ABSTRACT: Extended Heim Theory (EHT) suggests two additional gravity-like fundamental forces and proposes the possibility of propellant-less propulsion for space flight. If sufficiently safe and cost effective, technology spinoffs may prove to be disruptive for terrestrial applications. Applications based upon advancements in this field could have far- reaching implications for transportation, architecture, urban planning and industry. Coupled with promising distributed energy technologies of sufficiently high specific energy, the impact upon local economies, social systems and even representational democracies may be a challenge to future generations.
