A seat enclosure includes a number of seats located at the perimeter of a vehicle to form a barrier. The seat includes a base with a panel attached to the backside of the base to give the seat enclosure a finished appearance.

A structure for reducing the drag of a ship and its application thereof is provided. The structure for reducing the drag of a ship includes at least one turbulence generating structure which is installed on the side surface between the widest section and the aft end or on the bottom surface between the deepest portion and the aft end of the ship. The arrangement of the turbulence generating structure can generate turbulence to reduce the drag of the ship, and thereby increase the speed of the ship and/or reduce the ship's fuel consumption.

Example implementations include a system and method of using plastic from bodies of water and creating a floating platform by collecting plastic from a body of water, cleaning the collected plastic, melting and compacting the plastic, molding a plurality of hexagonal blocks from the compacted plastic, stacking the plurality of hexagonal blocks, wherein a system of springs and an energy storage device is provided between each of the plurality of hexagonal blocks, and coating the stacked blocks with a non-toxic material. 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 drain pot includes a body and at least one flexible catch. The body has an inlet and an outlet. The inlet and the outlet are at opposing ends of the body and in fluid communication with each other. The at least one flexible catch extends from and is disposed around the body.

An apparatus includes a marine component or structure having a surface to be exposed to a marine environment during use. A photocatalyst coating is secured to the surface of the marine structure, wherein the photocatalyst coating includes titanium oxide. The marine component or structure is preferably selected from a boat hull, dock post, dock piling, pier, and buoy. A method may be provided for reducing or preventing barnacle attachment to a marine component or structure, including forming a transparent photocatalyst coating on an external surface of the marine structure, wherein the transparent photocatalyst coating includes a titanium oxide, and placing the marine component or structure in service within a marine environment.

A curved origami-based metamaterial includes a panel of material having a plurality of curved creases each disposed within a plane of the panel. The panel is configured to be folded along one of the plurality of creases, and the panel is also configured to be bent about an axis disposed outside the plane of the panel. Stiffness manipulation is configured to be achieved in situ by activating a different one of the plurality of curved creases.

The present disclosure is directed to a personal watercraft, such as a standup paddleboard, provided with a viewing window that allows the user to view the underwater environment. The viewing window may be watertight and constructed from at least two durable, transparent panels. The area between panels may be sealed from air and water infiltration. A user may add waterproof lights to the bottom of the standup paddleboard in order to allow viewing of the underwater marine environment at night.

A seat enclosure includes a number of seats located at the perimeter of a vehicle to form a barrier. The seat includes a base with a panel attached to the backside of the base to give the seat enclosure a finished appearance.

Disclosed herein is a composite tow comprising a plurality of ceramic filaments; one or more sacrificial yarn filaments; where the sacrificial yarn filaments are operative to undergo decomposition or melting upon being subjected to an elevated temperature; and wherein the sacrificial yarn filaments leave open spaces in the tow upon being subjected to decomposition, dissolution or melting; where the filaments have an average filament diameter of 5 to 15 micrometers.
