1. A turbine wheel, comprising:
an inner hub having a central axis, an outer ring concentric with the inner hub, and an intermediate ring concentrically disposed between the inner hub and the outer ring,
a plurality of turbine blades extending between the intermediate ring and the outer ring;
the turbine blades being oriented to be driven by a stream of fluid flowing through the turbine wheel to rotate the turbine wheel in a first direction about the central axis; and
a plurality of compressor blades extending between the inner hub and the intermediate ring, each compressor blade including a leading edge and a trailing edge;
the compressor blades being oriented to propel the stream of fluid in a direction downstream of the trailing edges of the compressor blades and axially with respect to the central axis when the turbine wheel is rotated in the first direction.
