Kromrey Disclosure! Bedini SG - Beyond the Advanced Handbook by Peter Lindemann

Yes, I have seen some of the delayed Lenz demonstrations at very high rpm. But Kromrey's test data shows quite low rpm's with his large machine. Also, JB's original large replication shows loud magnetostriction noise even without a load, i.e. open circuit condition, and that at medium to low rpm's. So windings are not a factor at that point.

I think that loud noise is a real key indication for the desired effect. The windings may not be critical or unusual, especially after looking at the small JB unit that Aaron demonstrated on video. Not much room for windings there.

I don't understand it. I know it has a hole drilled in the center of the rotor
so the wire from one coil can slip thru and the other coil can be wound.

So I guess a reversal takes place? I wonder how it speeds up? Maybe
the coil is so short that the induction is nothing.

The two rotors are connected via a hole under the slip rings. All rotor coils are connected in phase adding, such that the peak voltage is maximized by series addition of the four individual EMF's.

Having played with this for a while now, I am convinced (through process of elimination) that the Kromrey Effect, which definitely includes cold electricity effects, must be related to eddy current phenomena and the attendant loud magnetostriction, despite the loss of efficiency this usually implies. None of the Delayed Lenz's Law demonstrations, or the coil shorting demonstrations, are showing anything in that regard. Bypassing Lenz is a good thing, but the Kromrey goes beyond just that.

Magnetostriction

I have been researching magnetostriction, starting with the usual mainstream sources, in a quest for what might be the best material for the Kromrey magnetics. While we won't know what exactly JB used in his machines, I am thinking it must be soft, low carbon iron, probably annealed, maybe nothing very exotic. Higher Si content increases resistivity, but is that desired? Not sure.

Here is a non-mainstream view on magnetostriction:

Kromrey Noise

Here is an audio clip of JB's Kromrey demonstration at the 1984 LA "Town Hall" meeting. This was a larger machine running a string of incandescents as a load, through very thin wire which stays cool. The unit was turned by a standard 3600rpm AC induction motor. You will hear a brief section of the Kromrey running under load, with JB having to raise his voice into the mic to be heard over it. Then he will disconnect the load, and the Kromrey will run open circuit. This creates a strong back torque which will then stall the drive motor, and it drops to zero rpm at the end.

The important thing here is that the loud magnetostriction sound is present even as the rpms drop far below the operating speed, and the windings are drawing no current. This means, IMHO, that the activity which generates the cold electricity shown in the demo is present in the cores of the Kromrey whether tapped by windings or not. It is at least in part dependent on how the magnetic domains shift and twist as the rotors go in and out of register with the poles.

I am looking at some low carbon iron to use for the next tests. This is one reasonably priced candidate:

There is a supplier of soft iron rods on eBay, but only of small diameter. There are more pure iron rods available, but they very costly.

Some specifically magnetic alloys are out there, but in industrial quantity only, apparently. For instance, Turfenol-D has very high magnetostriction properties, but is hugely expensive. I am hoping the above rods, if annealed, will show some activity. Open to suggestions.
