    Abstract: A Hydrogen storage system comprising storage elements coupled to each other to form one or more containers disposed in a space having a volume V where the volume of each of the storage elements is much smaller than the volume V resulting in the storage elements experiencing reduced stress at their inner surfaces. Thus, Hydrogen can be stored at relatively high pressure within these storage elements due to the reduced stress experienced by their inner surfaces. Consequently, materials having relatively lower tensile strength and stiffness can be used to construct the storage elements of the Hydrogen storage system. Further, the storage elements can be shaped and sized to conform to a volume of space having an arbitrary shape and dimensions.

    Abstract: A heat transfer tube for a water-spray-panel evaporator for the gasification of liquefied natural gases which includes a tube having a pair of planar members each projecting outwardly from its peripheral surface, radially with respect to its longitudinal axis and extending longitudinally along such axis, and an internal fin disposed within the tube and having at least three fin members each projecting radially with respect to the longitudinal axis to provide a helical formation extending along and about the longitudinal axis, the helix of the helical formation contacting the internal wall of the tube in a pressure-fitting relationship. The heat transfer tubes can be assembled to form a panel evaporator. The method for fabricating such heat transfer tubes and assemblies is characterized in that the above pressure-fitting relationship is established by drawing the tube alone to reduce its internal diameter until the helix of the helicoid is abutted against the internal wall of the tube.
