Transportation has evolved from walking to using animals to using technology, mainly the automobile. The first automobile was steam-powered built in 1769 by the inventor Nicolas-Joseph Cugnot. The steam-powered automobile was redesigned to used the internal combustion engine in 1808 by François Isaac de Rivaz using hydrogen as the fuel source. The fuel source for the internal combustion engine was switched to gasoline in 1870 by Siegfried Marcus. Gasoline is still the primary fuel for the automobile 148 years later.
