Abstract
Methods for increasing the power output from a heat engine based on temporary electrical and magnetic remanence is achieved by a means of cancelling the power limitation caused by re-magnetization fields and methods for varying the turns-ratio of the output coils as the flux decays.
Claims18
An apparatus for performing a thermodynamic cycle, comprising:
- a sample that exhibits temporary magnetic remanence;
- a magnetisation arrangement to magnetise the sample during a first portion of the cycle;
- a power collection arrangement to generate electrical power due to a first magnetic field generated by the sample as a result of decay of independent magnetic flux during a second portion of the cycle;
- a field cancellation arrangement to cancel at least partially a second magnetic field generated by the sample during the second portion of the cycle, wherein the second magnetic field would tend to oppose, or decrease the rate of, demagnetisation of the sample;
- wherein the field cancellation arrangement produces a cancelling field to cancel at least partially the second magnetic field, and wherein the field cancellation arrangement comprises a current detector operable to detect current induced by the second magnetic field, and wherein the field cancellation arrangement is operable to produce the cancelling field based on the detected current.

An apparatus according to 10, wherein the cancellation field is generated by passing the inverted version of the detected current through one or more cancellation coils.
An apparatus for performing a thermodynamic cycle, comprising:
- a sample that exhibits temporary electrical remanence;
- a co-material that exhibits temporary magnetic remanence, the co-material being placed in close proximity to the sample;
- a polarisation arrangement to polarise the sample during a first portion of the cycle;
- a power collection arrangement to generate electrical power due to a first magnetic field generated by the co-material as a result of decay of independent magnetic flux during a second portion of the cycle;
- a field cancellation arrangement to cancel at least partially a second magnetic field generated by the co-material during the second portion of the cycle, wherein the second magnetic field would tend to oppose, or decrease the rate of, demagnetisation of the co-material;
- wherein the field cancellation arrangement produces a cancelling field to cancel at least partially the second magnetic field, and wherein the field cancellation arrangement comprises a current detector operable to detect currents induced by the second magnetic field, and wherein the field cancellation arrangement is operable to product the cancelling field based on the detected current.
