1. A centrifugal compressor comprising a casing including an impeller having a gas intake and an outlet, the impeller having an input drive, and an impulse turbine rotor positioned around the periphery of the impeller adjacent the outlet, the impulse turbine rotor driving an output shaft, the impulse turbine rotor to be driven by high velocity gas exiting the impeller whereby the impeller has a plurality of radial impeller blades at a gas exit of the impeller configured to maintain the high velocity of the gas exiting the impeller blades, wherein the pressure of the gas entering the impulse turbine rotor is maintained at an exit of the impulse turbine rotor and a stator is positioned between the exit of the impeller and the impulse turbine rotor that redirects exiting gases to the impulse turbine rotor.
