In accordance with the present invention, a portable wave-swash & coastal-wind energy harvester, placed on a sea coast in swash zone captures energy contained in coastal waves and in coastal-wind through the utilization of wave turbines, wind turbines, and wave floats. Wave-float levers carrying wave floats and wave turbines, swing and maintain lower halves of wave turbines below water always. A gear system with one-way clutches transmits torque to an alternator to generate electricity. Flywheels maintain steady rotation of alternator shaft. A buoyancy chamber at the bottom produces reduction of weight of the unit when buoyancy chamber is emptied of water, and thereby enhances maneuverability of unit in water. Stabilization tanks at the top when filled with water provide extra weight and stability of the unit in its operating location. Units linked together in an energy farm combine their energy while forming a seawall-like barrier offering protection against coastal erosion.

An air conditioning system for tropical and sub-tropical island sea coast environments having access to deep ocean sea water. Sea water from depths of at least about 1200 feet, at a temperature of 47° F. or lower, is utilized as a source for circulating chilled water loops providing district wide air conditioning, in some instances with assistance from electrically driven chillers. The sea water is then further used to condense working fluid in a low temperature Organic Rankine Cycle or Kalina Cycle turbine generator, the heat source for which is the cooling jacket of a diesel engine generator, and also to condense working fluid in a steam driven Rankine Cycle turbine generator, the heat source for which is exhaust heat from the diesel engine. Alternate heat sources, if available, can be utilized. Additional electrical generation from these sources far exceeds the costs of pumping the sea water.

The invention provides a soil and ecological control method for coastal beaches, which comprises the following steps: digging water pouring blind ditches on lands to be reclaimed, spreading a water permeable anticorrosion material in the water pouring blink ditches, filling broken stones, wrapping the broken stones with the water permeable anticorrosion material, backfilling the soil of the ditches, spreading a blending material on the surface of the reclaimed lands, and uniformly blending the blending material and soil; digging tree wells, making tree foot water pouring ditches, spreading small broken stones on the bottom of the wells, laying coarse sand and fertilizer above the small broken stones, putting seedlings in the tree wells, and backfilling soil; and making ridges on the prepared land, watering manually or waiting for natural rainfall. The method has the advantages that: the soil remediation and seedling planting are performed at the same time; the greening speed is high; the survival rate of the seedlings is high; the storage rate is high; and the cost required is low. Thus, the method is suitable for large-scale virescence rebuilding of coastal beaches.

The invention discloses ecological restoration methods for difficult-standing low-efficiency wind break forests and particularly relates to an ecological restoration method for a low-efficiency wind break forest of a coastal hill ridge of East Zhejiang province. According to the method, by using the characteristic that overgrown evergreen broad-leaved tree species is dense in tree crown, the overgrown evergreen broad-leaved tree species provides shading and wind shelter for undergrown young trees, and thus, an uneven-aged multi-layer crossed colony with complete structure and efficient windproof function, which takes an objective function species as a main body ingredient, is rapidly built; and through the measures of thinning, objective function wood replanting, tending of woods, later-stage management and the like, the regional windproof objective function species can rapidly settle and grow, so that the stand structure, species configuration and site conditions are improved, a positive succession process of stands is promoted, and ecosystem service functions such as wind proofing are remarkably improved. Compared with the existing traditional technologies, the method has the advantages of easiness in building, small investment, high restoration speed, high colony structure layer, high biomass accumulation speed and superior wind breaking performance and has a broad application prospect in the ecological restoration of the difficult-standing low-efficiency wind break forests of coastal hills of the East Zhejiang province.

The present invention relates to a device useful as a controllable variable speed thruster-driven oceanographic profiler for coastal waters for measuring the vertical structure of chosen properties of the oceanic water column.

The invention provides water bulk cargo transporting equipment applicable to coastal water areas and south areas of China. The water bulk cargo transporting equipment is a ship comprising a stem, a midship part of a ship body, a stern and a cargo space, wherein the ship includes length between vertical lines, molded breadth and moulded depth; and the product of sum of the length between the vertical lines and the molded breadth is 405 to 450 times of the moulded depth. The water bulk cargo transporting equipment is a shallow-draft ship applicable to coastal water areas, so that the loss for detention of the ship due to the influence from tidewater during leaving a port can be reduced; the water bulk cargo transporting equipment adopts straight stem to replace a bulbous stem of common ship, so that the difficulty in the construction of manufacture can be reduced; and with the curved surface on the appearance, the water bulk cargo transporting equipment can reduce the wave-making resistance of the ship.
