Hi baroutologus, thanks for that.
Don Smith has had several strokes and is now partially paralised.
I don't think he will be replying to any emails.
His Son has no technical nous, so it looks like we are on our own.
I attempted to duplicate Dons L1 and L2 coils as closely as possible with the former diameters and number of turns. i.e. 5 turns L1, 17 turns L2.
However the most importanat point that Patrick Kelly / Don makes is that L1 wire length must be EXACTLY one quarter of L2 wire length.
This I did.
You suggest a probable frequency of 200 kcs?
Did I get that correctly?
But the output of the neon transformer is 35 kcs that Patrick / Don says must be taken all the way through.
i.e. L1 res. freq. 35kcs.
L2 res. freq. 35kcs.
35 kcs doesn't divide into 200 kcs.
How would this work?
I am getting a very tiny voltage out of L2.
Input to L1/cap. is 3kv as Patrick/Don suggests, but as mentioned before, L1/cap. impedence at 35 kcs is only 2.5 ohms so the 3kv is basically shorted out.
Neon transformer to two diodes to L1 and cap..
No spark gap is shown in series with this in Patrick/Dons circuit.
Neon transformer can deliver 10 milliamps max.
This is a terrible mismatch of impedences which I find hard to reconcile.
The only spark gaps shown in the circuit go to ground and are supposedly for protection from over-voltage.
I certainly havn't had to worry about over-voltage! It gets nearly shorted out!

[baroutologos]

I do not suggest anything. Just Don Smith's setups do not make any sense.

From calculations, as already said, it's estimated that the particular device runs at 200Khz. Yet the mechanism for oscillation seems inefficient. Yet at 200 Khz, the wire lengths seem totally irrelevant.

λ/4 of 200 Khz is 375m more or less. Those L1 and L2 are hardly 5m. So no use in talking in wavelength terms.

As you say, we are on our own..

Stebra:

The thing you're not understanding is the purpose of
the spark gap. When the sparks are jumping across, it not only disturbs the ambient atmosphere
but it also creates thousands of much newer and HIGHER frequencies. So the resonant frequency you use isn't all that important as long as it's the same one for both L1 & L2. These circuits will just pick the proper freq. from the thousands generated. The 35kc is irrelevant.
On page 3-39 is Patrick Kelly's version "As I understand it". So there may be errors. The NTD is driving the L1 coil as a parallel resonant circuit which can't work because the coil is shorting out the S.G. The other thing is, for max transfer of energy, you should use a series resonant circuit,which will also enable the S.G.
My setup uses a 2.5 " B&W coil for L2 with 18T of heavy extension cord wire for L1. L1 being in series with a 125 pf cap. Resonant freq. is 5.5mhz.
I'm getting thousands of volts across L2 as I can light up an 18 watt CFB by just holding it close to L2.
Hope this helps you somewhat.

Hi Elcheapo,
thanks for that.
Your thousands of volts generated on L2 certainly looks promising!
Have I got this right now?
Eliminate the two diodes on the output of the neon transformer.
Neon output now (one leg) in series with spark gap, then in series with the 125 pic. cap, then in series with L1.
Other leg of L1 to neon transformer?
You have given 18 turns for L1.
How many turns for L2?
How did you decide on an appropriate res. freq.?
Do you also follow the stated requirement of using one quarter the wire length on L1 as is on L2?
Is this quarter wavelength requirement of L1 neccessary?

Even at 5.5 Mcs., the wire length for quarter wave is around 44 ft.
Have I got this correct?
Thanks, in anticipation.
18 turns on your former I think is a lot less than this.

Stebra:
No, you leave the diodes & S.G. in as per the circuit.
The only thing you should change is to put c1 & L1 in series & connect across the S.G.
I don't think the wire lengths are that critical. wavelength is used just to get you in the ball-park.
Of course voltage build-up is greatly affected by the L2/L1 turns ratio. On this last setup the length of L1 was 10.5 ft. L2 is 50ft.(75turns) I just had L1 wrapped around the center of L2.
On my previous setup, I used a 25ft pancake coil for L1 & had L2 sitting in the center of it. Got about the same results as this last one.
I don't choose any "appropiate frequency". I let the components I have on hand ,do that.
I am using a pulse-width generator driving a tv flyback xformer & a home-made c1 hv cap (125pf).
Getting both circuits resonant at the same frequency is the tricky part. I use a scope & generator to check resonance. I use a variable cap on L2 to match up with L1.

