Systems for material synthesis, powder processing, hot pressing, leg and SKD module fabrication are operational at MSU (ingot to couple 95% utilization of material) MSU has demonstrated 1, 5, 10 and 20 module (each 5-couple) TEGs which produced 5, 25 and 50.2 W and 75W, respectively at a ΔT ～ 550°C, heat supplied with gaseous N_2 (2.2 W/couple when heated directly at ΔT ～ 700°C) Using the performance of the Gen 1, 100 Watt generator demonstrated, we estimate that we would recover about 2.99 kW from the exhaust of an OTR truck at cruise conditions... Suggest we are five years from a viable 1/5kW systems with reliable performance provided one has adequate support! A 10% improvement in fuel economy would require a -1000% improvement in system performance over the Gen 1 system demonstrated in this work. We understand the path to a 300% improvement. A 10% bsfc improvement using TEGs for passenger car energy recovery applications with advanced engines will be very challenging. Substantial engineering and scientific developments required for practical application of TEGs for energy recovery in transportation: Reduce system degradation, couple resistance and heat transfer losses; Improve: module reliability, thermoelectric material properties, insulation and fabrication methods and heat exchanger designs are critical for this application.
