Patent ID: 8278776

Claim:
A reciprocating transducer powered by the kinetic energy of fluids, comprising: one or more upward thrust members; one or more downward thrust members; and an array of blades, moveable relative to each other in response to motion of the fluid, the array comprising: (a) a first configuration of the array, comprising a plurality of the blades ordered in a first grouping of pairs, in which the blades of each pair are driven apart from each other by the motion of the fluid, thereby creating a first linear excursion of the upward thrust members in an upward direction; and (b) a second configuration of the array, comprising a plurality of the blades ordered in a second grouping of pairs, in which the blades of each pair are driven apart from each other by the motion of the fluid, thereby creating a second linear excursion of the downward thrust members in a downward direction, the transducer further comprising means for configuring the array alternatingly between the first and the second configurations, so that the linear excursions of the thrust members alternate between motion in upward and downward directions at a constant frequency for a given velocity of the fluid.
