Abstract:
1. A power generator for use in a unidirectional flowing fluid as a source of energy comprises; a fixed part comprising a first tube adapted to be fixed with respect to a flowing fluid; a movable part comprising a second tube telescopically coupled with the first tube for reciprocal movement with respect to the first tube between first and second positions; a valve element carried on the movable part and adapted to move between an open position at which fluid flow with respect to the movable part is relatively unimpeded and a closed position in which the fluid flow with respect to the movable part is impeded to thereby move the movable part to the second position; a valve actuation mechanism connected to the valve element to move the valve element to the closed position when the movable part reaches the first position and to move the valve element to the open position when the movable part reaches the second position; and an electrical generator coupled to the fixed part and the moveable part and adapted to generate electrical energy when the movable part moves between the first and second positions.
