1. A moving wall positive displacement turbine system comprising:
a housing and
a central body positioned concentrically within the housing, wherein a channel is delineated between a first running surface of the housing and a second running surface of the central body, wherein the first running surface and the second running surface are each contoured according to a polygonal profile with a plurality of lobes;
a first low friction wall being attached to the first running surface;
a second low friction wall being attached to the second running surface;
a ring positioned within the channel having a plurality of radial slots;
a plurality of vanes slidingly attached within and passing through the plurality of radial slots, wherein the plurality of vanes is pivotally attached between the first low friction wall and the second low friction wall;
wherein the first low friction wall, the second low friction wall, the ring and the vanes form spaces with variable geometry; and
wherein the housing and the central body are rotationally coupled; and
a plurality of fuel injection ports being configured to inject an air-fuel mixture into the spaces for combustion as the housing and central body and the ring experience rotation relative to each other.
