Abstract: A carbon nanotube (CNT) extrusion system includes a carbon source, an extrusion die having a baseplate having a plurality of die sets, each die set has a plurality of through-holes in fluid communication with the carbon source and a corresponding plurality of template tubes connected at one end to the baseplate and coaxial with the through-holes, each template tube includes a catalyst for forming a CNT structure in combination with the carbon source. An oscillating mechanism operatively associated with the free end of each template tube axially oscillates the template tubes to alternately form and release the CNT structure within each template tube in a continuous manner. The oscillating mechanism can be an alternating electric field or magnetic field applied to the template tubes, the frequency of the electric or magnetic field being synchronized with a formation rate of the CNT within the template tubes.

Abstract: A service station facility for replenishing various motivational energy sources onboard different types of automotive vehicles is disclosed herein. In one embodiment, the service station facility includes a rack, replaceable fuel tanks, a service module, and an electronic computer control system. The replaceable fuel tanks are stocked on the rack and substantially filled with various fluids, such as hydrogen, which are utile as motivational energy sources within fuel-operated automotive vehicles. The service module is mounted on the rack, and the electronic computer control system is connected in electrical communication with the service module. In this configuration, the service module is controllably operable to receive a depleted replaceable fuel tank from a fuel-operated automotive vehicle and also selectively deliver one of the filled replaceable fuel tanks onboard the automotive vehicle.
