A self-generating power supply apparatus includes a power generating body, an energy harvester, and a power consumer. The power generating body generates an electromagnetic field when a force is applied, an energy of the electromagnetic field is received by the energy harvester and subsequently transferred to the power consumer; or alternatively, the energy harvester is not provided and the energy of the electromagnetic field is directly received and used by the power consumer. The energy of the electromagnetic field is harvested by the energy harvester contacting or not contacting the power generating body, and then is converted into electrical energy, which is transferred out in a wired or wireless manner to enable self-generating power supply for the apparatus. The self-generating power supply apparatus has an immeasurable impact on the development in the fields such as wearable devices, small mobile communication devices, Internet of Things, new energy etc.

An assembly for generating electricity includes a circular track configured to rotate about a first axis of rotation, the circular track comprising a first magnet having a face that is at an angle with respect to the first axis of rotation, a second magnet positioned at a center of the circular track, wherein a face of the second magnet is an opposite polarity to the face of the first magnet such that the second magnet repels the first magnet to rotate the circular track, and a device for converting rotational motion from the circular track into electricity.

Various aspects include electric generators configured to boost electrical output by leveraging electron avalanche generated by a high energy photon radiation source. In various aspects, an electric generator includes a stator and a rotor positioned within the stator, wherein the stator and rotor are configured to generate electric current when the rotor is rotated, and a high energy photon source (e.g., a gamma ray source) positioned and configured to irradiate at least a portion of conductors in the rotor or stator. In some aspects, the stator generates a magnetic field when the electric generator is operating, and the rotor includes armature windings configured to generate electric current when the rotor is rotated. In some aspects, the high energy photon source includes cobalt-60 and/or cesium-137.

Wireless power transmission (WPT) systems are provided. For example, the WPT system can use one or more power transmitting coils and a receiver for electromagnetically coupled wireless power transfer. The electrodynamic receiver can be in the form of an electrodynamic transducer where a magnet is allowed to oscillate near a receiving coil to induce a voltage in the receiving coil, a piezoelectric transducer where the magnet causes a vibrating structure with a piezoelectric layer to move, an electrostatic transducer where movement of the magnet causes a capacitor plate to move, or a combination thereof. An alternating magnetic field from the transmitting coil(s) excites the magnet in the receiver into mechanical resonance. The vibrating magnet then functions similar to an energy harvester to induce voltage/current on an internal coil, piezoelectric material, or variable capacitor. Embodiments utilize magnetic coupling and electromechanical resonance for safe, spatially distributed, low-frequency power delivery to portable devices.

A non-rotating alternating current (AC) generating device for generating an AC current, includes: two or more generator units which are placed next to each other, wherein the generator unit includes a round bar-shaped core member, a field magnet in which an electric line is wound and a first hollow portion is formed in the central portion, the field magnet disposed on the outside of the core member through the first hollow, an armature in which an electric line is wound and a second hollow portion is formed in the central portion, the armature disposed on the outside of the core member through the second hollow portion, a pole piece which is provided between the field magnet and the armature, and insulating plates which are disposed between the field magnet and the pole piece and between the armature and the pole piece.

The devices and methods described herein are utilized to continuously track unpowered logistics platforms such as semi-trailers and intermodal shipping containers. In some examples, a tracking device harvests the kinetic energy of oscillatory movements of the shipping container to power the tracking device. In some instances, the shipping container is moving on a roadway, railway, or waterway. In other examples, a tracking device harvests the kinetic energy of airflow moving around the shipping container. In some instances, the airflow is caused by movement of the shipping container. In other instances, the airflow may be caused by ambient weather such that air is flowing around a stationary shipping container.

A method and system for cost-effectively converting a feedstock using thermal plasma, or other styles of gassifiers, into an energy transfer system using a blended syngas. The feedstock is any organic material or fossil fuel to generate a syngas. The syngas is blended with any fuel of a higher thermal content (BTU) level, such as natural gas. The blended syngas high thermal content fuel can be used in any energy transfer device such as a boiler for simple cycle Rankine systems, an internal combustion engine generator, or a combined cycle turbine generator system. The quality of the high thermal content fuel is monitored using a thermal content monitoring feedback system and a quenching arrangement.
