A harvesting system for harvesting aquatic plants in or floating on a culture medium a harvesting bed configured to be circulated in and out of the culture medium. An actuator circulates the harvesting bed, a scraper positioned against a surface of the harvesting bed scraps the aquatic plants on the harvesting bed and a channel transports the aquatic plants removed by the scraper toward a collection vat. The collection vat receives the aquatic plants transported via the channel.

Systems and methods for cleaning and/or removal of ocean garbage are provided. The system includes a cleanup autonomous vessel (CAV) for collecting garbage, an autonomous tugboat (AT) for moving a large ocean container (LC), and a sorting machine (SM) and for sorting garbage. The system may also include an autonomous boat (AB) for transferring garbage from the CAV to the SM and for supplying fuel from the AT to the CAV. The system further includes regular ocean vessels (ROV) for moving the LC to different location. The CAV, AT, AB, LC, and ROV may operate in conjunction with a bidding process.

The present disclosure is directed to providing a toothed conveyor belt type oil recovery device including: a recovery conveyor which is rotates in such a way that a continuous track rotates, the recovery conveyor having multiple teeth made of a hydrophilic material on an outer surface, the recovery conveyor having one side positioned in water in which oil is spilled to recover the oil while feeding the oil into a space between the adjacent teeth by the rotation; and a separation unit which holds an oil separating liquid, and is positioned on the other side of the recovery conveyor to separate the oil from the teeth while the oil separating liquid is fed into the space between the adjacent teeth by capillary suction when the teeth move on to the oil separating liquid on the other side of the recovery conveyor by the rotation of the recovery conveyor.

A waste management system, primarily intended to be for waste floating in water, though it can also be used on land. A shredding device will reduce the size of the particles of waste. Ocean water is removed by a drying device. The dried waste material is cryogenically frozen using liquid nitrogen or other suitable means. The frozen waste material is then pulverized and ground into a powder. The powder may then be sprayed into a gas-filled chamber and heated. Temperature, pressure and humidity are maintained within the chamber for more than one minute. Microwave or other radiation and catalysts may be used to enhance the process of extraction. The processed material is then removed from the chamber. Carbon and water may be recycled. The carbon may be used as fuel by the ship. Water may also be used by the ship or returned to the ocean in a non-toxic condition.

The invention discloses an automatic maintenance apparatus for cleanliness of river surface, which includes a processing device housing. The processing device housing is provided with a working chamber, and the working chamber is provided with a lifting mechanism. The lifting mechanism can collect garbage on the river surface. In this device, the garbage collected is simply sorted. A conveying mechanism is provided on the right side of the lifting mechanism, and a storage mechanism is provided on the lower side of the conveying mechanism. The storage mechanism includes the trapezoidal block. The storage frame between the right end surface and the right end wall of the working cavity. When there is too much waterweed in the storage frame, the device will stop working. The device is easy to operate, and the two devices are fixed at a certain position on both sides of the hull. Then, turn on the motor and start the boat.

A method of fabricating an coating includes providing a coating comprising a base material. The base material is coated with an inorganic material using at least one of an atomic layer deposition (ALD), a molecular layer deposition (MLD), or sequential infiltration synthesis (SIS) process. The SIS process includes at least one cycle of exposing the coating to a first metal precursor for a first predetermined time and a first partial pressure. The first metal precursor infiltrates at least a portion of the base material and binds with the base material. The coating is exposed to a second co-reactant precursor for a second predetermined time and a second partial pressure. The second co-reactant precursor reacts with the first metal precursor, thereby forming the inorganic material on the base material. The inorganic material infiltrating at least the portion of the base material. The inorganic material is functionalized with a material.
