author
A writer fascinated by bold mechanical ideas, best known for exploring the long human quest to build a self-moving machine. His work turns a technical dream into a lively historical survey of invention, hope, and persistence.

by Henry Dircks, Percy Verance
Little confirmed biographical information about Percy Verance is easy to find today, but he is known as the author of Perpetual Motion, a work that traces attempts to create machines that would run indefinitely under their own power.
Rather than reading like a dry technical manual, the book brings together historical examples, illustrations, and explanations of the inventors and devices connected with the perpetual-motion idea. That makes Verance especially interesting to listeners who enjoy the meeting point of science, engineering history, and human imagination.
Because reliable personal details are scarce in the sources I could confirm, it is safest to remember him through his subject: a curious guide to one of invention's most persistent and impossible dreams.
