At the 6th World Conference of Chemical Engineering in Melbourne in September 2001 we held the final of the first Australasian Chem-E-Car Competition. This tradition has continued for every Chemeca and 2007 in Melbourne is no exception! The competition is for undergraduate students. The objective is to design and construct a car that uses a chemical reaction to power it and to control the distance it travels carrying a specified load. The competition is about demonstrating ability to control a chemical reaction. This year teams from Adelaide, Curtin, Queensland, Auckland and Canterbury universities will compete for the coveted Chem-E-Car Trophy.
