However, it is difficult to deploy the vessel and tow the buoy separately from shore. They can be used to monitor activities onshore and the behaviour of other vessels. In fact, sufficient power can be harvested from the waves to not only power the electronics, but also to generate a supply of energy that can then be used to move the force.
The power module is 12.75 inches in diameter, the same as Remus 600 or BlueFin 12D AUV. However, the vessel may be configured with a plurality of swimmers, typically engaged at different depths to the same two or more tethers, each swimmer providing a translational thrust in response to wave action, optionally configured to nest when retracted (PCT/US 2012/029696). Thus, all aspects of the invention that derive wave power from a swimmer comprise or can be adjusted to comprise 2, 3, or more than 3 swimmers or wing frames.

In this configuration, the weight of the swimmer causes it to travel in the water below the hull, and the swimmer is configured to pull the hull through the tether. Fig. 5B superimposes 3 images showing what happens when the vessel approaches the apex of the wave. Fig. 5A, 5B, 6A and 6B are side views of a vessel, showing how wave motion can be converted into electricity. The on-board generator may comprise means for converting the vertical movement of the hull caused by wave motion into electrical power; means for converting horizontal movement of the hull through the water into electrical power; or both. When the vessel is equipped with means for determining the geographical position of the vessel, means for determining direction, means for manoeuvring the vessel, means for operating the manoeuvring, self-directed navigation can be performed so that the vessel travels or stays at a target position.

The position data regarding the geographical position and the vessel heading is processed in a decision algorithm or a programmed microprocessor, which may then provide navigation instructions. Resfriado dolor de espalda . The control unit may be located anywhere on shore within the scope of receiving and sending data and instructions, or it may be on board a vessel in a fleet, optionally integrated with the microcircuits of the vessel. The vehicle comprises a float or hull 10 at the surface of the water and a suspended swimmer 20 suspended below by one or more tethers 30. The floating body 10 includes a drain hull 11 and fixed keel fins 12. The swimmer comprises a rudder 21 for steering, and wings or fins 22 connected to the central beam of the frame 23, in order to allow the wings to rotate around the transverse axis and provide propulsion within a limited range.
As the waves lift hull 31, it pulls swimmer 32 upward. The processor calculates the appropriate heading and compares it to the heading input from the compass. As the journey continues, the iterative execution measures and corrects by comparing compass data with GPS. Wave motion may provide translational thrust through mechanical interconnection, such as in a ship where the float portion is tethered to 2 portions of the submerged portion. In this context, a “wave” is any upward and downward motion of the surface of a body of water at a reference point (such as the floating center of a ship). The included mechanical devices directly cause rotational motion (such as a rotating shaft) or can be mechanically converted to a reciprocating motion of rotational motion (such as a liquid-filled piston or a gas-filled piston).

Us patent No.4,134,023 discusses apparatus for extracting energy from waves on water. U.S. provisional patent application No.61/585,229 filed on month 10, 2012: “retractable nesting wing racks for wave-powered vehicles”. The wing frame then pulls the hull as directed by the rudder under the control of the microprocessor. After start-up, the pre-charged batteries power the vessel to deep water where the wing frames are deployed downwards and the towing buoy is deployed behind the floating body so as to be towed by the floating body without impairing the vertical movement of the floating body due to wave motion. After deployment, the batteries can be continuously recharged using the onboard power generation system.
L is the wavelength, HsIs the surface wave height, HyIs the diameter of the track at a depth y below the surface. 1A. The track at the surface has a diameter equal to the height of the wave. The processor then outputs instructions to the rudder servo to adjust the vessel to the correct heading.
The steering device is typically a rudder turned sideways against the water in order to turn the vessel to a new heading. Another option is a sensored tow buoy with servo-controlled lifting fins to modify the pitch of the tow to control its depth as it is pulled. Two or more wave-powered vessels of the invention may be organized as a fleet, interacting with each other and/or with a central control unit.
This may be provided by a photovoltaic cell located on the deck of the ship. Dolor lumbar muscular . Having 2 systems on a ship has several advantages. Vessels of this nature typically have: a floating hull; a swimmer configured to retract and secure against the hull; one or more tethers connecting the float to the swimmer; an electric motor configured to propel the watercraft via water; and a battery to power the motor, having sufficient capacity to power the vessel from shore to a location where the swimmer can be deployed.
The swimmer has a fin surface that mechanically provides a forward thrust when the fin surface is actuated by the ascent and descent of the swimmer in the water. The upward movement of hull 31 is slowed but the swimmer 32 still travels upward due to the tension in the arm as it is pulled downward.
A wave-powered vessel may be configured to navigate autonomously across the body of water (without human involvement) and perform its own power management. The power generation system may be configured to take advantage of vertical oscillations of the water surface in the wave cycle, or horizontal movement of the wave crest, or a combination of both. The waves raise and lower the float, creating pressurized water, which is then used to drive a hydraulic generator. The generator may be driven by the vertical and/or horizontal movement of the vessel caused by the waves.

U.S. Pat. No. 3,928,967, the so-called “soltt ducks (Salter’s Duck)” patent, is an apparatus and method for extracting wave energy. FIG. 3 shows the availability of solar energy as a function of the annual cycle and as a function of time (Advanced Robotics 16 (l): 2002, pages 43-55, adapted from MDAgeev). As the waves raise and lower the float portion, the wings or fins of the submerged portion are passively rotated to convert the relative motion of the surrounding water into forward thrust. A wave-powered vessel according to the invention typically has an electric motor to provide horizontal thrust, powering the vessel via the water. Typically equipped with a plurality of “fins” or “wings” that can rotate up or down about an axis transverse to the direction of travel.
