An energy generating module comprises an enclosure, an energy generating device, a fuel chamber, and one or more fuel conveying devices. The enclosure comprises a plurality of walls that enclose the energy generating device. The fuel chamber is applied to an exterior surface of at least one wall of the enclosure such that at least a portion of the exterior surface of at least one enclosure wall is covered by the fuel chamber. The fuel conveying devices convey fuel from the fuel chamber to the energy generating device enclosed by the enclosure walls. The energy generating device generates an energy output using fuel received from the fuel chamber.
