Partnered Output Coils - Free Energy

[TinselKoala]

Ah, you beat me to it by seconds....

Plus I was nice enough to TinyURL it to boot!  Sucka!

I have taken the liberty to summarize the thread in a "benchmark" post:

Key points for those attempting a replication of the partnered coil device of EMJunkie (Chris Sykes)

Note: this is my interpretation after having followed the thread carefully and pressed Chris for the parts list etc.
==============================================================================

Use a deflection transistor such as 2SD1555 or equivalent for Q1, not a FET. The transistor has a built in damper diode.

Use an N3K FSF10A40 diode or equivalent for the catch diode D1.

Use the core from a flyback transformer, with a small gap in the leg where the cores are placed. (Chris says any flyback core will work)

Use 0.39mH spool wound coils (layer wound) that fit snugly onto the ferrite core legs. The 0.39mH is measured without the core, in free air.

Inductance will be much higher when slipped onto the core. (Chris used speaker crossover inductors for all three)

The center core is L1. The outer cores are L2, L3 which are wired out of phase.

The power supply for the circuit will be around 6.7 volts

The output resistor is a 10 ohm wire wound, as such it will have some inductance.

Use a Function Generator to drive the transistor at 1.732 kHz, 50% duty cycle. The drive voltage from the FG must be carefully adjusted so that the transistor comes out of saturation early in the drive cycle, at about 10 to 15% as seen in the scope shots.

This adjustment of drive voltage holds a DC current on the core for the remainder of the drive cycle. (this may be needed or will just waste power...my opinion)

Full flyback effect occurs when the zero level drive signal shuts off the transistor (at the end of the positive drive period.)

A 555 timer may be used for drive in place of a Function Generator, but current to the base of the transistor must be limited with a potentiometer to properly set up the low drive current.

With proper adjustment of the FG drive level, you will observe large ringing spikes during the full turnoff of the transistor, at the end of the positive drive period, as measured at the collector of the transistor.

A full assessment of power input vs power dissipated by all components including the load resistor would be required to verify a COP=1.7 as claimed by EMJunkie

I encourage Chris to comment or correct any errors in this post, so that replications may be closer to his device.

This is a rudimentary demonstration of what a post that makes a claim should look like at the outset. Also power measurements should be shown using the test points on the schematic for reference. Scope shots should also be referenced to test points, and a scope ground reference for each scope shot.

Thank you (MileHigh, TinselKoala, MarkE) for the answer.

I have this LCR meter and tried to measure Z for a coil (with Ferrite core)  I have:

at 100 Hz --> Z = 3.4 Ohm

at 1 kHz --> Z = 17 Ohm

at 10 kHz --> Z = 170 Ohm

Does this look right?

A speaker would have roughly the same Z between 100 Hz and 2 kHz, but a coil (with core) goes up in impedance rapidly with increasing frequency?

   Cap-z-ro,
              you're doing Chris and others a disservice with your ramblings, Chris has
probably learned more off of people on this forum than he has grasped for himself
in years.
       Chris comes over as a puerile whinger but he could change, join in and LEARN,
but he won't. It's his life, his decision , he can do what he wants!
          John.
