Some geographies have tide ranges above 15 yards, but most do not. The wider the tide range, the more hydroelectric power can be generated per cycle of low tide to high tide and then high tide to low tide, using a tidal barrage. Methods of raising the high tide above the measured level to fill the storage ponds to an even higher level and a method to empty the storage ponds to a lower than low tide level, provide means to expand the tide range significantly, enabling many more planet geographies to have economically feasible hydroelectric power.

A gear pump for power generation comprises a first rotor and a second rotor in a case. The first rotor comprises a first plurality of radially spaced teeth, wherein the first plurality of radially spaced teeth wrap around the first rotor helically in a clockwise direction, and wherein at a first position the first plurality of radially spaced teeth have a helix angle different than the helix angle of the first plurality of radially spaced teeth at a second position. The second rotor comprises a second plurality of radially spaced teeth, wherein the second plurality of radially spaced teeth wrap around the second rotor helically in a counter-clockwise direction, and wherein at a first position the second plurality of radially spaced teeth have a helix angle different than the helix angle of the second plurality of radially spaced teeth at a second position.

The invention is directed to a device and to a method for utilizing groundwater, comprising two wells whose well water levels are at different elevations, a connecting line between the well water reservoirs of the two wells, a hydraulic motor, or a pump that is operable as a generator, inside the connecting line, and an electrical generator that is mechanically coupled to the hydraulic motor or to the pump that is operable as a generator.

A system for generating hydrokinetic power from a subcritical channel is disclosed. The system comprises a power channel diverted from the subcritical channel for generating hydrokinetic power by changing one more flow parameters of water, wherein the power channel includes an intake section, one or more slope section, one or more power section and a recovery section, an intake spillway at the intake section of power channel, connecting the subcritical channel with the power channel for enhancing the velocity of water, wherein the intake spillway is designed based on rate of discharge of water to be drawn from the subcritical channel and an array of turbines located in the power channel for generating power using the diverted water from the subcritical channel, wherein the number of turbines are based on the length of the power channel.

A hydroelectric power generation system using channel for water supply includes a water guidance unit, a one-way gate, and a plurality of power generation units. The water guidance unit includes a channel for water input, with an entrance provided in front of the channel for connection with a water source. The water entering the channel passes through the one-way gate and is prevented from flowing back to toward the entrance, so as to be effectively accumulated. When the water in the water guidance unit reaches the predetermined water level, the power generation units around the water guidance unit conducts power generation with the water, thereby improving the power generation effectiveness.

An improved method of lifting fluid using the difference between atmospheric or higher boosted pressure and fluid vapor or vacuum pressure applied to a series of chambers with a movable plate that divides each into variable volumes, and comprises one stage of the system. Combinations of pressures in the chambers between the movable plates lift the fluid to a height where the fluid column base pressure equals atmospheric or boosted pressure less friction and mass losses. A vertical array of stages, each lifting fluid from the stage below it, allows fluid to be lifted to any height, limited only by structure or geographic elevation. Further; operating pressures are tapped from the top and bottom of a standpipe filled with static fluid, pressure changes are made when the volumes are zero, and the sum of the volume receiving fluid and volume delivering the fluid are constant, making the system closed. Once raised, the fluid may be released for it's end use and more particularly; through a power generator. Where the fluid is water in an open environment and fed through a turbine, the water may be returned to the system reservoir to be reused in the cycle or if in a closed system the fluid may be returned to a chamber under pressure for reuse.
