Hey Grav

Picpick is a free photo editor and screen capture and can do resizing of pics. That one needs to be brought down to about 30% to not stretch the page. ;)

Well, like I said earlier, the foil floor is not the usual path for current to flow like a wire. There may be some push and pull for all I know. There may be possible upward push, levitation, etc.

But thinking about it more recently, the foil seems to be key.  lol, what might be interesting is if we have a panel with foil on top also. Would the mag move still? Or would that want to make the mag move in the opposite direction, negating the original effect? That may be simple to do also. Would be neat if the mag shot forward and out of the foil sandwich. ;D The top plate could be very thin plastic to mount the foil, like a larger piece of bubble pack that products are sold in, as to not have too much weight on the mag keeping it from moving. ;)

Ok. Gunna start working on the film test.  In your post showing the foil under but no electrical connection, Im not sure the foil would help being there or not. Might even slow things down due to lenz.

Mags,
   
      If you can understand what I was trying to convey with my crude sketch on the previous page.......

Foil is not necessary, this should do the exact same thing placing it on top of any flat conductor.
the motion is a function of the induction through the conductor and the wire,reacting against the magnet's field.

Sorry. I thought Grav posted that. ;D

But before we have induction due to the mag moving, the mag need to move first.

Back when I was messing around with the Whipmag, TK had little aluminum spacers mounted next to the rotor. He said he used them to regulate the speed of the rotor with magnets by way of adding drag due to lenz.  I could try it with the pendulum test.

The mag film may not be a way of seeing anything. I just did a quick test with a thin strip of foil under the film and applied up to 30v 10A taps to the foil strip. The film showed no change. Gunna try anyway. Maybe we might see some altering of the magnets field.

Ok, just finishing up here. Waiting for pva to dry. Pva is used to make molds. After waxing and buffing, waxing and buffing, again and again minimum, then you spray pva over the whole waxed surface and let dry. It helps in separation of the mold and part being formed, and puts a layer between the new resin and wax so many more than 1 part can be made with the mold before the newer resins start gripping the wax and screwing up the mold surface.

Anyway, Im using a flat piece of BUBBLE PACK  ;D backing for the top plate. I applied pva to the plastic and apply the foil. Then squeegee out the excess and wait a bit.

Then I thought about the bottom connection. Im just going to us the previous block with foil for that. Then set up the mag, hold the top foil above the mag and just let the weight of the top plate, hopefully, hold the mag in place. ;D Just incase, the mag may move on me. Either way, Im killing 2 birds here with top and bottom foil. the mag film will just be on the opposite(top) side of the bubble pack plate. I chose that for simplicity and weight. Might not get a flying mag with 1/4in plexi weighing it down. This will be easy to try things. The plastic is .2mm, but stiff enough, especially with the foil bound to it, to do an effective test, and thin enough for me to feel comfortable with the spacing between the foil and mag film.

Ok, nothing special with what we were wondering. The only effect that I got was the mag turning a bit, but only if it was off axis with the earths poles. I did a YT vid of disc magnets set up on edge on the table and they spin to align with the earths polls with surprisingly strong force. So if the mags I have are just a bit off of earth N n S, there isnt enough pull on it to be in alignment while sitting on the foil. So when I turn up the current, the mage rotated CCW just a bit. The only way to get the mag to sit way off alignment, it has to be reverse and balanced into position. So far, the mag rotated just about as many times, CW and CCW.  And only when current was turned on. There were a few times the mag rotated from disturbing it while setting the top plate down. But if it stayed in place after setting down, adding current, around a few amps at 5v, depending on the mag, the mag tends to want to align with earth N n S more so than by the mags own strength itself.

Will see what I can think of next.  If you have disk mags, foil and a battery you can play.  Ace hardware generally carry 1/8 x 3/4 neo discs. And 1/8 x 3/8.

Put 2 together to make them wider.

Oh. There were a few times where I thought I saw some little changes tight on top of the mag in the film. But ut was the foil burning. lol Just tiny holes. Also, sometimes the mag would stick to the top plate when lifting. When looking at the foil surface, I didnt see burning, like welding to the magnet. So a couple more times and I was a little convinced that the foil was becoming magnetic. Lol. But when I removed the film from the top, I could see the burn holes more clearly.  Ive had so many moments like that where I think Im seeing some crazy stuff, and it soon become it is me that is crazy.  ;D Then Im brought back to reality.. ;)

Thinking.

