A distributed simulation system is composed of simulator stations linked over a network that each renders real-time video imagery for its user from scene data stored in its data storage. The mounting arrangement comprises a housing having an electrical device receiving portion. A fuel mixer can adjust the methanol concentration of a mixed solution, and it adjusts the concentration of the mixed solution to an optimal methanol concentration for a load. The heater also includes a second material having a circular form and a second sheet resistively.
