sCO2 Allam-Fetvedt oxy-combustion power cycle
Natural gas burns in near-pure oxygen, diluted by a large recycled supercritical-CO₂ flow instead of air's nitrogen — the oxy-combustion, near-critical-CO₂ cycle that yields pipeline-ready CO₂ with no separate capture step. Main compressor takes CO₂ from just above its critical point (310 K, 8 MPa vs. Tc=304 K/Pc=7.38 MPa) to 30 MPa; the combined CO2+combustion-product stream expands through a real isentropic-efficiency turbine, still supercritical throughout.

View & openRankine steam power cycle (pump -> boiler -> turbine -> condenser)
The classic steam power cycle behind most of the world's electricity, on the rigorous IAPWS-97 steam properties. Feedwater is pressurized by a boiler-feed pump, fired to superheated steam in the boiler, expanded through a steam turbine to make shaft power, then condensed back to water in the surface condenser. The four Rankine components appear in order, and the numbers are the real thermodynamic ones: at 60 bar / 500 degC steam expanding to a 0.1-bar condenser vacuum the turbine makes ~18 MW of shaft work at 85% isentropic efficiency, the exhaust leaves the turbine as wet steam (~92% quality, the classic low-pressure blade-erosion concern), the condenser rejects ~40 MW to cooling water, and the feed pump costs only ~0.15 MW (the small back-work ratio that makes the Rankine cycle practical, since pressurizing a liquid is nearly free next to expanding a gas). Cycle thermal efficiency comes out ~28%. Every property (the superheat enthalpy, the isentropic expansion endpoint, the exhaust steam quality) is the real IAPWS steam-table value, not a correlation.
