Abstract: These apparatuses consist of devices and systems to conserve energy in action/reaction processes. Instead the excess current drawn when accelerating motors to move the earth will be omitted as a result of the starting operation. Generators, machinery, and vehicles will be more efficient and less polluting. This is done by means of a counter weight, spring means, or a brace and for stationary and moving systems. For cars, trains and other vehicles, a strong static spring further extended by a counter weight/gravity or external cable opposing the backward travel of the travel media will be effective. Braking may be complemented by deflecting a strong spring which allowed to expand to resume travel.
