A wave-powered floating water pump apparatus comprises a housing operatively connected to a piston capable of reciprocating therein, and an exterior float. The housing interior defines a compression chamber including a compression chamber back valve. The compression chamber back valve opens when the apparatus descends in the ocean, and closes when the float lifts the apparatus. The piston comprises a piston shaft with a piston back valve therein, constructed and arranged to permit water which enters the piston shaft in response to water pressure from the compression chamber only to exit the top of the piston shaft at a higher elevation. A floating generator system for harnessing energy from ocean waves to produce usable electrical energy may include the pump, a water storage reservoir and a hydro-turbine. A system for purifying and desalinating water may include the pump, a semi-permeable membrane for reverse osmosis and a reservoir for purified water.

An aeration device has an entrainment chamber for mixing air and water in a body of water, wherein the air becomes partially dissolved into the water, thus creating water enriched with dissolved air, and excess air that did not dissolve into the water. An air input introduces air into the aeration device and a water input introduces water into the aeration device. Water enriched with dissolved air exits a water discharge of the aeration device at a first level within the body of water. An air exhaust manifold wherein the excess air can exit the water discharge while remaining inside the aeration device, an exhaust stack that permits the excess air to travel up from the air exhaust manifold, and an exhaust that permits the excess air to exit the aeration device at a second level within or above the body of water.

The present invention is a two-part irrigation system that utilizes both groundwater and rainwater. The first system extracts water from groundwater layers by using extraction pipes filled with nanomilled sand that constantly moves water upwards through capillary action. The second is a rainwater collection and capillary irrigation system. The groundwater irrigation system consists of an external groundwater transport pipe filled with nanomilled sand. This encapsulates an empty internal transport pipe that delivers percolated water. The rainwater irrigation system consists of a collection, storage, filtration, and capillary irrigation system. Rainwater is collected by trays and a water tank, where the water is filtered through a hollow fiber membrane filter. This clean water is used as potable drinking water or for irrigation. The water volume required for irrigation is calculated based on moisture data collected by moisture detection devices. Both systems are solar powered, and are controlled and programmed by the user.

An apparatus for collecting floating marine debris comprises a frame, a debris collection container in communication with a rear opening of the frame, a pair of helicoidal screws mounted to the frame in a symmetrical V-arrangement that tapers inwardly from a front opening of the frame to the rear opening, and at least one prime mover rotationally coupled to the pair of helicoidal screws. The prime mover is operable to rotate the helicoidal screws in opposite directions at the same angular velocity in water to move the apparatus forward through the water, such that floating marine debris enters the apparatus through the front opening, passes through the rear opening and is collected in the debris collection container.

The present invention provides a novel floating and renewable energy-powered desalination vessel, which also functions as a wind turbine generator and wave energy generator platform. With energy derived from the wind and waves, the vessel performs reverse osmosis within a vertically positioned cylindrical section extending below a buoyancy chamber. The cylindrical section contains reverse osmosis membranes located above a seawater screening and filtration system, which serve as ballast. The entire vessel and power systems are configured to have the center of mass below the center of buoyancy, forming a vertically stable floating structure with minimum pitch, roll, and wave heave in high sea states. The electric power generated is utilized internally to produce desalinated water or hydrogen from the desalinated water's electrolysis, power an onboard data center, or power delivery to a shoreside power grid. In addition to a wind turbine generator and a wave energy generator, a photovoltaic array or a marine current generator may be utilized to power these applications. Alternatively, the desalination vessel operates with the assistance of shore-based power provided by cable.
