Dual Piston Device with Permanent Magnets

have you thought about laying this horizontally to nullify gravitational effects.....just a thought.

Yes, from the beginning it was supposed to be horizontal. But since I used this type of gliders under the magnets, the magnets were 'hanging' on the cariages and the presure of the lever was against the rail. OR: the magnets were standing on the glider and the lever was pushing the cariage to the side of the wheel. Both situation gave lots of extra friction. I needed the weight of the magnets AND the pressure of the levers into the same direction: pressing onto the rail and therefor the direction of gravitation. That is why the model is almost vertical now.

An update:
I tried my first shield and I discovered two things:

1. My shield was mounted too low. It went down too much and the magnets repelled where the should attract. Result: wrong direction of the fly wheel.
2. I need to find a better way to keep the shiled straight between the magnets. Now I have 2 parallel glider but tuning them 100% parallel is very time consuming. And this tuning has to be done every time I change shield.

Conclusion so far:
a.Attaction and repelling forces are very strong but easy to control with the linear bearings.
b.The current way the shield is mounted gives too much friction but the new shield holder will save this.

ToDo:
a.Building a new shield holder
b.Mounting the shield higher
c.Making the shield thicker. Repelling forces are passing a shield that is too thin.

Hello, (I'm new here)
I've been trying to do something similar 2 years ago, but I dismissed when I realized that the magnetic field was passing through the iron (nearly?) without any loss of power.
But then reading this topics I got an idea base on the statement that it's maybe possible to find the balance between attraction (to iron) and repulsion of the magnet(N<-->N). But this balance is not only depending to the exact moment where the shield is removed, but also to :
- the distance between the iron plate <--> magnet
- and the distance between the magnet when the iron is in the middle!

So, actualy, I think that the iron plate has to be removed from the path of the magnet at the exact moment where the attraction repulsion is balanced. Not when the magnet is very close to the metal... because the power is proportional to the ^3 of the distance. So if the magnet get to close to the metal, there is no way that the repulsion between the magnet manage to compensate...
Plus, I would use 2 large magnet (not only powerfull ones) because the distance the force is affecting is proportional...

Let me know if it help!

Something else, when the shield try to go up, the two magnet are pulling it... so why don't fix two other magnet over the shield, like in this pic? The idea is that these two fixed magnet could annulate the strength needed to take the shield out of the (piston) magnet path...

  ???I have an idea that may connects Steorn device with dual piston device.
At Steorn Low Energy Magnet Actuator device , if in front of each magnet at outside of shield, we put another magnet in repulsion mode, when the  shield moved, the magnet that will be  pushed because then shield is removed and magnetic field appear. Thus we obtain a lot of energy with the low actuator
