A power generation system for the production of electric power or the accomplishment of other work objectives utilizes kinetic energy derived from the action of the force of gravity on a vehicle that is allowed to move along a power generation path having a downward grade. A tether cable connects the vehicle to a tether member that moves along a downhill line in response to the movement of the vehicle along the path, and the movement of the tether member operates a gearing mechanism that operates a machine to accomplish the work objective.

Method and apparatus for an improved recreational canopy which may be used with watercraft wherein the canopy is constructed by using a pair of flexible, resilient rod-like members wherein one end of each of the flexible rods is inserted through mating apertures in an upright support member mounted onto the watercraft, or other structure, so that the rods are bowed outwardly and frictionally held in the stanchion. A canopy, which may incorporate solar cell fabric, is attached between the rods so that the canopy generally appears to be in an elongated V-shaped structure which stretches across a portion of the supporting structure, such as a watercraft, between the flexible rods. The upper end of the upright support member may be pivotable and the rod-like members may be disposed in a cap removably disposed on the upper end of the upright support member. A lighting system including an alternative power source being provided on the canopy. Also, a user driven pedal system for providing propulsion to a kayak watercraft is shown which includes a generator driven by the pedal system for providing additional electrical energy for use on the watercraft and for propelling a kayak by either a propeller or flappers.

A pinion gear, with a varied gear ratio, can be inline with a rack. When the rack moves, the pinion gear can rotate. This rotation can cause an interior of an electrical generator to rotate. Rotation of the interior of the electrical generator can cause an electricity to be produced and outputted.

Provided is a wheel bearing apparatus with a generator that can have a simplified structure to reduce costs and is capable of preventing electrolytic corrosion. The wheel bearing apparatus with a generator includes a wheel bearing and a generator. The generator includes a stator attached to a fixed wheel and a motor rotor attached to a rotating wheel and is of an outer-rotor type in which the stator is located on an outer periphery of the wheel bearing, and the motor rotor is located radially outside of the stator. The wheel bearing apparatus with the generator further includes at least one conducting unit that conducts a current between the fixed wheel and the rotating wheel.

A non-polluting, zero hazardous gas emission electricity generating hybrid system is provided with a hydraulic pressure drive cylinder. To one end of the linear movement drive cylinder is connected with a fluid reservoir containing the fluid to be supplied to the drive cylinder. The fluid from the reservoir is pressured through the inlet pipes by the mechanical pump electrically connected to the motor positioned on top of the said fluid reservoir. To the other end of the linear movement drive cylinder is provided an outlet means for collecting the said fluid into the fluid reservoir enabling the linear movement for the hydraulic cylinder.

A co-constructed power generation device comprises a shell member, a first power generation group and a second power generation group, wherein the first power generation group is disposed in the shell member and generates shake-induced power, and the second power generation group is disposed in the shell member and generates rotation-induced power.

A micro power generator is provided, including a cam structure, an electromagnetic unit, a first clutch, and a first energy converting unit. The electromagnetic unit is partially disposed in the cam structure, which includes a central shaft and a first shaft gear. The first shaft gear is rotated with the central shaft. The first clutch is telescoped on the central shaft, and rotated with the first shaft gear. The first energy converting unit is connected to the first shaft gear of the electromagnetic unit. In an energy-storing state, the first clutch is connected to the cam structure and is moved with the cam structure and the first shaft gear to move the first energy converting unit and to store the kinetic energy of the cam structure to the first energy converting unit. In a power-generating state, the first clutch is separated from the cam structure.

Disclosed are a portable private power generation apparatus, and a module equipped with same, the portable private power generation apparatus being small in size, and capable of efficiently generating private power to charge a battery, and able to be linked and used with a variety of smart modules when customary power cannot be supplied in times of emergencies such as during military operations, in refugee camps, during disasters due to earthquakes and the like, emergency situations on ships, and outdoor activities. The present invention comprises: a rotatable fly-wheel member; first and second rotating members for rotating the fly-wheel member; first and second wires for rotating the first and second rotating members, respectively, by means of a pulling action; first and second spring members for carrying out winding actions of the respective first and second wires; and a power generation member for generating power from the rotation of the fly-wheel member. As such, a user can generate power continuously for an extended amount of time by repeating the action of pulling the wires with one or both hands.
