Entropy Engine

[abv]

You maybe right smokey.  If you can have an area inside a magnetic field with a higher temp than an area outside of a magntic filed why wouldn't you just use a peltier electric generator to use the temp difference between the two locations to generate power. Or if you must ye old sterling engine.

The changes of heat capacity is not generate a heat. It changes temperature while magnetic spins of electrons arranged by an external magnetic field into one direction. If this heat will be taken by external object at this heating time, then at time when the substance will be outside this external magnetic field then the substance will cool down to more low temperature than it was before heat. This idea used in system of magnetic refrigeration. The heat should not be goes out from system. Or external temperature should be in range of working engine condition. Therefore the heat and cool losses would be similar. However, this will reduce the magnetocaloric effect.
The main idea of this model is showing how to use difference of magnetic field intensity to induce heat difference in certain time to make a mechanical oscillation.

The previous poster is correct, this type of system (entropy engine) does not create "heat".
it creates "cold", or a reduction of heat.

we can use cold, in the same manner in which we use heat.
our heat engines operate on a difference of temperature, regardless of which direction the heat is flowing.

The reason I suggested a Sterling Engine, vs. a Peltier/Seedbeck generator
Is because of the necessity of switching.
In order to use a peltier-type device, you must switch polarities once equilibrium is reached.

The gas-cycle enables use to change directions with reaction to the expansion/compression process.
This is directly controlled by a change in temperature.

remember, in this scenario:
Temperature only changes during the time the magnetic flux is changing.

once the field stabilizes, there is no further change in temperature.

What we are using for a "gain" in energy, or "OU" potential is:
the difference between the original temperature, and the temperature after cooling (when removed from the field at the end of the cycle).
The heat energy gained during the induction process is exactly equal to the energy required to pull the magnetized mass out of the respective field.
The heat energy LOST during de-magnetization: represents a "gain" in entropic energy.

loss of energy is the same as a gain, if you look at the circuit in reverse

we are utilizing the compression function of the cooling process to gain free energy.

NOW - that being said, I believe the magnitude of this "free energy" to be insignificant.
However, it does demonstrate a violation of thermodynamic theory.
which is equally as important as the perpetual (circa 1980's) Coleman Cooler.

Smokey, have you any links to this device? I couldn't find much after 10 mins of searching. Cheers Pomo.

This is how I had envisioned a peltier would work but is probably an exercise in futility (but hey why else are we here)

The sad fact that a heat pump with a proven COP of 3 (compressor/vapor/liquid) system can't be made into an over unity device seems to indicate that this system probably also won't work. Imagine a system where 1kw heats a room with 3kw. This is not fantasy but real. But alas,those free 2kw cant be used to loop the system. How sad is that?
