Sun heats dark continents more than reflective oceans. Air moves onshore from high pressure to low. Creating wind: powering weather and storms - “hurricane-in-a-box-on-water” principles producing electricity in a marine vessel, providing Green Technology for Marine Transportation. Captured and recovered heat, offset by loss of heat, creates differential pressure conditions across multiple rotary engines. Night and day, a working fluid moves from high pressure to low; powering alternators, batteries, domestics, and in-hull electric drive trains, in a unique, lightweight exoskeleton dome shell design vessel. Disclosed vessel design advantages include: high energy collection and living space to vessel length ratio; high strength to weight ratio; high carrying capacity, downwind sailing while producing electricity; modular fabrication and shipping; and sustained hull speed in a vessel harvesting energy from the environment. The longer the vessel: the more it carries: the greater the hull speed: the faster it goes.

The present disclosure belongs to the technical field of power generators, and in particular relates to a marine support column structure with power generation function. The support column structure solves technical problems that existing marine power generators can only generate power with single energy and have few functions and so on. The marine support column structure with power generation function includes a column body. The support column structure of the present disclosure is capable of generating power with sea wind and waves, and is further capable of serving as a guardrail.

A vehicle-based airborne wind turbine system having an aerial wing, a plurality of rotors each having a plurality of rotatable blades positioned on the aerial wing, an electrically conductive tether secured to the aerial wing and secured to a ground station positioned on a vehicle, wherein the aerial wing is adapted to receive electrical power from the vehicle that is delivered to the aerial wing through the electrically conductive tether; wherein the aerial wing is adapted to operate in a flying mode to harness wind energy to provide a first pulling force through the tether to pull the vehicle; and wherein the aerial wing is also adapted to operate in a powered flying mode wherein the rotors may be powered so that the turbine blades serve as thrust-generating propellers to provide a second pulling force through the tether to pull the vehicle.

A system for recharging power storage devices on a watercraft is disclosed herein. The system for recharging power storage devices on a watercraft includes a shell, at least one linear channel fixedly mounted inside the shell, a turbine having at least one rotor, one shaft connected to the rotor, and a generator. The system for recharging power storage devices on a watercraft is useful for converting the rotational energy provided by the water flowing past the turbine rotor into electrical energy to charge a power storage device on a watercraft.

Power generators may be used to provide power to data center facility. Waterborne data center facility may prove helpful in areas following natural disasters or for military purposes where data center services are needed but not readily available.

The object of the invention is a method and an apparatus in an electric propulsion arrangement of a sailing vessel, wherein the sailing vessel has a traction device provided with an electric motor and with a propeller mechanism, the electric motor of traction device is arranged to be used, if necessary, in forward drive and reverse drive as well as during sailing as a generator for charging the accumulators of the sailing vessel. The propeller mechanism comprises a propeller hub with blades, a hollow propeller shaft fixed at its first end to the propeller hub, a shaft controlling the pitch angles of the propeller blades, said control shaft rotating inside the propeller shaft, and a servomotor rotating the control shaft. The servomotor is fixed to the second end of the propeller shaft to be rotatable along with the propeller shaft.

An enhanced system and various methods for safe and convenient deployment and retraction of boat fenders, comprising a system for stowing a boat fender in a fender receptacle, the receptacle having an opening for threading through a line, the line being attached to the fender, the line operable to pull up the fender into the receptacle through a second opening at the bottom of the receptacle, the receptacle being located within the rail, hull, or attached thereto, and being attached to a hinge, operated either mechanically or manually, to enable unobstructed deployment of the fenders.

A ship breaking down arrangement (1) comprising,—two waterborne platforms (10, 20) having at least one removing means (60) for removing dismantled parts and/or fluids from a ship (40) which shall be broken;—a midsection (30) placed between and connected to said platforms lifting means provided on the platforms for lifting and lowering the ship between said platforms; and—at least one transporting means (90) for receiving and transporting said dismantled parts and/or fluids to a receiving location, wherein breaking down is performed while the ship is still located at sea. The application also relates to a method for breaking down ships.

A catamaran lifting apparatus is disclosed for lifting objects in a marine environment. The apparatus includes first and second vessels that are spaced apart during use. A first frame spans between the vessels. A second frame spans between the vessels. The frames are spaced apart and connected to the vessels in a configuration that spaces the vessels apart. The first frame connects to the first vessel with a universal joint and to the second vessel with a hinged connection. The second frame connects to the second vessel with a universal joint and to the first vessel with a hinged or pinned connection. Each of the frames provides a space under the frame and in between the barges that enables a package to be lifted and/or a marine vessel to be positioned in between the barges and under the frames. In this fashion, an object that has been salvaged from the seabed can be placed upon the marine vessel that is positioned in between the barges and under the frames.
