Thermoelectric power generation and cooling has always been limited to very specialized applications, due to low efficiency and high cost. Very recent theoretical work (paper to be published soon) indicates the possiblity of a new class of devices based on new materials and very thin multi layers, with dramatically enhanced figures of merit that would make them competitive. At the stage of basic R&D, first application of interest is cooling of electric vehicles. LNLL has a relationship with MITand a company that is developing solid state replacements for alternators on truck diesels (which use waste exhaust heat).