Hi Elcheapo,
thanks for your very informative help.
I am now feeding from neon transformer 3kv throuh fullwave bridge (unsmoothed) into spark gap, then to L1 and paralleled cap on L1.
Other leg of L1 back to neg. of bridge.
Is this correct?
So pulsed DC is fed finally to L1 and its cap.
I am now getting enough output from L2 to light up an 8 watt fluo tube directly connected, to about one quarter of full brilliance.
I have yet to tune L2.
L2 coil only used at this stage - no tuning cap.
The whole point of this circuit is to entrain environmental energy into L2 right?
with substantially more output than input.
What is your input to output wattage ratio?
This is the whole crux of the matter.

[Elcheapo]

Hi Stebra,
You said"I am now feeding from neon transformer 3kv throuh fullwave bridge (unsmoothed) into spark gap, then to L1 and paralleled cap on L1.
Other leg of L1 back to neg. of bridge."

Not sure what you mean by "L1 & paralleled cap". The cap & L1 should be in series. But if you're seeing sparks across the gap then you must have it right.
Glad you got some voltage on L2.
As all this stuff is quite new to us, I would say to continue to follow Don's wire length formula just in case it might help things.
My take on this whole thing is: We need a highly efficient Tesla coil circuit and get it to work in reverse.
I've been studying an article on construction of such a circuit that pulses an 8kv 60cps sine wave across a S.G. and this thing throws off 30 inch sparks (over 1million volts).The primary is 8 turns of copper tubing in series with a .02mfd. cap.
My understanding is much like yours.
The L1 circuit creates the ambient disturbance and the HV L2 circuit attracts this free energy back into the circuit.
So I think the higher the voltage we can get across L2, the greater the attraction.
We need fewer turns on L1 and many more on L2
to accomplish this, at whatever frequency we find convenient.
As for my out to in power, I don't have the means for measuring the high rf voltage. My scope only goes to 800v. When I find a way I'll let you know or
maybe you can tell me!

Hi Elcheapo,
I have just tried the cap in series with L1 insted of in parallel, but no matter how close the spark gap is reduced to, no spark.
My latest L1 coil is 100 turns on a 43mm diameter pvc plastic pipe.
L2 wound on 70mm diam pipe with 240 turns.
L2 has exactly 4 times the length of wire on it as L1.
L2 is 187.2 ft.
My calculations showed that according to the present inductance of L1, about 90 microhenrys is here.
With its present length, this corresponds to about 21 mhz.
However, on attaching parrallel cap to L1 of 90 picofarads for resonance at 5.25 mhz, ( one quarter freq.)I found it resonating at 2 mhz.
This is still OK I think, as I can tune L2 to this as well.
But perhaps an even sub-harmonic frequency of the 21 mhz would be best.
Measuring output wattage.
Just a thought.
Maybe you could full wave rectify the output of L2, smooth it with a cap, then put two seriesed resistors across this output as a voltage "divider".
Choose appropriate resistors so that the one you connect the scope to is within the voltage range of the scope.
Measuring voltage of this DC should then allow you to calculate the current and hence the wattage.
Actually better still, you don't need the scope for this measurement - just a volt meter.
I have an old radio tuning cap. of 1.1 nan fully meshed.
I will try this as the tuning member across L2, but I have doubts on whether it will withstand the output voltage, as the proximity of the plates is so close that arcing may occur.
It is a bit of a pain having to make up many home made fixed caps. here to get required resonance.
Is this what you did?
Cap. for L1.
This consists of 11 one nan caps. (500 volt rating each) in series for 90 picofarad.
I got a shock when I paid for them - $6.00 each!!

