Abstract
Abstract A THERMOELECTRIC ELEMENT AND PROCESS FOR THE DIRECT CONVERSION OF HEAT TO ELECTRICITY WHEREIN A TEMPERATURE GRADIENT ESTABLISHED IN A MOLTEN BISMUTH-BISMUTH BROMIDE OR BISMUTH-BISMUTH CHLORIDE COMPOSITION SERVES TO ESTABLISH A CONCENTRATION GRADIENT IN THE COMPOSITION AND A RESULTANT POTENTIAL DIFFERENCE. THE CONCENTRATION GRADIENT IS CONTINUOUSLY MAINTAINED IN THE COMPOSITION BY PREVENTING CONVECTIVE HEAT FLOW WITHIN THE COMPOSITION AND BY PASSAGE OF THE MORE VOLATILE BISMUTH BROMIDE OR BISMUTH CHLORIDE COMPONENT IN THE VAPOR PHASE FROM ONE PORTION OF THE MOLTEN COMPOSITION AT ONE TEMPERATURE TO ANOTHER PORTION AT A LOWER TEMPERATURE.
