ABSTRACT Two machines: The human body and the vehicle motor are made of structural and functional, natural and man-produced materials. They generate energy by chemical oxidation of two fluids: ethanol and gasoline. The characteristics of these fluids: a nutritive beverage and a fuel, providing motion to the vehicle, are described. The damage due to diseases in the body by excessive ethanol consumption and deterioration of the motor by corrosion are treated by means of preventive and curative methods: body rehabilitation and car repair, maintaining both machines in permanent, healthy, working operation. The chemical reactions of ethanol oxidation and gasoline combustion and their effects on the machines and their materials are presented, illustrated and discussed. INTRODUCTION Comparative studies on science, technology and society arouse a deep motivation for teachers and students in the pursuit of knowledge. They promote cognitive, professional and spiritual development of people thereby strengthening their comprehensive training, allowing them to achieve future events and approaches to solving their particular problems. The application of scientific and technological knowledge in a humanistic framework, allow addressing the problems of climate change, the new means of transport and communication, the industry sectors interlinks, online social networks, human interactions, with positive impacts on economic development, sustainability and welfare of the social environment. Figure 1 presents a graphic display of the relationship between science, technology and society for the benefit of mankind.
