摘要： Methods and systems are provided for nautical stationkeeping of free-floating objects. In one example, a method includes adjusting translational motion of a body freely floating in water by rotating the body. The translational motion may be adjusted, for instance, to maintain the body within a geographic area. In certain examples, the adjustment of the translational motion may be realized via a Magnus effect induced by rotating the body. The body may be configured as, for example, a free-floating object such as a wave engine.

摘要： A deployable wave energy harvesting device for autonomous underwater vehicles (AUVs) includes a deployable lifting platform and an energy harvesting mechanism. The deployable lifting platform includes two scissor-type lifting structures, which are supported by a double-end threaded rod. A first stepper motor is connected to a threaded rod passing through a threaded hole at a center of a slotted pin shaft, and drives the threaded rod to lift and lower the deployable lifting platform. A spindle on the energy harvesting mechanism is connected to a generator. A support frame is hung at the end of the spindle. A scissor-type single-pendulum structure is hung at the lower end of the support frame. A load is hung on the end of the scissor-type single-pendulum structure. Second and third stepper motors are installed on the support frame to lift and lower the load by rope drive.

摘要： An energy-harvesting compute grid includes computing assemblies that cooperate with mobile energy harvesters configured to be deployed on a body of water. The plurality of energy harvesters are positioned on and move adjacent to an upper surface of a body of water, and the locations of the energy harvesters can be monitored and controlled. The wide-spread gathering by the harvesters of environmental data within that geospatial area permits the forecasting of environmental factors, the discovery of advantageous energy-harvesting opportunities, the observation and tracking of hazardous objects and conditions, the efficient distribution of data and/or tasks to and between the harvesters included in the compute grid, the efficient execution of logistical operations to support, upgrade, maintain, and repair the cluster, and the opportunity to execute data-gathering across an area much larger than that afforded by an individual harvester (e.g., radio astronomy, 3D tracking of and recording of the communication patterns of marine mammals, etc.). The computational tasks can be shared and distributed among a compute grid implemented in part by a collection of individual floating self-propelled energy harvesters thereby providing many benefits related to cost and efficiency that are unavailable to relatively isolated energy harvesters, and likewise unavailable to terrestrial compute grids of the prior art.

摘要： An ocean wave energy absorbing kite system 200 captures an ocean wave's kinetic energy as a force on a submerged, reciprocating panel 202 that drives the panel back and forth in an oscillating motion. The force applied to the panel is transmitted to a power generator 244 through opposed flexible ropes or lines 214, 224 loaded in tension. Potential energy is captured from the wave as a vertical force when a buoyant volume attached to the energy absorbing panel or kite member 202 rises on a passing ocean wave's peak, and transmits the force through flexible ropes or lines in tension to a power generator. Optionally, the shape of the panel is configurable to limit or restrict absorbed wave energy, thereby preventing damage from larger storm-generated waves.
