A method and apparatus for motional / vibrational energy harvesting are disclosed. Embodiments of the subject invention utilize the non-resonant chaotic behavior of a free-rolling magnet to generate power. In one embodiment, the magnet can be spherical, cylindrical, or elliptical. The magnet can roll about a linear, cylindrical, helical, or cage-like track. The changing magnetic flux due to the magnet rolling about the track induces current in surrounding coils. The coils can be provided around the track using a continuous winding placement, segmented winding placement, or fractional winding placement. Multiple coil phases are also possible. For embodiments utilizing multiple magnets, spacers can be used to maintain a separation between magnets.

Supersonic Magnetic Advanced Generation Jet Electric Turbine (S-MAGJET) described herein, and a subsonic derivative, MAGJET, integrate a gas power turbine, superconducting electric power and propulsion generation, and magnetic power flux field systems along with an ion plasma annular injection combustor which utilizes alternative petroleum-based fuel and combustion cycles to create a hybrid turbine turbomachine for aerospace propulsion. The propulsion unit is able to achieve a dramatic increase in horsepower, combustion and propulsion efficiency, and weight reduction. In addition, the turbomachinery structures may be disposed within an exo-skeleton architecture that achieves an increase in thrust to weight ratio with a concomitant increase in fuel efficiency and power generation over traditional gas turbine technology today. The engine continuously adjusts the temperature, pressure and mass airflow requirements using an electromagnetic power management system architecture. Engine performance may be controlled across the entire desired flight envelope, whether subsonic, transonic or supersonic flight conditions. With bypass fan(s), compressor stages and turbine segments controlled electrically in a shaftless turbine design, the S-MAGJET maximizes the propulsion efficiencies over a broader range of operating conditions compared to current art of turbine technology and at much higher thermodynamic and aerodynamic efficiencies.
