An asymmetric flywheel is coupled to an input gear that is attached to a lever or alike. The input gear and flywheel gear are engaged as the user rotates the lever. As a result, the flywheel spins and electricity is generated by the micro electromagnetic generator. When there is no direct user manual input, the input gear and the flywheel gear are disengaged. The flywheel is an unbalanced pivoted mass that rotates with inertial forces from physical accelerations by user's movement and gravitatio...

A cord reel box with recharging unit has a housing, a rotating plate, a volute spring, a communication cord, a recharging unit, and a pressing device. The gear mechanism is assembled between the rotating plate and the regenerator. The pressing device is pivotally mounted on one side of the housing. The gear mechanism is assembled between the pressing device and the regenerator. An AC plug is mounted on the housing and electrically connecting with the PCB. The PCB has a transformer mounted thereo...

The invention concerns a handheld power generator for generating electrical power for a consumer device, the generator comprising a main casing housing an input gear for driving an alternator via at least one intermediate gear so as to provide a step-up drive ratio in the range of 10:50; the input gear, the or each intermediate gear, and the rotor of the alternator all having their rotational axes perpendicular to the base of the main casing so that the gears and rotor rotate parallel to the pla...

This invention relates to a new and useful improvement of an earlier scheme patented by this inventor (Canadian Patent No. 1,245,992, issued Dec. 6, 1988) for generating electricity using gravitational energy. The improved scheme uses a set of massive underground spinning wheels, wherein each wheel is geared to a large driving wheel requiring a lower input torque, which wheel is then fitted with a mechanism to receive and transmit gravitational torque pulses from a passing vehicle to keep the wh...

In an engine generator unit, an engine is connected with an outer-rotor/magnet type generator that has a cantilevered outer rotor functioning also as a substitute for an engine fly wheel. Cooling fan device is attached to the outer rotor. The generator and cooling fan device are covered with a fain cover that is made of die-cast aluminum alloy. The fan cover has, at its one end remote from the engine, a cooling-air inlet portion for introducing cooling air from the outside via the cooling fan de...

The dynamo for/on bicycles comprises a housing (1) which can be secured to the bicycle and accommodates a stator (2) and a rotor (3); the rotor (3) can be set in rotary motion by a drive member (4), which can be driven by a bicycle wheel. The drive member (4) is mounted rotatably around a wheel axle (6) so as to be kinematically connectable with the wheel and forms part of an engageable and disengageable dynamo gearing (7) which rotates the rotor (3) in dependence on the rotation of the wheel.