Hi Elcheapo,
another note.
I connected up my old radio tuning cap across L2 and found the best setting for resonance (highest output voltage).
This I fed to full wave bridge rectifier, then smoothed with 0.3uf (3kv rated)
The DC voltage here is 500v.
With 1 meg load, voltage is 180 volts.
This gives the very pathetic output of 30 milliwatts !!
Back to the drawing board I think.
The AC wave form on the scope is rather ragged and jumpy as one would expect from a supply employing an arc gap which is never smooth but constantly changing.
My 3kv AC from the neon transformer is at 60 kcs. 10 milliamps max.
Please also read my last message also sent today, thanks.

Hi Stebra,
Thanks for sharing your info. Regarding the L1 circuit, there are 3 ways to connect:
1: all 3 components( S.G.-cap-coil) connected in series across neon xformer. (won't work)

2: cap connected across coil and then in series with S.G. and across neon xformer(your hookup)

3: cap in series with coil and then connected across S.G. which is across neon xformer.(my hookup)
No.3 has the S.G. connected directly across the output of the neon xformer.
I'll be trying both ways to see which is best.

You didn't mention the L1 or L2 coil length or wire size. So can't help you on the induc. calc.
I have all my electronic formulas in a QBasic program to make it easier for calculating.
100 turns for L1 seems a lot as Don only uses 5 or 10 turns. I think for max. voltage buildup and also to accomodate the larger L2 inductance, L1 should have few turns with a larger cap.
The fewer turns for better xformer turns ratio and the larger cap for a lower frequency to match up with the hi induc. L2 coil.(just my take)
Check the calc. on your 90pf cap. Here is what I get. 1nf = 1000 pf. therefore 11 times 1000 =11000pf or .011mfd
I hope you are aware that any bridge rectifiers used have to be very fast diodes of 300nanosecond or less! Ordinary silicon diodes just don't cut it at these high frequencies.
I just orderd some 100ns 20kv 100ma diodes on E-Bay.
They were $3.50 u.s. There is also good deals on H.V. caps there.
Yes I had already tried the voltage divider with resistors. With my vtvm & RF probe, the air-borne pulses just drives the meter full scale(1500v) whether or not I even have it connected. I think a regular vom would load the circuit too much.
Like you, I also tried an old radio cap to tune L2 but all I got was sparking between the plates.
Regarding your "pathetic 30 mw" here is some GOOD news.
Using a 250ma #46 pilot light across a few turns of L2 it was about half-brightness. So at a voltage of 20kv times .125 amp you get 2500 watts!
I guess high voltage is the secret.

Stebra,
Forgot to mention the home-made caps. Yes it's pain to make them up. But when you can't buy locally and in a hurry to try things then we have no choice.
For my 125 pf cap i just stole some of my wifes foil pie plates and cut out pieces about 2.75 x 1.5 leaving some tabs on the end for connection.
I then sandwiched these pieces between larger pieces of acrylic(I think) plastic cut from cd holders.
Scoring with a sharp knife allows them to break off cleanly.
But why do all this when I just bought some 1500pf 15kv caps on e-bay for $1.22 each. But then they charge you $17.00 for shipping.
cheers

