An underwater device for water power conversion includes multiple cups, each cup constituted by a bottomless cup member and a bottom plate fitted pivotally in a freely rotatable manner, wherein the bottomless cup member blocks flowing water in a standing state and makes flowing water pass through in a lying down state, generating flowing water resistance difference between the two states. The cups are installed in a continuous member of a waterwheel submerged in flowing water so that the cup stands in a forward advance path and lies down in a reverse advance path. A water blocking plate is also provided in the reverse advance path so as to utilize centrifugal force to turn the bottomless cup member from the lying down state to the standing state, thereby making the cup turn or circulate continuously in flowing water.

A system includes a lower trough, an upper trough, and a float tube in fluid communication with the lower trough. The system includes a track extending from a first location proximate the second end of the float tube to a second location proximate the first end of the float tube and a trolley configured to travel along the track from the first location to the second location, selectively engage a canister when the trolley is in the first location, carry the canister along the track from the first location to the second location, and selectively disengage the canister to deposit the canister into the lower trough, wherein movement of the trolley along the track exerts a force on an electrical generator to cause the electrical generator to generate electrical energy.

A water motor which includes a tubular tipping lever arm open on both ends and a central water fill port, and a central fulcrum pivotally supporting the tipping lever arm for seesaw tipping thereabout. Temporary containment vessels are provided on opposite ends of a work lever arm and positioned under each open end of the tipping lever arm to receive water flowing from a respective one of the open ends of the tipping lever arm. A drain valve is provided in each container for respectively draining water from the containers and the drain valves are respectively opened when a respective one of the containers is in a minimum height position. A directional flow control lever depends downwardly from the tipping lever arm and protrudes between spaced lever control stops which cyclically engage and reverse the seesaw tipping of the tipping lever arm and also provides resultant draining of a respective of the containers with the push rod engagement force of the lever control stops.

An energy generating system includes a dam in an estuary defining a water containment area. The dam includes a plurality of dam elements, each including a plurality of dam panels hingedly connected in series, which are urgeable from an inoperative folded state in a chamber to an operative state by a corresponding pair of main or secondary buoyancy tanks as the tide rises and falls. Each pair of main buoyancy tanks with the corresponding dam element defines a water race within which a water wheel is located. The water wheels are mounted on corresponding drive shafts which are connected in series and which are rotatably carried on support frameworks which are supported on the main buoyancy tanks. Electricity generators are supported on carrier frameworks which are supported on the secondary buoyancy tanks at respective ends of the dam, and are driven by the adjacent one of the drive shafts.

A hydrodynamic power generation assembly and method of use therefor for generating electrical power from the combination of kinetic energy, hydrostatic energy, and turbulent energy of water. The power generation assembly comprises a water accelerator assembly comprising a support structure which is at least partially buoyant and a baffle panel member (or an array of baffle panel members) having an opening, inter-panel spacing, or flow passageway around the baffle panel(s). A hydropower converter is supported from, by, or on the support structure and is operatively coupled to a generator. The hydropower converter is positioned behind baffle assembly. Water flowing through or around the baffle assembly has an increased velocity relative the ambient current and therefore is capable of generating more power relative to the ambient water where power generation assembly is deployed. Particular types of hydropower converters suitable for use with the invention are turbines and water wheels.
