TECHNOLOGY FOCUS - ELECTRICAL POWER AND ENERGY - Preferred Component: The engine is an internal combustion engine. It further includes an intake manifold, and injector(s) communicable with the combustion chamber. An exhaust extends from the combustion chamber and passes products of combustion. A secondary recovery system is in fluid communication with the exhaust including an expansion mechanism. The secondary recovery system includes a first stage that receives exhaust gas from the exhaust and expands the exhaust and passes it through a secondary exhaust port. A second stage receives the exhaust from the first stage, and further expands the exhaust and emits the exhaust. A separator is fluidly connected to the exhaust of the first and/or second stages. Scalable passages transfer fuel, oxygen and noble gasses to the combustion chamber with minimal intrusion of ambient air. An air chiller has an inlet for receiving air. It includes at least one flow medium for flowing at least one of argon or oxygen. The exhaust is passed through a biomass including a biomass field of a plant material, an inlet for receiving carbon dioxide from the exhaust the engine, and an outlet for transporting the gasses emitted by the biomass for further processing. A biomass recovery system converts the biomass into a hydrocarbon. A regeneration transport system provides the hydrocarbons generated from the biomass to the combustion chamber of the engine. A fuel line extends between the injector and a supply of fuel and communicates with the injector. The manifold communicates with a supply of ambient air. A switcher communicates the engine with a supply of fuel and noble gas to the manifold and a supply of combustion gas to the injector; or a supply of air to the manifold and a supply of fuel to the injector. A drive train is connected to the power output, and provides propulsion for a vehicle.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Component: The fuel is a hydrocarbon fuel.    TECHNOLOGY FOCUS - BIOLOGY - Preferred Component: The biomass is an algae field.    TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Component: The gasses emitted by the biomass are oxygen.
