How Steorn Works
« on: August 29, 2006, 07:51:46 PM »
From interviews 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.

Do you have any speculation as to how the shield helps with overunity? I see how it would get the rotor past the sticky spot, but isn't that undone by the work needed to move the shield in and out of place?

Steorn is being talked about so much, it must have the interest of the people here.

I'm disappointed that I'm the only one who has commented on Terry1094's analysis of the Steorn machine. With all of the talented builders that frequent this list, I'd hope a few would attempt to replicate the design he describes, or point out why it can't work. It seems simple even to me: 4 magnets on the periphery of a disk, another, stator, magnet, and a cam to move a shield in and out of the path between the stator and rotor.

The basic principle is probably very simular to

It was my understanding that the Steorn device was all permanent magnet and some mechanical to shift the shield at the appropiate time?  It is hard to tell since very little detail is known.

It's easy to calculate how much energy is required to raise the shield.  It is more of a challenge to calculate the mechanical energy output of the motor.  I have been working with Paul Sprain on his magnetic motor which is similar in concept but uses and electromagnet to get over the "sticky spot" and know the difficulty in proving OU.  Paul spent over $10k having a custom built torque sensor made for his machine.

I'd love to build one but I am having trouble finding a small mumetal sample that I can afford on my hobby budget.  Seems that the price of nickel has gone through the roof.

Come on, guys.  I posted the above back in the middle of April - think about it...

Absolutely incredible interview. Seems they got it, congrats to them.

They made it fool-proof in their demand of science to test their systems.

Now, lets see if they live or if the scientists will actually publish the results.....

After reading thier patent, it is EASY to see why the system will work...

I hope you're correct!  If Steorn turns out like all the others and just fade away then we cannot allow this to discourage any "free energy" research.

Publish.

As part of our formation of the new association, I have designed a toy that could be used as a proof of concept that relies on a low energy magnetic actuator (LEMA) to demonstrate the energy stored in magnets.  I would like to, before I continue, get some more feedback on Steorn's LEMA patent, like how much energy would be required to move the shield, as compared to moving the shield without the magnets present.  At the moment, I cannot find anything that presents test results of the low energy feature of this actuator.  I know that someone on the steorn forum posted their "LEMA" out of hard drive parts: http://www.steorn.net/forum/comments.php?DiscussionID=13112&page=3#Item_25, but it's a bit different than Steorn's LEMA, and he said that a feather could move the shield.

I would like though, some actual test results.  I haven't found any references that have built specifically Steorn's LEMA nor any tests.  If I had the resources, I would have built one already and posted the test results.

The temporary website of the new association is here until the poll for the new name ends on Sept. 30, 2006.

Mechanical shielding or field mitigation at the sticky point is nothing new. The torbay motor is a similar concept, it moves the magnet itself instead of placing a shield in front of it.

Mumetal shields are widely used in hdd's and I have a fair amount of it in my garage, salvaged from hard drives. It does do a really good job of shielding, enough to get it past the sticky point for sure, but it's not light. Moving it with a feather would be a feat of engineering.

Hi gn0stik,
What part of the harddrive are you refering to as a shield? the casing?
Thanks
