Claim 16:
17. The system of claim 16, wherein the recuperator subsystem includes:
a first recuperator for receiving the second quantity of sCO2 from the Brayton-cycle turbine and extracting a first degree of heat therefrom to produce a fifth quantity of sCO2 having a temperature less than the second temperature;
a second recuperator serially coupled to the first recuperator for receiving the fifth quantity of sCO2 and extracting heat therefrom to produce a sixth quantity of sCO2 having a temperature less than a temperature of the fifth quantity of sCO2;
a third recuperator serially coupled to the second recuperator for receiving the sixth quantity of sCO2 and extracting heat therefrom to produce a seventh quantity of sCO2 which is lower in temperature than the sixth quantity of sCO2; and
where heat extracted from the second and third recuperators is used by the first recuperator to help produce the third quantity of sCO2.
