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.

An extended duration burst electrical energy harvesting generator in one embodiment including two magnets situated on opposite ends of an angular movable lever with a centered fulcrum support in an angular displacement (see-saw) arrangement. The two magnets are under the bi-stable magnetic attractive influence of dual magnetic metal (high permeability) substrates that are disposed at a distance within two separate center core electric coil bobbin forms that are situated under the opposite ends of the lever. Either one of the magnets, in time, will make or break contact with one of the substrates producing an instantaneous induced voltage at each of the coil terminals. The two induced voltages can be utilized to power battery-less and wireless remote communications control function such as ISM Band wireless transmitters and battery-less electronic device applications.

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.

A system and method for harvesting electric energy from the earth's gravitational field includes a pneumatic, potential energy (PE) system which cumulatively generates a volume of compressed air with an energy equal to PE, during a predetermined duty cycle. This energy can then be released as an instantaneous burst of energy in the next consecutive duty cycle. Also included is an electro-magnetic system which continuously generates kinetic energy (KE) as a shuttle falls under the influence of gravity during each duty cycle. An interface between the two systems is provided by a water column that separates the two systems yet allows them to be interactive. Specifically, the burst of PE manipulates the water column to maintain its integrity as the shuttle uses the water column as a water pathway for a return to the shuttle's start point under the influence of its buoyancy.

Provided is an electric motor combined with a power generator comprising: a fixed coil plate in which separate coil bodies are uniformly arranged; and a reciprocating magnet plate in which separate magnets are uniformly arranged. The installation location of the electric motor combined with a power generator is not restricted by linearly or rotationally moving equipment. In addition, the electric motor combined with a power generator enables coils and magnets to be regularly and closely arranged in the coil plate and the magnet plate, thereby minimizing loss of the locomotive force. Furthermore, when performing a reciprocating movement to which an inertial force is added, the electric motor combined with a power generator enables electric current to be instantly broken and converted and supplied by sensing of sensors, while implementing a strong reciprocating movement due to an increase of speed by means of the compression and repulsive force of a spring.
