CHEMICAL FUELED THERMOELECTRIC GENERATOR.
Abstract
A proof-of-principle, thermoelectric device is described which is fueled with a high-energy (1875 calories per gram), high-density (1.8 grams per cubic centimeter) fuel slurry. Handling and storing the fuel for periods up to one year offered little difficulty; however, operating problems, such as fuel feed to the burner and ash removal from the burner, were not fully resolved. Two fuel feed systems were designed and tested; a gravity drop system which is suited to low power output devices of up to 5 watt electrical output and a pressurized, continuous fuel feed system which is suited to devices about 5 watts electrical output. The thermoelectric generator yielded the following data: eta thermoelectric modules = 4.95%, calculated; eta overall = 2.91%, measured; voltage and current = 0.7V at 8.8 amperes; and power out = 6.16 watts.