Probably the top plate with currents flowing in the opposite direction relative to the magnet is producing an opposite push/pull on the magnet as compared to the bottom plate, so no roll.

So to get the current from top and bottom plates to flow to or from the mag, then say make both plates + and apply the - lead to the sides of the mag, possibly in the middle of each pole face, or, on the front and rear of the mag as it rolls.

Didnt see any field changes in the film. Ill retry using a magnifying glass to take a closer look.

Was odd that it helped the mag to align to earth poles. Possibly the mag is pushing up off the bottom plate and pushing the upper plate up. Just some, to reduce friction so the mag is free to spin easier than without the current.  Its the only thing I can come up with. Will try all these things more tomorrow to be very sure on what ive seen so far. Wanted to do a vid. But not much to put up a vid about. The mag being able to align to earths poles easier doesnt need any more explanation.

At first when it did turn, i was kinda hoping for a full possibly continuous spin. But when I work it out in my head, there shouldnt be any spin in this config. So Im left with the possibility of levitation and friction reduction for a reason that the mag reacts as such when current is applied to the magnet.

lol. Could do the original config and put a wall in front of the mag, then dump a cap into the mag and see if it jumps being it cant go forward? Such a simple set of ingredients and finding many 'odd' things that apparently have not been done before. ??? ;D

Just thinking here right now, I wonder if I set the mag on the foil like before, then apply current to the foil from one side to the other, front and back, or side to side and see if the mag moves/rotates.

Never ending things to try and learn more from.

Looking to try a small test unit based on the AC experiment shown in that Knoxx-lindeman video shown earlier in thread, that destini paradox experiment is very similar and tends to invalidate the " edge " of the magnet theory from the IEEE paper and validates the ac experiment from what i can tell.  Looking at 12 inch dia x .125" thick aluminum disc with n42 block magnets, will copper plate the Al and try to validate the brush pickup locations at the center shaft as mentioned in the video.  Center brush locations would make this much more easy to build and connect in series many machines, AC output should be able to run through a transfo, run a 4 magnet AC disc at 1800rpm should give 60hz.  Very interested to see if and how any back torque shows on input drive motor power.
More to come soon.....

Ok, so I built something similar to what was shown in the lindmann video as the AC homopolar generator....  Only running a little over 500rpm but its 12' diameter .125" thick aluminum disc with 4 of those n42 magnets 2" long, .5" wide and .25" thick on each side of disc.  Put a 100A ct with a large copper wire through the middle to serve as the brushes for detecting current with scope and 51 ohm ct load resistor.  Seeing a few amps through ct with scope at outside 90deg apart locations and also at 90deg on center shaft.  The catch is it also shows the same current(or even greater) if i touch the two ends of the wire together near the brush locations to form a loop!  Looks like most of the induced current is from stray fields from the magnets so I put 4 steel bars on the magnets to close the flux through the disc through the adjacent magnets that are opposite pole direction to reduce the stray flux cutting across the "brush" circuit.  Unfortunately the .25 inch thick plates/bars do not contain all of the flux so I still get induced current with brushes shorted near center of disc, but induced current with brushes at 90deg on rim shows almost no induced current now that most of the stray flux is gone near the rim.  Will take some more precise voltage measurements with scope and post results with some pics when I have a chance for those that are interested.
Cheers;

I'm going to build a mini-metal foundry to melt aluminum cans to cast customized aluminum logarithmic spiral discs.  The logarithmic spiral is the shortest spiral with the maximum electromagnetic torque.  A spiral conductor is a unipolar machine, whose rotation direction doesn't depend on the current direction.  When the current direction in the conducting spiral is changed, this implies changing simultaneously the current and the field direction.  The spiral disc is a universal machine, where it can run on both AC or DC.  No external permanent magnets will be used in this configuration.

I'll be stacking the spiral discs to form a large single cylinder disc.  The two outer most discs will have the spirals going in the same direction and will use either a centrifugal current (axis to rim) or a centripetal current (rim to axis).  The inner discs will have half of the disc with cw spirals, and the other half using ccw spirals.  The inner and outer discs will be connected in series.  The inner discs will be using a diametrical current (rim to rim), thus the reason for using both a cw spiral and a ccw spiral.  The external electrical contacts will be made at the axis of each outer disc in a conductive liquid using two sphere's that rotate in the conductive liquid.

