Challenges: 1) Low T H (<374 0 C for steam) 2) compressor and turbine to handle two-phase tluids. Challenges: 1) Isentropic compression to high pressure 2) Isothermal heat transfer at variable pressures Can the Carnot Cycle be used with steam? (T critical =374 o C (647.1 K), P critical = 22.06 Mpa)
