Resumen de: GB2631651A
A method of energy harvesting comprises providing a pivotally mounted transfer plate 30 for receiving a load, loading a bearing surface of the transfer plate with a transversely moveable dynamic load, transferring a resulting linear movement of the transfer plate to a drive shaft 50 as a rotational output via a one-way clutch 60. An energy capture device for carrying out the method comprises the transfer plate pivotally mounted within a housing (10, figure 1), and a generator 90 driven by the drive shaft. A surface of the transfer plate opposed to the bearing surface may comprise at least one output actuator 36 proximal to a periphery of the transfer plate. The device may further comprise a load member 20 to receive a source load and comprising a head 24 which abuts the bearing surface of the transfer plate and is transversely moveable there along. Transverse movement of the load member relative to the transfer plate causes eccentric loading of the transfer plate which pivots relative to the housing and the resulting linear movement is converted to rotation, via the one-way clutch, of the drive shaft. The load may be provided by waves or vehicle motion.

A buoyant hydrodynamic pump is disclosed that can float on a surface of a body of water over which waves tend to pass. Embodiments incorporate an open-bottomed tube with a constriction. The tube partially encloses a substantial volume of water with which the tubes constriction interacts, creating and/or amplifying fluid-flow oscillations therein in response to wave action.

Water within such a reservoir may return to the body of water via a turbine, thereby generating electrical power (making the device a wave engine), or the devices pumping action can be used for other purposes such as water circulation, propulsion, dissolved minerals extraction, or cloud seeding. Methods are disclosed for manufacture of hydrogen at sea and for delivery of said hydrogen using a ship. Methods are disclosed for filling a hydrogen-loaded carrier ship at sea.
