A submergible wave energy converter and method for using the same are described. In one embodiment, the wave energy converter may be used for deep water operations. In one embodiment, the submergible wave energy converter is an autonomous unmanned vehicle that enables remote ocean power generation. In one embodiment, the wave energy converter apparatus comprises an absorber having a body with an upper surface and a bottom surface and at least one power take-off (PTO) unit coupled to the absorber and configured to displace movement of the absorber body relative to a reference, where the power take-off unit is operable to perform motion energy conversion based on displacement of the absorber body relative to the reference in response to wave excitation, and where the power take-off unit is operable to return the absorber body from a displaced position to a predefined equilibrium position and to provide a force acting on the absorber body for energy extraction.

Disclosed is a system for deploying, stationing, and translocating buoyant wind- and wave-energy converters and/or other buoyant structures or devices, as well as farms of same. Also disclosed is a novel apparatus and/or machine comprising a farm of buoyant wave energy converters deployed by said method and/or configured to be deployed by said method.

A smart wave energy converter may include a reconfigurable floater; a reference wave frequency measurement module; a central control module; a submerged buoyancy element; one or more power take-off devices; and an anchoring system. The reconfigurable floater may be connected to the submerged buoyancy element by the one or more power take-off devices. The submerged buoyance element may be connected to the anchoring system. The reconfigurable floater may include one or more mechanisms to alter a natural heave frequency of the reconfigurable floater. The reference wave frequency measurement module may measure a frequency of a wave state and transmit a measured frequency to the central control module. The central control module may adjust a property of the one or more mechanisms to match the natural heave frequency of the reconfigurable floater to the measured frequency.

A floating mooring system for a single CycWEC applies counter forces and torques to keep a generator suitably stationary for power generation without requiring fixed attachments to the ocean floor or requiring a large frame interconnecting multiple CycWECs. The mooring system uses floats or floatation structure with differential ballasting to counter operating torque and drag plates to counter reactive forces. The floatation structures may be used to float the CycWEC for transport to a deployment location, where changing the overall ballasting of the floatation structures submerges the CycWEC to a desired depth and differential ballasting in the floatation structures counts expected operating torques.

A system (100) for producing electricity from wind energy is provided. The system comprises a balloon (110) configured for inflation with a buoyant gas. The system further comprises at least one turbine-generator system (120) coupled to the balloon, comprising a turbine and generator. The turbine is configured to rotate when subjected to an external airflow. The generator is coupled to the turbine and is configured to convert rotation of the turbine into electricity. The system further comprises an electrical storage system (230) for storing the generated electricity.

Disclosed herein is a power generating apparatus for extracting energy from flowing water. The apparatus comprises a buoyancy vessel, and a turbine assembly coupled to the buoyancy vessel which comprises a turbine rotor mounted to a nacelle, and a support structure. The turbine assembly is pivotally moveable between a first position and a second position. When the power generating apparatus is floating on a body of water, in the first position the nacelle is fully submerged below the water surface; and in the second position at least a part of the nacelle projects above the water surface. Movement of the turbine assembly from the first position to the second position is buoyancy assisted, for example by providing the turbine assembly with positive buoyancy or selectively increasing its buoyancy. Movement of the turbine assembly to the second position may be desirable to reduce the draft or the drag of the power generating apparatus, for example when the power generating apparatus is being relocated, or to prevent damage during storms. In addition, when in the second position it is possible to gain access to the nacelle for maintenance or repair.
