Thanks for the kind words, and let me urge you to continue your experimentation.
Also, please check Dilip Kondepudi and Ilya Prigogine, Modern Thermodynamics: From Heat Engines to Dissipative Structures, Wiley, New York, 1998, reprinted with corrections 1999. Areas already known and recognized to violate thermodynamics are given on p. 459; one such area is sharp gradients.
So in applying sharp gradients, one is using a well-established (but not understood) are the thermodynamicists themselves tell us can and often does violate thermodynamics (specifically, the infamous second law).
So your research ideas are well-founded and centered about an area that the leading scientists in forefront thermodynamics agree can do some "very strange" things, and disobey the second law.
We have corresponded a few times in the past and spoken on the telephone a few times as well and in one of those phone conversations I asked you about the transient behavior of a parallel or shunt wound DC motor when you disconnect the field winding. In my college EE machines lab, the instructor told us this could result in a sudden torque transient that would destroy the motor. He showed us that the normal field rheostat when increased in resistance to slow the motor down actually results in a temporary increase in rpm for just a slight increase in resistance. It was not hard to imagine what disconnecting it would do with the collapse of the field magnetism. Could you put me in touch with the writer of the October email on this subject as I have some ideas about alternative compound motor hook-ups that may have unexpected results as you probably do too. We also talked about parametric amplifiers that the Russians developed long ago. If you have a 3 phase wound rotor machine you can make the armature field rotate faster or slower than the shaft speed by application through the slip rings of a 3 phase current. If you feed back the stator current to the rotor the frequency will go out of control, unless you know what you are doing which I don't at this point. I am trying to find a reasonably priced 3 phase wound rotor machine to tinker with. Your works are an ongoing inspiration. Hope your health and your wife's continue to improve. Retirement shouldn't be so draining.
