Claim:
A motion generating system to produce a relative thermodynamic force between an object and a region of adjacent fluid comprising: a primary surface located on the object and in contact with part of the region of adjacent fluid, an implosion zone positioned adjacent the primary surface in the adjacent fluid, wherein adjacent fluid flows over the primary surface according to the relative motion between the object and the region of adjacent fluid, a target zone positioned in the region of adjacent fluid and upstream in the flow transfer path of the adjacent fluid that flows over the primary surface, a means for introducing fluid, where the means for introducing fluid is located on the object, a working fluid in a gaseous state which is hotter than the region of adjacent fluid and the primary surface, and the working fluid is introduced by the means for introducing fluid, from the object into the target zone, wherein the working fluid is introduced with momentum in a direction substantially perpendicular to the direction of the flow path of the adjacent fluid through the target zone, thereby ejecting and displacing a portion of the adjacent fluid laterally from the flow path, and a portion of the introduced working fluid is entrained in the flow and moves from the target zone with any un-ejected adjacent fluid, along the flow transfer path into the implosion zone, and, when the working fluid enters the implosion zone, heat exchange between the working fluid, the primary surface, and the adjacent fluid in and around the implosion zone, causes a condensing phase change in at least 20% of the working fluid which enters the implosion zone, producing an implosion process with a dynamic pressure reduction in the implosion zone, and the working fluid is a gas at least 20% of which is capable of condensing at the dynamic pressures and temperatures occurring in the implosion zone at the start of and during the implosion process, whereby the dynamic pressure reduction in the implosion zone produces a relative thermodynamic force between the object and a region of adjacent fluid causing reduced drag, increased lift, acceleration, and propulsion in the relative motion, between the object and the adjacent fluid.
