A personal refueling station for a personal-sized electric vehicle has a polygonal base structure housing a refueling system and a plurality of flat panels hinged thereto which open to form a flat surface and close up to an upright pyramid for storage. The flat panels have solar PV arrays mounted on their inside surfaces which generate electricity from sunlight in the open position. The electricity is used to generate hydrogen for hydrogen-fuel-cell vehicles, or is stored for recharging non-hydrogen electric vehicles. Alternatively, hydrogen or electricity may be provided from an external renewable power source. The station can also have utility hookups to provide excess hydrogen or electricity to an external energy usage, such as a home, business, or other station. The personal refueling station has a compact design that can be installed at home or business locations. It is designed to accommodate a personal-use electric vehicle such as an electric car or cart or a personal VTOL hovercraft. It can be used in a stationary location or transported for remote use, as well as operated by remote control.

A fiber optic cable includes a core and a surrounding protective layer. The core includes an inner tube having one or more optical fibers contained therein, and the surrounding protective layer includes an outer tube received over the inner tube, and a layer of buffer material positioned between the outer tube and the inner tube. The buffer material maintains the inner tube generally centrally located within the outer tube and providing a mechanical link between the inner tube and the outer tube to prevent relative movement therebetween. The inner tube may be coated with a low hydrogen permeability material to minimize the entrance of hydrogen into the inner tube. The low hydrogen permeability material may be coated with a protective layer of hard, scratch resistant material to protect the integrity of the low hydrogen permeability material. The area in the inner tube not occupied by the optical fibers may be filled with a filler material, the filler material being selected to have a sufficient viscosity to resist the shear forces applied to it as a result of the weight of the optical fibers within the tube while allowing movement of the optical fibers within the tube during spooling, deployment and handling of the cable to thereby prevent damage and microbending of the optical fibers. The filling material may be impregnated with a hydrogen absorbing / scavenging material to remove any excess hydrogen within the inner tube. The optical fibers have an excess length with respect to the inner tube, and the cable may include an outer jacket of a high temperature, protective material to protect the cable during handling and installation.
