Rotating radial blades cut thick ground ice and expel crushed ice through the frame, enabling single-pass de-icing without chemicals.

A heated upper cover and underwater heat cup keep the pond de-icer visible in snow while preventing surface freezing for aquatic life.

A floatable charging base tracks water level changes, using magnetic docking and wireless charging so the cleaner recharges without leaving the water.

A floatable magnetic charging base tracks water-level changes so a surface cleaner can dock and recharge wirelessly without removal.

Encapsulated permanent magnets and reinforcement sheets let containment booms attach quickly to ferrous structures while resisting tensile loads.

Renewable cardanol imidazolium ionic liquids modify nanoparticles to collect spills, lower crude viscosity, and improve oil recovery.

A floating sealed power unit adds water-surface debris collection to a pool robot, cutting the need for separate cleaners and improving efficiency.

A sensor-driven floating boom and catch bin captures waterway trash, then opens for boat traffic while using hydrokinetic energy.

During subsea pipeline lifting, a recovery cap captures buoyant hydrocarbons and transfers them to a reservoir to prevent marine spills.

A remotely controlled weed removal boat uses positioning, wind and visual sensing, and a mesh conveyor to work in narrow shallow waters.

Gravity-fed filtration lets water drain while retaining hydrocarbons, avoiding pump failures and excavation in leak containment.

Gravity-driven filtration lets water drain while retaining hydrocarbons, avoiding pump and sensor failures in surface spill containment.

Stacked hydrophobic polypropylene layers wick and retain surface hydrocarbons while staying buoyant and easier to recover for reuse.

A hydrophilic double bottom lets this stackable spill barge separate water at sea, store more recovered oil, and keep a constant draft in shallow waters.

Buoyancy and parallel expanders keep the net partly submerged, cutting user effort while improving single-pass debris collection.

Inflatable beams and skirts create a vortex inside the net, reducing hydrocarbon loss during high-speed single-vessel recovery.

Distributed batteries and motors across the skimmer and backpack cut carrying weight while extending continuous oil collection time.

A self-flow frame, filtration, and onboard compression automate floating waste pickup while reducing manual labor, water disturbance, fuel use, and odor.

By placing the water outlet ahead of the propeller, negative pressure boosts filter flow and fine dust capture without a pump.

A rotatable buoyant baffle closes the basket inlet during stopping or reverse motion to prevent garbage leakage and preserve cleaning performance.

An axial pipe, welded end caps, and chain stop keep an HDPE marine boom sealed, supported, and securely mounted despite cold-weather shrinkage.

Buoyant autonomous vehicles keep oil-soaked hair mats afloat for easier recovery while cleaning spills and monitoring waterways.

A sliding cover eases garbage bin removal while an offset anti-leakage baffle avoids rotor damage and improves floating debris collection.

A pivoting boom with floats, telescopic tubes, and intake channels corrals surface oil for faster marine spill recovery in rough seas.

A weighted base, suction piles, and a rotating spring-supported curtain contain deep-sea oil leaks faster while reducing spill loss and marine impact.

Rotating fishing claws lift floating debris onto a floating platform, clearing water surfaces without blocking flow or leaving waste immersed.

A chain stop, axial passage pipe, and baffle-supported HDPE shell help the boom stay watertight and retain shape despite cold-weather shrinkage.

Buoyant materials raise submerged collection boxes, reducing worker effort and enabling garbage collection by small vessels in narrow waterways.

A rotatable inlet baffle closes during stops or reverse motion, preventing garbage overflow from a water surface cleaning robot basket.

Gravity and cold-weather shrinkage can deform HDPE booms; steel reinforcement and flanged connections help maintain shape across continuous barriers.

Coextruded HDPE layers, carbon black, UV stabilizers, and fusion-welded caps help the marine boom resist cold shrinkage and deformation.
