"supercritical CO2 315 degrees C using heat exchanger... injected into turbine, driving shaft spins coiled copper wire interacts with magnets of generator produce electricity.... cooled in heat-recovery... passes to compressor raises its pressure before enters recuperator, which reheats the sCO2 with the excess thermal energy collected in the previous step. Once heated, sCO2 reenters main heater to start cycle again... 10 kilowatts produced and injected into grid for 50 minutes without interruption"
