The Steorn Permanent Magnet Motor Replication Project: It's FLUX time.

To the best of my understanding, no

the whole point of the shielding would be defeated at that point

The idea is that it can interfere with the magnetic fields by becoming magnetized easily in the proximity, but it does not take permanent magnetization... unless someone more qualified can correct me?

that said, I don't think that a solenoid method needs to be used as on steornquests' design... I think the shielding can be done purely mechanically... thus avoiding the whole issue of having to plug in your free energy machine ( A more impressive machine should run with no wires)

Kent,

If the Steorn overunity devices uses the LEMA (saying maybe because Sean McCarthy denies it) then I hope that a mechanical way of moving the shield can be found.

However, I would like to know if such a shield would lose it's effectiveness after a period of time. I have heard that Neomydium magnets can keep their strength for a long period of time (thousands of years) but how long would various materials for the LEMA remain functional and un-magnetized?

Nostradom,

Yes, that is what he said. But if no LEMA device is being used and only permanent magnets then that arrangment is just not going to work, because it's obviously been tried before. The problem is that in such a configuration you can indeed create a force to move the rotor/wheel forward. But then at some point when the magnet attached to the rotor comes back around the whole thing stops. This is due to a sticky point.

Basically, there are two possibilities. Either the LEMA is used for OU or some special configuration of magnets that allows the rotor to get by the sticky point. It's one or the other.

Vorlon,
Don't quote me on it but afaik the shielding will last a long time,  if it didn't, then the shield wouldnt be a shield.  


Nostradamus:
That diagram is a good way to show the sticky point people talk about... My belief is that steorn uses the LEMA to allow momentum to carry the magnet past that point.. (block magnetic fields so that it can get past that point where its moving opposing to the field lines), then open the shield once movement is again in line with the magnetic field lines.

The diagram I showed earlier, follows the same principal, using lemas, and 1 magnet, the 4 gears control the LEMA similarly to the solenoid shown, timed such that only 1 is 'open' fully at any point in time, the other lema's open and close as the magnet moves around..

Not sure if i'm totally off base though may have to build it at some point..

The lema itself wouldnt be too hard to build.

Kent I think if the shield never leaves the magnetic field of the actuator it does not matter if it is magnetized. The shield rediects the field it does not block it. If the shield becomes magnetized you flip the magnetic array every 20 minutes, put the magnets on a spindle or shaft-problem solved.
