A superconductor-based engine including a temperature-controlled superconductor that acts as a source for mechanical motion transmission. In one aspect, an oscillating motion is obtained in accordance with switching alternately between a superconductivity state and a non-superconductivity state of the temperature-controlled superconductor.
