An emitter apparatus is mounted on a marine structure powered by wind or marine hydrokinetic energy to disperse a carbon dioxide sorbent such as sodium hydroxide. The sorbent can be generated by reverse osmosis of seawater with electrolysis of the brine, or delivered from an external supply. Suitable marine structures include offshore wind turbines, marine hydrokinetic generators, offshore oil platforms, merchant vessels, and other fixed and mobile structures. Effective capture is made by dispersing a fine mist or fog of aqueous sorbent from nozzles with a particle size from a nozzle of less than 100 microns. The sorbent reacts with atmospheric carbon dioxide forming carbonates and bicarbonates, which drift and fall to the ocean surface, reducing surface acidity and capturing additional atmospheric carbon dioxide via absorption at the local ocean surface. The resulting carbonates sink to the ocean floor and are there sequestered.

A motorised outrigger stabilised watercraft comprising a main hull extending in a fore-aft direction, a single outrigger arranged to stabilise the main hull, extending substantially parallel to the main hull and spaced laterally from the main hull, and at least one hydrofoil located at or proximate the stern of the main hull.

The present invention provides a novel floating and renewable energy-powered desalination vessel, which also functions as a wind turbine generator and wave energy generator platform. With energy derived from the wind and waves, the vessel performs reverse osmosis within a vertically positioned cylindrical section extending below a buoyancy chamber. The cylindrical section contains reverse osmosis membranes located above a seawater screening and filtration system, which serve as ballast. The entire vessel and power systems are configured to have the center of mass below the center of buoyancy, forming a vertically stable floating structure with minimum pitch, roll, and wave heave in high sea states. The electric power generated is utilized internally to produce desalinated water or hydrogen from the desalinated water's electrolysis, power an onboard data center, or power delivery to a shoreside power grid. In addition to a wind turbine generator and a wave energy generator, a photovoltaic array or a marine current generator may be utilized to power these applications. Alternatively, the desalination vessel operates with the assistance of shore-based power provided by cable.

A vehicle flotation assembly includes a plurality of bladders that is each coupled to a bottom side of a vehicle. Each of the bladders is inflatable to float the vehicle when the vehicle is exposed to flood waters. A water senor is coupled to the vehicle to sense flood waters rising beneath the vehicle. A pump is coupled to the vehicle and the pump inflates each of the bladders when the pump is turned on, and the pump is turned on when the water sensor senses flood waters. A plurality of anchor actuators is each of the anchor actuators is coupled to the bottom side of the vehicle. A plurality of anchors is each lowered from the respective anchor actuator when the respective anchor actuator is actuated into a lowering condition thereby inhibiting the vehicle from being floated away by the flood waters.

A planning boat includes at least one tank provided on a bottom of the boat. The tank has, at a stern side, a wall through which a through hole is provided below a waterline. A hull of the planning boat includes a bottom plate that forms the bottom of the boat, right and left side plates that form sides of the boat and a bow, a transom plate that forms a stern, and a plurality of longitudinal vertical plates. The plurality of longitudinal vertical plates each extend between the transom plate and forward portions of the side plates along a sailing direction and each have a lower surface that is fixed to an upper surface of the bottom plate. The tank is formed by using the pair of longitudinal vertical plates of the existing planning boat.

A safety system for use with vehicles such as boats. The safety system includes one or more inflatable bags or bladders which may prevent the vehicle from sinking in a body of water. The bags may be stored in housings, and the housings may be angled to ensure smooth deployment of the bags. A pressure regulator and one or more valves may ensure the inflatable components stay inflated so as to ensure the vehicle stays afloat. The safety system may be automatically or manually activated.

A sponson attachment for an airboat allows the airboat to increase its safety and stability very quickly. A method for attaching a sponson to an airboat hull includes attaching first and second flexible tethers to a side of the sponson. The method also includes removably securing the first flexible tether to an exterior of the airboat hull adjacent a gunnel, and removably securing the second flexible tether below the first flexible tether on the exterior of the hull.
