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

In the Steorn demo talk 2009-12-19 they show a scope shot of the current & voltage. Has anyone been able to tell how much current it is? I'm not familiar with that scope model.

We can see that the current rises almost instantly, so nearly 100% of the entire pulse is just pure resistance losses. So why didn't Steorn use much thicker wire in their toroid? In their other video titled "Steorn Orbo Technology Launch 2009" we can see that the separation distance between the magnets and toroid wires is relatively far. So they could have used wire that's like 10 times thicker.

Woohoo!!!  I finally got a little time to get my motor running.  It's running really well so far, but I have alot of tuning to do.  It's just been so frustrating working so many hours at my job, I've been inching my way through the replication.  My first test run, just to see if it would work, is using a little cellphone charger adapter to power it.  It is running about 800 rpm, with 5.3 volts and 90 ma...  That's acceptable for me to go ahead and finish mounting things, and tune it in.  I'm only using a reed switch at the moment, because that's all I have.  And I don't even have any transistors or recovery circuit hooked up yet.  It was just a quick spin up to see if I could start mounting things down a bit.  With only one steel washer toroid, and 1500 turns of #26, it's running...  I'll get a video and pictures up in the next day or so, and start helping out a bit more with another hands on replication to poke around at!

Does anyone have a setup running like Steorn's with dual magnets, one above the other? If the top magnet polarity is opposite of the bottom magnet, then that's a whole lot more cogging, but maybe that's why Steorn is using relays for the toroid current.

It's cool to see how little current & power we can get a motor to run on, but maybe that's the opposite direction to go in terms of amplifying the excess energy effect.

Yup, we do now!   I built mine so I can easily change all the parameters to test.  Here's some pics of it so far.  It's not tuned, but so far there is no vibration and running very smooth.  Except of course that it's not hooked up right yet, lol...  I'll get to that tomorrow night after work I hope!

Paul,
1) I think they are the same polarity, and someone suggested that the two magnets presented a more homogeneous mag-fld to the coil.
2) I think your guess is as good as any! IMHO, I think a first attempt at self-runner would try to minimize PowerIn, and then use a very small generator that only produced PowerIn + some padding (10%?) for losses...

If one had a torque-meter, and they do exist but are quite expensive, one would optimize the system to maximize torque with minimum power in... but since most here are working on 'spare change', they have to go about it in a round-about way.