Hi gravityblock


Great idea!
Everything is floating inside aetheric boiling waters with energy bubbles coming out of singularity,
creating electromagnetic pressure differentials, waves, vortices, streaming flows with all kinds of interactions between them.
It is logical to construct a complex 3D geometry to guide random eather streams of energy along paths of least resistance or
the opposite, ways we can build a virtual clockwork that can harness energy fluctuations from the eatheric environment.

Sacred geometry, genuine designs from crop circles...

I wonder how would a fractal 3D shape behave as an antenna on top of a Tesla coil?

Do you remember Arecibo reply glyph?

And here is a crop circle rconstruction site of Zef Damen - great for inspiration on the geometry!

The logarithmic spiral is the shortest spiral with the maximum electromagnetic torque. 

OK, then, GB, that's what I had in mind when I picked up a roll of bare #8 copper wire to form the spiral arms.  I figured that by starting with a 2" copper pipe cap, I could then radially array as many of the individual bent pieces of wire as would fit, even tapering the center ends to pack as many as possible into the plane.   By spacing the outer tips exactly, I would set a perimeter band of Cu to pick power off with a brush.

As far as laying out the radials so they create the opposite rotation, might the pair of disks benefit from an additional magnet disk between the two, joined at the outer rim, and picking power from the center caps?

Current flow:

F   ^ <field>  v  F
I   ^      "      v  I
E   ^     "       v  E
L   ^      "      v  L
D   ^      "      v  D

Still haven't made any progress in the last year, but all the parts remain on the bench

Yes, but you will need two magnets in opposition if you plan on picking power from the center caps ( --N/S--S/N ), or one magnet if you plan on picking power from the center and the rim (assuming of course I understand your question correctly).  The spiral discs I plan on creating will be somewhere between 6" - 12" in diameter.  A 6" - 12" diameter magnet will be too expensive to incorporate into my design, so this is why I'll be stacking the spiral discs in series to form a large cylinder without the use of any external magnets.  It takes approximately 867 aluminum cans to produce 10 lbs. of aluminum.  So, the thickness, diameter, number of cans, and the number of spirals on each disc will determine the overall diameter and length of the cylinder.

Yes, it will take three magnet disks with polarity properly aligned.  The center one must float, staying aligned with the outer two.  I thought of a significant pair of neos, one on the center's perimeter, and the other outside the Cu band, held stationary.  Not simple, but it allows stacking disks and economy of fields.

One-piece magnets are out of the question (not enuf turtlebuks) so I have a stack of 1x4x1/2" neos to array. I would think that since the Cu disks really are a collection of "strings", that a solid magnet would not be as important.

I also think the greatest power will be picked in close proximity to the magnet fields.

I ain't built it yet

Built some more test device configurations this time with 1.25" copper pipe in a drum type configuration to more easily test out some different ideas.  I put steel in center for shaft with 6 of those n35 magnets 2"x.5"x.125" all with n pole facing out wards through surface of cu tube.  Placed a piece of steel pipe 1.25" diameter x 2" long that fit perfectly over copper over the center of the copper tube directly over magnets to concentrate flux through copper tube.  Spun it all at 1400rpm and get 14mv dc with brush locations as close to center on either side of steel pipe as possible.  Put a 10 ohm resistor across contacts to ensure it wasn't brush noise but is definitely unipolar induction not noise. 
Then I tried same setup but with 3 of the magnets north facing out through the copper and on other side 3 with s pole facing out to test the AC homopolar gen idea which seemed like great potential for number of reasons.  I spun it at 1400rpm and got AC as expected! 
Here is where it gets interesting.....
I found that there was a great deal of magnetic flux all around this thing that was inducing current in external cct and could be generating false output so I wrapped the center of the thing over the steel pipe with a few pounds of paddle wire to contain all the flux in center as it was saturating the steel over jacket in center previously.  When I spun it I ago no measurable AC output.  This is consistent with what I saw when trying to close the flux thru disc previously in disc style AC test. 
I have one more test to do with closed flux in dc config to confirm but it is looking like this only may work if The brush cct cuts the return flux from magnet.  Interesting because that portion of cct is what would experience the back torque due to Lorenz force.  More to come!
