A water-driven turbine has an elongated endless conveyor with down and up streaming straightaways connected by travel-reversing turns. Paddles mounted on the conveyor present high resistance to waterflow on the downstream straightaway and low resistance to waterflow or the atmosphere on the upstream straightaway, the differential allowing the flow of water to continuously drive the conveyor which is connected to a power take-off shaft facilitating connection to a variety of energy-harnessing systems. The turbine can be towed, self-driven or mooring line manipulated to a flow site and is operable in unidirectional flows such as rivers and reversing flows such as tides at depths from surface to bottom. The paddles can be mounted or changed on shore, at the flow site and anywhere in between. The turbine is efficient in low and high velocity water flow, not easily damaged by floating debris, cavitation free and fish, mammal and environmentally friendly.

A water pumping system used for lifting liquids in vertical or near vertical conduits or pipes to a higher elevation at a reduced energy cost. Also, the water pumping system can be used to circulate water between upper and lower elevations to generate hydropower energy at a lower energy cost. The water pumping system includes a water pump, air blowers, an air supply chamber, a lift conduit, a return conduit, a flotation device separation chamber, a plurality of floatation devices, one or more flotation device pushers, a dehydration unit, and two water storage tanks. The lift conduit and return conduit creating a continuous loop in which the flotation devices can circulate and act as a piston in the lifting conduit to elevate the water to higher elevations with reduced energy. The floatation devices include spacer rings and spacer rods. The floatation devices are inserted inside the lift conduit and the return conduit.

Consistent kinetic energy is harvested from wind and from flowing water in streams, rivers and tidal flows using a translating large sail, foil or wing which is permitted to translate in one direction, followed by translating in the opposite direction while pushing or pulling a cable, rod, or tether which in turn turns a pulley, wheel or other device from which traditional sources of power can be generated. The pulley wheel can be used to generate electricity, create hydrogen from water by electrolysis, compress air for transmission or storage, charge batteries, or perform work such as pumping water, heating water, moving objects, etc.

A gravity and buoyancy engine producing energy via a cyclical process of harnessed gravity and buoyancy has a gravity chamber, at least one air lock chamber, at least one electricity producing system, at least one buoyant object, and at least one vertical motion transfer assembly. The gravity chamber provides a zone for the buoyant object to engage the vertical motion transfer assembly as the buoyant object descends toward the air lock chamber. The vertical motion transfer assembly further transfers kinetic energy from the vertical motion of the buoyant object to the electricity generating system in order to provide useable electrical energy. The airlock chamber subsequently reintroduces the buoyant object into the buoyancy chamber to return said buoyant object to an elevated position and recycle through the gravity chamber.

A hydro power plant for the use of a water flow includes an endless moving belt on which a plurality of blades is foldably attached. The moving belt is guided around at least two deflection points in such a way that there are two rows of blades moving in opposite directions during operation. At least one of the two rows of blades is oriented inclined to the direction of the water flow. At the deflection points, the blades are folded over from a first blade position into a second blade position and from the second blade position back into the first blade position.
