Here is the magnet shield I was referring to. It is kind of an interesting idea. Most of what he "believes" is wrong but the idea of directing the flux around one side is interesting.

Given the fact that youtube suspended his account just for showing it is also interesting.

I disagree. What is shown in that article is trivial because there's no change in energy when moving along equipotential surfaces. There's nothing unusual in that article. The reason for the excess energy is elsewhere.

Continued discussion from page 30, reply #440:

After doing some study, I have to disagree with Omnibus (sorry ) and agree with Neptune.
The V shaped track is acting as a long bar shaped magnet that is wrapped around a cylinder.
So, the horizontal movement is done by the cylinder while the lifting is representing the vertical movement, exactly what is described in the patent of Kozeka .

I did some simple FEMM simulations. The measurements in the patents match my findings, see below pictures of the results.
First picture represents the forces required to move the magnet (in this case the cylinder)
Second picture represent the energy over distance
Third picture shows the energy difference between the horizontal energy and vertical energy over distance. The total difference in energy is the last value (on the utmost right value, representing the end of each movement) in the third picture.

The essence of this is that the mechanical lift of the bar magnet should have less friction losses than the energy gained in this setup and the energy it takes to lift the magnet should also be less than the energy gain in the setup.
I am looking into lifting the bar magnet with an electromagnet.
By pulsing the electromagnet you can efficiently lift the bar magnet and re-use the energy in the electromagnet after switching off (via flyback diode)

Here's the link to Kozeka's patent once more:

@teslaalset,

I should say again, the correct understanding of this phenomenon and why we should be hopeful that a magnetic-propulsor like device (not only a V-track shaped but any magnetic-propulsor like device) is not in the mere sideways versus straight movement of magnets but lies elsewhere is the following. It is always to be expected that removing the magnets in a certain direction is closer to removing them along equipotential surface then removing them along another direction and therefore the work done in the first case will be less then in the other case. That may not, however, ensure gain when closing the loop (removing one magnet away from the other, moving the former magnet at another point of the field and letting it go back to its initial position, attached to the first magnet).

The excess energy along a closed loop is obtained only when the magnet being removed from the other magnet is also let go from the same potential surface, as I've explained here: http://www.overunity.com/index.php?topic=10177.msg270908#msg270908 .

Thus, for excess energy to be produced we not only have to utilize the fact that the form of the magnetic force versus distance may differ when the attracting magnet is approached from different points by the magnet being attracted but also the latter magnet has to be removed and let go from surfaces where it has the same potential energy. That second crucial condition is not fulfilled in Kozeka's case.

Now, having understood how the excess energy is really produced in magnet-propulsor like devices and having no doubt it is real we are faced with a major difficulty in utilizing it for the purposes of making a continuously turning self-propelled motor -- the amount of the excess energy is not only very small but it is produced in a non-technological way. In the case at hand rotational excess energy has to come from translational kinetic energy while in a case such as the shown here: http://www.youtube.com/watch?v=KnqXJbwpNRo translational excess kinetic energy obtained when the ball s moving in one direction has to be utilized for inducing translational kinetic energy of the ball in another direction. How is this difficulty to be ofercome is anyone's guess at this time.

@teslaalset . so your conclusion seems to be [correct me if I am wrong] that the energy gained by 2 magnets attracting face to face and moving together is greater than the energy needed to separate them by a sideways sliding movement . The difficulty , if this is true of using this to make a motor is as follows . As the 2 magnets attract and move together , The energy produced starts at a very low level , and increases exponentially reaching a maximum at the end of the movement . To separate the magnets , we need a large force initially , decreasing exponentially until the separation is complete . So The two "power curves" do not match .The answer might be to store the energy off attraction in a flywheel , And then ,an instant later , to use this stored energy for the separation along the appropriate path .

Here's where I'm stuck: http://www.youtube.com/watch?v=LSrgTTmHGMQ and that's not at all unusual. That's where everybody gets stuck. Now, when adding a cam you add more parameters, unneeded disbalance and weight let alone friction. A flywheel would also add more weight which has to be overcome in addition to everything else. So, these obvious suggestions don't seem to work. The goal is first to avoid gravity effects and that can be easily done. Another goal is to have only fields act and have mass as small as possible and that's not easy to accomplish. Nevertheless, the escess energy produced while making one turn still seems to be quite small to be sufficient for overcoming the barrier at the end of the turn despite the deceiving feeling one has when lifting the stator with the pencil (seen in the vid) that the work done is negligible.
