Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

I'm fully aware of that. I use spice sims extensively prior to building most of my circuits. Spice needs  to know resistance.

I'm not going to get into the physics of this tech, yet, but it's very difficult to build a self-runner unless one uses low loss cores. Anyhow I just thought it would be more meaningful to people to specify resistance, which causes loss. It's the parameter I would be prefer to see.

Additionally it helps to know the cores Z, X, and R curve. The core I showed in photo is fairly linear up to at least 11MHz with respect to R. IOW, twice the frequency will double R. Although to my surprise it appears to have a "sweet spot" around 330KHz where R is significantly less.

I don't know what the heck you are measuring but resistance does not change with frequency.

Impedance changes with frequency.

Have you seen a self-runner?  If not, then how do you know you have to have a low loss core to attain one?

Respectfully,
Carroll

Hey I think we have our wires crossed somewhere. As the frequency increases the core will almost always lag more which is seen as increased resistance in the circuit. You can verify this in FEMM or better yet real life if one is careful and knows what they're doing. :)

Some measurements taken with the core shown a few posts ago

@48.3KHz 2.3uH 0.125Ohm (4.7uF(big square red, WIMA 63V))
@183.8KHz 2.3uH 0.36ohm (330nF(large green))
@331KHz 2.3uH 0.19ohm (.1uF(big blue, verified on WIMA .1uF))
@912KHz 3.0uH 1.8ohm (10nF(WIMA red))
@5.4MHz 0.4uH 12.5ohm (2.2nF)
@11.58MHz 0.4uH 24.2ohm (470pF(burgundy mica))

Circuit is the coil in series with a cap and a 0.05 ohm resistor, connected to a signal gen. Voltage is measured across the signal gen and the 0.05 R. The signal gen is adjust to resonance, and the core resistance is calculated as

Rcore = Vs / (Vr / R) - R

where Vs is signal gen voltage, Vr is voltage across R (0.05 ohms), R is 0.05 ohm resistor

You'll  most likely need to view the voltages or at least Vr on a spectrum analyzer unless Vr is high enough above noise to an accurate reading.

Vr / R is the circuit current.

Vs / (Vr / R) is the total resistance.

It's nice to see that someone actually knows just how to build an electronic self running free energy device and what circuit elements and parameters are important in doing so.

I'll repeat Carroll's question, which you didn't answer. Maybe you just missed it:

QuoteHave you seen a self-runner?  If not, then how do you know you have to have a low loss core to attain one?


So, TR, when will we be seeing _your_ self runner demonstrated?
