Abstract
An electrical power generator comprises a capturing element (1) attached to a base (1000) in correspondence with a first end (11) thereof. The capturing element is located in a fluid and configured such that, when the fluid moves, the capturing element generates vortices in the fluid which produce an oscillating movement of the capturing element (1). The capturing element (1) has a cross section with a characteristic dimension, which decreases from a first longitudinal position (11A) located closer to the first end (11) than to a second end (12) until a second longitudinal position (12A) located closer to the second end (12) than the first longitudinal position (11A).
Claims37
An electrical power generator comprising:
- a capturing element having an elongated shape, the capturing element extending in a longitudinal direction between a first end of the capturing element and a second end of the capturing element, wherein the capturing element has a length between the first end and the second end,
- the capturing element being configured to be attached to a base and submerged in a fluid with the first end closer to the base than the second end, the capturing element being configured such that, when the fluid moves, the capturing element generates vortices in the fluid so that an oscillating lift force is generated on the capturing element, which produces an oscillating movement of the capturing element;
- and
- a subsystem for converting the oscillating movement of the capturing element into electrical energy;
- wherein the capturing element has a cross section with a characteristic dimension,
- wherein the characteristic dimension decreases from a first longitudinal position located closer to the first end than to the second end until a second longitudinal position located closer to the second end than the first longitudinal position.

- and
- a subsystem for converting the oscillating movement of the capturing element into electrical energy, the subsystem being at least partially housed inside the capturing element;
- wherein the subsystem comprises:
- a plurality of coils comprising at least three coils arranged side by side in a plane perpendicular to a longitudinal axis of the capturing element and preferably substantially symmetrically in relation to said longitudinal axis, and
- at least one pair of magnets arranged to produce a magnetic field;
- the coils and the magnets being arranged so that the oscillating movement of the capturing element produces a relative movement between the at least one pair of magnets and the coils so as to generate an electromotive force in the coils.
