1. Students use a search engine to find information about who invented the microprocessorThe first automobiles were powered by steam. This technique, although suitable for large vehicles like boats and trains, was not practical for smaller individual automobiles. So, a century after it was invented, in 1770, the automobile was still considered a toy. Imagining how such an engine could effectively replace the steam powered engines of automobiles, the mechanic Gottlieb Daimler tried to build a much lighter engine working on the same principle. In 1885, he came up with a very light 2-step combustion engine that was used for boats, velocipeds and even tram ways. A few years later, in 1889, he invented a 4-step combustion engine that is the direct ancestor of the engine we find in our cars today.
