Abstract
During thousands of years rotating waterwheel was used for converting of energy of moving water into mechanical energy of rotational motion. Thus, waterwheel (later – hydro turbine) represents the prime mover as simple machine-wheel and axle, which collides with water (as working medium) and gets the rotation of shaft for connection of useful mechanical load. Generally speaking the rotating waterwheel may be defined as paradigm in the classical hydropower discipline as normal science by Kohn [1], as well in the process of converting of mechanical energy. Nevertheless we may find the examples of alternative approach to a prevailing framework (paradigm). So, talented engineer, scientist and educator in Daniel W. Mead even in far away 1915 wrote in his fundamental book [2]: " … Mechanically, energy is exertion of force through space. As result this impressed force produces the motion of working medium in the space. If some mechanism being in contact (collides) with working medium is getting its own motion and is becoming the prime mover. In this way the transformation of energy can be performed up to various useful mechanical loads. Obviously, in hydro power we are dealing with gravity force and water as working medium, however other flowing masses (as sand, gravel, slurry and grain, etc) may be considered as working medium forced by gravity to input of new original prime movers. … " Actually we can see that " other flowing masses … as working medium ... forced by gravity " extends and modifies the phrase "hydropower" significantly and are associated with "new original prime movers " which should be invented evidently. This looks like a prevision of fundamental change in this framework. Finally, this new original prime mover was invented (and protected like IP product) as Discrete Power Converter (DPC). http://dpc-renewable-energy.com/ Thus, being based on Kahn's work an implementation of DPC (as original machine-compound levers with cross-linked mechanical feedbacks) in the process of converting of energy (in hydropower particularly) can be considered as paradigm shift because of transition from traditional (continuous) principle of operating and construction to another – self oscillation mode [3]. DPC represents the fundamental changes in the basic concept and experimental practice of prime mover powered by gravity as follows: 1. The operation of power converter in the regime of mechanical relaxation oscillator (unlike continuous rotating of waterwheel) under acting of gravity as input force for mechanism. Mechanically the relaxation oscillator generates a periodical sequence of short pulses (kinetic strokes) during which the useful work can be performed and some part of energy will be dissipated as losses (in the form of heat as usual). Between pulses the mechanism is motionless and the losses do not exist (just potential energy is accumulated). Because of fact that relaxation time is longer than short pulse the average losses are reduced in compare to continuous presence of losses in the continuous operating mode (like waterwheel).
