A set of connectors for modular support platforms is provided. The connectors are used to aggregate at least two support elements, forming a support platform which can be rearranged by adding new support elements and connectors. The set of connectors is used to form a modular support platform for a solar panel power plant, allowing its installation in water surfaces.

A floating module for modular solar panel platforms having two separate components mounted, a structural component that is a rigid component and a buoyancy component that is a flexible component allowing for a more compact and simple solution all-around. The floating module allows for a technologically more advanced floating component, easier to produce, transport and deploy than most currently available solutions.

A wave energy converter (1) has: a buoyant structure (2) which, in use, floats on water; a generator (18); a generator drive mechanism (38) on board the buoyant structure (2), the generator drive mechanism (38) having an rotational input drive shaft (20) and a rotational output drive shaft (36); a drive member (22) operably connected to the input drive shaft (20), the drive member (22) being moveable back and forth between a first position and a second position; a biasing arrangement (23, 26) for example a buoyant block acting on the drive member; and, a submerged element 4, 4 which, in use, moves below the surface of the water out of phase with the buoyant structure (2), the drive member (22) being attached by a tether (28) to the submerged element (4). In use, when the buoyant structure (2) encounters a wave crest, the spacing between the buoyant structure (2) and the submerged element (4, 4) increases and the drive member (22) is pulled towards the second position by the tether (28), and, when the buoyant structure (2) encounters a wave trough, the spacing between the buoyant structure (2) and the submerged element (4, 4) decreases and the drive member (22) is urged towards the first position by the biasing arrangement (23, 26). The back and forth movement of the drive member (22) between the first and second positions causes the input drive shaft (20) to rotate and, thereby, causes the output drive shaft (36) to rotate. The submerged element (4, 4) is preferably a heave plate. The invention also comprises a heave plate for a submerged, partly submerged or floating structure.

Present invention provides a float capable of suppressing deformation of the synthetic resin body even if internal gas expands and contracts due to environmental temperature change.

A float 10 comprises a float body 20 made of a synthetic resin molded in a hollow shape, a projecting portion 202 projecting from the upper surface of the float body 20 and having a vent hole 201, and a microporous membrane 203 adhered to the outside of the vent hole 201.
