NOVELTY - A fossil fuel appliance (10) comprises a converter (14) capable of using a carbon-free hydrogen, a hydrogen storage container (12) including a nanostructured material (22) capable of storing the carbon-free hydrogen in a condensed state, a charger (16), and a discharger (20) for liberating the condensed carbon-free hydrogen from the nanostructured material of the hydrogen storage container to be available for use in the converter.    USE - For a fossil fuel.    ADVANTAGE - The inventive appliance is effective.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for:    (1) a hydrogen storage container usable in an appliance including a converter capable of using a carbon-free hydrogen, a charger, and a discharger, comprising a carbon-based nanostructured material and a metal capable of acting as both a seed for the formation of the nanostructured material and a facilitator for promoting the storage in a condensed state of the carbon-free gaseous hydrogen provided to the storage container;    (2) a continuous vapor deposition method for synthesizing a mixture of carbon nanostructures and metal nanoparticles, comprising, in a first stage, heating in an oxidizing flame a precursor, thus forming a metallic intermediate of nascent metal nanoparticles; in a second stage, heating in a cooler reducing flame the metallic intermediate formed in the first stage, thus forming metal nanoparticles and a mixture of nascent carbon nanostructures; and in a third stage, quenching and depositing on a cold substrate the metal nanoparticles that catalyze the nucleated growth of depositing carbon nanostructures, thus forming a mixture comprising carbon nanotubes, graphite encapsulated metal nanoparticles, and nanofibers; and    (3) a system for the continuous vapor deposition synthesis of a mixture of carbon nanostructures and metal nanoparticles, comprising an inline flame combustion chamber having an oxidizing zone and a cooler reducing zone that terminates with an exhaust exit, and a vapor deposition substrate that is cold, where the oxidizing zone has a burner having a fuel input line, an oxidant input line, and a precursor input line; the reducing zone has a burner having a fuel input line, an oxidant input line, and a coolant additive input line; and the exhaust exit is aligned with the vapor deposition substrate.
