Muller Dynamo

The amount of current generated is related to the area of the coils. Why do replicas only put coils on the perimeter.  Wouldn't coils placed in the same fashion but in rows towards the center of the disk really up the output without adding much to the input.   Why not make the disk thick and place the switching magnets elsewere and place magnets arount the rim facing perpendicular to the other magnets and then place more coils laterally perpendicular to the top and bottom coils.
Has anyone tried running the unit on a vacuum?  I bet at high velocities the drag may be using up lots of the input energy.

Keep up the good work all!

Hi Sean,

excellent work mate

Here's an LCR Meter for $17. delivered: http://cgi.ebay.com/LCR-RCL-INDUCTANCE-CAPACITANCE-RESISTANCE-METER-W-Leads-/260749773429?pt=LH_DefaultDomain_0&hash=item3cb5e5ca75

It's not worth doing without at this price.

Thanks for sharing mate

I picked up one of these meters also -- $17 bucks and free shipping!

The same company had this -- which I also picked up to get a quick way to measure RPM's of Muller and Bedini-type devices:

Thanks, Luc; may "the force" be with us all in this endeavor.

Clanzer there was a speed for the rotor that was too high and a speed for the rotor which is too slow to exhibit the same effect "supposedly" a sweet spot of sorts and without the proper voltage or current I am afraid you may not hit that spot as per romeroUK proposed. So it may just matter?

What I am yet to figure out is why some of the best replicators are already substituting parts and materials instead of building the motor to specs as relayed by RomeroUK?  I already am aware that Romero was mistaken concerning the skin effect but it just may be that the Litz wire has a hidden advantage that Romero just happened to stumble upon. 

To those doing the build verbetim; my hat is off to you guys.  Follow the build to ROMERO's specs and don't listen to the naysayers.  After all, do the naysayers have a working device?  No.  Only Romero did.

Peace to all,
chess

@lanenal / Thanks for that very useful information . It does show that those of us using ferrite rods from AM radios are working with a very different material . But note that Romero said he had used in other experiments successfully .I wonder how home made cores of Fe3O4 and resin would fit into this table ?

We probably need to strike a balance between permeability and resistance when it comes to choose the ferrite rod. And it seems to me permeability has the priority, since with the device we are not dealing with high frequencies (like 500MHz) -- the current in the driving coil is probably composed of sawtooth shapes of a frequency like 200Hz. Anyway, if your homemade core material has a good permeability (ferrite cores usually have good enough resistance), then it might work as well. I never experimented with those materials, so I don't know for sure.
