A system and method for supplying electricity for use with a host device. The system includes a structure and an interface. The structure includes an array of single-walled carbon nanotubes arranged with respect to a matrix. In operation, the system receives a force stimulus for facilitating piezoelectric generation of electricity. In particular, the array receives the force and piezoelectrically generates electricity therefrom. The array is electrically coupled with the interface. The interface allows the structure to supply electricity to electrical devices that are coupled to the interface.

An electronic device with a power generator has a rotational component, a power generator, a commutator, a battery charger, and a transmission component. The commutator is electrically coupled with the power generator. The battery charger is electrically coupled with the commutator for providing a charging power source. The transmission component is coupled between the rotational component and a shaft. When the rotational component rotates, the rotational component drives the transmission component so as to make the shaft rotate and make a coil generate an induced current. The induced current is transmitted into the commutator. An output of the commutator is used to charge the battery charger.

A spacecraft power system utilizing a novel method for recharging batteries utilizing the ambient space plasma and at least two separate surface materials having different material properties is disclosed. This power system provides increased power and reduces electrical potential build-up of the spacecraft, thereby reducing the power needed from solar array panels and protecting sensitive electrical components and telemetry signals from damage or disturbance.

A cassette form factor device containing a drive wheel and a generator. The drive wheel is positioned to be in frictional contact with a pinch-roller of a cassette-playing device when the cassette form factor device is inserted into a play position on the cassette-playing device. The generator is driven by the drive wheel and generates electrical power to energize one or both of the cassette form-factor device and an external device when the cassette-playing device drives the drive wheel. The cassette form factor device may contain an MP3 player having a read/write head. The read/write head is positioned so that when the cassette form factor device is inserted into the play position on the cassette-playing device, the read/write head may provide content from the MP3 player to the cassette-playing device. The cassette form factor device may contain a rechargeable battery operatively that is connected to the generator so that the generator may recharge the rechargeable battery. The cassette form factor device may be an audiocassette form factor device.

A self-generating hand-held flashlight including the optional use of battery power. The flashlight includes a tubular body case that may be divided into three compartments. In a first compartment a generator utilizing a permanent magnet armature is mounted. This generator is electrically tied to a bulb at one end of the flashlight. The generator is powered by rotation of a central shaft coupled to a flywheel, the flywheel being located within a second and larger compartment of the flashlight body case. The flywheel is rotated by manual energy coupled to the flywheel through a power wheel and slip-clutch, both of which are also located within the second and larger compartment. Various manual means are used to rotate the power wheel. The flywheel is adapted to have a maximum inertia, thereby allowing it to rotate for a substantial period of time once initialized. A very favorable time ratio of light time to energy input time is achieved by using a high inertia flywheel that is properly balanced and mounted within the flashlight. Hence, a continuous source of light may be provided through the application of only short bursts of manual input energy. A third compartment of the flashlight housing may optionally include a battery that could be used as an alternative power source.

An improvement in a wind electric power plant of the type disclosed in U.S. Pat. No. 4,059,771. The improvement comprises including an exciter armature and an associated exciter field winding into the electric circuit disclosed in U.S. Pat. No. 4,059,771. The improved wind electric power plant is utilized to supply A.C. power to hot water heater loads and/or auxiliary loads such as air conditioners, devices to manufacture hydrogen gas and the like, wherein at least one of said auxiliary loads is solar-powered. Associated circuitry is provided so that power can be supplied alternatively to either the hot water heater loads or to the auxiliary loads. The power supplied via the associated circuitry supplements power to the at least one solar-powered auxiliary load, thereby maintaining a full load on the electric power plant to insure the quiet operation of that plant.
