ABSTRACT The present invention provides a low cost, compact, efficient thermoelectric system which has no moving parts for converting waste heat into electrical energy. The system includes a plura- lity of heat pipes having at least one substan- tially planar sidewall and integral heat collect- ing fins. The heat pipes planar sidewalls enable broad surface thermal contact with thermoelectric devices. The heat pipes and integral heat col- lecting fins provide for the efficient collection and transmission of waste heat to the side of the thermoelectric devices contacting the heat pipes at a location outside of the flow of waste heat. The other side of the thermoelectric devices are either water or air cooled to establish a tempera- ture differential thereacross for the generation of electrical energy. The heat pipes are prefer- ably generally rectangular in cross-section to provide opposed substantially planar surfaces for making efficient, low heat loss, broad surface thermal contact with the thermoelectric devices.
