ABSTRACT:
A method and apparatus for generating power and for increasing the temperature of heat in a thermodynamic machine wherein a working fluid is circulated within a rotating rotor. In the machine, the rotor contains a heating heat exchanger and a cooling heat exchanger within the rotor, and also a working fluid heat exchanger to transfer heat from one stream of working fluid into another stream, so that one stream is heated and another cooled. The working fluid heat exchanger is in one or more steps, so that the working fluid stream into which heat is added, is being expanded during heat addition, and also the stream may be compressed with heat addition. Heat removal from the other working fluid stream may also be in steps. The machine may be a single rotor unit, or may have two rotors. Alternately, one of the rotors may be held stationary in some instances, to improve working fluid circulation within the machine cavity.
