Definitions

  • This invention relates generally to the field of energy generation and more specifically to an apparatus and a system for energy generation from movement of water and even more specifically to an apparatus and a system for energy generation from reciprocating water flows.
  • the reciprocating motion may vary over time, as the wind direction may change. However, for certain places, the reciprocating flow may substantially have the same direction during most of the time.
  • energy from waves has high power near the surface of water. This may be an advantage for high power generation; however, it may be a disadvantage due to wear and tear. Likewise, it is realized that the energy from waves may have less power below the surface. However, the motions below surface may be calmer, which may result in less wear and tear.
  • US 6,955,049 discloses a machine and system for power generation through movement of water using electrical turbines.
  • the invention discloses an embodiment for power generation from current that comes from a first direction or a second direction, which is substantially opposite the first direction.
  • a system using turbines is, however, relative complex, it may be relative expensive to produce, and it may pose the risk that a member in the water gets stuck within a turbine, which can result in a block or a destruction of the turbine.
  • a turbine may not be a preferred way to exploit the above mentioned reciprocating motions.
  • water can be construed as any kind of liquid, e.g. fresh water and salt water.
  • the water may be brackish water. It is a further object for the present invention to partly or completely remedy some or all of the deficiencies in existing systems for generation of energy from motion of water.
  • an apparatus for exploiting reciprocating motion of water comprising a base; a first water actuated member movably connected to the base; wherein the first water actuated member is adapted for being actuated by a reciprocating motion of water, such that at least a part of the first water actuated member moves in substantially the same direction as the water flow, whereby the first water actuated member performs a motion in relation to the base, and the first water actuated member is adapted to drive an energy generating system.
  • an energy generating system comprising an apparatus according to the above-mentioned and a pump and/or an electrical generator, where the pump and/or electrical generator is in drivable connection with the at least one water actuated member is provided.
  • a water actuated member refers to a first water actuated member.
  • An apparatus according to the present invention may comprise a plurality of water actuated members. It is an advantage for the present invention that the apparatus according to the invention comprises a simple structure. For this and possibly other reasons, it may be less likely that an apparatus according to the present invention may be jammed or broken by a member in the water or by the forces from the water itself.
  • a member in the water may in this sense be a natural member e.g. seaweed or the like, or a man- made member e.g. a tin can or the like.
  • a water actuated member according to the invention may comprise a large, smooth single surface that may enable a significantly great force to be transferred by a single motion.
  • the base may be intended to be situated on an ocean bed or another stable, partly stable, or semi-stable place, e.g. a reef, a barrier reef, an offshore bar, an artificial ocean bed or another man-made or natural environment.
  • ocean bed may refer to any of such mentioned environment.
  • the base is intended to be situated directly on a substantially flat ocean bed.
  • the base may be fixed to the ocean bed.
  • An apparatus may furthermore comprise at least one drive member in drivable connection with the first water actuated member, where the at least one drive member is adapted to drive an energy generating system.
  • a water actuated member may comprise a pane, a plate, or any other substantially plane member.
  • a water actuated member may comprise a member with a substantially curved surface.
  • the water actuated member may have a circumferential shape of any geometry, such as a substantially triangular shape or any other substantially polygon shape, where the polygon comprises more than three line segments.
  • the water actuated member comprises a substantially plane pane with a circumferential shape that is substantially a rectangle. The size of this rectangle is preferable around 1 by 1 meter, but it may be bigger and it may be smaller.
  • the water actuated member may have a substantially uniform thickness throughout the member, which may reduce production cost compared to alternatives.
  • the thickness of the water actuated member may vary throughout the member.
  • the thickness of the member may be the thickest near a connection to a drive member, and the thinnest close to an edge of the water actuated member. Using this principle, material use and consequently weight may be reduced while having similar or better capabilities of withstanding stress compared to a water actuated member with a uniform thickness.
  • an apparatus according to the invention is made of a corrosion-resistant and/or a rustproof material.
  • the water actuated member may be rotatably connected to a base by a joint.
  • a joint may comprise a connection point that allows one degree of rotational freedom between the water actuated member and the base.

  • the operation of a stop member may result in a substantially sudden and complete stop of a movement of a water actuated member and/or a connected drive member if the water actuated member or the drive member reach a certain position.
  • the operation of a stop member may result in a gradually increasing resistance as a water actuated member or a drive member moves in a given direction.

  • a water actuated member may be able to be affected by a plurality of stop members.
  • a water actuated member may be affected directly, and/or it may be affected through one or more drive members.
