Since the plate is partially on the surface level, the device is exposed to rough sea damage. In rough seas, the system is at least partially above the surface of the water, even if it is below the surface under mild conditions, resulting in damage. Two strike plates would be used, one above and one below the turbine blades, a limit the pivot in each direction. U.S. Pat. No. 4,083,189 above. U.S. Pat. No. 4,249,383 issued to Molini et al. U.S. Pat. No. 4,001,597 also describes a wave energy recovery system in which a pump unit is fixed to the seabed. The pump unit is located in shallow water and the pressure plate reaches or slightly below the water surface. When the foil arrives at the surface or a predetermined depth, it is advantageously docked in a frame, where couplings for pipes/conduits ensure that the pressurized air is transferred to storage tanks for further transport.

103) as possible. This corresponds to the situation where the hydrofoil is at its uppermost position (h1).The housing has a valve (120) and an inlet through which the compressible fluid can be supplied. Dolor muscular gluteos . Fig. 1 is a schematic view of a wing or hydrofoil having at least one pressure tank during a cycle of compression and surfacing with pressurized air. By using air as load, one goes directly from kinetic energy to pressurized air, a potential energy which in turn is an excellent energy carrier. This implies that more load can be applied to the hydrofoil proportional to the decreasing buoyancy, which in turn implies that the string can be further loaded by the pulley which is connected to an energy utilizing device.

The deeper the hydrofoil is brought, the higher the pressure it is exposed to, which causes V2 to decrease correspondingly. U.S. Pat. No. Dolor muscular en hombro izquierdo . 1,768,716 issued to Shishkoff describes a water driven motor is used to drive a friction heater which produces steam. The U.S. Pat. No. The mouth of the chamber is rectangular or oblong, with the longer axis running substantially parallel to the shoreline. The hub rotates with the power take off shaft 30, which turns on bearings 32 (only the upper bearing is shown in FIG. The turbine blades are each axially balanced and free to rotate about an axis concentric with the shaft (change their pitch). The turbine blades 10 are shaped for maximum efficiency in motion and may be narrower at their inner ends than at their outer ends. As a system for recovering kinetic energy from waves, a system fixed to the bottom of a lake or the sea is also known.
If the period is much longer than the period of the waves, it acts as a stable platform. WO 98/17911. This device is attached to the bottom of the water and recovers wave energy from a plate that is rocked by waves. Some of these devices are listed and described below. It is to be understood that the present invention is not limited to the stole embodiment described above, but encompasses any and all embodiments within the scope of the following claims. Such a system is represented by an apparatus described in International Patent Application Publication No. By converting to energy carriers such as, for example, batteries or hydrogen by known methods, energy loss is suffered at each conversion.
The present invention concerns a method and apparatus for converting kinetic energy in a flow of liquid using a hydrofoil. US 6 273 680 shows an apparatus for converting the kinetic energy in a fluid flow tu usable energy by means of a plurality of thin foils (aero- or hydrofoils) disposed in the flow. The Gulf Stream is driven by the Coriolis-effect caused by the Earth’s rotation. The Gulf Stream conveys water at a rate between 30 000 000 m3/sec (30 Sv) and 80 000 000 m3/sec (80 Sv). Again, it makes direct use of the water itself and not the changes in air pressure that accompany moving water sources.
The energy acquired in this manner depends on the variables: Area, speed and mass, which is transformed to pressurized air. The counterbalances 23 should be made of material which is dense, so as to balance the weight of the blades 10, and also hard and strong enough to resist the forces resulting from hitting against the strike discs. This system helps to eliminate the large sized reservoirs need to operate present day hydroelectric stations. This device interacts directly with the tide or current to produce the power. If the hydrofoil is attached to a string, advantageously a wire, this can be wound around pulleys attached to a mooring apparatus in the depth of the liquid and in a floating or submerged surface platform respectively. At the same time, these end walls are locked in position once the volume reaches a certain size and the hydrofoil has reached a predetermined depth.
It is another object of the present invention to provide an oscillating force turbine that utilizes a turbine having pivoting blades that react to the change in air pressure, allowing air flow to exit out the top of the chamber or return into the chamber. Yoga para dolor lumbar . This deflection of the air will cause a reaction force to be imparted to the blade 10, the reaction force being in the direction of the side of the blade 10 having the smaller area. Also, the position of this system creates a second problem that the wave motion in the shallows is too irregular to achieve regular energy production. The device is located at the bottom of the area between the wave breakline and the shallows. The chamber opening is located just below the surface of the ocean, that is, just below an elevation equal to the mean water level minus the wave amplitude.

This location yields a greater motion of water, since the displacement of the water as a surface wave passes diminishes with depth. As an alternative to adjusting the angle of attack, the profile of the wing might be altered to achieve the required lift and down force. In a breakline, the wave motion and thus the energy gained is irregular and unsuitable for continuous energy production.
