Gray Tube Replication

Thanks! It's going to be a whole lot spiffier before its done... I've been
thinking about what kind of energy would be picked up on a secondary
of the same guage wire when having it wound bifilar as a ratio of the amount
going in to the primary. One-to-one seems a bit optimistic, although wouldn't
it stand to reason being somewhere near this value?

With the flux of the magnets providing energy in addition to the primary
windings, I'm thinking this could easily take off with the added bonus of
mechanical output and a parallel electrode array just for the purpose of
punching some batteries with a second LV cap bank and string of diodes.

Currently I've disassembled the motor and will be adding layers of the 25g
wire from the video. The arms holding the bearings are a bit close to touching
the sides of the motor tube so in order to fit the whole spool on there it
will likely need to have a wider base fitted. At this point I'm not sure that
winding the entire 2000ft spool on the outside would be practical due to the
falloff of magnetic flux from the 30g primary.

I'll see about getting the audio in future clips, it would really add to
getting a feel for how much force is being generated. I'd like to reinforce
that while the concrete cinderblock may look like overkill it is almost not
enough weight. When running it will eventually thump its way along the floor
due to the intense vibration.

The electrode box is nearly airtight except for the circular holes where
clearance has been left for adjusting the copper rods.

Geotron, that looks great!

Any chance to get a video with sound?

Also, how sealed is that box you have the gap in?

video error

Video doesn't work. It is only 8.something kb.

developments

Whereupon completing a number of experiments I've found that while the
battery feeding the inverter will accept the output directly from the
pickup rod onto its (+) pole with the (-) side connected to return it
to the Cathode of the LV-side capacitors without throwing an error on
the inverter, it is not possible to do so by first sending the Output
into charging the motor coil.

This being the case I have put together the only other option for a
quick demonstration. On top of my motor there is a 2000ft spool of 25g
hooked to charge up a bank of three 450V 10uF capacitors in series.
They are in the standard fullwave bridge arrangement.

In order to further expand the recovery system I'll be rewinding the
current motor coil as bifilar and adding the second half also as a bifilar
winding. In addition to this, the ignitor will be triggered by a reed
switch, and once the driveshaft is straightened will be utilized to provide
mechanical work output for spinning an alternator of some kind.

With the construction of a second electrode array or tube, it will mean
perhaps even more recovery with a second burst being generated only to go
back to the battery without first being picked up by a coil.

I'm not sure what has happened to the yTube video service, but it
will not allow me to upload citing an 'Unknown Error', thus I have made
the demonstration available as a download-only file.

autotransformer

WHY ignition coils? They have that annoying internal bind between Primary and Secondary! What about those HV transformers out of copy machines or strobes? They have an unbound secondary.

You are defining an autotransformer - it is not an issue. Feel free to post
your replication attempts with another transformer, there are many possible
ways to do it. Would like to see it.

only the recent diagram edits

You've shown this inverter connection in a couple of diagrams already, but I'm
currently unaware whether this will in fact send energy back to the battery.

The most recent diagram I posted superceeds everything else.

I may not have interpreted your diagrams correctly each time
but your last diagram that I made edits to was the clearest and most
accurate to date.

3 grounds - that is it

Yes, I will indeed be grounding the ignition coil from this point on, thank
you Aaron. Would it also be prudent to have the inverter (-)AC input pole
connected? I'm thinking that it would be somewhere on the way to the (-) battery
post and would supply it with a portion of what isn't absorbed into Ground.

The only grounds that need to be connected are the 3 blue dots I showed.
If you do it that way, you will get results.

solution to ground

Ok, as it turns out, my problem with the inverter was due to a faulty
ground connection. After properly reconnecting it there are no more
voltage warnings.

Even with the Output rod connected directly to the (+) Battery on the
inverter and the LV caps charging onto the (-) pole it still keeps running.

I'm guessing this is probably not the best idea to keep the battery
charged up in a longterm sense, so I'll be adding a recovery-cap system.

In regards to collecting the bEMF from my single coil of 30g, the following
parallel connection is what I had in mind. It seems as though it may reduce
the amount of magnetic force generated around the coil ... ?

configuring for recovery

You've shown this inverter connection in a couple of diagrams already, but I'm
currently unaware whether this will in fact send energy back to the battery.

If not then I must configure it to be a dual-battery system with either
a Run/Charge automatic swapper, or otherwise find a different way to accomplish
the recovery of what is produced in a useable form.

At this point I've found that in any configuration with the Output connected
to a battery also in contact with the inverter supply cables will produce a
voltage warning and temporarily disable the system. Then again I've not yet
had a go at it with the ignition coil (-) primary connected to ground. I would
hope that doing so would supress whatever is causing these malfunctions.

@Geotron

Geotron,

This is all you have to do...

1. Leave B2 out of the picture.

2. Tie all three grounds with the blue circle together exactly
as I show.

If the MOT's cap is charged and you trigger the cap into the
primary of the ignition coil, you will get that coil to pulse. If
you do it exactly like that, you got it. When you confirm that,
just put a wheel with magnets over the coil and use a hall effect
sensor as a pickup from the magnets to trigger that SCR and
make it adjustable. Just make 110% sure the magnets on the
rotor will not break off in any way, shape or form or you'll
regret it. I had three 1/2" neos that are 1/2" thick in the rotor
I used. Rotor was machined to be press fit then I used as much
superglue as I could. If I get back to that particular setup, I'll
wrap a couple layers of packing tape around that whole thing
just in case - no joke.

By the way, the ground at the ignition coil, you want it right there
at the ground terminal so the HV will get right to it. You don't want
the ground after the scr.

Geotron, the link you posted won't go directly to it.

You see the "Permalink" link at the top right, I don't know why but that
never goes to the post.

If you use the actual #XXXX link, that will go directly to the post.

There are a few tweaks needed to your diagram in the latest post, but you're
99% there.
