The fourth photo in the above series appears to be the electric generator and the ninth photo is the combustion turbine unit. The combustion unit appears to contain 18 to 20 combustion nozzles. And, to put this thing in perspective, if this is an 100 mw unit that converts to approximately 134,000 horsepower.
