A 195-year-old discovery is behind a new system that will save vehicles hundreds of litres of fuel and reduce their carbon emissions by as much as 1,000 tonnes per year.
Working with automotive manufacturer Scania, researchers from KTH Royal Institute of Technology have been testing semi trucks equipped with a system that converts exhaust heat into power — through a process called thermoelectric generation (TEG). The voltage produced by the system can power the truck and reduce the strain on the engine, explains researcher Arash Risseh.
