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

[LarryC]

The coil is 1.4 Ohms primary and secondary with a ferrite core. Don't know the inductance, no meter. The scope traces used a .1 Ohm resister to display the current. Used a pulse generator as input.

Works as theorized, the only surprise was the induction curve with no secondary short increased when the magnet was half under the toroid, little less when directly under. But it fluctuated when moving in and out. Moving the magnet around when the secondary was shorted had no effect.

IMG_0249 - no short, magnet half under the toroid. Good induction curves.

IMG_0250 - no short, no magnet. Less induction curves, but still there.

IMG_0251 - secondary shorted, no magnet. No induction curves.

IMG_0252 - secondary shorted, magnet half under the toroid. No induction curves.

IMG_0253 - Coil, the black cable was used to short the secondary. The magnet was placed under the 1/4" plywood for testing.

Anyone who has Java enabled on their browser can play around with the Ising magnetic simulations, a well known and popular way to simulating magnetic materials. Give your browser ~ 30 seconds to get the applet going. You'll see a large window. Change the "disorder" to a square loop core, ~ 2.3. Click "Generate loop." Then click on BH curve to move the applied field. Moving the field back and forth from full to 0 to full to 0, etc. matches the core seen in the Steorn power in & out scope plots. You'll see how it shows that most of the energy stored in inductance in the Steorn setup can be captured back, as shown in the Steorn scope integrated power plots.

For getting down to the bare minimum voltage needed and max current, it would seem that shorting the secondary is indeed the way to go.  But... My toroid STILL will not saturate.  (see pic below)  So I will add more winds in series with my 20 awg of 26 awg.  I have also ordered Jimboot and ossies toroid.

Good try. But just some comments.

I don't know if full saturation is used in Orbo, as the flux return for power increase in the upper end of a Core Saturation curve is constanly reducing until full saturation.

That's a lot of magnets strung together in the jar. All together they produce almost the same force as one long magnet. The glass thickness seems thinner than the normal distance used in Orbo. My magnet drop test worked correctly using a 3/16" distance.

Also, I used 26 awg, same length, for primary and secondary in my toroid. Mainly because I don't know how to properly balance wire size and length when using different sizes.

Hi Larry,

Very good observations.  I am now winding my primary with 26 awg, same as my secondary.  I just put it into series with the 20 awg. basically I didn't feel like unwinding it. 

Some more winding should get me there... LOL

Thanks!

Tinselkoala's latest video, Biased Magnet Orbette number 51, is an excellent proof of concept demo for the idea I posted a few pages back. TK's Orbette RPMs rise around 50% while his input current drops with the attachment of magnets of opposite polarity behind his flux blocker toroids. Truly awesome results!
