Comparative studies facilitate interaction between students and teachers, to explain and understand the similarities and differences that exist in the fundamentals, processes and events of nature, based on oxidation-reduction reactions such as animal and plant respiration(1), combustion of fuels, corrosion of metals(2,8). The present article compares the metabolism of ethanol in the human body with the combustion of gasoline in a vehicle motor. It considers the natural, soft functional materials of the body and the man-made, hard structural materials of a motor as the respective reactor vessels. The characteristics of the reactant fluids involved: ethanol, a beverage and gasoline, a fuel and their chemical reactions are described. The damage to the human organs and tissues and to the motor mechanical components by these interactions between reacting fuel and reactor structures is evaluated. The preventive and curative protection methods are assessed. At the end, a section on the pedagogical aspects of comparative studies is provided, including teaching of Science Technology and Society (STS) to postgraduate students of engineering(9,10).
