I'm not 100% satisfied because the coil are made with litz wire and maybe there is
Some broke wire or i don't cleanup properly the ends , wanna redo the test with magnet wire stay tuned

Ciao Luca

Conradelektro is resuming testing of Tesla's pancake coil. I'm resurrecting this thread and transferring comments from the "Self accelerating Reed switch magnet spinner" thread where they originated.


Here's the latest comment from Milehigh:

Conrad:

For the pancake coils, about 10 cm in diameter should be fine.  You can use whatever gauge of wire you want for the pancake coils.  I would recommend that you do a regular and a bifilar coil and use the same wire.  You may want to use a smaller gauge of wire within reason so that you can get more inter-coil capacitance with the bifilar version.  For me that's not really a valid issue because my assumption is that the inter-coil capacitance will be insignificant and will not show any significant effects.  The effects of the capacitance will be so small that in many cases they will not even be measurable.

There is a fair amount of magnetic field self-cancellation in a pancake coil so I would expect that the inductance measurement would be quite low.

This is a typical case were visualization in your mind can be used as a tool.  It's easy to visualize the field of the spinning rotor magnet.  It's easy to imagine how each individual loop of the pancake coil will "see" the changing magnetic flux.  Where it gets complicated in this case is what happens when current starts to flow in the pancake coil and how do you visualize that?   A loop in the middle of the pancake has a relationship with both the smaller loops and the larger loops.  In certain regions there is magnetic field cancellation and in other regions there is magnetic field addition.  The net result is that the pancake coil has a certain inductance value and a certain field pattern.  Thankfully with the scope you can just look at the resultant waveforms and put the complicated pancake coil geometry inside a "black box."

Whatever tests you do with your regular and pancake coils, it's great that you are willing to do comparative tests.  It's really important and it would be good if all experimenters took this approach.  Will you find any differences between a regular pancake coil and a bifilar true-Tesla pancake coil?  I am assuming that you will not see any differences.

This guy is so good.  This is about being trapped in the bubble.

Who's in the bubble and who's standing outside?

I don't have much time for magicians they are liars.

The guy used a trick deck of cards, the Ace of spades is black but the rest of the cards are the wrong color, the clubs are red and the diamonds are black ect.

The best way to deal with magicians is to realize that every thing they do is an illusion and they spend a lot of time and effort to trick people which is pathetic.

I bet if I put in enough time I could trick him in several ways. But to what end, should we really be admiring deceptive people. If he had used a standard set of cards it would not work so well. I'm not impressed at all. Kiddies tricks.

Cheers

P.S. He's an amateur, he needs special props and camera tricks. Busted almost immediately I watched it.  People think of say the 7 of diamonds and they will look for a red card and disregard the black cards which is the smart thing to do as it takes out 50% of the cards to look at, Simply put if you think of a red card you do not look at the black cards. It would not work with a standard deck of cards. meaning it not much of a trick.

Look at it this way I visualized a red 7 of diamonds and that card never existed in the deck, it was never in there so he did not make it disappear, therefore he is flat out lying.

Without the lies there is no trick. The illusion is invalid as it is based on a deliberate lie. If the Ace of spades he shows was red like the other spades, the gig is up before it begins.

So MileHigh, would you say I am trapped in a bubble ?

second picture shows the "Black 7 of diamonds" which is not the card I visualized, he never made the card I visualized disapear because you cannot make something not there disapear.

I am going to quote Mark E. from a PESN comment on the subject of Dollard:

You can't just look at a setup and say, "That's longitudinal energy in action."  You would have to prove it and that means you need a fancy lab set up with all sorts of RF measuring instruments and you would have to know what you are doing.  Light bulbs under water is a parlor trick I have seen many times.  Water is an insulator and the electricity will take the path of least resistance which is through the light bulb element.  It's like a magic show taking advantage of the audience's preconceptions and using a bit of misdirection.  Can you see clearly?  Have a look:

If you can point me to an experiment that shows something special, I'll have a look.

MileHigh

The first trick is explained in the video it is camera angles.

The second trick is likely using trick glasses and/or trick fluid that foams up and increases volume. He begins pouring the liquid in the very side of the trick glass and when nearly "seemingly full" he tips some towards the middle, he never shows the inside of the glass from the top and the trick will no work if anyone asks to see inside the glasses. We can see the fluid becomes more translucent in the bigger glass when it should become more opaque due to the light being less able to penetrate through more liquid, which tells me the liquid is only around the side of the glass in a cylinder and not filling the glass. If he spoke he would be lying. There is nothing admirable about deliberate lying and deception.

..

There is only one type of energy and it results in work done, If work is done it can be measured, those who say the work done by any so called longitudinal energy cannot be seen to be done and measured are mistaken I think or mad. (not saying it cannot be called that just saying), energy is energy. Gee wizz.

Any argument that work can be done and it cannot be observed is non sense. 

..

They continue to maintain there is something special about apparent propagation velocities, but the effect is predicted and calculated by the online Tesla coil designing apps, so the effect is already well known and understood. And there is ample proof of that.

Farmhand:

I think that you are taking the wrong message from those clips.  The clips are about showing you how your conceptions, preconceptions, expectations, and basic human limits in on-the-spot mental gymnastics can affect you and how you percieve the world around you.  You can apply that model to what can transpire when a fake free energy clip is seen for the first time by an enthusiast.   It's akin to an optical illusion but it's a psychological illusion.
