A hydroelectric energy system includes a stator including a first plurality of electricity-generating elements. The system also includes a rotor including a second plurality of electricity-generating elements. The rotor is disposed radially outward of an outer circumferential surface of the stator and is configured to rotate around the stator about an axis of rotation. The rotor is a flexible belt structure having a variable thickness and extending along a portion of an axial length of the stator. The system further includes at least one hydrodynamic bearing mechanism configured to support the rotor relative to the stator during rotation of the rotor around the stator. The at least one hydrodynamic bearing mechanism includes a bearing surface made of wood or a composite material.

This invention has to do with generating electricity by converting kinetic energy embedded in the water in motion such as ocean waves, or river flow, or wind pressure into rotational energy which is to be used to rotate the electricity generator spin axis to generate electricity. To achieve this goal, Moving Window Frame with multiple Vertical Windows and with or without a Horizontal Window is invented.

Systems and methods related to linear turbine systems are presented. Each embodiment described herein may be designed as a single-stage, linear, impulse turbine system. In an embodiment, a linear turbine includes a first shaft extending along a first axis; a second shaft extending along a second axis, the second axis being separated from and substantially parallel to the first axis; a first plurality of buckets to travel a first continuous path around the first shaft and the second shaft along a first plane, the first path including a first substantially linear path segment between the first axis and the second axis; and a nozzle configured to direct a first fluid jet to contact the first plurality of buckets in the first linear path segment.

A method for driving a transmission mechanism output power in response to an anticipated fluid-pressure gradient field is provided. The method includes sensing the change of direction of pressure gradient field at a desired location from the different area of the transmission mechanism within fluid. The method further includes constructing fluid-pressure gradient field based upon isolation-fluid apparatus or low-density fluid space installed on a transmission mechanism within fluid.

A subterranean energy storage system configured to store and subsequently release potential energy. Storage of potential energy is achieved by the transfer of a pseudo fluid from a first storage tank to a second storage tank located above the first storage tank, and is subsequently released by the transfer of the pseudo fluid from the second storage tank to the first storage tank. To transfer the pseudo fluid between the first and second storage tanks, the subterranean energy storage system comprises at least one continuous conveyor mechanism extending through at least one transport shaft, wherein the at least one continuous conveyor mechanism comprises a plurality of vessels arranged along a length of the continuous conveyor mechanism. The subterranean energy storage system further comprises an energy transfer means operably connected to the at least one continuous conveyor mechanism to transfer power to and from the subterranean energy storage system.
