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 :P ( 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 :P 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.

allcanadian, it redirects the field such that they direct back towards itself i believe... so afaik there should be no need to rotate anything... shielding is stypically used in stationary objects to stop a permanent magnet (such as for stereo / sound equipment) from interfering with other electronic parts...

yes the shield is "c" shaped in the patent,the north pole lets say enters the inner portion of the C and exits to the south pole through the legs of the "c' shield.

BTW I don't think the design on steornquest is quite right...

If you rotated the solenoid so it was perpendicular to the rotor , it would probably be better off...

As it is, the magnetic field will still exit from the bottom magnet when the shield is in the 'off' position... the only way that I see is to move down rather than back..

This will even still have a magnetic attraction against the rotor, which is why I had  4 LEMA's in my design, in order to provide a more direct attraction towards the next quarter rotation.

*EDITED* 4 LEMAs

Hmm... I am going to re-read the patent. If we are not talking about magnetic shielding but just re-directing the flux then cound't another permanent magnet be positioned somewhere near the stator magnets to allow for the same effect?

I'm just trying to work out something in my mind that allows for the concept of the LEMA (redirecting the flux) to mesh with Sean's statements that the overunity technology has nothing to do with the LEMA.

Of course, even if they have advanced beyond the LEMA and are using another setup with only permanent magnets it would still be a good idea to build and test the LEMA ourselves.

I actually tried the actuator setup, three neo magnets 1" round -1/2 " apart on 4" x 2" metal strip-"C" shaped shield over the center magnet-shield attached to wood disc on ball bearings. So Im not making this up, when the magnets are all north or south face up and the right distance apart the shield moves from one magnet to the other with very little force, if however you try to move the shield away from the magnets there is a strong attractive force. that is the secret just as wesly gary said 50years ago, do not remove the switching element from the magnetic field.

basically.. from what I gather...

the magnetic attraction is stronger the further you move from a magnet... this is due to the flux (the amount of field lines travelling through a surface),  

By adding the 'balancing' magnet, the shield can be moved without altering the flux
no matter where the shield moves, the amount of covered magnetic material averages out to being 1 magnet)..  Thus the only force to move the shield, is due to the friction on the rails, gravity.  The friction is probably still pretty high, as the attractive force between 1 magnet and the shield ( the force its attracted to the shield at ANY position ) is normal to the movement...  but its better than just moving directly away from the magnet... ( like your sliding a magnet on the fridge analogy)

great to know allcanadian.. thats reassuring..

This might actually work then, ill have to see if i can get some magnets....

the problem still exists that the bottom magnet ( when the shield is in the 'off' position ) will still exert a force on the other magnets on the rotor...

another magnet needs to exist (from what I can see) to overcome this... I came up with 4 magnets on the outside each at 90degrees of the rotors rotation... I'm not sure if thats ideal or not..

Maybe I can explain the setup better, let's say the actuator is laying horizontally, three magnets on a metal plate on a table. The shield is "C" shaped-free to move along the magnets on a rail or arrange the magnets in an arc so the shield can move over the magnets in an arc, because the shield is mounted to a thin disk.If you mounted a rotor with magnets on it over one of the end magnets of the actuator. then as the shield is moved the end magnet under the rotor is covered then uncovered moving the rotor. the question is you are still only using half of the actuator. what about the other end magnet not used? there are 3 magnets in the actuator why not use both end magnets that are covered then uncovered? so you use 2 rotors,one over each end magnet, the magnets on the rotor are offset so as the shield is moved back and forth one magnet on the rotor is always being attracted. the middle magnet just sits there and balances the forces on the shield so it moves easily.

Here is another twist on this,why use a rotor at all? If in fact the shield can be moved back and forth with very little effort,which I have verified it does. Then why not mount a "C" shaped coil around both end magnets. When the end magnet is covered it's field does not enter the "C" shaped coil,when the shield is moved the magnet is uncovered and the field enters the "C" coil.One of the coils on one end charges a capacitor that switches a solenoid that moves the shield, the other coil you pull power off of for use elsewhere. Why bother with a motor/generator setup at all,if you just want electricity?
just a thought

Interesting Idea, but its getting away from the steorn design.. and I think it may be worht looking into, however to stick to the thread topic,

I think that having 2 rotors could cause wierd field interraction 

I think our designs are similar though, (mine and the steornquest site), whereas mine uses 4 lema, with 1 magnet on the rotor, and steornquest uses 2 magnets on the rotor and 1 LEMA,

both should be easy to build, but sticking to steorn's description we shouldn't need a solenoid or any other electrical components..
