Temporary Announcement:
Because my daily and monthly schedule(s) are becoming hectic, I may not post to these threads for an indefinite period of time.  I can occasionally take time on some borrowed computers to post Replies here and elsewhere. I do have an active thread that I started on OU.com that requires a lot less time than the preparation this Forum does.  However, I realize that that site isn't this site, obviously.
    I can take less time and spend no money to do my usual research with other electronic engineering subjects.



http://www.youtube.com/watch?v=SoXm4zuGszU =  input measurements
http://www.youtube.com/watch?v=JMbiOK85Aqk  = output measurements

The video author claimed less power in input if the circuit was loaded with something similar to a light bulb or resistor.  Output measurement give unreliable results, as the video indicates.
This is a straight forward, albeit high power, high voltage experiment.  The parts, however, are widely available or easy to build.  

(There is a lower voltage demonstration video on YouTube.) Thusly:   http://www.youtube.com/watch?v=Sd7NYx7vhd8&feature=related
Later reedit:
There's also this:  http://www.electro-tech-online.com/general-electronics-chat/106283-circuit-plans-dc-ac-inverter-output-10kvolts-3.html
(It just needs 220 VAC as a starting voltage and I can try to work around the precise frequency requirement.)

I'll have to leave this one alone for now while I build more coils for a proper demonstration.

Will return later.

Okay, to get 1200 VAC from wall-power-certified transformers:
     Take several or many and wire them in series.  Both the primary and secondary coils.  All in series.  This effectively increases the overall coil resistance and reduces average voltage across each coil turn in the whole string.   Easy.

I hadn't thought of that until I remembered my electronics classes in high school.  From decades ago.  And I only now returned to simple experimentation, especially with high voltage.  It slipped my mind 'til now.

Will return later with experimental results on this thread subject.
Okay, here they are:
I took 5ea. 273-1365's (12 VAC, .45 A), 1ea. 273-1366 (25.2 VAC, .45 A)  and 2ea. 273-1511's (12.6 VAC, 3A) and wired all in series, with primaries to primaries and secondaries to adjacent secondaries.  Secondary coils had an average of 15 VAC across their entire lengths.  1200 VAC on the wall-side primaries from one side to the other.

Two 6 Watt fluorescent tubes were lit to less-than-full brightness.  One tube by itself was fully pretty much fully luminous; having 1200 V across the whole tube length.

Adding 2000 VDC of non-polarized, 4ea. ceramic capacitors (#272-131) to one side of the tube(s) did nothing.

Adding 2ea. toilet tube inductor coils (~85 turns total) to the setup immediately above caused the tubes to brighten slightly.  This was either with or without a piece of 3/8"dia. , 3" long rebar laying lengthwise in the tubes.  No difference in brightness with the rebar.

If the tubes were paralleled, only one would light, and that was to full brightness.  With or without capacitors/inductors in series.  Same brightness.

Reedit, same day:
http://www.youtube.com/watch?v=JMbiOK85Aqk
(Output measurements based on the electrical characteristics of a 500 Watt incandescent bulb; which lights to about 1/2 brightness---getting too hot to touch in the process---and also consuming 14 mW at the output, as measured in resistance of the filament.  I'll try and look at the video again later.





NEXT:
Put 4 or 5ea. 500 Volt capacitors in series at each side of the the transformer outputs, so as to simulate a Tesla hairpin circuit.


--Lee

Reedit: 18 Aug '11:  Appended test results to previous post with self-corrected spelling and punctuation editing.
     Later added a video link describing output measurements of a hairpin circuit on same day.

--Lee
Toward that end, I rewired the whole setup to use half of the CT secondary coil in the transformers and also added two(2) ea. more in a series string.  As experienced by actual test, two ea., 6W fluorescent tubes will light to very good brightness with no other added compents in series with these.  Each tube is experiencing 1200V in series.

Next,
I'll wire more non-polarized to each side of the transformer outputs, as shown in the hairpin videos.  I don't have a reliable spark gap yet, but I'm thinking of trying several 120V neon bulbs in series or a burned-out incandescent bulb that has an open filiment to spark with.

For a Faraday cage, my unused apartment oven should work, since the whole thing is grounded with an industry standard, American 220-240 VAC, 60HZ mains plug.

Here's a more accurate depiction of a hairpin circuit:

http://s1108.photobucket.com/user/soundiceuk/media/Tesla/HairpinCircuit.jpg.html

The question is:   Is more voltage at the end of the circuit translatable into more power when a half wave bridge is used as a power tap-off means?   Or does the circuit act as a transformer and display to same power along the length of the vertical 'ladder'?

Hi Lee, The way I see it from a layman's point of view, the hairpin circuit is a version of the "Lecher Lines" http://en.wikipedia.org/wiki/Lecher_lines.

I think that utilizing the energy of the waves will result in a kind of "constant current" effect, meaning that only a certain amount of power at a certain rate per cycle could result, which would be governed by the input power per cycle and losses, impedance matching ect.. I have not seen any demonstrations of more out than in with such an arrangement and considering the amount of experiment time people have put into the devices I doubt there ever will be.

I think it shows that a standing wave requires a "counterpoise" of some kind to utilize the power directly with wires to the load, and cannot live on a single conductor without the support of the another conductor (natural media or a wire as such).

Basically the load cannot draw directly from the supply unless the first wave is tapped in an appropriate phase. any waves removed from the supply (in distance) will have no direct effect on the supply even if shorted.

This is just a layman's point of view, I see no way the load can draw directly from the supply so the load can only tap the energy of the waves themselves. If it was OU Tesla would have said so in my opinion. He could recognize free energy when he seen it and had no qualms saying so.

Cheers

P.S. Just to add I think in a removed kind of way a single turn primary loop tuned to 1/4 WL resonance is kind of the same as a hairpin circuit with only the shorted bar are so short only a 1/4 WL fits on it.

Farmhand,
Good to hear from you...

Concerning your posted Reply #5 on this thread, I took a look at the Wikipedia article you provded and saw the Lecher circuit looked a lot like what was attributed to Tesla---whatever his 'hairpin' circuits were at the time.   Odd.   Single wire transmission was what I remember being claimed on an Internet site article a few yrs ago I looked at.   But, I was relying on memory alone, here.   It might have been a double, parallel wire setup like the Internet Lecher circuit, after all.   And it was deliberately shorted at the far end by a working, brightly shining krypton tube.   They usually start off with at least 4,000 Volts as a trigger charge to initiate an ionized spark as a spark gap to the rest of the tube.   (I notice that article appears to be gone as of now.)

What I tried to find again on the 'Web was a circuit to replace spark gap in a long wire ambient radio energy collector with a straight fluorescent tube.   Less voltage and a shorter wire should be needed.   I have the required parts to begin experimentation now.   I do have a hand-drawn circuit to follow; but I was looking for Internet corroboration of what I was asserting.

You presented an interesting concept in your reasoning.   I hadn't heard of that yet.   (My time doing electronic engineering was limited until recently.)   Good thinking.   Thanks for the input; I'll continue looking at the 'Web for more info.

--Lee
