Hi Floor,
  I assume that the 'EPM's are the part of the setup which you think may provide OU? Are you working on the basis that they will provide more magnetic force than a similar coil with a steel core for the same input power? If so - then you could just test one of those...

However, I think it's likely it'd give you much less magnetic force than a standard coil - because the PM core will not contribute as much field as a steel core would. Also, if the steel casing isn't magnetised by the PM when the coil is off - then surely that means it's won't be contributing anything when the coil is on either. So the overall effect would be as if the coil had no core at all. Also - as the metal casing goes all the way round - it shorts out the magnetic circuit - so there would be very little field outside the casing.

Imagine two solenoid coils, one stationary and the other current reversing on a treadle. The treadle has a charging magnet piston attached to one end to supply output through a pickup coil. The unit should run close to unity with an equal charge to both coils. 


Replacing the stationary coil with a PM of equal strength should deliver the same output. Doubling the strength of the stationary magnet stator should yield a COP of >1 right?

Hi Synchro. Not sure what you mean about a 'treadle', google images thinks thats part of a sewing machine...?
Or a 'charging magnet'...? Maybe a diagram?

However, in any standard type of generator, it's Faraday's / Lenz's law that limits the system to COP<1, not the strength of the magnets. To make a generator OU, I think you have to change the geometry so the back-emf has somewehere else to go - other than just straight back at the rotor. But you also have to make sure it has something to react against - else there will be no real power in the output - like the 'toroidal generator'.

Maybe it would be possible to design a generator where the coils' back-emf react against each other - rather than the rotor...

@Paul-R

Yes I think you are correct, at least for most types of magnets. Neo mags would hold up better, probably ?
