RE: [Vo]: How Steorn Works
Remember SMOT? The ball was put in a position of high potential magnetic energy that's why it made it up the ramp back to the start. -Original Message- From: William Beaty [mailto:[EMAIL PROTECTED] Sent: 29 August 2006 23:16 To: vortex-l@eskimo.com Subject: Re: [Vo]: How Steorn Works On Tue, 29 Aug 2006, peatbog wrote: I thought that anything that blocked a magnet's attraction was also attracted to it, so that there is extra work needed to insert or remove the shield from between the magnets.

RE: [Vo]: How Steorn Works
Incorrect. Below saturation it will have a low reluctance and so form a preferential path for the flux. Above saturation it looks like air again. -Original Message- From: Terry Blanton [mailto:[EMAIL PROTECTED] Sent: 29 August 2006 22:20 To: vortex-l@eskimo.com Subject: Re: [Vo]: How Steorn Works On 8/29/06, peatbog [EMAIL PROTECTED] wrote: I thought that anything that blocked a magnet's attraction was also attracted to it, so that there is extra work needed to insert or remove the shield from between the magnets. Mumetal does not block the field. Once mumetal saturates the field is diverted around the mumetal. It distorts the field. Terry

At 01:48 pm 29/08/2006 -0400, you wrote: From Steve's interview and close examination of the test rig image, I believe I know how the Steorn machine works. Note the large aluminum disk has what appears to be four threaded holes around it's perimeter. Also note that to the left of the disk are threaded holes in the supporting mechanism. I believe four NeFeBo magnets are attached to the disk in 90 degree increments and one Neo is attached to the supporting mechanism. A mumetal shield is arranged with a camming device such that when the disk is rotated by hand, the attractive force of the magnets adds momentum to the disk. When the rotor magnet is nearest the stator magnet, the cam drops the shield between the magnets sending the disk over the sticky point. The cam then lifts the shield and the next magnet approaches. They had to convince themselves that they could generate energy so a worm gear is added to the drive shaft. This drives a large pulley which is belted to a small pulley. The mechanical energy drives a generator which subsequently drives a motor. In a similar gear/pully arrangement they drive another shaft. If you look in the foreground of that shaft you will see a mechanical brake which can add a load to the driven shaft using the brass screw. Speed sensors are on the ends of each shaft. Just my opinion, I could be wrong. Terry Sounds good to me Terry. Well done mate. 8-) Frank I'm sending this to you direct - as well as Vort in case Vort don't get through.

Terry I thought that anything that blocked a magnet's attraction was also attracted to it, so that there is extra work needed to insert or remove the shield from between the magnets.

If so, then perhaps the conductive parts create a large inductive drag, which keeps things from spinning fast. If the effect is genuine, then plastic parts and nonconductor supermagnets (composite rubber supermagnets) might make a big difference. (( ( ( ( ((O)) ) ) ) ))) William J.

I was going to suggest to Sean that his rotor disk be made of PVC. However, he seems to be doing fine without my help. :-) Terry
