Introduces the many ways in which man harnesses energy and increases his capicity to do work. Uses artwork to show man's first attempt to use energy; describes the discovery of the simple machines; explains that by using his mind man has able to achieve feats of strength that he once considered possible only in his imagination; and shows how man first realized that energy was stored within wood, running water, and wind.
