Great for you.  Be sure to let everyone know the day that Hell freezes over and you are able to successfully close the loop and make a self-runner.

Steam punk!

Steam punk is great.  The trouble here is that no matter how you configure your contraption, it will perform worse than if you simply didn't induce any current into a secondary in the first place.

The Chris Sykes PDF showed a test on page 13 and 14 where a magnetic field slowed current by a very measurable amount in copper wire. His test proves DLE is more then a just a core effect and involves the coil as well.

Anyone interested in prolonging the acceleration effect beyond what the diode coil can deliver can simply turn a thumb screw by hand.

Inductors slow the propagation of currents quite effectively.  They do that by conforming to Lenz without any delay at all.

The test shows that the presence of a magnetic field slows the current in an inductor more then the inductor slows the current in the abscence of the field. It dosen't sound like you even took time to look at the test. You're just parroting some more drill work.

It is not that difficult to change the bias on an inductor so as to change where it operates on its B-H curve.  Magnetic amplifiers were all the rage a century ago.

@MarkE,

Why do you have a problem understanding that a magnet rotor might travel at a speed fast enough to beat the opposite field formed by the approaching magnet in the output coil enough to reverse the drag effect and get a push instead? You should also be able to understand how a magnet core in an output coil would retard the efficiency of the coil, and make it easier for the rotor magnet to speed past TDC. What's your problem with understanding that?

Synchro1 the problem is a simple one of energy balance:  Energy is borrowed from one process, passed through a number of lossy processes and the balance is supplied back to the original process.  The result is by definition always lossy.  In order to be able to put more energy back than your original process borrows, you have to get an energy gain somewhere along the way.  Until and if someone finds such an overunity intermediary process, there is no hope of the overall process even reaching break even.

Where's the answers to the two simple questions I asked you?

We have to compare what you say with the kind of test results reported by reputable people like JLN:

"When the LOAD IS CONNECTED the RPM speed is DOUBLED and the INPUT POWER DROPS dramatically".

Isn't it amazing how much more efficient an inefficient thing can become when one reduces the inefficiency?  You are still stuck with the same fundamental problem:  Finding more energy at the output of any of the intermediary processes than at the inputs.  Alas, it is not to be.

@MarkE,

Take a look at this video:

https://www.youtube.com/watch?v=1ttm13AyiMs

What you see taking place in this video is very close to what output coil DLE achieves.

How do you measure the force on a piezo crystal exerted by the permanent pressure of a screw that's tightened down on it? The crystal will generate electrical power from the force of the mechanical pressure exerted by the screw, but there's no longer any external input. I want you to apply this thought to the video.

Piezo strain sensors have been around for decades and decades.

What did you get from the video? I'm reporting bursts of acceleration on the order of 25k over a matter of seconds!

Man can squeeze a piezo the same way. Got it?
