How Steorn Works

[terry1094]

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.
