New Thermoelectric Materials and Devices for Terrestrial Power Generators

The development of new, more efficient, materials and devices is the key to expand the range of appplications of thermoelectric generators. New potential terrestrial applications have been recently described in the literature. There exists a wide range of heat source temperatures for these applications. Recent results on novel materials have demonstrated that ZT values significantly larger that 1.0 could be obtained in the 475 to 975K temperature range. These materials are excellent candidates to be used in terrestrial thermoelectric power generators using waste heat or liquid fuels.
