Abstract: A gas turbine engine is provided. The gas turbine engine includes a turbomachine having a compressor section, a combustor, and a turbine section arranged in serial flow order, the turbomachine further including an outer casing; a fuel cell assembly positioned within the outer casing of the turbomachine, the fuel cell assembly including a fuel cell and an output products line in fluid communication with an outlet of the fuel cell for receiving output products from the fuel cell; a fuel delivery assembly including a fuel line; and a reformer in communication with the fuel line and the output products from the fuel cell during operation of the gas turbine engine to convert a fuel flow through the fuel line to a hydrogen rich gas.

Abstract: An end-weighted vehicle comprising a framework having opposing ends and a wheel mounted to one of the ends for rotation and defining a footprint, and a weight supported by the framework proximate the wheel so as not to interfere with the rotation of the wheel, wherein a)the weight is sufficiently heavy and sufficiently distributed proximate the wheel so that the framework is forced to reside in an inclined position with the other of the ends positioned above a supporting surface when the wheel is positioned against the supporting surface, and b)the footprint is of a size sufficient to support and maintain the framework in the inclined condition.
