The present invention relates to a power generation apparatus, and more particularly to a power generation apparatus that generates power by dropping collected water. A power generation apparatus according to an embodiment of the present invention includes: a chamber having an accommodation space for accommodating water, and configured to accommodate water introduced through an intake pipe disposed on the bottom surface thereof; a pressure pump configured to discharge the air of the accommodation space out of the chamber through a discharge pipe provided on the ceiling surface of the chamber by generating pressure; a spray unit provided on the side surface of the chamber, and configured to spray water, introduced by the pressure pump and accommodated in the accommodation space, out of the chamber; and a power generation unit configured to generate power using the pressure of water sprayed by the spray unit.

The present invention is a hydroelectric power generating system having a siphon component, a generator component, and an electronics and control component, which produces an inflow of water caused by a vacuum initially created within the system and further aided by hydrostatic pressure. The inflow is directed to a ramp where it drives a water turbine located within the respective electrical generating system to produce electrical power.

According to some embodiments, a drum may be submerged in water and extend horizontally along a center axis between a first point on a first side of the drum and a second point on a second side of the drum opposite the first side. Three curved vanes may be attached to the drum such that the vanes, when acted upon by a water flow perpendicular to the axis, are operable to cause rotation about the axis, wherein an edge portion of each vane, located substantially opposite the drum, defines a plane substantially parallel to a plane defined by a surface of the drum located between the edge portion and the axis. An electrical generator coupled to the drum may convert rotational energy produced by the rotation about the axis into electrical energy.

A convertible pump formed of wound flexible tubing having an inlet communicating water to an outlet at an opposite end of the tubing. A paddle wheel with collapsible fins provides power to rotate the pump when in a vertical position. A planar surface of the wound tubing forms a table when pivoted on a stand to a horizontal disposition with the support surface for the stand.

A rotary pump that utilizes falling water to produce useful energy. The pump is a conduit in a spiral form mounted on an axis that is set at an angle whereby when rotated, water flows into the inlet end of the conduit and is transported to an elevation. The conduit is powered by an impeller wheel that rotates by falling water.

A screw system including a plurality of segmented blades. Each blade segment of the plurality of blade segments including a mounting portion and a vane portion. The mounting portion, having a helical length, for removably attaching the blade segment. The vane portion extending from the mounting portion along the helical length thereof. The vane portion having a front surface that is not parallel to a back surface from the mounting portion to a tip of the blade segment, along the helical length.

The mutually supporting hydropower systems includes a first hydropower system, a second hydropower system, and a third hydropower system. Each hydropower system includes a hydropower unit, a number of waterwheels, a number of hoist devices, and a number of motors respectively connected to the hoist devices. Each waterwheel engages a hoist device. The motors are electrically connected to a hydropower unit. The waterwheels and the hoist devices are driven by the impact of seawater which is also used by each hydropower unit to produce electricity. 40% of the power from the first hydropower system is used to drive its motors. 30% of the power from the second and third hydropower systems are also used to drive the motors of the first hydropower system. The motors are therefore sufficiently powered to discharge seawater.
