This study was performed to determine the most optimum energy conversion technique for a man-pack power source in the power levels of 10, 25, and 100 watts. These power levels were investigated at two separate energy demand rates of one to nine duty cycle and a one to one duty cycle. The most critical requirements in this effort were weight and volume. The power sources were allowed 4, 15, and 25 pounds respectively and a volume which could be integrated with the communications equipment on a standard military back-pack board. The results of this engineering investigation indicate that batteries of the AgZnO variety appear to be best for all power levels at the one to nine duty cycle. The fuel cells are inherently lighter systems in the 10 and 25 watt design one to one duty cycle but it is not conclusive that they are superior to thermoelectrics in the 100 watt, one to one duty cycle. In the 100 watt size all pertinent criteria must be weighted and evaluated prior to a final choice. Author
