Energy Generation Apparatus and methods based upon magnetic flux switching.

Looks to me these guys are quoting a working unit or is it wishfull thinking.

One of the better reads,  looks like they did some homework. I'm surprised the patent was granted. Will have to check the prior art referenced. These things look good on paper, the proof would be a working unit. This should be simple to replicate. More interesting than a lot of patents out there.

I think the most important part of these patents is the methods shown for redirecting the magnetic force.

They are known to actually work and are not related to methods used by some well known (and many not well known) OU researchers. Yes, these folks did there homework. They understand that a flux link cannot be severed or broken(at least in common practice). It must be redirected. They understand that a flux path entering or exiting a loop must be at right angles and right angles cause the exit of flux.

Look at the methods of redirecting magnetic force connections by using a control coil penetrating the main flux path.

They also seem to understand that a well balanced system may have by-stable flux paths. Unique  :)

I am wondering what sort of power is required to run the device versus what comes out.
It's very interesting how the output power jumps with increased switch on transistion times or sharp switch transition

The rotating flux switcher is interesting. Should cogging become an issue, several phased units can operate on the same shaft to cancel the cogging effect. Solid state switching might be best, though. Here is an area that is ripe for the OU forum, has an easy to grasp principle of operation, and is well within the reach of the home experimenter. We should be jumping on this, at least to get a yay or nay on the bench.

Sounds good ION
I knew those ratiometric hall sensors would come in handy, now it's as easy as pie to measure reluctance switches.
I am getting a bit disheartened with the Rom replication anyway, just need to publish my motor drive circuit and software just in case someone else can make use and then try some of this stuff.

OK I checked the other patents referenced by both. Big red flag. Pat#6362718 is assigned to Tom Bearden and a few others.

If this worked Tom could drop out of the free energy carnival and just count his money, which would take a long time.

Still these devices are interesting, maybe there is a way to make them work. It will take a very clever individual with a novel approach.

Oh no Tom Bearden that probably means is uses lead acid batteries LOL.

Maybe worth more investigation though, how could he differentiate between small power slow switch on or high power out with fast switch on time otherwise, maybe he caught something Tom didn't.

I imagine they referenced the Bearden MEG as an example of what not to do  C.C

Tom wouldn't take the advice that reverse polarity control coils or forward polarity control coils over a gap was a waste of time, especially on a rectangular core !

As far as the rotating reluctance switch.... All that should be required is to design it so the total amount of flux never changes - or - the magnet never sees a change in the magnetic connection between the poles. That may be very difficult and would need to account for the Lenz action of the coil seeing redirected flux.



   
Group: Guest
On further reading I see they also caught the fact that an established flux path tends to remain the preferred path unless reluctance is increased over 10x.

It sounds like these guys could make a working pair of the magnetic space boots ;D

They also referred to Flynn? So I would guess they know there can only be one path (100%) at a time. I think this is where most mess up. None to date have actually made the flux path switch completely.

I wonder if these folks are still alive or suffered some kind of reputation attack.

Anyone know if they ever proved anything on a bench with public photos and data?

It was only just over a year ago the patent was granted, i did post information about them both including how to get hold of them on post 4 on this page

I woudln't stop being interested just because they reference a Bearden patent, even if it is for the MEG.

I'm still interested, but see a few conceptual problems with the idea of efficient flux switching. Maybe these can be overcome.

Perhaps these patents are just pre-emptive in case someone does develop a very efficient flux switch.

The lucky one who cracks this will indeed have something very novel.

Check out the "acknowledgements" at the end of the paper ( a 14th paper) attached to this post.

Now where have we heard of "Craddock Inc." before?

Ok. I'm done with this one.

I'll admit the descriptions are more advanced than Bearden's MEG but some things were red flags. The last red flag is the Craddock connection.

Higher strength magnets make it feasible?

Better metals for cores now make it feasible?

At least newer patents are indicating folks are trying to know more before making claims.

This one still has a better chance of resulting in something special over ideas like Bearden's MEG or Bedini's blathering.

It looks more like a fishing expedition.  >:(

I used to be very excited about patents like this, but not anymore because I learned something about the fundamental physics.    

The MEG device, Gunderson, Flynn, and other such "switched flux" devices seem to suffer from the same serious deficiency that I suspect their inventors are not even aware of.


