Abstract
A technology assessment of engines, power source and electrical technologies that can meets the needs of the future U.S. Army (“Army 21”) for cost-effective generator sets is made. Considered in this assessment are: diesel engines; stratified-charge, spark-ignited engines; homogeneous-charge, spark-ignited engines; gas turbine engines; and Stirling engines. Direct energy conversion devices including batteries, fuel cells, thermal-to-electric generators, and nuclear powered systems are also considered. In addition, potential advances in electric alternators and power conditioning, applications of networking, and noise reduction methods are discussed for possible application to the Army environment.
Recommendations are made for the potential application of the different technologies for the needs of Army 21.

- The full report considered a variety of different power sources. Nuclear power was considered in conjunction with thermionic, thermal-to-electric, and with external combustion heat engines. For reasons of safety, cost, weight, and commercial availability, nuclear power was ruled out as a practical candidate for mobile electric power. Stirling engines are expensive and not at a state of commercial development to consider very practical for the Army's purposes. Fuel cells for other than personal power backpacks were also ruled out. Thermoelectric devices running on fossil fuel were too heavy for personal power and efficiencies are too low for larger sizes. In the present paper we only focus on those technologies thought by the Committee to be reasonably attractive candidates for Army MEP: batteries and fuel cells for personal power; diesel, modified gasoline spark-iginited, rotary, Texaco Controlled Combustion System, and gas turbine engines.
