The present invention relates to systems and methods for pumping or removing a fluid from a region within or on top of or in contact with a water or liquid body and applications for said systems and methods. Some embodiments may be applicable to, for example, inhibiting or preventing growth formation or fouling of structures in liquid environments. Other embodiments may be applicable to, for example, an energy storage device or a tidal power energy generation system.

The present invention relates to systems and methods for pumping or removing a fluid from a region within or on top of or in contact with a water or liquid body and applications for said systems and methods. Some embodiments may be applicable to, for example, inhibiting or preventing growth formation or fouling of structures in liquid environments. Other embodiments may be applicable to, for example, an energy storage device or a tidal power energy generation system.

Methods, systems and apparatuses including systems and methods that can be used for operating a water turbine such as along one or more flow channels of a tidal estuary for power generation is disclosed. The water turbine can be positioned within the one or more flow channels and can be turned by the flow of the water from the estuary.

There is a desire to be able to generate electrical power from the tides without turbines posing an unacceptable hazard to sea traffic and/or life, and in particular without causing such sea traffic and/or life to alter their behaviour in response to the placement of turbines and/or other structures. According to the present invention, a tunnel (7) is provided at a height substantially between the low tide height and high tide height; a power take-off system (11) is configured to convert movement of water in the tunnel into usable energy. In this way, a tunnel inlet (5) may be placed at a location that does not interfere with shipping and/or the natural environment.

Wave-power plant where the waves are guiding water into a basin, and where power is produced when water flows back into the sea through a turbine. The basin exhibits a bottom (4) positioned at least several typical wave heights down into the water, a rear wall (3), two side walls (2), a front wall (1) fronting the waves, and for larger plants, at least one partition wall (5) dividing the basins into several smaller basins. The front wall (1) and one or more division walls (5) are covered by apertures provided with check-valves (6) to allow through flow toward rear basin (14) providing water to at least one turbine (8). The basin can rest with its bottom (4) directly upon the seabed (13), and in deeper waters, above the seabed with the bottom (4) of the basin also being covered by apertures exhibiting check valves (6) for flow into the basin.

By Using the above two methods with the same principals but different methods and apparatus for rotating electricity generators shafts or pressurizing fluids using the weight of the tidal body of water using Moving Tanks, reservoirs channels A & B for high and low tide separated from sea using digital gates fill the channel A and close when tide level falls, Similarly channel B gate open and empty to the sea at lowest level, Electricity Station between the channels and the Containers replenished with water from high tide reservoir (will be held until full using counterweights), then falls and empty into the low tide reservoir which make the green energy station very much in demand due to its low cost

An electrical generation system based on tidal flow includes a reservoir and a fluid inlet tube extending between a tidal source and the reservoir. The inlet tube has at least one inlet turbine generator disposed therein. The fluid inlet tube extends along a first level. A fluid outlet tube extends between the reservoir and the tidal source. The fluid outlet tube has at least one outlet turbine generator disposed therein. The fluid outlet tube extends along a second level vertically lower than the first level. During high tide at the tidal source, tidal fluid flows from the tidal source, into the fluid inlet tube, past the at least one inlet turbine generator, and into the reservoir and during a low tide at the tidal source, the tidal fluid flows from the reservoir, into the fluid outlet tube, past the at least one outlet turbine generator, and to the tidal source.

A system comprising a tunnel implement for immersion in a moving mass. Energy from the moving mass passing through said tunnel implement is converted to rotational force. A collector device is provided having open and collapsed states, wherein the open state resists the moving mass. A rotational converting device converts the rotational force to constant singular direction. An input shaft is turned bidirectionally by the rotational force and two gears driven by the input shaft in opposite rotational directions, the gears separately attached to idler gears causing output gears attached to the idler gears to engage an output shaft in a same rotational direction. A bidirectional drive motor device drives a pulley device in a predetermined direction. A sensor device senses the position of the collector device. A trigger device is configured to activate said sensor device to indicate the collector device position and state, whether opened or collapsed.

An energy conversion device for converting water energy, in some cases water energy from waves and/or a flow such as an ocean current, into electric energy, comprises at least one rotor having a rotor rotational axis, the alignment of which is in some cases fixed by a supporting frame, and a flow housing which comprises a rotor shell which surrounds the rotor radially to the rotor rotational axis.
