STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

I don't totally agree with this, exnihiloest, with all respect.
Steorn's coils are not energized with both positive and negative currents, as far as they publicly explained.
They show only positive currents.
Thus there will be no core losses that related to the B-H cycle, simply because they don't full cycle the cores.
...

When the coil is pulsed, the rotating magnet moves away. It is not simply a question of losses in B-H cycle. It is a question of work: the coil current do work to align the magnetic domains of the core against the direction that the permanent magnet want impose. This also is viewed as a resistance from the pulse generator.

This also is viewed as a resistance from the pulse generator.

Coming from earlier positive pulses, the domains are already alligned for a great deal. This is why there is a magnetic power B_R left in the core. Assuming Steorn is using Metglas cores, the difference between B_R en B_sat is 0.57 - 0.43T, so roughly 80% is still aligned before a new pulse is applied.
The remaining 20% is not perse converted in heat while being aligned. Most part is returned to the coil after powering the coil.
Compare them with a spring that is loaded and unloaded after releasing the power to load them.

This is easy to test by removing the rotor and pulsing the coil alone. Have you tested it, or is it only a theory ?

If the "drag" presents itself as a resistance, the current will decrease in presence of magnets or the current pulse shape will be different. Hope fully I will be able to do this test soon, but I have no idea why other replicators haven't touched it yet. Its a tell tale sign of OU.

The transformer being used by Omnibus is nothing special, no special material needed and should be available easily. Its a 1K/8 ohm audio output transformer, used in matching the impedance of speakers with audio amp for max power output.

All other transformers should also show the same behavior in my opinion. I will do some experiments in near future when the measuring equipment is there.

That's correct. I've been testing four or five different types of transformers and the effect I'm reporting is seen in several of them. Probably those that didn't show what appears as OU will show OU at appropriate conditions too. The point here is to study one and the same easily obtainable transformer (at least in the USA) so that we can compare notes, not that it's anything special. That effect, if real, is trivially present in transformer type devices but hasn't been noticed so far.
