This paper provides an overview on the theoretical aspects of a newly developed concept for harnessing the kinetic energy contained in random fluid hows of particles. Because of a number of constraints associated with current power-generating methods of utilisation of random and turbulent zero-head flows, such practices are bound to be inefficient and expensive. However, using a recently developed system and on the basis of the features introduced by the new concept, a large portion of the kinetic energy available from such zero-levelled, multidirectional and turbulent fluid motions can be captured effectively.
