A system and method (1000; 1050) for a well structure adaption (402) to be used with a wellhead casing for a reusable system (942; 962A; 962B), such as a system for renewable energy generation is disclosed. A well structure adaption includes an annular feature (404; 506) and a housing (412; 504). The annular feature includes a narrowing (406) therein and is able to fit over the wellhead casing (110; 202). The housing is associated with a segmented clamp (508) and a drive screw (502). The housing is to fit over a portion of the annular feature. The drive screw is to enable the housing to be releasably clamped to the annular feature with the segmented clamp. The housing can support at least one aspect of a reusable system thereon.

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.

The present invention is a wind generator system particularly suitable for small wind applications that harnesses low velocity wind effectively. The wind generator system comprises a drive shaft; one or more retreating blades and one or more advancing blades attached to the drive shaft and extending radially outwardly therefrom; a generator assembly coupled to the drive shaft and effective for generating electrical power; and a energy storage system comprising a mechanical bellows.

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).

Disclosed are systems and method that generally relate to the capture of wind energy by small wind turbines mounted on buildings with gabled roofs. Wind energy harnessing system for gabled roof buildings having a roof ridge including a low silhouette visually appealing enclosure mounted along the roof ridge of a building and extending down both sides of the roof forming the ridge. The enclosure includes airflow guides defined by columns extending down a length of both sides of the building roof forming sidewalk and a roof formed of pivoting louvers above the columns. A paddle-wheel type wind turbine consists of a multiple-bladed cylindrical shaft that contacts the wind and provides rotational work mounted within the enclosure and a generator connected to the wind turbine for converting the rotational work from the wind turbine to electrical energy. The enclosure for the wind turbine functions to capture wind and directs the airflow via the airflow guides before it reaches the ridge.
