Thane Heins Perepiteia.

OK, now we've settled this I can tell you what the real experiment is/was.

Firstly, it's clear to anyone that both the perepeteia and the bi-toroid transformer thing are both BS: and they're BS in exactly the same, transparent way. Build a weird device that wastes lots of power, do something extra weird to it that causes it to waste less power, act surprised, and then claim that it's an astounding breakthrough.

PB

I think PB fell for it hook, line and sinker... hell, she/he/it/whatever even swallowed the frickin' pole.  Thane, think you ought to invoice PB for the fishin' pole.  Shouldn't we have to pay to have this much fun?

Thane, might want to throw this one back in... let Darwin take care of things.

And regarding the sociology/psychology experiment... kinda makes you wonder who is the 'lab rat' and who is the scientist?

Speaking of catching Carp. A lot of US lakes hold Carp rodeos and feed the catch to the animals. Mainly because the foul tasting fish eats the game fish eggs. The best bait to use is strawberry corn. Which is created by adding a package of strawberry Kool-Aid to a can of corn and let it sit overnight. I'm serious, the Carp will come from miles around when used as bait.

Is that why Thane warns people not to drink PB Kool-Aid?

In an open system, there is magnetic potential leakage into the environment. But this is offset by the characteristic phase changing of counter MMF during nominal and excess loading, which reduces the impact of breaking associated with Lenz's law.

Yes, that's true -- I have recently observed it in some experiments, and I'm quite surprised that you know it!

It has been my experience so far, however, that the phase change in the counter MMF is only made possible by this potential leakage (more precisely, it appears that magnetization diffuses into ferromagnetic materials), and that this phase change can mitigate the energy loss, but not entirely cancel it.

In an open system experiment, place incremental loads on the coils, and you will see that the breaking effect is greater when with loads are less than nominal, and  decreases as the load approaches and passes nominal loading through to short circuit. With low impedance coils, at very high speeds, a short circuit will present almost the same loading on the driver motor as an open circuit. At all times, actual breaking for a given power output will be less in an open system.

Yes, I have observed this as well, although not the requirement for "low impedance coils".  However, it has again been my experience that these open systems have extra losses that make this possible, and the power out is never enough to make up for the braking effect that remains.

This is all consistent with what I said about how Thane gets his acceleration.

P.S. Remember, I've always only been talking about a completely open magnetic generating system.

Thane, if you're magnets are inserted into metal cups then you have a semi closed system, because you are redirecting the flux from the rear of the magnet up to the circumference edge of the magnet pole facing the coils. Penetration of the flux from the open magnet pole end to the coil core will be shallow, as it follows the easiest path through the face of the coil core to the opposite pole at the external cup around its circumference.

This is one possibillity why you haven't seen similar results to mine. And perhaps part of the reason your results have been intruiging. No doubt there may be other differing parameters as well. I've already posted links on this thread to my previous experiments twice. So no need to again. I acknowledge that, whilst I believe you are dealing with the same effect as that which I have previously studied, there is still a possibility that it is not the same, or , if it is the same, it's manifestation is different due to any number of variations between our system parameters.

Hi Hoptoad,

It is a semi closed system with metal cups. This has always intrigued me. Do you have ideas on how that dynamic would play out? It seems that N-S would fight until the opposite face loses. My question is would that be a slow flux loss based on face percentage or an extended battle causing a quick flux release at certain coil charge value? In case you missed this fact in all the clutter, the core/magnet gap is much larger then in a convention motor/generator.

Thanks,
Larry

PS- Thanks adlep.

@Mr.Entropy,

I would also appreciate your comments on my question.

Thanks,

The difference between iron and steel is: when steel is magnetized it stays magnetized.
But iron only remains magnetized until the magnetic field is removed.
If the core of a transformer remains magnetic after the current is turned off that would resist the
transformer action. That is why it's important to get soft iron for the core.
Otherwise it's like winding a coil around a magnet.
My understanding for using welding rods to make cores is because they are a source of soft iron.
We can buy steel wire or rod for a lot less then the price of welding rods.

I noticed the rod chemistry on that site and it says E7014 rods have a low carbon content C 0.06.
I believe it's the carbon content that makes steel stay magnetized.
Anyone have any more info on this.
I though I seen someone else on this forum using welding rods, on another thread.
