Abstract: A thermoelectric radiator for generating a direct current while providing at least a portion of the necessary cooling is formed with a first and second plurality of interdigitated thermoelectric lamella which are electrically joined and are connected to the positive and negative portions of the electrical system. The result is direct current flow when a heated coolant is passed over the lamella.

Abstract: A thermoelectric generator uses pulse combustion to generate heat used to heat plate elements of a thermopile in order to efficiently generate electricity. Stacked plates forming the thermopile also form an opening defining a combustion chamber and exhaust system. The exhaust system has a greater flow resistance adjacent the combustion chamber so that a self-sustaining pulse combustion can be maintained at lower temperatures.
