Abstract: A combined power conversion and carbon capture and recycling subsystem including a fossil fueled oxidation unit, a physical adsorbent CO2 capture medium, rotor, motor, heater, CO2 compressor, diffuser and water storage tank. Exhaust gas from fossil fuel oxidation is scrubbed of CO2 via passage across a physical adsorbent and then released from the adsorbent via fuel oxidation waste heat. High CO2 concentration scrubber exhaust air is then compressed and fed to a diffuser which facilitates dissociation of the CO2 into water where it is temporarily stored for use in watering plants. Carbon from fossil fuel is recycled back into the environment and permanently stored as biomass by natural means of photosynthesis.
