A system or subsystem for fabricating articles of two or more different materials Including systems or subsystems for fabricating articles of said two or more different materials, for removing at least one of CH4, CO2 or carbonate from the environment, and for utilizing at least one of CH4, CO2 or carbonate as a feedstock for fabrication of at least one of said different materials, said system or subsystem comprising:
- means for removing at least one of CH4, CO2 or carbonate from the environment, comprising an intake through which a fluid stream is flowed;
- a first molecular binding tool for binding one molecule of said CH4, CO2 or carbonate removed from the environment;
- a second molecular tool or a second molecular binding tool for binding a single reagent molecule or a single reactant molecule or intermediate;
- and,
- means for contacting said one molecule of said CH4, CO2 or carbonate removed from the environment bound to said first molecular binding tool to said second molecular tool or said single reagent molecule or a single reactant molecule or intermediate bound to a said second molecular binding tool,
- wherein:
- said means for contacting is selected from the group consisting of:
- actuators and nanopositioning means;
- said first molecular binding tool and said second molecular tool or a second molecular binding tool for binding a single reagent molecule or a single reactant molecule or intermediate are in communication with said means for contacting;
- and,
- wherein said first molecular binding tool comprises at least a ligand skeleton, and said first molecular binding tool and said second molecular tool or said second molecular binding tool for binding a single reagent molecule or a single reactant molecule or intermediate are situated on one or more structural members of said system or subsystem.
