A mainframe mounts the drivetrain of a wind turbine, and to an arrangement comprising such a mainframe, and to a wind turbine having a corresponding arrangement. For the purpose of mounting the drivetrain of a wind turbine, the mainframe is realized with two bearing points that are spaced apart from each other, a partial flange, having a fastening region shaped as a circular ring segment, being provided at at least one bearing point. The arrangement comprises, besides the mainframe, at least one ring element configured to radially encompass the drivetrain. At least one ring element is fastened to the fastening region, shaped as a circular ring segment, of a bearing point of the mainframe. In the case of the wind turbine, the drivetrain is mounted by means of the described arrangement.

A method of generating power. An airborne power generating craft is connected to a floating structure using an aloft portion of a tether line. The floating structure is connected to an anchor using an underwater portion of the tether line. The anchor is secured to an underwater floor. Power is generated based on movement of the airborne power generating craft in response to a wind force. The floating structure is connected to an electrical transmission system through at least part of the tether line. The generated power is transmitted to the electrical transmission system.

A method of maintaining an offshore power plant. A plurality of airborne power generating craft are landed on or near a floating vessel. Each of the plurality of airborne power generating craft forms part of the offshore power plant.

A multi-axial wave energy conversion device includes a carrier, a main body coupled to the carrier, a wave energy conversion assembly, a rotating mechanism, a lifting mechanism and a control unit electrically connected to the rotating mechanism and the lifting mechanism. The wave energy conversion assembly is coupled to the main body and includes an arm. The rotating mechanism is coupled between the carrier and the main body. The lifting mechanism is coupled between the arm and the main body. The control unit is for controlling the rotating mechanism to drive the main body to rotate relative to the carrier around a vertical axis for adjusting an orientation of the arm relative to the carrier, and further for controlling the lifting mechanism to drive the arm to rotate relative to the main body around a horizontal axis for adjusting an included angle between the arm and the main body.

The frame-supported pump is assembled without the use of tools. In place of bolts or threaded connections, an external frame provides the support necessary to resist the internal pressure of the pump. Upper and lower pump housings include grooves that slide into a slotted support or frame—a slip-in mount. In alternative embodiments the grooves are replaced with holes that slide over rods, or other means of external support prevent the pump housings from moving away from each other during pumping. A pin is optionally used to prevent the housings from sliding out of the frame, or friction is sufficient. When the pumps are in service, the internal pressure attempts to push the housings away from each other, but this force is passed to the frame, which responds with a matching force, keeping the housings in place.

An apparatus for generating electricity from falling material includes a capture wheel arranged to receive a falling material and be rotated thereby. The capture wheel may be mounted on a transportable housing having a generator therein. The housing may be a shipping container and the apparatus may be arranged to fit entirely within the shipping container for transportation. The capture wheel may include a hub comprising a central core encapsulated in a layer of resilient material; a wheel framework extending from the hub, wherein the wheel framework is connected to the resilient layer; and a plurality of bucket sections mounted on the wheel framework and arranged to receive the falling material. The hub may be a tri-layer hub including a central core, a layer of resilient material, and an outer support ring surrounding the layer of resilient material. A method of generating electricity using such an apparatus is also disclosed.
