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

[Staffman]

@ All

I've been doing some calculating and I'm getting confused. Steorn was saying that they are getting out more energy with the change in permeability. Where E = LI^2. Simple enough concept at first glance. Cool! Well, here is where I'm getting confused. If the inductance increases, the reactance also increases. If the reactance increases, shouldn't the current decrease before the toroid coil is cut off? Where I = V/R.  Is Steorn saying that in their setup, voltage and current remain steady and reactance is no problem? I know that is what they are claiming, but this is confusing when trying to calculate this stuff and follow the energy flow. If someone could help clarify this, it would be greatly appreciated.

Edit: I think I know where I'm getting confused, there is a DC component. You have a changing voltage on the rise and fall, but in between there is DC. But would the collapse of the field follow the reactance of the coil?

@Airstriker:
Regarding the coil orientation in JLN's video, you're right. They only used this orientation in the first Orbo demo. However, the motor did work in said demo. What I'm wondering though is if the effect is the same. They are also claiming that the CEMF in an open loop coil won't be representative of a powered/saturated coil, so I don't really know what this tells us about JLN's measurements.

@gravityblock:
I don't know why you'd even want a field collapse without "cutting" the wires? It's just the inverse action of building the field in the first place. The energy you put into the coil to build the field will be recovered when the field collapses. This isn't a bad thing. If you eliminate this you'd effectively destroy energy and we wouldn't want that. Also, as it's just the inverse action to building the field you'd never be able to build the field in the first place if somehow metglas shields the field in the core from the wire. I think their first demo even showed the inductive kick-back pretty clearly.

Hi all.
I thought I might be able to clear up the arguement between Striker and GravityB.

The truth is that they are both correct.
When you turn off the current, the core does hold alot but you also get a huge back voltage spike.

For instance:
Take an iron toroid in 2 halves each with a winding on them.
Now magnetize the two halves together to form a full toroid.
When you disconnect the current you get a back spike but the two halves remain firmly magnetized together.
You can see me doing it in a similar way here.

If I put a rectum frier    on the output of those coils and pulse them...I can charge up caps to over 300 volts. (If I do it at the A time)
The Metglas core would give me even more! And I can run a motor at the same time.
I can charge the cap with or without using a keeper on my electromagnet.
So no matter if the magnetic circuit is closed or broken you still get a back spike when you disconnect the current from the coils.
When there is a closed magnetic circuit then it will remain closed until something breaks it, but you still get a large voltage back spike from the coils.
Take a look at this clip I made a while back too.

It will help with your visualisations.

Awesome Bruce!  btw, if you happen to find the toroid diameter and also the separation distance between the magnets & toroid then I'd greatly appreciate it!

As far as the gap between magnets and coil, I think that is going to have to be adjustable for sure.  It will depend on both the toroid material, and the strength of the magnets.  But here are a couple pics I dug up that show the gap being fairly large.  My guess is near 1/2" or so.  But that does not mean all their demo's are the same gap, same magnets, or even same core material.  We just sorta have to assume they are using all similar materials.

"I think you guys should watch this video from Bedini: http://www.youtube.com/watch?v=NYh8W3_EZjc

He clearly states what I said a few pages before about the A field. I am more convinced now that that is the case based on the speed increase from some replicators here.

Fausto. "


Hey all,

Being a Noob, I cannot get my head around how this works.

Would some of you magno-tech savvy guys help me understand, if there is no core, like I have setup with my pinball machine coils, where does the attraction come from that makes this motor spin ?

There is no core, the coils are wound around a plastic former.

I know I must be missing something very fundamental.

Kind Regards, Penno
