This work explores the historical pursuit of self-motive mechanisms, detailing various devices aimed at achieving perpetual motion and the fundamental reasons for their failures. The authors attempt to educate readers on the mechanical principles behind these inventions while emphasizing that true perpetual motion is impossible according to established scientific understanding. The opening of the book introduces the author’s perspective on the long-standing fascination with perpetual motion and the collective efforts over centuries to create self-sustaining machines. It highlights the historical context by referencing previous works, particularly those of Henry Dircks, who critically assessed numerous perpetual motion devices. The text further sets the stage for a comprehensive classification of these inventions, beginning with illustrations and descriptions of early attempts, such as those by Wilars de Honecort and Leonardo da Vinci. It underscores how despite the ingenuity of these efforts, they ultimately failed due to fundamental misunderstandings of physics and mechanical principles.
