The present disclosure provides a flotation device for ensuring that a container held within the device floats upright in water. The device is a ring with an opening to receive and securely accommodate a container. The ring is comprised of an elastic material to accommodate a variety of sizes of beverage containers and containing a plurality of buoyant inserts such that the ring forms a regular polygon shape. The ring further comprises spacers in between the buoyant inserts for ensuring that the buoyant inserts maintain approximately equidistant spacing, and the floatation device holds its regular polygon shape.

A system for collection of rainwater in the open ocean may include: (a) one or more ocean-going vessels, wherein each ocean-going vessel is configured for collection and storage of rainwater, wherein each ocean-going vessel is configured to drift with surface ocean currents in order to navigate to one or more delivery locations, wherein each delivery location is on or near to a land mass; and (b) one or more delivery stations located at the one or more delivery locations, wherein each delivery station is configured to receive stored rainwater from one or more of the ocean-going vessels.

A floating body (4) for a spar-type offshore wind power generation facility floating sideways is raised by injecting ballast water at sea, by steps including a first step of decentering a center of gravity of the floating body for the spar-type offshore wind power generation facility by means of a center-of-gravity decentering device, and a second step of injecting the ballast water to raise upright the floating body for the spar-type offshore wind power generation facility. The center-of-gravity decentering device may be a weight (2) attached to an outer surface of the floating body, or a solid ballast (34) introduced in the floating body.

The invention relates to a maritime transport system for oil and the derivatives thereof, which includes a tractor unit with a device for driving at least one floating, rotary spheroid container. The at least one container has two semi-spherical domes, an upper one and a lower one, that are closed at the base end and open at the other, the base of each containing a flat surface. Both domes are assembled with the open ends facing one another and are joined at the circular perimeter thereof by a fitting belt with securing device and a gasket, both being solidly joined together. Inside the container are disposed an upper structure and a lower structure that are solidly connected to connecting beams, defining a self-supporting cube-shaped cage with projecting rotating devices and multiple individual housing cells for at least one tank of fluid to be transported.

Methods and systems are provided for transient fluidic coupling via reversibly couplable conduits. In one example, a method includes directing a conduit assembly to a receiving port by releasing one or more fluid streams from the conduit assembly. The method may further include fluidly coupling an internal passage of the conduit assembly to the receiving port. The internal passage may extend from the conduit assembly and along a conduit between a pair of free-floating bodies, such as between a wave engine and a tanker ship, so as to exchange one or more fluids, such as an electrolysis reactant and an electrolysis product. The fluidic coupling may be reversible, in that the conduit assembly may be detached from the receiving port to sever the fluidic coupling. In certain examples, the detaching may be actuated by releasing one or more additional fluid streams from the conduit assembly.

A completely transparent spherical body is surrounded externally by a plurality of leaf plates arranged in equal spacing along a main outer ring rack of the spherical body. Two rubber tires are included to wrap the spherical body. A rider inside the spherical body pedals to rotate the spherical body forward. A vehicle having the spherical body can be autonomously operated to move on land or water, and in the air. In addition, to operate this vehicle, no specific road or environmental requirement is needed, and no other obstacle, even a traffic accident can stop its movement.
