Claim Text:
1. A method of operating a turbine engine comprising: providing air to the turbine engine as compressor intake air and as compressor bypass air; passing the compressor intake air through a first stage compressor to generate first stage compressed air; passing the first stage compressed air into a boiler; heating a coolant by passing the coolant as a liquid into the boiler to extract energy from the first stage compressed air; and passing the first stage compressed air from the boiler into a second stage compressor; pumping the coolant through the boiler to a heat exchanger that is heated from an exhaust stream of the turbine engine, the coolant flowing from the heat exchanger to a closed cycle turbine to cause the closed cycle turbine to rotate; and extracting energy from the rotating closed cycle turbine as auxiliary energy.