Here's the Problem:

The permanent magnet's that are usually seen placed in these circuits, and assumed or claimed to deliver energy, do not get cycled along their B-H curves.   They just operate in the circuit at a constant MMF, and also see a constant reluctance.   This is like having a constant Voltage and a constant resistance so a constant current flows all the time,  regardless of how you direct the current here and there through various paths that all have the same resistance.   So, when I see this typical device arrangement I automatically become very cautious, because I know the magnet is not generating any excess energy per cycle.   In order for it to do so, it would need to have it's B-H curve cycled in some creative fashion, and I don't see any of these "inventors" realizing this fact and exploiting it.   All they are focused on is this idea that switching the magnet's flux is somehow like a transistor that controls lots of current with little current, and it's not a valid comparison at all, and it does not represent energy either.


I'll give you guys a very simple example how a magnet outputs more energy from the molecular realm.  We've done it hundreds of times I'm sure.  

Take a magnet and approach it to a ferromagnetic material and it will attract to it.   That's it!  The magnet has now produced free energy!  There is a force of attraction towards the ferromagnetic material and displacement in that direction, which equals positive energy delivered.    This energy can either be absorbed by your hand, as it slowly opposes the force and lets the magnet approach the material, or it could go into increasing the magnets kinetic energy and it will slam into the material creating a loud sound or shattering, etc..  but the fact is the magnet has produced excess energy, or free energy.

So what happens to the magnet as it produced this energy?   Well,  the B-field inside of it has gone from a low value to a high value, and also the ferromagnetic material is now magnetized, so all sorts of energy was created in the materials as well.  Free energy for everyone!

But there is a problem.  

Sooner or later we're going to run out of magnets and ferromagnetic materials to mate together to get a boost of free energy, and we will have to start SEPARATING some of these magnets from their ferromagnetic partners, i.e.  develop a CYCLE of sorts, and that's where we run into problems.

Magnetic fields are CONSERVATIVE, that's the problem.

This means that as I pull the magnet away from the ferromagnetic material that it had attracted to, I now have to "put back" the energy I took in the first place.   More scientifically,  no matter what path I take from a point A to a point B and than back to A, the net energy gain or loss will be zero.  In other words,  field potential is path independent.

However,  there is a ray of hope, a loop hole that can be exploited,  for example,  weaken the magnets field prior to pulling it away from the ferromagnetic material.  After all, if you bring it to zero there won't be any force on it, but later when we try to magnetize the magnet back up, we might find that we require the same energy input, but maybe not, it all depends on the material and the process used for this.  This would than be a dynamic magnetic field, but these devices here utilize the permanent magnets in a static configuration, just biasing their magnetic circuits.


Anyway,  this discussion is really to convey how these "switched flux" devices don't cycle the magnets at all, hence they can't be expected to deliver any extra energy.

I don't think it has.

This document is an application. That's all.

Yes, those are patent applications, however the three patents they reference by Flynn, Beardon et al and Pederson apparently were granted and are very similar ideas.

I have no reason to believe the patents will not be granted based on the granting of the other three patents. The patent office does not require proof of operation anymore, just a theoretical possibility even when based on a lot of "if's".

I'll stand by my statement that the idea has merit if and only if a very efficient reluctance switch can be developed. In that regard, I believe the inventors have been somewhat vague in their description of such an ideal switch, hoping someone else will invent it. In that case they will be "covered".

I say that is not the problem. Yes, magnetic force is conservative, at least in these cases (don't forget far-field EM - radio, etc.).

In fact, a conservative field should be a requirement for any flux switching device.

The real problem is all we know is energy is stored in the magnetic field and the only way to get at it is - exactly as EMDevices describes.

Do we really understand the energy stored in a permanent magnet's field? Since that field is conservative why not use it to extract energy from elsewhere?

I'll repeat myself.... The magnet must see little to no change in the force of the connection between it's poles. Discussing the intricacies of the B/H curve is not relevant. It really doesn't apply here very well anyway. What we are calling the 'B/H' curve is not just a B/H curve when it comes to a permanent magnet.

We don't want to use the energy stored in a PM field (even if there is energy there). We just wish to alternate the direction of the field flow(?). The energy<?> level should not change so none need be returned.

And... It IS very much like a triode or UJT. The transistor analogy isn't as accurate unless you equate a PM to some aspects of an SCR.

The best analogy is to a magnetic amplifier used as a bi-stable latch or two magnetic base sets for dial-indicators. These perform flux switching perfectly well with very little effort.

I think ION is right. They are doing a little CYA but don't have anything to show for their ideas. A single penetration in the flux path won't cut it anyway  ^-^

The "H" bridge configuration has a lot of merit. The magnet will not see any change in flux, so it will not be demagnetized. The external flux switch will act like a "keeper".

Creating a bistable magnetic structure for the flux switch can be an interesting design problem but is not impossible. Consider how the overcenter bistable element of a microswitch works. Now think about how that might be done magnetically and without moving parts.

I intend to try a few ideas out as time permits.
