Provided is a device and method of cleaning a solar panel of a solar boat using, as cleaning water, water externally introduced and compressed during operation of the solar boat. The device includes a water inlet port disposed on the front side of the solar boat, a filtration unit removing impurities from water introduced through the water inlet port during operation of the solar boat, a compression unit compressing impurities-removed water, and a spray nozzle spraying the compressed water to the solar panel.

A turbine comprises a shaft (20), a mass (10) eccentrically mounted for rotation about shaft (20), having its center of gravity at a distance from the shaft (20) and a motion base (15). Motion base (15) rigidly supports the shaft (20), and is configured for moving the shaft (20) in any direction of at least two degrees of movement freedom, except for heave. A floating vessel-turbine (120), encloses entirely the eccentrically rotating mass (10) and the motion base (15). The turbine converts ocean wave energy into useful energy, very efficiently.

A system and method of providing, assembling and maintaining floating rows and/or arrays of photovoltaic solar panels and terrestrial or elevated based rows and/or arrays of photovoltaic solar panels.

A width-adjustable packaging bag shaper, a bag maker, a packaging machine, and a method. The packaging machine including the bag maker, a traction device and a heat sealing device are respectively arranged above the bag maker, and a width adjustment device adjusts the distances between different sub bottom plates in a front bottom plate and a rear bottom plate by using a leadscrew and slide block mechanism, and then adjusts the width of a bottom plate. The leadscrew and slide block mechanism is used as the width adjustment device of the automatic width-adjustable noodle packaging bag shaper system, and four bottom plates are respectively fixed to the width adjustment device, so the leadscrew and slide block mechanism in operation is accurate in range of adjustment, is suitable for various widths of packaging bags, and has very important significance for the three-dimensional shaping effect of the packaging bags.

The present invention relates to an apparatus and method for the localized capture, storage and specialized use of power generated from natural sources, such as solar power or hydropower. The apparatus can be used, for example, or in or near commercial or residential buildings, vehicles, marine vessels, a wind farm turbine tower, or in a solar park or photovoltaic power station, or anywhere there is a requirement for localized power generation, localized storage and wider distribution of power.

A module for a towable sonar apparatus, comprising: a core component, comprising at least one sensor and a first connection part; a casing, comprising: a tubular member provided around the core component; a second connection part detachably connected to the first connection part of the core component.

Methods, systems, and computer-readable media that implement autonomous seagoing power replenishment watercraft. An example system includes a plurality of marine vessels; a plurality of watercraft, each watercraft of the plurality of watercraft including a rechargeable electrical power supply and being configured to operate in: a first mode in which the watercraft awaits an assignment to provide electrical energy to a marine vessel of the plurality of marine vessels; a second mode in which the watercraft performs operations including keeping station with an assigned marine vessel and providing electrical energy to the assigned marine vessel from the power supply; and a third mode in which the watercraft recharges the power supply from a charging station. The system includes a controller configured to perform operations comprising: transmitting, to a first watercraft, an instruction indicating an assignment of the first watercraft to provide electrical energy to a first marine vessel.

A deep-sea multi-energy integrated platform for complementary power generation, production, living and exploration includes a platform body and a sustainable power supply system, where the platform body includes a column cabin, an upper platform housing, a lower platform housing and a current guide column; the column cabin, the current guide column, the lower platform housing and the upper platform housing are mutually connected to form a triangular platform with a hollow cavity, and a net is disposed in the hollow cavity to form a mariculture zone; the sustainable power supply system includes a wind-driven generator disposed at an end of a top surface of the upper platform housing, a solar panel disposed above a middle portion of the top surface of the upper platform housing, a wave power generation apparatus disposed on the current guide column, and several tidal current power generation apparatuses.

A floating solar photovoltaic array having an energy management power control system configured to send power clipped by an inverter to the at least one powered accessory device which can be an aerator, a diffuser, a sub-surface agitator, a sub-surface water circulator, a sub-surface positioning/mooring system, a water quality sensor; a panel washer, or a bird removal system. The array has inflatable pontoons and an air manifold system which is powered by the solar photovoltaic modules can be used to adjust the angle of inclination of the solar photovoltaic modules to the sun. The powered accessories can also be powered by unclipped power or on-shore power or combinations thereof which can be controllably adjusted by the energy management control system over time.
