The present invention includes counterbalancing arms on the rotors 14. In other embodiments, the number of turns on the helix could be selected in order to counterbalance the device 100. For example. The device could consist of 0.95 turns. This allows ships to pass over the device or around it. Additionally, barrages result in static water building up behind the device, where pollutants may accumulate. The angle of incidence may oscillate between less than ±90°, preferably ±80°, most preferably ±60g.

The helix may preferably have a diameter larger than a width of the supports 12. The width being defined in a direction transverse, preferably perpendicular, to the plane. At any given point, a large proportion of the swept area is covered such that greater energy can be recovered than previous devices. An energy generating apparatus is provided according to claim 13. This apparatus may effectively form a tidal fence, which extends across a wider area of water to increase energy generation. The fast-moving turbine blades may also suffer from cavitation phenomenon, which can gradually abrade the turbine blades. At each point the generated acceleration is such as to drive the rotor in the correct direction. The angle of the fin is driven by a torque motor to move the hydrofoil relative to the member and relative to the direction of water flow to vary a direction of lift produced by the hydrofoil and thereby drive the member in its oscillatory path.

Each fin axis of rotation may be generally parallel to the plane. That is, the flow of fluid is generally parallel to the plane. Dolor en la espinilla de la pierna . The fins 16 are rotatably attached such that they can rotate between a first position in which the first impingement surface is arranged to contact a flow of water in a first direction generally parallel to the plane and a second position in which the second impingement surface is arranged to contact the flow of water. This will be described in more detail later but is relevant to ensure that a constant rotating movement is imparted to the rotors 14. The joints 14A of the rotors connect to a connection portion 16A of the fin 16. This connection is such that as the rotors rotate about the first and second axes, the fins 16 oscillate between the first and second positions to ensure that the generated acceleration is in the correct direction to ensure continued rotation of the rotors.
In order to achieve this, each fin 16 may be substantially rotationally symmetrical about its centre for 180° of rotation. The first and second impingement surfaces are provided on opposite sides of the fins 16. Each fin 16 is rotatably attached at the joints 14B. This rotatable attachment is about a fin axis of rotation. The first rotor 14 extends between the first and second supports 12. In particular, the first rotor 14 is rotatably mounted to the first and second supports 12. The rotational mounting is about a first axis of rotation.

The generators may be provided inside the supports 12. That is, the supports 12 may include a portion for retaining the generator, for example in an integral unit. A plane is defined which passes through both of the supports. As the fins oscillate they will present different ramped surfaces for impingement. Acido urico dolor de rodilla . That is, the fins oscillate between two positions where each impingement surface is presented to a flow of water in a given direction. That is, each individual support 12 may be as branches from a larger support for the entire structure. The first and/or second central portion may each comprise one turn. The second axis of rotation is also in the plane and is offset from the first axis of rotation. The flow direction referenced above refers to the general direction which the entire fluid flow can be characterised by.
For example, the helix angle could vary along the length of the device 100 in order to optimise the device for flow in a single direction. In a river application, this may be defined by the direction of flow of the river (i.e. The energy transfer device may further comprise a second generator attached to the second rotor. The present invention relates to a tidal or hydropower energy generating device. This optimises the energy transferred from the flow of fluid to the rotation of the rotors. Accordingly, the power output from a single device will be relatively low and each device must be quite complex. In this sense the device 100 could be used to generate a flow of water. As each fin 16 is rotatable in this manner, the device 100 is reversible.
