Thermoelectric generators (TEGs)

Electricity from waste heat: Thermoelectrics make hybrid vehicles more efficient

Thermoelectric generators (TEGs) convert heat into electricity. A promising application for this type of generator is the automotive sector: internal combustion engines use only about one-third of the energy contained in fuel for propulsion, with the remaining two-thirds lost as waste heat. As part of the RExTEG project, researchers from the German Aerospace Center (DLR) and the Fraunhofer Institute for Physical Measurement Techniques (IPM) have investigated the potential of this technology for use in hybrid and range-extended vehicles (REx). They have developed a working model for the first time, which is on display at Hannover Messe.
