NOVELTY - A nanotube article comprises nanotube films (99) stacked in continuous web, where the nanotube films including first nanotube film having nanotubes aligned in first direction, the first direction being at first angle relative to length-wise edge of the web; and second nanotube film having nanotubes aligned in a second direction, being at second angle relative to the length-wise edge of the web, where the second angle is different than first angle.    USE - As nanotube article, for growing fullerene nanotube forests, and forming nanotube films, threads and composite structures; used in high-strength fibers, threads, yarns, fabrics, and reinforcement for composites, e.g. nanotube-reinforced epoxy structures; for storing hydrogen gas, especially for hydrogen-powered fuel cells; for carbon fibers and/or nanotube materials include catalyst supports, materials for manufacturing devices, such as a tip for scanning electron microscopes, electron field emitters, capacitors, membranes for filtration devices as well as materials for batteries.    ADVANTAGE - The nanotube article prevents or repairs gaps in a nanotube film being pulled from a nanotube forest.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) apparatus for continuous fabrication of carbon nanotube film comprising first film-transport mechanism having nanotube-film-holding surfaces, and movable along first fabrication path; and layer-build-up mechanism operable to place carbon nanotube film across the nanotube-film-holding surfaces while the nanotube-film-holding surfaces are moving along the fabrication path; and    (2) method involving providing interior-flow substrate having first major face, first nanoporous surface layer in fluid communication with first major face, interior flow system operable to deliver gasses to nanoporous layer from side or face of substrate other than the first major face, and nanotube-synthesis catalyst on the first nanoporous layer, and delivering nanotube-precursor gasses into the interior flow system and through the nanoporous layer to the first major face.
