In order to improve the efficiency in the transmission of potentials of differents types, it is possible to implement transmission elements and a method with an ideal configuration as to the space-time-dynamics in all technical fields. In the method 1, the global configuration of the transmission elements, for example toothed wheels, is modified so that they are separated into two or a plurality of elements having the same operation mode, with out-of-phase actuation, so that the potential to be transmitted is brought at the ideal set time, from the transmission element having a lower efficiency to that which has a higher efficiency. In the method (2), the global configuration of the transmission elements is modified so that their ratios as to the path, the surface or the volume during the unequal efficiency cycles are ideally determined from the spatial point of view as a function of the angle covered (for example a crank-shaft angle). The increase of the effective path or surface during the higher efficiency period and the reduction of the effective path or surface during the lower efficiency period enable to obtain efficiency gains. Thereby, a favorable torque is obtained, for example in the case of a bicycle, by means of an elliptic driving gear.
