A mass displacement electricity generator, having a tower and a first mass suspended by the tower for falling and lifting. The first mass is suspended by a pulley arrangement including a first set of pulleys fixed to the tower above the first mass and a second set of pulleys fixed to the first mass. A cable extends through the first and second sets of pulleys and one end of the cable is fixed to one of the tower or to the first mass. A winch includes a barrel about which the cable winds off as the first mass falls and winds on as the first mass lifts. The winch is in driving connection with a flywheel so that as the first mass falls, the cable winds off the barrel and barrel rotation drives the flywheel to rotate. The flywheel is in driving connection with a generator so that rotation of the flywheel drives the generator for generating electrical energy.

A device and a method for converting wave motion energy into electric power are described. The device includes at least one support structure and a support frame to connect the floating element to the support structure. A linear element of motive power mounted on the support frame is movable with respect to the floating element and transfers motion to a motion conversion and transmission unit that converts linear motion into rotary motion, which drives kinetic energy accumulation elements and one or more electric power generators. The motion conversion and transmission unit, the kinetic energy accumulation elements and the electric power generators are all incorporated in the floating element.

A power generating wall design, which may include a plurality of turbines, such as wind turbines, arranged in a wall pattern and arranged to have an entrance flow on one side of the wall and an exit flow on another side of the wall. One exemplary embodiment of a power generating wall may incorporate wind turbines, and may be used in a high-wind environment, such as a highway. In another exemplary embodiment, a power generating wall may incorporate other types of turbines, such as water-driven turbines, and may be constructed in a location that is wholly or partially underwater, such as a river or tidal basin.

A dynamic vibration absorber includes a frame configured for mounting to a moveable structure; a flywheel mounted on a first shaft; and a first converter adapted to convert a linear displacement of the frame into rotation of the first shaft; including a rotary damper mounted on a second shaft; and a second converter adapted to convert a rotational velocity of the first shaft into a rotational velocity of the second shaft.

The wind generator includes a support part, a housing connected to an upper portion of the support part, the housing having an inner space, a blade part connected to one side of the housing, the blade part, an electricity generating part seated in the inner space of the housing, a flywheel, and a tail part. The flywheel includes a shaft rotating together with the blade part, a rotor coupled to the shaft, the rotor including at least one permanent magnet along an outer circumferential surface thereof, at least one coil part disposed outside in a radial direction of the rotor and around which a trigger coil is wound, the at least one coil generating magnetic fields when current is supplied to the trigger coil, and a circuit part supplying pulse-type current to trigger coil when the permanent magnet passes through a center of the trigger coil.

A flywheel includes a shaft a rotor attached to the shaft. The rotor rotates using the shaft as a central axis. The rotor includes at least one magnet along an outer circumferential surface thereof, at least one coil spaced apart from the rotor in a radial direction. The coil may form a magnetic field that exerts a magnetic force on the magnets when current is supplied to the coil by an electric circuit, thus mitigating fluctuations in rotation of the rotor.
