Hi Reade,

Thanks for the drawing, it worths a thousand words 

Quote... I think that some kind of rolling bearings to either side of the magnet so the shield slides just over but not touching would resist the attractive forces better.  I think that would scale better and allow for a very strong magnet. ...

Yes I understand and agree, otherwise the shaft + its bearings holding the shield piece should be made very robust to withstand the huge forces involved.

Maybe a U shaped shield could be also be considered, I think, also with rolling bearings.

I 'borrowed' the U shaped shield idea from the LEMA setup (Low energy magnetic actuator), see Steorn patent drawings here

you may have seen it.

Thanks again,

I hadn't seen that link from Steorn.  Very cool!  I wondered if magnets in a row like that would help slide the shield.  It looks like it.  I can't wait to hear Steorn's next announcement early next month.

Thanks Gyula.

My own experience with how close I was to getting the shield on/off so easily coupled with the fact that it looks like Steorn's using a similar approach actually makes me start to think they might not be a hoax after all.

You've probably seen this video of a guy trying to replicate Steorn's LEMA:

It's really good, especially at the end.  So now I'm getting really convinced of what Steorn's doing.  In Wikipedia it says Steorn claims that patent is not related to their big news but that would fit perfectly with trying to throw people off the trail.  Because if you can turn a permanent magnet on/off with less power than the exposed magnet can produce then that's all you need to prove you can make an over-unity device. 

Hi Reade,

You accidentaly gave the Steorn patent link instead of the video link.

Well, it is possible they deny on purpose that their device includes  the LEMA concept but I think it is a 50% chance. There are so many unknown magnetic phenomena to be explored...

In this Forum you can find several topics on Steorn, like this one dealing with the LEMA concept:
