A turbine which uses fluid pressure to turn a shaft in a manner that does not allow for cavitation to be created.

Disclosed is conduit anchor, an offshore system comprising a conduit anchor and a method of deployment. The conduit anchor includes a base section adapted for attachment to a conduit, and a conduit guide extending from the base section. In use a dynamic conduit extends along a dynamic conduit pathway range defined by the anchor, via the conduit guide. The conduit guide comprises a convex bend protecting surface region oriented towards the dynamic conduit pathway range which in use protects against over bending of the dynamic conduit.

A downhole turbine may include a stator disposed in a turbine housing, a rotor disposed between the stator and the turbine housing and wherein the rotor includes an outer housing, a gap that separates the stator and the rotor, wherein the gap is oil filled, and one or more blades disposed on the outer housing between the turbine housing and the rotor. The downhole turbine may further include a compressible medium attached to the outer housing between the stator and the outer housing, wherein the compressible medium is separated from the stator by the gap, and one or more magnets attached to an inner surface of the compressible medium, wherein the one or more magnets are separated from the stator by the gap.

A system and method for generating electricity from a flowing fluid, the system comprising a smart flow concentrator including an energy harvester, and a central computer and control system for controlling the operation of the smart flow concentrator and of the energy harvester. The energy harvester includes a drive foil section including a plurality of drive foils configured to generate electricity from the fluid flow passing through the smart flow concentrator.

A system for converting fluid flow into electricity. The system has an arm assembly with four floats that rotate around a center float. The floats on the arm assembly are all provided with impellers that turn one half revolution for every one revolution of the arm assembly. This slow rotation maintains the impellers at the optimal angle to convert the flow of the water current into rotational motion of the arm assembly, regardless of the orientation of the arm assembly. The arm assembly is coupled to an electric generator provided on the center float that converts torque generated by the arm assembly into electric power that may either be stored on an on-board battery or transmitted by wire for use elsewhere.

A power generation system anchored to a hydraulic arm, capable of pivoting up or down to optimize power generation based upon the present conditions of the flowing body of water. The turbines are augmented by diffusers to improve fluid flow and power generation. The overall design is easily built, installed, and maintained, providing easy power to homes without a need to connect to a public grid, and safety measures are affixed to prevent undesired items from entering the turbine propellers.

Systems and methods for hydro-electric power generation are disclosed. The system includes a frame or structure positioned in a waterway or channel, with one or more hydro-transition units secured to corners of the frame. The hydro-transition units include a body of reinforced fabric for redirecting water flow towards the inlet of the frame, effectively increasing the current of the water and allowing for turbines within the frame to generate power at an increased rate. Anchors and bracket systems may secure the hydro-transition units to both the waterway and the frame, thereby allowing the body of reinforced fabric to withstanding force from water-flow within the waterway. The system includes various failsafe mechanisms for disengaging or detaching the hydro-transition units from the frame and/or anchor for reacting to high water flow or volumes (e.g., flooding).

According to an embodiment of the present invention, a tidal power generator may comprise: a plurality of channel levees which are arranged spaced apart from each other so as to form a channel having a constant width and which have a plurality of installation grooves, each being formed by recessing the surface facing the channel, wherein a tidal current can move forward/backward in the channel; a first water collection levee extending from the front end of the channel levees with reference to a movement direction of the tidal current and having a peak shape of which the width is gradually reduced towards the front side of the channel; a second water collection levee extending from the rear end of the channel levees with reference to the movement direction of the tidal current and having a peak shape of which the width is gradually reduced towards the rear side of the channel; and a waterwheel module which is inserted and installed in the installation groove and can generate power using movements of the tidal current.
