A fluid power generating apparatus includes a loading seat, a power generating mechanism, a transmission mechanism and a generator. The power generating mechanism includes a primary shaft, a plurality of driving wheels and a fan. The driving wheels with the fan are connected to the primary shaft and simultaneously rotate. The transmission mechanism includes a driven shaft, a plurality of driven wheels and a hollow body. The rotating direction of the driven shaft and the hollow body is different. The generator includes a primary rotor and a secondary rotor. The primary rotor is connected to the driven shaft. The secondary rotor is connected to the hollow body.

A generator-type pressure relief device includes: a housing; a propeller disposed in the housing; a shaft fixed to the center of rotation of the propeller; a generator unit that generates electricity by receiving rotational torque from the shaft; an electricity storage unit that stores electricity generated by the generator unit; an electronic brake operated by an electric signal supplied from the outside to suppress the axial rotation of the shaft; a control unit that sends an electric signal to the electronic brake to control the operation of the electronic brake; and a water pressure sensor provided in the water supply pipe or the water drainage pipe or the housing so as to transfer water pressure information on the water to the control unit, and which allows the control unit to control the electronic brake.

A device is provided that converts random movement of extrinsic oscillation 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 body which provides the randomized kinetic motion that drives an articulating arm, and may include a series of connected pivoting arms of different lengths. The transmission unit is the portion of the device that converts the random motion of the articulating arm into unidirectional rotation of a shaft that is converted into purposeful torque. The device may be placed in almost any type of environment to take advantage of any type of kinetic motion, including water, wind, mechanical movement and even human movement.

An apparatus for extracting power from water waves comprises one or more pairs of interconnected buoyant members that move relative to each other when subjected to wave kinetic energy. Each pair is connected by a universal joint allowing rotation about first and second axes. Coaxial bevel gears are configured to rotate about these axes, with each pair consisting of gears restricted to opposite rotational directions. The apparatus includes a gear system linked to the bevel gears, enhancing rotational velocity. A drive shaft, connected to the gear system, rotates to power an electric generator. This configuration ensures continuous electricity generation from the movement of interconnected buoyant members, regardless of the direction of their relative movement.