Hi Elcheapo,
My L1 wire length is 46.8 ft. on 43mm diameter former.
L2 wire length is 187.2 ft. on 70mm diam. former.
I have tried many coil configurations.
The first was as Don used - i.e. 5 turns L1 and 17 turns L2 but still staying strictly with the statement that L2 has exactly 4 times the wire length of L1.
I changed to the 100 turns on L1 as Dons 5 turns with cap., only has 2.5 ohms impedence at 60 kcs input and is basically a short-circuit.
No voltage build-up here.
The 1 Nan caps (11) are in SERIES for the 90 pic.
If a regular analog-needle type meter loads the output too much, surely this is telling us that there is extremely tiny current and therefore wattage.
Typical analog meters are between 1 meg and 10 megs input impedence.
We are aiming for greatly increased output wattage to input wattage.
The radio tuning cap on L2 worked fine - no arcing, as it turns out that only 500 volts is here with no load.
180 volts with 1 meg load.
I wish I could share your wonderful projected figure of 2,500 watts as the output of L2.
If this were so, surely an appropriate resistor accross L2 as a load would quickly confirm or refute the wattage.
IF you are truly getting 2,500 watts output, or even a lot less than this, you should certainly be able to "close the loop" making a self sustaining device.
I am getting more and more sceptical about Dons claims the further I go into experimentation.
I, like so many others, desperately want his claims to be true, however there are probably hundreds of very qualified electronics engineers who have exhaustively tested these circuits and still not come up with anything workable.
Do you think we are flogging a dead horse?
There comes a time when it becomes obvious that we need to put down our soldering irons and do somthing else.
Does it not strike you as AMAZING that Don has supposedly made up not one, but about EIGHT claimed free energy devices?
The only other person who truly was in a league by himself, was Nikola Tesla
and we are still trying to ascertain IF he had an electric car and IF it was powered by free energy.
I have even resorted to using a clairvoyant to check on the validity of Teslas electric car.
The result of this was very inconclusive and many spurious details emerged from what we have been told on this so far.

Which way does it go?

@ amigo,

http://www.energeticforum.com/renewa...html#post83699

Your post here shows an exact representation of my IT.
I have been trying to make a difinative decision as to which way to pump the magnetic flux into it.

I have turned it arround two times now and started over each time with my testing.

Right now I have the center tap side going to my plasmaglobe circuit.
The other side I have feeding both sides of my 240 V circuit breaker box on my test stand. I could go on with the wiring but it is not necessary, you get the point of my arguement.

Could you give my your incite?

Thanks for your help in advance.

"Dug & Dave"?

Sorry but Donald Smith reminds me of "Dug & Dave" ala crop circle hoaxes. I.e. payed to mis-inform, part truths concerning high frequency Tesla devices. At least that is my first impression.. Hope I'm wrong.

Hope you people replicating the devices do prove me wrong, or rather confirm DS's results... Good luck.

I'll stick to Eric's teachings myself..

[baroutologos]

Few experiments.

Yesterday
..............

I received yesterday my automobile NST - Long glow input 12-15Vdc @ 5amps max output 9,5 KV @ 30mA.

Naturally, I put it to some tests, as spark distance, charging my ready made cap bank etc. One striking observation i made is the arc it enstablishes when it shorts via an arc-gap (no spark-gap). Its streamer is quite thin!

I have not any previous experience with streamers and amperage. really, how much amperage have the streamers anyway? It must be noted that this NST is electronic and its behaviour is weird.

But i have tested with an almost full load (3.8 amps input) charging the 26nF capbank and discharging via an magnetically quenched spark-gap. The NST was in series with an 50mA incadescence bulb. bulb's brightness was noted. Afterwards, the bulb was connected via a DMM to a battery and 1K potensiometer. Same rightness achieved at 30mA more or less.
...

My surpsise was that a feeble streamer, that of NST has so much power. I have seen my solid state Tesla coil. Its streamers are considerably LARGER and more energetic. Do they have more power?

Today
...........
I fired my solid state Tesla coil or "Kacher" and having another, same specs air core coil was placed near it. Second's coil end was connected via a larger bulb (100mA) to ground. I put a larger lamp cause i know that kacher's streamers have considerable amperage or the effect that amperage creates.

The free end of the receiver coil i brought it close to the toload of the kacher just to draw a streamer strong enough, but not to kill the resonance effect.
yes, the streamer, happily will travel via the second coil (11mH, 20+ohms) to the ground and bring the lamp to above its nominal incadescence of 100mA. (burned that lamp and replaced with 200mA)

Various things were tried, as to pass the current via the quenched spark-gap at the bottom of the passive coil and still having the bulb on. Etc. All worked.

I am puzzled. IS there any chance that a simple and plain TC to have enormous power on it???

I am planning to have a bridge 100nS, 10Kv, 1amp at the base of the passive coil and charge some caps and discharge them via an spark-gap. We see...
