Gray Tube Replication

vacuum and other side

I think when the HV hits and bounces off the blocking diode it creates a vacuume or maybe a venturi effect on the cap and pulls out the available current. Has anyone thought about trying to capture the output voltage/current on the other side of the spark gap instead of running it straight to ground

You're right on vacuum to pull power from the cap...the potential...the current is through the other part of the circuit pulled out from this as well but from the backside.

I have already captured the output on the other side of the gap and it makes almost no difference...as long as you are in series with the event, you get it.

great vid!

WTF,

Great test! You'll see that just like you have it setup if the cap and everything is scaled up, you can run a motor on that choke.

[martin]

Well, while Im still thinking, let me say this... If the 'radiant' event that supposedly takes place in the tube or motor was happening back during all the demonstrations, doesnt anyone think that it would have been mentioned about a stinging effect taking place? According to Tesla, it's an effect that's pretty hard to ignore?

Hi Everybody,



@Aaron,

Could you give me an idea of what a good cap value would be to design a motor around for this type of circuit that you're referring to.I'm trying to piece together a motor concept based on my own thoughts of what I think may be a good idea hence the reason that I believe that the rotor section should cover 112.5 degrees on each side of the rotor and have the stator cores located every 90 degrees so that in a future modification that i intend to make on the rotor will add a coil to the center strip of metal that you can see in the video this way I can play around with a setup that will allow a push pull type of affect,but that will be for a later modification.I like this setup because it allows for some modification to the rotor for different ideas that can be reasonably easy to incorporate them.I think that I grasp the idea of the circuit from previous and crude experiments that I setup to see the affect of the water sparkplug circuit and I believe that I was one of the first people to mention that it looked similar to the Gray circuit (and wanted to see someone apply it in an electric motor).I am really quite the novice for anything beyond the SSG circuit,Electronics wise as compared to most people in this forum but having said that I believe that I may be able to have something to contribute to the geometry of a motor setup... only time will tell.Sorry for drifting off topic a bit to anyone offended.Thx for any guidance

Stinging effect cease above 10 khz so even at 6khz it would be negligible.

Stinging effect cease above 10 khz so even at 6khz it would be negligible.

6Khz was just the power supply switching frequency. The spark/radiant frequency was in the hunderds of Hertz. So I think Martin's question is still valid.

stinging effect

Well, while Im still thinking, let me say this... If the 'radiant' event that supposedly takes place in the tube or motor was happening back during all the demonstrations, doesnt anyone think that it would have been mentioned about a stinging effect taking place? According to Tesla, it's an effect that's pretty hard to ignore?

Where are all the stories from Gray, Hackenberger and all other witnesses reporting being stung from being around the motor or tube?

[martin]

Aaron, Exactly! I havnt heard of any. Even Cole's original supply was supposed to have run around 100hz.

[Electrotek]

The presence of, or lack of, a stinging sensation could reveal the effect the Tube is producing. In order to have a sensation, there can't be an arc to the grids, presuming the rest of the geometry matches Tesla's setup. Some of us think there is such an arc. However, freeukpower did report the sensation with one of his tests. It's possible the Tube can be used in more than one way.

cap

@Aaron,
Could you give me an idea of what a good cap value would be to design a motor around for this type of circuit that you're referring to.

It depends on how fast the cap can charge from the power supply and I personally want everything powered from one battery or bank.

But with this circuit concept, I've used 1000v/around 20uf down to 200v/330uf...I used smaller caps but really is too small. The LV side caps I used to pop the 2 coils apart were 400v/330uf.

It is difficult to get any of these caps to jump a gap but it easily happens if used as the LV side or analogous to cap 38. It doesn't matter which side the cap is or where the coil is located in series with the discharge event...the coil will charge with the impulse. It can be with two caps or 1.

It my opinion, the Gray setup is the way it is to simply upscale everything big for the purposes of driving a motor that can drive a car. If you see an early prototype...it is a small toy model that fits in his hand.

Anyway if there is a big cap in front and in back, then you jack up the effect but the effect happens in any order with any variation that simply has the discharge with an inductor in series.

If I was doing a roller skate wheel rotor sized motor for example, I'd start with a photo flash cap from a disposable camera and go up from there with a coil around 600 turns with a core 3/8" diameter and magnets the exact same size as the core..if you're repelling a magnet.

Ideally, the cap and coil should be tuned...some other members can probably show how to calculate this.

The ignition coil will charge a peaking capacitor on 1 single pulse just like Tesla's method of conversion and that increases energy transfer from coil to gap on a normal ignition system from 1~10% up to 50% or more. With non-resistor plugs, transfer can be up to 80+% efficient.

So, just a normal ignition coil just sparking to a resistor plug is as low as 1% efficient and up to 10%.

The peaking capacitor stores some of the output from the coil and adds to the spark after the cap is charged on that one pulse.

Repulsion Coil Test

I did my first test with my pendulum MOT coils. The first attachment shows the swing with the Switch Tube outside the inductor. The second picture shows the slightly greater force when the Tube is inside the inductor. In the third picture, the black line in the end of the Tube is a chunk of mouse pad used to support the electrode.

Here's a video:

I'm using the hot stick wire on the left as the commutator, to the diode.

6Khz was just the power supply switching frequency. The spark/radiant frequency was in the hunderds of Hertz. So I think Martin's question is still valid.

It CAN'T be at hundred of Hertz, maybe you thought about hundred of thousands of Hertz ?

[What The Flux]

No, I mean the frequency of the firings of the CSET. The max RPM of his motors was 5000 RPM or 83 RPS. In his simplest version (the one with three stators) I believe the CSET fired 3 times per revolution.... or 250 Hz.
I don't think we're all talking about the same thing here.

If CSET firing would create stinging effect then it would be reported.
I ASSURE you that as 250Hz radiant energy is painful and scare shield effect around transmitter.
CSET surely produce much higher frequency oscillation.

[Jetijs]

Aaron already said, that frequency has nothing to do with the pain effect, all that counts is the pulse length. If the pulse is short enough, it wont cause any pain effect even at 1Hz.
