Every year the American Society of Mechanical Engineers (ASME) has a competition called Human Powered Vehicle Challenge. This competition is about the design and manufacture of green vehicles with the purpose to help underdeveloped countries. Also it has the purpose of reducing the global impact of gasoline. The HPVC has four events: Design, Innovation, Velocity and Endurance. All the teams put their effort for over one year, using what they learn in engineering classes to design and manufacture their masterpiece for the competition.
