An improved circular multi-element semiconductor thermoelectric hybrid utilizes a make-before-break high frequency switching output component to provide nominal alternating current voltage outputs. Overall efficiency of heat conversion is improved by coupling a chiller to the thermoelectric generator where exhaust heat produces chilled liquid or air that is conveyed to the cold side of the thermoelectric device. The thermoelectric generator is used in a variety of transportation vehicles including manufactured vehicles, retrofitted vehicles and vehicle power combinations.
