Closed Propulsion see www.approachconcepts.com closed engine accelerated through geometric structure--- shows force of new engine inside floating container. See new book that explains theory "Closed Loop Space Propulsion". This system has no moving parts.
Book describes and proves a closed propulsion system in which the restrictive law of conservation of momentum is not implemented or required. This system does not suffer from the decaying forces of mass expelling systems such as rockets, either chemical, plasma or ion, it uses a unidirectional force created by changing the direction of a liquid metal Gallium Indium alloy.
