A mobile offshore electric power system used for generating electricity from an ocean current or a navigable river current. The offshore electric power system uses a platform from a decommissioned oil drilling rig to suspend one, two or more hydro-kinetic turbines, with electric generators, in the ocean current. The electric generators are connected to an electric generator cable to the platform and then transferred to an onshore electric cable connected to a power grid. The platform can be from a converted semi-submersible drilling rig, which is anchored to an ocean floor. Also, the platform can be from a jack-up drilling rig. Further, the platform can be mounted on a large ocean-going boat, with a dynamic positioning system, used in a navigable river.

Multiple horizontal axis type rotors are coaxially attached along the upper section of an elongate torque transmitting tower/driveshaft, The tower/driveshaft projects upward from a cantilevered bearing means, and is bent downwind, until the rotors become sufficiently aligned with the wind to rotate the entire tower/driveshaft, Power is drawn from the shaft at the base. Surface mount, subsurface mount, and marine installations, including a sailboat, are disclosed. Blade-to-blade lashing, and vertical axis rotor blades may also be included. Vertical and horizontal axis type rotor blades may be interconnected along the length of the tower/driveshaft to form a structural lattice, and the central shaft may even be eliminated. Aerodynamic lifting bodies or tails, buoyant lifting bodies, buoyant rotor blades, and methods of influencing the tilt of the rotors, can help elevate the structure. This wind turbine can have as few as one single moving part.

A charging assembly includes a conduit assembly configured to be fluidly coupled with a pre-existing conduit through which a liquid flows, and a hydroelectric generator coupled with the conduit assembly such that at least part of the liquid flowing through the pre-existing conduit flows through the hydroelectric generator. The hydroelectric generator is configured to create an electric current based on flow of the liquid through the hydroelectric generator. The assembly also includes an energy storage assembly conductively coupled with the hydroelectric generator. The energy storage assembly is configured to store electric energy of the electric current created by the hydroelectric generator.

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).

A mobile communications device includes a wireless communication transceiver to communicate commands or messages and to receive commands, measurements or messages, one or more memory devices, one or more processors, computer-readable instructions stored in the one or more memory devices, accessed from the one or more memory devices and executable by the one or more processors to cause the mobile device to communicate, via the wireless communication transceiver, commands, messages or instructions to a first umbrella to control some operations of the first umbrella and communicate, via the wireless communication transceiver, commands, messages or instructions to a second umbrella to control some operations of the second umbrella. The wireless transceiver may communicate utilizing a personal area network (PAN) communications protocol, a wireless local area network communications protocol or a cellular communications protocol.

A wind turbine (1) comprising a tower structure comprising a main tower part (2) extending along a substantially vertical direction and at least two arms(3) is disclosed. Each arm (3) extends away from the main tower part (2) along a direction having a horizontal component, and the arms (3) are arranged to perform yawing movements. Two or more energy generating units (4) are mounted on the tower structure in such a manner that each arm (3) of the tower structure carries at least one energy generating unit(4), each energy generating unit (4) comprising a rotor (5) with a hub carrying a set of wind turbine blades(6). The main tower part (2) is provided with a cable supporting structure (7) allowing power cables (8) of a power grid to be mounted on the main tower part (2).

The application relates to unidirectional hydrokinetic turbines having an improved flow acceleration system that uses asymmetrical hydrofoil shapes on some or all of the key components of the turbine. These components that may be hydrofoil shaped include, e.g., the rotor blades (34), the center hub (36), the rotor blade shroud (38), the accelerator shroud (20), annular diffuser(s) (40), the wildlife and debris excluder (10, 18) and the tail rudder (60). The fabrication method designs various components to cooperate in optimizing the extraction of energy, while other components reduce or eliminate turbulence that could negatively affect other component(s).

The invention relates to a wind driven power plant comprising a nacelle having a nacelle cover and a helicopter hoisting platform, the nacelle further comprising a hatch extension and a hatch cover, the hatch extension being arranged between the nacelle cover and the hatch cover, wherein the hatch extension has a channel-like shape, wherein the hatch cover is mounted on top of the hatch extension, and wherein a the hatch extension provides a distance between the hatch cover and the nacelle cover.

A plenum resident wind turbine sustainable energy generating system is disclosed. An example embodiment includes: a wind turbine assembly installed in a plenum of a heating, ventilating, and air conditioning (HVAC) unit, the wind turbine assembly including a plurality of blades and a transverse shaft; and a generator coupled to the shaft of the wind turbine assembly.
