1. A tractor-trailer waste heat recovery system, comprising:
a conduit configured to receive waste heat from a power source of a tractor-trailer and to establish a first flow path for the waste heat from the power source to the surrounding environment;
a waste heat inlet that is configured to receive waste heat from the conduit and that is configured to establish a second flow path that branches off the first flow path for the waste heat received from the conduit;
a heat exchanger that is in fluid communication with the waste heat inlet via the second flow path and that is adapted to extract a thermal heat value from the waste heat; and
a turbogenerator in fluid communication with the heat exchanger, adapted to receive the thermal heat value from the waste heat and to convert the thermal heat value from the waste heat into generated electricity;
wherein the first flow path is configured to direct waste heat that does not enter the waste heat inlet to the surrounding environment without passing through the heat exchanger.
