The mathematics for the magnetic research has shown it's most likely very difficult to overcome the losses.

Hi Craigy,
It's not possible to know how much energy is exchanged during Magnetocaloric effect from just a change in temperature. One would also need to know the change in specific heat capacity due to the change in magnetic field, which would make a significant difference at ambient temperature (so-called thermal equilibrium). Lets consider an example of magnetic material below Curie temperature at ambient temperature. When the magnetic field is applied, potential energy is released, but most (not all) of such energy goes into various areas such as the lattices, magnetocrystalline anisotropy, etc. Even though there's a significant release of potential energy with the increase in applied magnetic field, most of it's not translated into a change in temperature. If Steorn said the equated energy from Magnetocaloric effect is insufficient, and they made no reference to taking sensitive specific heat capacity measurements, then such information is unfortunately meaningless.

I'm not sure what type of device you're describing there. If the device captures energy from ambient thermal energy per cycle, then it would definitely violate the 2nd laws of thermodynamics.


We must be talking about two different devices. In reference to my Free Energy devices (1 through 3), they would produce continuous power 24 hours per day, 365 days per year at any hospitable location on Earth while *not* requiring any macro scale temperature gradients. That is called a perpetual motion machine of the 2nd kind, and clearly violates the 2nd laws of thermodynamics.  May I ask what device you were referring to?

Sorry Paul , i didn´t want to take this thread off topic, and you are right in that i was speculating to my Dr. of physics about the steorn orbo and whether magneto calorific effects were playing a part in its operation, i guess the jury is out on that score..the main focas of the debate was on what happens in a magnet to magnet transaction with helpings sv. When i look at your designs , i see a lot of similar questions although you are using an oncoming field from a coil rather than an approaching magnet...I am thinking of investigating a little further when time permits.
 > Now if we have removed the field quickly enough that we have escaped quicker than the sv lag time.( time in seconds required by material to return to retentivity ) the domains are in the stressed state that they were in before , but now there is no field to help them return to retentivity, so the magnets will reverse the magneto calorific effect, i.e. it will suck in thermal energy from the surroundings to enable the material to return to retentivity.

> . Here is a good analogy. When you orientate all those domains in one direction, you have put some structure into the material. Thermodynamics lets you quantify the heat consequences of this using the concept of entropy. More entropy corresponds to more disorder, less entropy to more structure. A relevant analogy is an ice cube in a glass of water.  The ice cube is chemically the exact same stuff as the water, but it is structured. (just like the domains in the ferromagnet) The water molecules will do their normal thing threshing around due to the effects of heat, and as they collide with the structure of the ice cube, they knock bits off it until the whole thing is reduced back to water again. When all is said and done, the glass contains only water. But without some outside influence, the temperature of the water is colder than it was before the water worked on the ice cube. By destroying the structure, the water has become colder – heat has been taken out of it.

> Going back to the analogy of the ferromagnet, the heat energy in the solid vibrates all the molecules around and gradually disorganizes them. So quite spontaneously, the material relaxes back to its starting state, but when this is all over the material is a little colder. If you want to do this again, you have to supply some heat. In an experiment with an Orbo, currents of air in the room could easily provide enough heat to reset the material so that after a short while it could repeat the Sv transaction all over again. You made the good observation above that the initial approach of the magnet will generate some heat. This will be balanced by the loss of heat when the material relaxes after the departure of the magnet.

 The trouble with Steorn's experiments is, that only a tiny amount of heat can make a huge amount of mechanical energy. (I remember that you have one of those little demonstration Carnot cycle engines, which start running when you put your finger on them.) So in order to keep track of the accounting between heat and mechanical energy, you have to be quite fanatical in watching out for the tiniest temperature difference.

Thanks for wealth of info Gary. That's an elaborate design. The only thing is it needs to work for steel wire, so it's more difficult to bend. For steel, it may be easier just to dip the wire by hand, unless one is going to be making a lot of "free energy" devices.

Thanks for telling me about shellac. A little reading at wikipedia shows this is a good choice. I wondering if hairspray has any shellac or something compound. Do you know how fast shellac dries?

This is too funny. I hope legit people are taking note to all of the potshots.

Anyhow, the answer is simple. The mathematics for the magnetic research has shown it's most likely very difficult to overcome the losses. Diode research is a guarantee! The diode arrays are considered infinite efficiency since no voltage source is required.

All that's left is to come up with an inexpensive easy method of making semiconductor fabrication equipment that anyone could build to make their own diode array *chips* that could power their home and beyond. They could be the hero of the block by selling inexpensive chips to the neighbor.
