We proposed and fabricated a thermoelectric generator (TEG) using the engine water coolant of passenger vehicles. The experimental results revealed that the maximum output power from the proposed thermoelectric generator was ∼75 W, the calculated thermoelectric module efficiency of the TEG was ∼2.1%, and the overall efficiency of electric power generation from the waste heat of the engine coolant was ∼0.3% in the driving mode at 80 km/h. The conventional radiator can thus be replaced by the proposed TEG without additional devices or redesign of the engine water cooling system of the existing radiator.
