Abstract : The Department of Defense (DOD) is concerned with reliable and cost-effective power generation of on-site power generators as well as minimizing the environment impact of these generators. Thermoelectric (TE) devices offer the opportunity to generate power without additional fuels, without moving parts, and with negligible environmental impact. An electrical energy conversion efficiency of approximately 15% would be required to obtain an acceptable return on investment for TE devices. A feasibility study to was performed to determine how, assuming a 16% efficiency, TE devices could impact the DOD's power generation capabilities. Based on research indicating energy conversion efficiencies of 20%, TE devices were built and tested. Of 27 TE devices supplied, only 8 were functional; each device produced only 1 Watt of power. Current manufacturing processes and design parameters were assessed and recommendations made. Three locations were prepared as demonstration sites for TE devices, site evaluation criteria were outlined, and process results given. Control an Data Acquisition (CDAQ) Systems for single and multiple test stands were developed to gather all necessary data variables during the demonstrations, and a portable technology system was developed to enable personnel to demonstrate the technology in any location.
