An automobile (or motor car) is a wheeled passenger vehicle that carries its own motor. Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to seven people, typically have four wheels and be constructed principally for the transport of people rather than goods. However, the term is far from precise.
In 1806 François Isaac de Rivaz, a Swiss inventor, designed the first internal combustion engine (sometimes abbreviated "ICE" today). He subsequently used it to develop the world's first vehicle to run on such an engine that used a mixture of hydrogen and oxygen to generate energy. The design was not very successful, as was the case with the British inventor, Samuel Brown, and the American inventor, Samuel Morey, who produced vehicles powered by clumsy internal combustion engines about 1826.
