An autonomous vessel and method for transporting a cargo from an origin to a destination utilizing water currents, a satellite location system, and a satellite communication system includes a hull for navigating a body of water. A communication module is adapted for wireless communication with local contacts and the satellite communication system. A propulsion module is adapted to propel the hull through the body of water and preferably includes one or more relatively low-power electric motors. A navigation module is adapted to steer the hull towards a next waypoint. The navigation module preferably includes a rudder control system and is connected with a location module that is itself adapted for communication with the satellite location system to find a current location of the hull on the body of water. A controller is adapted for controlling the modules, sending information, and for receiving commands and information.

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 tube's constriction interacts, creating and/or amplifying fluid-flow oscillations therein in response to wave action. Wave-driven oscillations result in periodic upward ejections of portions of the water inside the tube that can be collected in a reservoir that is at least partially positioned above the mean water level of the body of water, or pressurized by compressed air or gas, or both. 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 device's 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.

A buoyant hydrodynamic pump is disclosed that can float on a surface of a body of water. Wave-driven oscillations result in periodic upward ejections of water inside a downwardly projecting tube that can be collected in a reservoir. Water within such a reservoir may return to the body of water via a turbine, thereby generating electrical power, or the device's pumping action can be used for other purposes such as water circulation, propulsion, dissolved minerals extraction, or cloud seeding.
