Through the use of various onboard functionalities, energy may be generated to regulate temperature and provide electricity, oxygen may be supplied, and water may be purified.

A method of assembling a pipe on a water-supported floating platform is provided. The platform includes an open central bay, and a gantry on the platform is arranged so as to surround at least a portion of the bay. The method includes providing a pipe intake assembly and staves on the platform; transferring the pipe intake assembly to the interior space of the bay; assembling the individual staves on the pipe intake assembly in an offset construction; lowering the pipe portion within the bay and into the water until the upper ends of the staves reside within a lower portion of the gantry; increasing the length of the pipe portion by assembling additional staves to the upper ends of the assembled staves; and repeating the step of increasing the length of the portion of the pipe until the pipe has a desired length.

A floatable energy platform including a buoyant structure capable of floating on water, at least one source of renewable energy carried by the structure, and power transfer equipment capable of recharging at least one type of electric-powered vehicle. Modular platforms can be readily transported and interconnected to provide different energy generation and storage capabilities.

A device for extracting energy from flowing fluid is provided. First and second buoyant lateral side members are provided. A fluid turbine is disposed between and below the lateral side members. At least one support extends from each side member to the turbine. At least one adjustable length support connects to the first and second side members, the at least one adjustable length support being adjustable between a minimum length and a maximum length. When a length of the adjustable length support adjusts toward the minimum length the first and second side members move closer together to thereby lower the turbine relative to the lateral side members. When the length of the at least one adjustable length support adjusts toward the maximum length the first and second side members move away from each other to thereby raise the turbine relative to the lateral side members.

[Problem] To efficiently transport an energy source such as electricity to any reception facility without using a power transmission cable.

[Solution] An energy transport system 100 comprises: a transport ship 10 that is equipped with holding means for an energy source; a supply facility 20 that supplies the energy source to the holding means of the transport ship 10; and a reception facility 30 that receives the energy source supplied from the holding means of the transport ship 10. Examples of the energy source held in the holding means of the transport ship 10 include electricity and hydrogen.

A floating dam or island is provided by pre-fabricating modular hollow bodies. A first group of modular bodies is laid floating on a water surface, positioning the modular bodies in mutual side-to-side arrangement so as to delimit therebetween intermediate gaps within which the reinforcing rods are protruding. A first concrete casting is performed into the gaps and over the modular bodies so as to render them mutually joined. A second group of modular bodies is then laid over the first group and a second concrete casting is performed in order to join the first and second group together. Additional groups of modular bodies are laid and further concrete castings are performed up to obtaining a monolithic block having a desired floating dam or island configuration.

A system includes a vehicle having a body and a power generation system. The power generation system includes first and second tanks each configured to receive and store a refrigerant under pressure. The power generation system also includes at least one generator configured to generate electrical power based on a flow of the refrigerant between the tanks. The first tank is configured to be cooled by one of ambient air and water to a lower temperature, and the second tank is configured to be warmed by another of the ambient air and the water to a higher temperature. The first tank or associated heat exchanger can be positioned such that the first tank is above the water's surface when a portion of the body breaches the surface. The second tank or associated heat exchanger can be positioned such that the second tank is below the water's surface when a portion of the body breaches the surface.

The invention relates to a sail having a variable profile. The sail can vary between a folded non-operative position and an unfolded operative position, wherein they determine the profile of the sail (2) and therefore the aerodynamic surface for contacting with the wind, characterised in that the sail comprises at least one sail element (24) which is inflatable and stiffenable, and which can be actuated by inflation (30) and stiffening means (29), between a folded position corresponding to said folded non-operative position and said unfolded operative position, in which the sail (2) is inflated. The profile of the sail is divided into sections (21, 22) on both sides of a shaft (20), and comprises a support structure (23) on which said inflatable sail elements (24) are disposed, said inflatable sail elements being formed by inflatable pockets (24) which can be actuated by said inflation (30) and stiffening means (29).

An offshore compressed air energy storage system has a barge comprising with a deck, and at least one pressure vessel configured to store compressed air. A power source powers at least one air compressor configured to pressurize the pressure vessel. A compander set has at least one turboexpander having an input, an output, and a shaft, as well as at least one heat exchanger and at least one turbocompressor. A mass air control valve is configured to control the compressed air flow from the pressure vessel to the turboexpander. A generator is in communication with the shaft of the turboexpander, and a control system. The at least one pressure vessel is buoyant, and wherein the at least one air compressor, the turboexpander, the mass air control valve, and the generator are attached to the barge.
