Adapters, devices, and methods are provided that permit catalytic monolith modules to be used in catalytic converter systems designed for fixed bed catalysts using granular catalysts. The adapter provides air flow straightening upstream from the catalytic monoliths, mitigating non-uniform flow into the catalytic monoliths. The adapter is reusable, allowing simple replacement of spent catalytic monolith modules.

A pleasure craft is provided in which one or more decks of the craft have a deck construction in which a base body is provided, and in which a first part of supporting and stiffening members is arranged on an upper face of the base body, and a second part of the supporting and stiffening members is arranged on a lower face of the base body. This construction optimizes and rationalizes the arrangement of components of the installations of the craft in terms of size, weight and the required amount of space, as well as in terms of required power, this resulting in a reduction of time and cost for mounting the installations of the craft.

A system and method allows boats to operate air conditioners while positioned above the water level. A dock-mounted control unit has an inlet for lake or seawater, an inlet for fresh water, and an outlet to the raised boat. The fresh water is temporarily used to prime the system, after which the boat's A/C system can operate normally. After the system is primed, a valve on the control unit is used to close off the fresh water inlet, and the fresh water hose may be removed. A Y-valve (or two 1-way valves) provides two settings, one for ordinary, on-water operation, and the other for use in conjunction with the invention. The invention allows the boat's AC system to function as though it were in the water, allowing normal heat exchange with the body of water and thus, normal A/C while on a lift or hoist.

Sun heats dark continents more than reflective oceans. Air moves onshore from high pressure to low. Creating wind: powering weather and storms—“hurricane-in-a-box-on-water” principles producing electricity in a marine vessel, providing Green Technology for Marine Transportation. Captured and recovered heat, offset by loss of heat, creates differential pressure conditions across multiple rotary engines. Night and day, a working fluid moves from high pressure to low; powering alternators, batteries, domestics, and in-hull electric drive trains, in a unique, lightweight exoskeleton dome shell design vessel. Disclosed vessel design advantages include: high energy collection and living space to vessel length ratio; high strength to weight ratio; high carrying capacity, downwind sailing while producing electricity; modular fabrication and shipping; and sustained hull speed in a vessel harvesting energy from the environment. The longer the vessel: the more it carries: the greater the hull speed: the faster it goes.

A ventilation system is provided for persistent natural ventilation by circulation of air between an interior space and an external environment. In one example, the ventilation system includes an air intake including a domed upper cover with exterior windows which allow air to circulate through an upper chamber, a baffle around floatable elements, the baffle including an annular protective screen and valve windows, a lower chamber fluidly coupled to each of the upper chamber via the baffle and an interior duct via a main window thereof, wherein the interior duct is fluidly coupled to the interior space, and wherein the floatable elements are positioned on respective seats when no liquid is present, each of the seats spaced a distance opposite to a respective one of the valve windows. Responsive to liquid entering the upper chamber via the exterior windows, the valve windows may be automatically blocked by the floatable elements.

Disclosed is a control method of a damper of a variable-air-volume air distributor and a control system thereof, mainly comprising a volume adjusting valve for the variable-air-volume air distributor, a valve actuator, a BP neural network-based main controller, a data collector and a user operation panel. The control method thereof is to use, mainly based on the collected room temperature and static pressure at the inlet of the air distributor, the BP neural network predictive model to establish a nonlinear model of temperature & static pressure and valve opening, perform training and optimization, and optimize the output valve opening to obtain and label an optimal value as the set value of the controller to control the action of the valve actuator, thereby realizing an automatic variable air volume.
