| 摘要 |
Improved energy conversion devices comprise a first ferromagnetic element, a second ferromagnetic element oriented such that similar poles of the first ferromagnetic element and the second ferromagnetic element can be positioned proximate each other, and a mechanical element connected to the first ferromagnetic element such that movement of the first ferromagnetic element can actuate the mechanical element to provide mechanical work. In some embodiments, the energy conversion devices can further comprise an externally powered temperature control device to selectively alter the temperature of the ferromagnetic elements to change the Curie temperature of the ferromagnetic elements. The change in temperature of the ferromagnetic elements and the orientation of the first and second ferromagnetic elements allows the repulsive force between the first and second ferromagnetic elements to result in mechanical work.
