A coastal recovery module including a body portion defining an interior compartment. The coastal recovery module may also include a selectively sealable fluid conduit. The selectively sealable fluid conduit may provide a fluid communication between the interior compartment and an exterior of the body portion, the fluid conduit configured for selectively flooding and dewatering the interior compartment. The coastal recovery module may further include a wave energy mitigation structure associated with at least a portion of a top surface of the body portion.

A transparent solar heat absorbing apparatus includes a transparent member allowing sunlight to pass through, a wavelength selective member disposed beneath the transparent member, a heating tank formed between the transparent member and the wavelength selective member. The wavelength selective member allows light in a transmission range including at least a visible wavelength range to pass through and reflects light in a reflection range including at least an infrared wavelength range. At least one of the transparent member and the wavelength selective member has a waveform structure on at least one of its upper surface and bottom surface.

The invention relates to an aquaculture facility applicable to open sea areas where waves are huge and flow is rapid as well as a method. The facility comprises culture containers, floating bodies, a hanging rope, a main rope, a seedling rope, weight stones, a cable, an anchor, a signal rope and signal drifts, wherein, the floating body is tied to the upper end of the culture container, and the lower end of the culture container is tied to the main rope through the hanging rope, so that the culture container is positioned above the main rope; the distance that the main rope and the culture containers are away from the sea floor can be adjusted by adjusting the lengths of the seedling rope and the cable ; the signal shifts float on the water surface and are connected with two ends of the main ropes through the signal rope; and when the facility is operated, the main rope is pulled out of the water surface through the signal rope, the culture containers are cast with bait and harvested one by one along the main rope, or the culture depth is regulated. The facility and the method have the advantages that the culture containers can be protected from the influences of wind and waves on sea water, damages to cultured organisms and the facility by bad weather are avoided, cultured organisms can be farmed in clean outer lakes where water layer is the most proper and water flow is unobstructed as well as open sea areas around islands, the culture containers suspend, the weight of the facility is reduced, and the labor intensity is reduced. The facility is applicable to abalone culture and to culture of fixed type aquatic animals and plants (such as oyster and kelp) or aquatic animals and plants which have a certain attachment ability (such as sea cucumber).

An outdrive for a marine vessel, such as a watercraft having an inboard engine, is provided. The outdrive can include an upper drive unit having a driveshaft that rotates in response to rotation of an input shaft coupled to an engine within a hull of the watercraft. The upper drive unit is movably joined with a lower drive unit, which includes a propeller shaft that rotates in response to rotation of the driveshaft, and an associated propeller. The lower drive unit is movable from a raised mode, in which it is adjacent the upper drive unit, to a lowered mode, in which it is a preselected distance from the upper drive unit, thereby lowering a thrust point produced by the propeller, all while the watercraft is moving through water and while the propeller is producing thrust. A related method and outdrive upper unit are also provided.

The invention discloses a vehicle passive safety auxiliary device and a use method thereof. The vehicle passive safety auxiliary device comprises a central unit, a vehicle-mounted bus network, an emergency button, a vehicle-mounted power supply, an interaction module and six intelligent gas bag boxes. The intelligent gas bag boxes are arranged on a vehicle and connected with the central unit. The vehicle-mounted bus network, the emergency button, the vehicle-mounted power supply and the interaction power supply are electrically connected with the central unit. Each intelligent gas bag box comprises a shell, wherein a first radio frequency module, a second self-contained power pack, a gas generator, a gas bag, a gas bag opening sensor, a water pressure sensor and a second processing module are arranged in the shell, the gas bag opening sensor is connected with the gas bag, and the first radio frequency module, the second self-contained power pack, the gas generator, the gas bag opening sensor, the water pressure sensor and the second processing module are electrically connected. The vehicle passive safety auxiliary device is strong in flexibility, convenient and rapid to install, replace and maintain and high in user-friendly degree, a passive safety concept is fused in the vehicle passive safety auxiliary device, and the vehicle passive safety auxiliary device has large application market in places nearby seas, lakes and rivers and places where heavy rainfall easily happens.
