Inventors, scientists and engineers experimenting with the capture of steam under pressure discovered that the expansive force of steam could be used to power machines, or in chemical processes. The basic steam engine and its variations were used for pistons, cranks, and pumps to power cars, boats, farm equipment, construction vehicles, and locomotives.
