Maybe this will shock the reader:

He is using a mechanical and magnetic flux jacking in a ringing or singing mode. Look at the field / sine / dc explanation.
This is a Johnson Rotovertor with the Generator and Motor meshed on the same plane and central axis. The rotational mercury core is similar.

   When you short the coil, the field colapses down, thus a change in the mag field. Soon as you release the short, the mag pulls the field back up again. Try it on the bench for yourself.

use paint or such and always draw a schematic.
You will get more of an answer.

shorting means making a or creating continuity in a circuit,
Some use that term in that context.  Continuity in reality is a closed loop. When a meter is used for continuity,then the power source is turned off and the meters battery voltage is used. If the meter is set on continuity and the power source is on you will burn the meter up.
Electricians never use the term short for continuity. A short would be a bypass of the current to a metal box,a device,or another wire which would go to ground or the device.  Plugging in a lamp or other device you can sometimes see sparks. The original closed loop current is directed into the lamp. The lamp settles in to the original closed loop becoming part of that loop. The coil in question here has both ends of the coil wires tied together in its own loop. Power is then applied to the wires intermittently. If the current continued it would burn up the coil.

i know you like 'minimal', Mr neptune, but could you give us just a tad more to go on than this?

ta ever so  ;)

[EDIT: dayyum - i SHOULD have said "i don't see the point in this post" - but actually that's ALL i can see!]

@nul-points .You say you could not see the point ! The point is , I was basically "Bumping" the thread to keep it in the public eye . IMO There is a Gem hidden in the first 4 pages of this thread which I think people have missed .

LOL - "Bumping", eh?   

soon you'll be doing some "Grinding" on your rotor

...i'm not sure that Stefan's going to be happy about someone "Bumping & Grinding" in his forum!!  ;)


jokes aside, i looked through the thread (from the start this time), as you suggested

i agree that Romero had learnt a lot about this process through experimentation - and he was obviously quite 'fired up' about it

you can see an evolution of some ideas which re-surfaced in his Muller Dynamo rep:

 - he used the exact same drive coil circuit (apart from having a split coil)
 - he went on to add a vertical coil (on the same bobbon even?)

he fed back the o/p to the battery and found that he was able to charge the 6V battery up to 7V, at which time he would have to give it some discharge so that it didn't overcharge

he tried running from capacitor (no value given), but could only achieve a few minutes before the Hall effect circuit was affected by decrease in voltage

he made a very interesting statement, that when running from battery it was important NOT to short the Gen coils while the Drive coil was switched On - only try & charge the battery during the Off period

iirc he collected the o/p from the Gen coils into a 'holding' cap & then transferred the energy to the battery at a lower rate (& during Drive coil Off, presumably)

so - why the switch during March/April from this config to the Muller config?

he was very happy with the performance of this test - he copied some aspects to the Muller rig - and 'apparently' left out other aspects

maybe the switching required for the shorting of the Gen coils, and the slower dumping of collected o/p back to the source were just too much hassle

the Muller rep seems a much 'leaner' design

and of course - there is the secret ingredient depending on your outlook

it's either a hidden battery - or else it's something which conventional engineers would overlook!

anyway, more meat on these bones here, i think!

well 'Bumped' !   :)

lol very few people believed me when i tried to explain this coil shorting last year whats up with that =)

use a reed switch and a FWBR but have the reed triggered by a separate set of magnets (for less pulsing and drag) and end up with a MUCH higher potential to work with from a gen coil at the sacrifice of less overall current.

@Magneticist . One problem with OU research is that there is just too much info .Few people have time or inclination to closely scrutinise everything .Perhaps you could post a link to you work ?
 Edit . Does anyone know what core material Romero used in his machine pictured on page 3 of this thread . Is it ferrite?

lol its cool dude i know how it is im pretty sure its all been covered by now so thats a good thing. i had some good results feeding the pulsed gen coils back to the front end on a particular motor but it was never overunity as the battery would still eventually drain, though much slower.
if u are interested in particular a couple vids i made are

hi neptune

i believe the Gen coils are taken from a microwave oven (did someone mention fan?)  the core is the laminate on which the original coil was wound for the oven

the drive coil is basically the same as for the Muller, so probably the salvaged ferrite from a display monitor which R mentioned on muller thread

I'll copy below reply that I posted in the RomeroUK thread, since this seems to be a more appropriate thread:

A nice intro of understanding what kind of effect shortening of a coil has, is following lession from MIT on Eddy Currents, although it's a rather long video: http://www.youtube.com/watch?v=UpO6t00bPb8

If you want to skip the formula part, the central interesting part comes in from time = 40:03 where the phase lag of the current in a shortened coil is demonstrated and calculated.
In short: the phase delay of current is easily calculated by tangens phi= wL/R, where w = omega = frequency x 2 x pi.
The smaller the R, the bigger the current delay.
In theory the current delay can be max. 90 degrees.

Critical factors: R of the coil, and L, the coil value, where a low R is extremely important.
This is why litze wire is used in critical setups.
The right combination will cause the desired magnetic kick.

Understanding the above also points to the optimum timing of shortening a coil in a generator setup.
