Abstract: Certain exemplary embodiments provide a system adapted to generate hydrogen, which can comprise a water supply source, hydrogen producing agent, hydrogen collector, hydrogen purifier, a hydrogen outlet, a fuel cell, a storage device for electricity, and an inverter. The inverter can be adapted to convert direct current (“DC”) electrical energy into alternating current (“AC”) electrical energy.

Abstract: Certain exemplary embodiments can provide a system comprising a hybrid composite. The hybrid composite can comprise tubular carbon and graphene produced via pyrolysis of a milled solid carbon source under an unoxidizing environment. When analyzed via X-ray diffraction, the hybrid composite can generate peaks at two theta values of approximately 26.5 degrees, approximately 42.5 degrees, and/or approximately 54.5 degrees.

Abstract: The expandable shelf of the invention is formed of several telescoping tubular assemblies that are supported in parallel to one another between a pair of end plates. The tubular assemblies may be press fit into the end plates. The end plates are mounted to opposed walls. A center bracket is provided to supportably mount between the end plates for embodiments having long or flexible tubes. In another embodiment, one end plate is mounted to a wall and a second end plate is supported on a floor-mounted column. A further embodiment includes support plates that are mounted to wall surfaces and further receive the end plates to support the expandable shelf. An additional embodiment includes a solid surface platform that is adjustable in length to mount onto the expandable shelf.
