If you armchair skeptics spent as much time reading the Steorn forum or Overunity.com, as guessing and speculating and accusing here, you just might have a different opinion. Sean is responding to questions on the Steorn Forum, and many guys on the Steorn thread on Overunity.com are making very good progress towards a replication. If you actually wish to discuss this from an informed position, I suggest you start reading... http://www.overunity.com/index.php?topic=8411.1740
Attached is a graph that JLNaudin has done, so I think its an objective result. He shows that the inductance of the coils changes from a low of 185mH to a high of 962mH just by the rotor magnets moving past the toroidal coil... Sean has mentioned this effect, so he's not hiding some KEY elements of the design!!! No BEMF is also an essential effect, and has been replicated now by JLN, as can be seen here... http://jnaudin.free.fr/steorn/indexen.htm and about 2/3rds of the way down the page look for... TEST 3: Canceling the Back EMF in the toroïdal stator coils This is ANOTHER key element WHICH Sean HAS ALSO MENTIONED, to quote him, "...and by very careful and specific positioning of the coils..." But then, you guys wouldn't know that since you prefer to spend your valuable time speculating here instead of trying to educate yourselves. This webpage also has a graph of coil inductance vs rotor magnet position... So, the inductance is LOW when you energize the coil, and ~5+ times higher inductance when the current is turned off and the field collapses... I think you geniuses should be able to figure out the consequences of that! :-) I STRONGLY suggest that you stop speculation and start education! They will be allowing people in to make measurements with their OWN instruments (more than I can say for 99% of the 'inventors' out there), and a German company will be doing the calorimetry. I still don't know if its overunity or not, but they are much more open than nearly all OU inventors that I've seen in 25+ years... -Mark -----Original Message----- From: Terry Blanton [mailto:hohlr...@gmail.com] Sent: Friday, January 15, 2010 11:21 AM To: vortex-l@eskimo.com Subject: Re: [Vo]:Back EMF: Sean may be right On Fri, Jan 15, 2010 at 1:18 PM, Stephen A.

I don't recall that we know anything about the core except it is present in demo 2 Orbo and absent in demo 2 Pulse Motor. I don't recall anyone saying the core was magnetic, only ferromagnetic. Of course, it could become magnetic due to remanence. Or it could be a high permeability metal with lots of nickel and little remanence, a super-mumetal. T No virus found in this incoming message.
