An apparatus has at least one buoyant member pivotally connectable to an adjacent member and configured for relative movement about a first axis of rotation when acted upon by one or more incident waves. At least one pair of bevel gears are arranged to rotate about the first axis of rotation upon relative movement between the pivotally connectable members. The bevel gears mesh with a corresponding pinion gear which is attached to a rotatable drive extending substantially perpendicularly from the first axis of rotation. The pair of bevel gears are configured to engage the pinion gear in opposite directions respectively to drive the pinion and rotatable shaft to rotate in a single direction regardless of the direction of movement of the pivotally connectable members. The rotatable drive shaft is connected to a generator for the generation of electricity when the apparatus is subjected to incident water waves.

A vertical axis wind turbine includes two or more cells arranged one above the other along a vertical machine axis, in which each of the cells includes a plurality of vertical blades which are arranged within the cell distributed on a concentric circle about the machine axis and which are connected so as to be able to move together on this circle and which are rotationally fixed with a main shaft, and in which the blades in the cell are each individually mounted so as to be able to rotate about a vertical axis of rotation which in particular runs internally through them. Assigned to each of the blades are means by which the blade is made to adopt, a rotational position, about its axis of rotation, which is predetermined and can be changed at any time.

Apparatuses, systems, and methods are provided for generating power. A pipe having an input flow is coupleable to an input section configured to receive at least a portion of the input flow. A generation section is coupleable to the input section and includes a pipe section to carry the at least a portion of the input flow, a turbine coupleable to the pipe section and configured to capture energy from the at least a portion of input flow carried by the pipe section, and a generator coupleable to the turbine and configured to generate power from the energy captured by the turbine. An output section may be open ended and configured to provide a discharge for the generation section away from the pipe.

The present disclosure provides a small, inexpensive, long-lived underwater beacon locator. The beacon locator can illustratively include a housing, a communications link, a processor, a plurality of hydrophones and a motion generator.

A ram air turbine is provided that utilizes a one-piece strut. The strut includes an integral gearbox section and an integral drive section. Within the strut, a turbine shaft and a bevel gear engages a driveshaft and a pinion gear, which transfers rotation from the turbine to a generator. The strut may be machined from a single piece of metal, such as aluminum.

An air capture turbine comprises a centrifugal fan having a plurality of fan blades and a wall from which the blades extend, and a cowling having an inner wall. The centrifugal fan housed to the inside of the inner wall of the cowling. The centrifugal fan has a ring gear mounted on a lower side thereof, the turbine further comprising at least three energy converters, each including a gear wheel for engaging the ring gear. The weight of the centrifugal fan is supported by the at least three energy converters, and the inner wall of the cowling has a plurality of openings formed therein and closure members for selectively closing one or more of the plurality of openings, the openings providing or ingress and egress of air flowing in the direction of a prevailing wind to and from the centrifugal fan and the closure members protecting fan blades moving towards the direction of the prevailing wind from being engaged by air moving in that direction.

A floating power generator having a water wheel and electrical generator. The floating power generator can comprise a variable speed drive.

A device is provided that converts random movement of extrinsic oscillation from an ocean wave into purposeful movement, such as torque or other motion that can be used to generate electricity. This device may include but is not limited to two major components: 1) a collection unit and 2) a transmission unit. The collection unit represents the interactive part of the device that interfaces with an extrinsic force which provides the randomized kinetic motion that is translated by an actuating arm connected with the transmission unit into pivoting bidirectional movement along at least two directional axes, and may include a series of connected pivoting arms of different lengths. The transmission unit is the portion of the device that converts the pivoting directional movement of the actuating arm or arms into rotation of a drive shaft that is then converted into purposeful torque, and thus, electricity.
