John Worrell Keely

John Ernest Worrell Keely (September 3, 1837 - November 18, 1898) was an American mechanic and inventor who claimed to have discovered means of exploiting an etheric force to convert minute quantities of air and water into motive force, as a form of virtual perpetual motion, which he claimed to demonstrate using machines he constructed that were variously called vibratory-generators and hydro-pneumatic-pulsating-vacuo-engines. Keely was also, late in his life, linked to claims regarding an anti-gravity force called apergy, which certain of his defenders as well as sensationalist press accounts related he had discovered.
