to said vehicle engine, the stream of propulsion fluid flowing from said vehicle engine through said conduit, said conduit extending along a longitudinal axis; and a propulsion altering attachment disposed on said conduit, the attachment having a generally elongated, open, substantially S-shaped slit having inwardly and outwardly opposing portions defined therein, said propulsion altering attachment being positioned on said conduit such that the stream of propulsion fluid flowing through the substantially S-shaped slit travels substantially along the longitudinal axis; wherein said propulsion altering attachment and said substantially S-shaped slit are dimensioned and configured for expelling and shaping the stream of propulsion fluid flowing from said vehicle engine, and through said conduits, in a substantially three dimensional spiral pattern.
